Comment 0 for bug 68128

I have an iMic usb audio device. the built in sound card on the machine is disabled in BIOS.

under dapper the iMic was the default device. after upgrading to edgy the iMic was given device index 1, an so is no longer used by sound playing apps.

commenting out the line
options snd-usb-audio index=-2
in
/etc/modprobe.d/alsa-base
restores the dapper behaviour.

I understand that this change was made to fix #31109, #46996, #46998 in alsa-driver (1.0.11-5ubuntu1).

in the case of a real usb sound card, surely it should be the default sound card. why would i plug one in if i wanted to use the built in sound.

in edgy:
sam@flute:~$ cat /proc/asound/cards

in edgy with the line commented out:
