The order of my cards changes whenever I reboot or as devices are plugged and unplugged. How can I create PCMs that refer to cards by name instead of number?
On the LAU Clemens Ladisch wrote: Make sure that all drivers have the "index" option in /etc/modprobe.conf (or whatever your distribution uses), e.g.:
options snd-intel8x0 index=0 options snd-emu10k1 index=1 options snd-usb-audio index=2,3
Christoph Burger-Scheidlin added: You can refer to the cards by the name that is displayed in the /proc/asound/cards file. My /proc/asound/cards file is...
0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with AD1981B at 0x24000800, irq 11
1 [Modem ]: ICH-MODEM - Intel 82801DB-ICH4 Modem
Intel 82801DB-ICH4 Modem at 0x1400, irq 11
and the respective entries in my /etc/asound.conf are:
# CARD DEFINITIONS
pcm.intel { type hw; card I82801DBICH4 }
ctl.intel { type hw; card I82801DBICH4 }
pcm.intelModem { type hw; card Modem }
ctl.intelModem { type hw; card Modem }
