Sound Card changes after every reboot

thatnewyorker · 2012-03-27 04:11:09

Alright, I've had this little issue since I installed Arch on one of my computers. After every reboot, the sound card changes and I have to manually edit my .asoundrc to get sound. It's not a huge deal but it is very annoying. How do I prevent my system from switching my sound card?

This the output from aplay -l

I'm trying to keep the Xonar STX as the default card.

On my machine I have the following in /etc/asound.conf

pcm.!default {
    type hw
    card XFi
}
ctl.!default {
    type hw           
    card XFi
}

Yeah that didn't work. I get a message about .asoundrc being old or corrupted so Alsamixer basically ignores it.

I had three sournd cards at one time and they changed too. One solution is to add to the file /etc/modprobe.d/sound.conf with;

options snd-hda-intel index=0

You'll just have to figure out which card uses which module and exchange snd-hda-intel with that. You can also add the code to modprobe.conf. Naturally you can have several soundcard modules with different indexes. index=0 will be the first card and so on ...

If one of those cards is on your motherboard you might be able to disable it in the bios which would save you some work.

Slightly differently to swanson, in /etc/modprobe.d/alsa.conf I have:

options snd slots=snd_emu10k1,snd_hda_intel

so snd_emu10k1 (my ancient SB Live) gets preference. Also snd_hda_intel (from nvidia gfx card) is blacklisted (/etc/modprobe.d/blacklist.conf) just to make sure.

Oh thanks for telling me about the index option. When I had this problem earlier I explicitly loaded the snd modules in rc.conf instead of relying on autodetection. That seemed to make the order the same every time.

I assume you changed the 'XFi' (my preferred sound card) to 'STX'
