I have a similar problem, this is my audio card:

my problem seems similar to this:

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/107821

for windows toshiba release realtek audio drivers so maybe the realtek patch can solve this,

thanks

status on .21 kernel? it contains the latest alsa hg snapshot from 070427

same on .21 kernel, I installed the following package from testing:

alsa-lib-1.0.14rc3-2 alsa-utils-1.0.14rc2-2 ipw3945-1.2.0-6 kernel26-2.6.21.1-5 madwifi-0.9.3-4 nvidia-1.0.9755-5 slmodem-2.9.11-25

and still no sounds, additionally I have only a PCM channel no MASTER

on ubuntu the sounds works, can you grab the patch from there?

Solution found, for my card I have to add the following to modprobe.conf

options snd-hda-intel model=3stack

If you need additional info ask me,

thanks
Nicola

could you others please also confirm this fix?

works for me with the lastest stock kernel thanx a lot

Awesome, that fix worked here too.

OK, so this report can be closed, I think.
But we should made users aware of that workaround.
I propose the following: in kernel's post_install add that line (commented, of course) to modprobe.conf, in the same way as this is done to ld.so.conf.

closing this now, its not worth modifying modprobe.conf its now mentioned on frontpage.
It's an error in autodetection of the module, which will hopefully fixed soon by alsa upstream
