sound card disappears every time I reboot
Last modified: 2006-01-03 09:54:47 UTC
No matter which of my 3 computers I use, everytime I reboot, the sound card disappears. That means, there is no sound till I go into yast2, delete my soundcard, and add it again.
Check /etc/sysconfig/hardware/hwcfg-* file whether any of them contains the corresponding sound driver module. If not, the yast configuration didn't work by any reason.
Also, check the mixer status when it happens. Some volumes might be muted acciedentally by apps.

You can run "grep snd /etc/sysconfig/hardware/hwcfg-*".
kolossus:~ # grep snd /etc/sysconfig/hardware/hwcfg-* kolossus:~ # yast2 sound kolossus:~ # grep snd /etc/sysconfig/hardware/hwcfg-* kolossus:~ # before the yast2 sound, sound did not work, after it, it worked. So, the only difference between working sound and non-working sound are the loaded drivers.

Yast loads the modules, but hwcfg file is still missing when configuration is finished... Please, attach y2log (http://www.opensuse.org/Bug_Reporting_FAQ#YaST)
Created attachment 57294 [details] reconfigured sound, then drew the log
I have this problem on my Acer TravelMate 803 also (module snd_intel8x0). (If you need logs from me, just ask.)
hackish solution for me is to create a file /etc/init.d/after.local like the following: scorpio:~ # cat /etc/init.d/after.local modprobe snd_pcm_oss modprobe snd_mixer_oss modprobe snd_seq modprobe snd_seq_device modprobe snd_intel8x0 modprobe snd_ac97_codec modprobe snd_ac97_bus modprobe snd_pcm modprobe snd_timer modprobe snd modprobe snd_page_alloc modprobe soundcore scorpio:~ # Christian, please see my comment 3 to find out which modules you need.
/etc/init.d/alsasound reads /etc/modprobe.d/sound and loads the drivers (line 103) if they are in the typical alias-form (line 83). Problem is, /etc/modprobe.de/sound only contains one module after calling yast2 sound.
Oh, it seems that this is duplicate of #116483. Please, remove the card, save the setup (finish the yast module). Then start the module again and configure the card. Does solve your problem?
(In reply to comment #10) > Christian, please see my comment 3 to find out which modules you need. echo 'a3998fa3f22d990966baaaca5c646470 /etc/SuSE-release' |md5sum -c \ && modprobe snd-intel8x0 in boot.local is enough for my system - it also loads the other listed modules. Why I call md5sum before? I want to automatically re-test when upgrading to 10.1 beta ;-)
Ladislav, yes, it solves my problem - now I know how I solved this problem for SUSE 9.3!
