6-24-2004 Anyone have any luck getting multi-channel output from NForce2? Alsa works great to get output on the standard headphone/front output, but I can't get any sound on the other outputs. /proc shows me that it's setup 2 pcm outputs (0,0 and 0,2) but the second does not produce sound on any channel... Running Kernel 2.6.6, Alsa 1.04rc2

Can't run TeamSpeak and Quake3 at the same time!! Is There something I miss??? I allready ready Teamspeak who-to and linux-gamers who-to but I dosen't work PLEASE HELP! Debian sid NForce 2 MCP

Thanks **

Is there any easy-to-understand, well written documentation available? I need a numbered, step-by-step, list of instructions to follow so I can figure out how to turn on the sound on my linux red hat 9.0 optiplex gx270 system.



I am using a Soltek SL-B7A-F board with a NForce2 chipset. Sound plays just fine with ALSA 1.0.0 RC2, but I need to passthrough sound coming from a DVB-card. Therefore I would plug the line-out cable of the DVB card into a line-in on the back panel - but the mainboard manual says these are front, back and LFE channels. Two more ports are on the front panel, labelled mic-in and something like input/output. Unfortunately I can't plug the DVB audio source into one of these ports, the cable ist just about 20 cm long ;/

Can I switch one of the ports on the back panel so it acts like a line-in? I don't want the cable go to the front, and since any soundcard always had an input on the back, I think this should be possible...


Hi people, and thanks to all people thats will lose time to help me. i've a P4C800 Deluxe with (i suppose) a I8x0 audio card integrated. (lspci)-> 00:1f.5 Multimedia audio controller: Intel Corp.: Unknown device 24d5 (rev 02) I've read some thread about my audio card and follow some "FAQ" that can help me (as they said) but my card doesnt work. I've try with OSS ad ALSA driver, down here i will past dmesg messages: (alsa)-> Advanced Linux Sound Architecture Driver Version 0.9.7 (Thu Sep 25 19:16:36 2003 UTC). request_module: failed /sbin/modprobe -- snd-card-0. error = -16 PCI: Setting latency timer of device 0000:00:1f.5 to 64 AC'97 0:0 analog subsections not ready intel8x0: clocking to 48000 ALSA device list:

Has anyone gotten 6 channel support to work with the nForce2 on the A7n8X Deluxe? --- Will this driver support the Asus P4P800 board with the intel ICH5 chipset? Someone lower down says it needs the CVS version for another P4P board, is that still true?

-> I have a Asus P4C800 board and it works. I have Debian testing installed. But I have problems with playing Audio-CDs with Kscd. The sound is ok, but the System freezes from time to time a few seconds. UPDATE: My problem is not related to the intel8x0-driver, it seems to be a general problem with the cdrom drive.

Hello, someone, apparently, maliciously deleted this wiki-page, so I went through the history, and ressurrected it.


Teamspeak + nforce2 builtin audio, how to use virtual sound channels ?

ie i need a device (/dev/dsp)? for quake3 and i need a device (/dev/dsp1)? for teamspeak and so on ..

how to achieve this with alsa drivers ? tks

1- i read this and i read this

so the status is, i tryed the aproach given there but that doesnt work, and after reading the 2nd post im more confused. I did searched google, and i dont find nothing niet rien nada, just people complaining about the same problem Quake3 will not open /dev/dsp when TS is running. And no one seems to know the answer.

\ 2- another strange bit i get its to initialize quake3 with

quake3 +set s_initsound 0 I can start the game, without no sound ofcourse, but with TS sound. I can play skirmish mode, or single player, and listen ppl speaking on TS, but as soon as i get online or switch to another quake3 mod like reaction quake, urbanterror, OSP etc the game starts, ie the map loads, i can move the mouse 360º i can switch/change gear, etc, but as soon as i press forward right, or to go left the game will crash with

Welcome To Urban Terror 2.6 Received signal 8, exiting... Shutdown tty console

a mem related problem ? probably, but this happens in 2 diferent OSes, so itnst a ALSA problem afaik

anyhelp would be appreciated. tks

From [email protected] : I have exactly the same problem and i didn't manage to solve it yet...


Gericom Laptops:

They have the SiS chipset, but the intel8x0-driver bundled with alsa-0.9rc6 does not work. I can only play sound from CD.

The PCM does not work. The Mixer does work though, muting/unmuting the master volume produces klicking noises on the speakers.

This problem was solved in the latest alsa build from cvs (and alsa version later than 0.9rc6, I suppose...)

Thanks to the alsa guys and also to Gericom which provided a commercial license for OSS commercial drivers to its customers (though it's commercial, it was great that a company make an effort towards its customers who want to use Linux !)

Gigabyte 8SIML Motherboard onboard SiS7012 soundcard:

Digital out seems to be locked at 48Khz, great for dvd playback, but when playing back an mp3 in Xmms at 44.1Khz, the digital out gets disabled.

The windowz driver manages to switch the digital out to different rates, so it can't be a hardware issue.

Toshiba S3000-X4

ALSA docs say it is locked at 48000Hz, but it worked fine for me with XMMS at any rate.

However, it does not work with 0.9rc6. I am seriously considering downgrading to rc5 or the "stable" branch.

The Nvidia nforce2 motherboards use this chip for their onboard sound.

I've found that xmms plays mp3s too fast though. Is there an option to force it to do 48000 playback?

UPDATE: The nForce chip doesn't use this chip for it's sound, it uses the same programming api as the nForce APU is a much better chip than the intel. Also, I managed to get the nvaudio kernel module from nvidia to compile and it works a charm.


You can manually set the ac97 clock by adding to /etc/modules.conf (or equivalent):

options snd-intel-8x0 ac97_clock=41194

However. with an nforce2 board, the playback speed cycles between normal and too fast every time the sound device is closed then opened again. This is much better then previous releases (or the OSS driver) which changed speeds in mid-song, but it's still nagging.


Has anyone gotten SPDIF passthrough working with the nForce2 (found on A7N266-VM mobos) chipset?

I don't think that motherboard got a nForce2 chipset. According to my manual it's a nForce chip.

Has anyone gotten SPDIF passthrough or capture to work with a Suttle SSG51G? The 0.95 driver has got IEC958 controls in alsamixer but they have no effect. Any help much appreciated as this has been driving me nuts for weeks.

I'm another user and I'm also having this problem with Alsa 0.9.2 driver on Shuttle XPC SS51G. I can make changes with the IEC958 controls in the alsamixer (and alsamixergui) that show up on the mixer form but they have no effect on the sound output from the front SPDIF connection (SPDIF output works fine with Windows XP--system is dual boot). It really is frustrating.

UPDATE 2003-07-31: Problem is SOLVED. Thanks to a tip from Ole Andre Schistad ([email protected]) on the web site under documentation for the Intel i820 card options. The solution is to compile the ALSA drivers, libs and utils with "cvscompile". According to Ole, "The S/PDIF support in this chipset currently requires a CVS version of ALSA...the required device under /dev/alsa is not created with the "release" drivers..." I'm using ALSA version 0.9.6.

2003-08-19 Yes, cvs makes the IEC958 Passthrough work, however on my MSI Mega 651, it refuses to send Analog to IEC958. I have obviously enabled this option but it's still empty sound, analog is still being output so it does in essence fully function but requires 2 connections and sometimes manually switching your receiver.

22 Feb 2004

I use alsa 1.0.0rc2 and MSI MEGA, and i get pcm output from xmms, esd, and others to optical SPDIF only after i run this:

  1. iecset audio on

after that i can use pcm and 5.1 output from dvd player to optical SPDIF!


I can't get this to work on ASUS P4P800-VM. alsamixer reports the driver and the AD1980 codec (SoundMAX) but I have no sound on neither RCA ports.



I find some solutions to play correctly mp3 at any rate to the spdif output (intel810 on a Nvidia NForce2: Shuttle SN41G2).

Of course you should use ALSA CVS version and set correctly alsamixer.

All solutions use resampling methods:

  1. solution 1 resampling at mp3 stage

lame rox.mp3 --resample 48000 - | mpg123 -s - | aplay -v -c2 -f S16_LE -r 48000 -D spdif

  1. solution 2 resampling at pcm raw stage

mpg123 -s rox.mp3 | sox -t raw -r 44100 -s -w - -t raw -r 48000 -s -w - resample | aplay -v -c2 -f S16_LE -r 48000 -D spdif

  1. solution 3 use mplayer

mplayer -srate 48000 -ao alsa9:spdif rox.mp3

The last solution consist in using alsa-xmms plugins and xmms-crossfade plugins - with xmms select Crossfade as the output plugin - configure It to use the alsa-xmms as the output plugin (not the builtin oss) - change the sample rate to 48000 Hz - then configure the alsa-xmms to use the spdif (select User define: and write spdif in the field)

Hope it will work with you... enjoy ;o), Damscot.

UPDATE 2003-07-31: Problem is NOT solved for me. The solution is to compile the ALSA drivers, libs and utils with "cvscompile".

=> not work for me i have shuttle SS51G Can you send your asound.state and your mplayer param for play DVD please? maybe your /root/.asoundrc too ? maybe is my fault ?

Audio problem on Dell Dimension 4600

I am working on the audio solution for this PC running RH8.0. So far I have not got one note out of it.

The Intel site suggests for RH8.0 linux and this motherboard (Intel D865PESO) to use the driver, ADI Integrated Audio Driver?[alsa_driver_0.9.1adi_rev5.tar.gz]. This driver installed OK as per instructions. I have also installed alsa-lib-0.9.1 and alsa-utils-0.9.1.

The sound modules load with modprobe (I check with lsmod) but do not work, for example, if I try to play an mp3, I get the message

"couldn't open audio; Please check that 1. you have the correct output plugin selected 2. no other program is blocking the soundcard 3. your soundcard is configured correctly OK" (I do not know how to do any of these 3 checks).

The KDE utility "system settings/soundcard detection" says: Vendor: unknown vendor Model: generic snd-intel8x0 device Module: snd-intel8x0 "test" produces nothing; an audio cd likewise.

I ensure the mute is turned off by running alsamixer. I also tried: amixer -c 0 sset Headphone,0 55 unmute and for speaker jacks: amixer set PCM 100 unmute

Dell has informed me "the 1980 audio solution uses the AC97 2.2 compliant digital bus from the ICH5 and the Analog Devices ADI1980 AC97 CODEC."

However it seems clear the motherboard is the Intel D865PESO model, and the Intel website shows this model uses the Analog Devices AD1985 codec, not 1980.

I have also tried using alsa_driver_0.9.6.

Any suggestions for further action would be much appreciated.



Even easier to 'fix' the output frequency: use esound. Launch with 'esd -r 48000', and have all programs output to esd. All works fine!

(on an Asus L3000D laptop)


Alternative fix for the output frequency, using artsd (enabled by default in KDE): add the option "-r 48000". Unfortunately, in KDE3 you cannot set this with the graphical control center. Here is a two steps receipt: 1) start the sound system control center (Settings->Control Center->Sound & Multimedia), modify any option and apply it (this will create your config file) 2) edit the \$HOME/.kde/share/config/kcmartsrc file and change the line Arguments: Arguments=\s-F10 -S 4096 -r 48000 -s 60 -m artsmessage -l 3 -f


(tested on KDE 3.1.4 and ASUS L3000D laptop)


Hi, I am having massive problems getting my nForce2 APU to work, it's easy enough to get it to work with arts, but, alsa, no go. If i set arts to use OSS there is no errors and it works, but the problem is that only one device can use OSS at once. I have tried to use the alsa driver snd-intel8x0 but it returns that it cant find the card, I also tried using the nvaudio driver with which alsa sesms load properly but when i try to use it i get a "unable to open default device" error, also when I "cat /proc/asound/cards" it returns "no soundcards". Everything else works, video, IDE, TV card, just not sound. :(

Please please, I am getting desperate, please contact me at [email protected] if you can help, I am using Debian 3.0r1 Woody with a 2.4.20 kernel (I compiled for the nForce2 chipset).

PS: I am very much a linux noobe.

here is my modules conf: alias char-major-116 snd alias snd-card-0 nvaudio alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss options snd snd_major=116 snd_cards_limit=1 snd_device_mode=666

Hi, I've got quite similar problems with sound as [email protected]; I have an Epox 8RDA3+ with C-Media sound chip. Sound works when loading the kernel modules ac97codec and i810_audio, but only for OSS output. That's not enough, because if arts is playing sound, xmms can't access the sound device. If someone has a solution or knows a howto for this, please tell it on this Wiki site. Thanks.

11-19-2003 (19.11.2003) to [email protected]: AFAIK nvaudio is an oss - module, not an alsa module. You should decide to use either OSS or ALSA, not both. If you can use arts you shouldn't need any more. Arts does mixing in software and sends the mixed stream to the driver. (Only the arts deamon opnes the device, all audio apps should send their data to arts) Configure XMMS to use an arts output plugin - this should be enough. ARTS output plugins are at

I have an Epox 8RDA3+ as well. I get sound with Alsa 0.9.6 when I use ALSAs' OSS emulation . Without the OOS emulation, I get: ALSA snd_pcm_hw_params_set_period_size error: Invalid argument. I haven't yet figured out what that means. The other issue here for me is that the AC97 codec (the C-Media CMI9738 chip itsself) does not have a hardware PCM-out volume control. So I get sound but can't change the volume.

04-21-2004 (21.04.2004) from: [email protected] >>Arts does mixing in software and sends the mixed stream to the driver But I know that the nforce2 APU can do hardware mixing, hell, even windows can!. Software mixing is just slow and bulky, and doesn't help as arts can't be used with the games I run (AA). To overcome this limitation I have installed a SB Live and disabled the onboard audio, but this is only a temporary workaround. Since my last post I have tried using gentoo (Great falvor), it even includes all the nforce support in the kernel by default, I had sound & video working with no problems, except for only 1 program can use /dev/dsp at once. Also, it has been a few months since I last checked the nforce drivers from nvidia, the latest version may have fixed this problem. PS: I have given up with alsa, it is easer to use the OSS drivers.


Did anyone get ac3 passthrough spdif working on a dell inpiron (8200) laptop ?? I got spdif working only i can't get the ac3 (Dobly digital) passthrough spdif working...

I used 0.9.7 and the cvs releases , no luck :(


I have a new motherboard with built-in audio (DFI PS83-BL with C-Media 9739A). Kudzu recognizes it as "Intel Corp.|82801EB AC'97 Audio" and assigns the snd-intel8x0 driver to handle it. Problem is, I cannot control the volume on audio generated from the CPU. For example, from XMMS. In ALSA 0.9.2 and my SoundBlaster card, the PCM control controlled the volume for XMMS. I installed ALSA 0.9.8 and the PCM for my current audio chip is a binary control! That's right: I can turn it off and on. No settings in between. Does anyone know what the story is on this? Thanks.



I have a SiS 7012 (i8x0 compatible). I know that it is a cheap piece of chip (some people may say that it is just a piece of s**t :). But i still dont know if it is easy to use Full duplex, Software or hardware pcm volume setting, the midi port... say with alsa (nor with oss?).


I seem to have a similar mainboard (mine is ASRock). Very cheap thing with many problems afaics. Could you explain, how you got yours working fine? Any problems? What ACPI-Options did you set? I get a bit of sound with the oss kernel driver, but very very lacky. I'm currently trying to set up alsa, but still can't hear anything. One error I get is the following

aplay /usr/kde/3.2/share/sounds/pop.wav # wait 10sec here for output to be displayed Playing WAVE '/usr/kde/3.2/share/sounds/pop.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

  1. wait another 10sec

any ideas? any help?

11-18-2003 The "can't change volume with C-Media 9739A" is a hardwar issue. The chip itsself does not have a hardware PCM-Out volume control. The only thing you can cahnge in the relevant register is the mute bit. Thats's why some mixers represent it as as binary switch, checkbox or similair. I was wandering if one could use alsa-libs module architecture to do volume control in software. Haven't figured that out yet.

11-26-2003 Any news on the C-Media 9739 alias 82801EB issue? I also have the on-off effect... And: only the FRONT-out works. Don't know how to acitivate REAR and SUB.

12-03-2003 Got the same MB : DFI PS83/BL with i865pe on mandrake 9.2 with alsa the i8x0 driver gives no sound at all... (kernel 2.4.22mdk-smp) the insmod returns error of unresolved symbol and so on... any idea ?

12-03-2003 I'm having some weird problems with my SiS 7012 card, when I try and run StepMania (It's a DDR emulation program) I get this error.

ALSA: Advanced Linux Sound Architecture Driver Version 0.9.6. ALSA Driver: 0: SiS SI7012 [SI7012], device 0: Intel ICH [SiS SI7012], 1/1 subdevices avail Couldn't load driver ALSA9: Driver unusable (not enough mixing streams) Sound driver: ALSA9-sw

And then the sound plays all warped and messed up. However, in XMMS and whatnot, while using the ALSA plugin, there aren't any problems and playback is perfect. When I try and play an .mp3 with mpg123, using the ALSA driver, the sound is messed up (its a little different than StepMania, but its static-y all the same) and I have a feeling its a similar problem. Unfortunately mpg123 doesn't give me any errors about it. I had a feeling it was because my sound card is a pos, but I don't know how to go about setting it up. It seems that it knows what card to use, so I don't understand the problem. And ideas?

Jan 02, 2004

Hullo. I have problems with an old A7N266-C mobo. My sound is all jumpy, Winamp3 statics all the time (W3 linux build 488). Anyone has a clue on this?&

Jan 07, 2004

Hi! I have a nForce1 mobo and I'm trying to use alsa (kernel 2.6 built-in) with the intel8x0 driver. I get no error messages and /proc/asound shows the card (and yes, I have unmuted master, pcm,... in alsamixer), but I can't play any files (I can play CDs, though). The pcm slider in KMix keeps dropping to zero... Thanks for any help!

Jan 21, 2004

I have an SIS7012, Debian unstable,Using Alsa driver 1.0.1 compiled through 2.6.0. Alsa libs 1.01. Application independant problem

All audio other than CD audio is scratchy with pops. I have tried upgrade, downgrade etc all to no avail.

Aside: xmms crashes on using alsa output so i use esd.

 The sound quality was fine but seemingly without reason has degraded.

Any advice as to how i can solve this prblem is greatley apreciated


Jan 21, 2004

I have problems getting the mixxing to work with my cmedia 9739A based via kt-600 based msi-delta fisr motherboard. It is really annoying, is there any work in progress or should i look for another soundcard?


Feb 13, 2004

I installed 0.9.4 alas on a Debian box with an Asus P4P800 motherboard. Followed these instructions, turned up the mixer and get no sound. The sndcard is identified as "Intel 82801EB AC97". Any output to /dev/dsp hangs for a long time, and then it starts going. Xmms gives me nice little bars going up and down. Still no sound. Tried many permutations. Kernel version is 2.4.20. Would prefer not to upgrade since it's got all the nVidia extensions installed and working.

Is it time to slap an old sound card in?

Hi, I have a Gigabyte 8Knxp which is nearly similar to the Asus Board, 00:1f.5 Multimedia audio controller: Intel Corp. 82801EB AC'97 Audio Controller (rev 02)

i got the sound to work after many hours. I tried the dmix howto, i can now play 2 sounds at once. I installed the latest alsa drivers on debian/sid. The main problem is that i have no Microphone input, and can´t use quake3 while xmms is running, it hangs at the sound initialisation.

cat /proc/asound/pcm 00-00: Intel ICH : Intel ICH5 : playback 1 : capture 1 00-01: Intel ICH - MIC ADC : Intel ICH5 - MIC ADC : capture 1 00-02: Intel ICH - MIC2 ADC : Intel ICH5 - MIC2 ADC : capture 1 00-03: Intel ICH - ADC2 : Intel ICH5 - ADC2 : capture 1 00-04: Intel ICH - IEC958 : Intel ICH5 - IEC958 : playback 1

I think the main problem is, that the Linux driver handle all the connectors on the back in a other way than windows. But i tried all of them and none worked for me. Is there a script or tool that installs and configures a working multisource playback? thx for your site! PS: the sound goes over into noise after ca. 10 minutes, when i start a new song its ok for a while. if you have tips. mail me: [email protected]

February the 14th 2004


I have problems in geting the SPDIV to work. I have a Asus OEM board with SiS7012. I installed the alsa-CVS version on my debian system.

I want the chip to use spdif als well as the normal output. I dono what i did wrong or what i forgot. The M\$-Programloader can manage that so i hoped i can do it in linux too. Cauz the singal via the optical-out is much better then the analog.

i also have another problem. the mixer discards my volume-setings after every reboot and i can't find out why.

i u can halp me plz contact me at chris_[email protected]

thx Chris

William Blew: I have my nforce2 board's S/PDIF optical output working from both the alsa and oss APIs with the ALSA 1.0.2c drivers.

For comparison, my configuration is an ABIT NF7-S rev 2 mobo. This board uses the nforce2 SPP chipset with a MCP2-T southbridge.

I am using my motherboard's optical S/PDIF output to connect to my digital home speaker system from Cambridge SoundWorks (the DTT3500).

I am using a linux kernel 2.6.3 that includes alsa-driver 1.0.2c.

I have installed alsa-lib, alsa-oss, and alsa-tools 1.0.2. The trick to get the OSS emulation working is that our motherboards' optical S/PDIF is the pcmC0D2p device. However, ALSA's oss emulation defaults to using pcmC0D0p. Hence no sound by default. :(

For OSS emulation device mapping:\~iwai/OSS-Emulation.html

I use Gentoo Linux with devfsd (hence some unusual alias entries in my modules.conf). Here is my modules.conf file. The options for snd-oss-pcm is the key piece of magic, as they map the oss devices to the pcmC0D2p device instead of the default pcmC0D0p device:

options snd cards_limit=1 alias /dev/snd snd-card-0 alias /dev/sound snd-card-0 alias /dev/sndstat snd-card-0 alias char-major-116 snd alias snd-card-0 snd-intel8x0 options snd-intel8x0 mpu_port=0x330 options snd-pcm-oss dsp_map=2 alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-slot-1 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss

In addition, the following enables a software mixing, rate converting device for ALSA interfacing applications, the alsa device is "nforce".

It differs from the www wiki sites in that it uses hw:0,2 (not hw:0,1):

pcm.nforce-hw { type hw card 0 } pcm.!default { type plug slave.pcm "nforce" } pcm.nforce { type dmix ipc_key 1234 slave { pcm "hw:0,2" period_time 0 period_size 1024 buffer_size 32768 rate 44100 } } ctl.nforce-hw { type hw card 0 }

The mplayer (as of version 1.0pre3) can be used with the above configuration:

    mplayer -ao alsa9:nforce <other_options> <file>

Alternatively, its oss driver can also be used:

    mplayer -ao oss <other_options> <file>

BTW, with my setup, I have the outstanding sound issues: 1) AFAIK, alsa's mixer doesn't affect the output in any way. 2) xine's alsa support doesn't seem to work with this config 3) various media players' (mplayer 1.0pre3 and xine) S/PDIF passthrough (aka hwac3) don't work.

I hope this helps.

I got exactly the same main-problem: the alsamixer doesn't affect the output in any way (I'd like to regulate the analog output)

my hardware: nforce (ep-8rda3i) my kernel: linux kernel 2.6.3 (alsa-driver 1.0.2c.)

So my main question is, if this is an hardware/alsa problem, or if i just made some configuration mistakes ?

Have been tearing my hear out trying to get Alsa drivers working on ASUS P4P800S board. After runninging in circles recompiling etc etc etc like everybody, found a ref on a forum about multichannel and this chipset. Had the idea to plug speakers into Mic jack, hey presto it all works. I am running MDK 10beta2 with kernel 2.6.2 May be someone knows how to you can fix this err, bug/oversight?

hope this helps peoples stress levels :-)

Here is my sad experience:

NForce2 (WinFast K7NCR18D-Pro) kernel 2.6.3 alsa 1.0.3 all parts (also tried 1.0.2c which came with kernel + 0.98 userland)

It works but the quality is evasive.

'alsaplayer -o alsa song.mp3' may advance through the song \~10% faster than it should, or may work in sync - depending on the players which were run before it! When it plays at normal speed, high pitches appear err....cracked.

'aplay /mnt/c/WINDOWS/Media/Windows\ XP\ Logon\ Sound.wav' sounds really distorted though presumably at proper speed (it is 22Khz)

And everything sounds as ugly as if it was resampled several times back and forth with quality losses.

If I create the file .asoundrc with the contents (as suggested at the non-wiki card page): pcm.nforce-hw { type hw card 0 }

pcm.!default { type plug slave.pcm "nforce" }

pcm.nforce { type dmix ipc_key 1234 slave { pcm "hw:0,0" period_time 0 period_size 512 buffer_size 4096 rate 44100 } }

ctl.nforce-hw { type hw card 0 }

Then aplay segfaults. I tried all suggested .asoundrc files from i8x0 page (that redirect default to dmix), and they all segfault. Though, I can run several parallel 'alsaplayer -o alsa -d plug: dmix song.mp3' processes.


P.S. Got an SB Live yesterday. All the mentioned problems disappeared into thin air. ;-)


Regarding: "alsa 1.0.3 all parts (also tried 1.0.2c which came with kernel + 0.98 userland)"

I recommend using 2.6.3 with its natively provided 1.0.2c alsa-driver set and with the 1.0.2 alsa userland packages (alsa-libs and alsa-utils in particular). I have had some success with those versions. With 1.0.3 userland packages, it crashed with my 1.0.2c drivers and I can't get the 1.0.3 drivers to compile on my Gentoo Linux boxen. :(

Regarding compilation of 1.0.3 drivers at Gentoo:

symlink /usr/src/linux/arch/i386 as /usr/src/linux/arch/x86

and emerge it:

FEATURES="-sandbox" ACCEPT_KEYWORDS="\~x86" ALSA_CARDS='intel8x0' emerge --buildpkg =media-sound/alsa-driver-1.0.3


How can I make my IEC958 work? On a COMPAL CQ-12 laptop:

but the playback does not start if I select it. xmms loads the music r whatever, and then it stops. The spectrometer doens't show activity. Also, in alsamixergui I can't switch it on (frozen bar)

What is this IEC958 and what can I use it for/how can I use it at all?

I have a Shuttle SN41G2 (nForce)and I recently installed Fedora Core 2 Test 2 (2.6.3 kernel) and 1.0.4rc2 ALSA on it. I can use aplay to play a .wav but I can't get xine to play any audio at all thru the SPDIF output. Here's my config. Please help.

Shuttle SN41G2 guy,

In Xine try setting your audio devices to hw:0,2

All of them, then restart xine, and if you are lucky (like me) it will work.

Hope this helps a bit.

I'm on Fedora Core 2, with a custom 2.6.6 kernel, and a nforce2 board trying to use spdif out.

I've got the output for oss and alsa working perfectly with William Blew's configs above, sound quality is excellent. But i've got the same issue as a couple of other people in that I can't control the volume.... which is slowly driving me insane, as this is for an HTPC box, and by amp is one of the ones that is apparently higher quality because it has no remote control... so i have a stick for changing the volume while watching TV :/

Darren B.

For people who want to use several OSS compatible applications with ALSA at the same time, I suggest using the dmix plugin and aoss with the OSS emulation in ALSA enabled.

For howto use dmix as default:

Howto use aoss: just execute: "aoss quake3" or replace quake3 with your program name. Aoss is part of the alsa-libs and can be found here:

When everything is configured you can use many applications at the same time thru aoss and oss emulation.

Hope it helped!


For everyone who's missing volume control with his CMedia 9739 onboard sound chip, here are the facts I found out so far. This chip is used at least on Epox 8RDA3+ and maybe in every newer nforce2 chipset. (Who knows where else it is used?) The general problem with the 9739 is that it doesn't have a volume control in hardware. As the technical reference (avail. at states, there is no PCM volume register on chip, only a PCM muting register. Strangely, it also states that there is a _Master_ volume register where you should be able to set the volume (not only muting)! But I had no success using it; changes to that register have no effect. Maybe this is a hardware bug, or the tech reference is wrong. BTW. CMedia's OSS driver does volume control in software, so they know about the problem... So it seems that the best solution is to use some kind of software volume control.

To get the chip in fact working under Linux, there are several possibilities:

Pro: mostly works (stable etc.)
Con: you need an external volume control; and it's not very elegant :)
Pro: works; and the sound daemon has volume control
Con: not every app supports those sound daemons (but xmms and mplayer do); you have one program more running in background; the daemons are not always reliable (that's my experience); you need to use a specific program for setting the volume (eg. kmix)
Pro: built by manufacturer :) ; has built-in volume control
Con: only usable with old OSS (Open Sound System), AFAIK not usable with ALSA; didn't work reliably for me
Pro: it does work really well (if you buy a good card and not an el-cheapo for 9.95 EUR which features as chip a 9739 :)
Con: additional costs to your PC; takes a PCI slot

BTW. I think I also tried the nforce2 soudn driver; it worked stable, but had no volume control as well...

Well the (probably) best solution would be to integrate generic software volume control in ALSA; that means to write an ALSA plugin that does about the same as CMedia's driver does: rescale every sound sample to the desired volume. CMedia's driver is under the GPL, so their algorithm could be used. I've heard that such a plugin is planned, but I don't know about the current status. Ask at Alsa-devel mailing list ( about it. More about ALSA plugins:

Good luck, Oliver

Hi, I just want to give a short summary about my experiences using this soundcard on my Dell Inspiron 8600 (BIOS version A08). I am using the recent kernel 2.6.7 (vanilla) and alsa works perfectly with my soundcard. Then I tried to enable acpi to get e.g. the status of my battery. ACPI is working fine as well, but then I got irq conflicts with my soundcard. Error message seen in dmesg: unable to grab IRQ 7 Intel ICH: probe of 0000:00:1f.5 failed with error -16

The reason is that after I enabled acpi, acpi is on irq 9 and parport0 (lpt1) is using irq 7, which conflicts with the irq port of my soundcard (cat /proc/interrupts). Usually pci devices can share irq's. But lpt is an isa device and so it cannot share it with intel8x0. It's a problem of the bios which handles the irq interrupts in a bad way.

So for me, I solved the problem by disabling the lpt port in the BIOS settings.

If anybody has a better solution pls mail to "internet at"

Good Luck, Jonas



Just wanted to report success with SPDIF and AC3/DTS pass through.

I'm using the on-board sound on my ABIT IC7-MAX3 mobo. It's a RealTek ALC650, for which I'm using the snd-intel8x0 module.

alsadriver is 1.0.5a, but I suspect that's not terribly important.

I had a lot of trouble at first. In the end, my main problem was finding how to properly mute the "Analog to IEC958 Output" setting. The gnome-alsamixer didn't seem to do this, but alsamixer did (use the m key to mute).

Now if I can just get 1080i working with my HDTV... :)

-- Buck

Update 10-July-2004

It seems I was mistaken. I have yet to figure a reliable way to get SPDIF to work. I can get it to work by fiddling with the mixers, but I don't know the exact sequence that does the trick.

-- Buck

14 Dec 2004

No rear channel audio output if 'IEC958 Input Monitor' is on

Unmuting the 'IEC958 Input Monitor' mixer control on Intel ICH5 with the Realtek ALC650F chip leads to loss of audio output at both the rear channels; not sure whether this holds true for other chipsets supported by snd_intel8x0. Make sure to _mute_ this control if you don't need it.
