snd-intel8x0: failing modprobe, no switch for pcm

hello!

i have a strange problem. often modprobing of the module snd-intel8x0 fails. when it fails i have no switch to toggle pcm on/off. of course sound doesn't work. i have to readd the modul until i can toggle pcm.

here are some information:

$lspci
...
00:1f.5 Multimedia audio controller: Intel Corp. 82801DB AC'97 Audio (rev 03)
...

$lsmod | grep snd
snd_intel8x0           30528  0 
snd_ac97_codec         85116  1 snd_intel8x0
snd_pcm_oss            51104  0 
snd_mixer_oss          18432  1 snd_pcm_oss
snd_pcm                84868  3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer              22660  1 snd_pcm
snd                    49380  6 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore               8032  1 snd
snd_page_alloc          8840  2 snd_intel8x0,snd_pcm

$amixer set PCM on
amixer: Unknown playback setup 'on'..

i'm using the newest current arch stock kernel and the newest current alsa-packages.
thx for any solution of this problem

bye iggy

Re: snd-intel8x0: failing modprobe, no switch for pcm

erm try setting a volume level..

amixer pcm 95

I have the same card, too be honest there has been no issues for the last three kernel versions even dmix works out of the box

try running alsaconf
if its a laptop check for a simular module name with an m on the and and blacklist it if conflicts

Re: snd-intel8x0: failing modprobe, no switch for pcm

alsaconf is done. no snd-intel8x0 module loaded. can set volume to pcm, but cannot toggle to on, that means - no sound! can i add some arguments to modprobe.conf or something other?

Re: snd-intel8x0: failing modprobe, no switch for pcm

here's what I have in my modprobe.conf:

install snd-pcm modprobe -i snd-pcm ; modprobe snd-pcm-oss ; true
install snd-seq modprobe -i snd-seq ; modprobe snd-seq-oss ; true

Can you add some kernel.log output about loading the module? See any difference there between the failed and working attempts? I have a

[thomas@architect ~]$ lspci|grep Multimedia
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS7012 PCI Audio Accelerator (rev a0)

which also uses snd-intel8x0, no problems here so far. (But - I use my own custom kernel, don't think that makes any difference).

This is what my kernel.log says when loading the module:

Nov 21 10:07:26 architect intel8x0_measure_ac97_clock: measured 50981 usecs
Nov 21 10:07:26 architect intel8x0: clocking to 48000
