Initial Setup
Before plugging speakers into the card, check the Master volume control is at a reasonable level, but not at maximum (you might damage your speakers, or worse, your ears).
Also check the following controls are unmuted (and set to reasonable levels):
- PCM
- Synth
- CD
Controls
The following is a partial list (it ignores Capture controls):
- Master
- 3D Control - Switch
- PCM
- Synth
- Line
- Line-In Mode
- Rear Output
- Line-In
- CD
- Mic
- Mic Boost
- Phone
- IEC958 5V
- IEC958 Copyright
- IEC958 In Monitor
- IEC958 In Phase Inverse
- IEC958 In Select
- IEC958 In Valid
- IEC958 Loop
- IEC958 Mix Analog
- IEC958 Output
- on - for digital output
- off - for analog output
- PC Speaker

The Master control on this card is purely a volume control (it has no 'mute' switch).
Troubleshooting Hints
No Sound from Analog Speakers
If you hear no sound when using this card with analog speakers/earphones, try switching off the following:
- IEC958 Output
- Exchange DAC
These can be switched off using alsamixer, amixer or other available mixers. (Tested using Debian 4.0r6, alsamixer v1.0.13 and headphones connected to the SPK jack socket.)
