[Pkg-alsa-devel] Bug#372554: alsa-base: Do not make snd-usb-audio the default hardware

Package: alsa-base
Version: 1.0.11-2
Severity: wishlist

Hi!

I have a laptop with an AC97 soundcard, and an USB webcam with an integrated microphone.

If I boot my computer without plugging the webcam the AC97, soundcard is used by default by ALSA when loading snd-intel8x0. But if the webcam is plugged snd-usb-audio is loaded before and thus the microphone is considered as the default... and the sound doesn't work anymore!

This could be corrected by appending at the end of /etc/modprobe.d/alsa-base: 
options snd-usb-audio index=-2

Ask me if you need more information or tests.
Thanks!
