[SOLVED] ALSA (no pulseaudio) - sound card order changes on boot

Hi,

reading https://wiki.archlinux.org/index.php/Ad … le_options
I try to prevent random "card" index changes at boot. Arch wiki says to use

$ cat /proc/asound/modules

to get the loaded sound modules and their order, then disable modules that we do not use to prevent their use.

However on my system I get two snd_hda_intel :

 0 snd_hda_intel
 1 snd_hda_intel
 2 snd_usb_audio

Yesterday I get

 0 snd_hda_intel 
 1 snd_usb_audio
 2 snd_hda_intel

I already tried two disable snd_usb_audio, however I can't disable snd_hda_intel as it would disable both (disabling is done with module name).

I run out of ideas, it is very frustrating. I try to "resist" installing pulseaudio, however if I can't solve this issue I afraid I have to

If the fix in the Release Notes doesn't work, you might try an .asoundrc configuration.

If you have 2 cards sharing the same module, use the enable option. See :-

Do you mean Beowulf release notes? I read it again, it is a fix about PulseAudio.

I already use .asoundrc with

defaults.pcm.card 0  
defaults.ctl.card 0

The problem is the card number 0 that change to 1 or 2.
