[feisty] another issue with no sound after 2007-03-16 updates

Probably fixed in -12 kernel. Please retest, and mark "Fix Released" if things are now working.

I tried the -12 kernel. No different than the -11 kernel as far as my sound is concerned.

My guess is that since the -11 kernel, the audio driver has been identified more accurately. The no sound coming out problem may be an ALSA issue. I have found stories similar to this in which people had to mute certain channels; but they have different hardware. In the -9 kernel, the system uses a different ALSA driver with fewer mixer channels but the sound works.

I found a workaround here:

gnuboi - Was your issue resolved with a newer kernel at all?

Yes! I have 2.6.20-16-29 installed.

Originally I had to add "options snd-hda-intel model=3stack" to my
/etc/modprobe.d/alsa-base file. I commented it out and the sound
still works! The newer kernel must have fixed the problem.

Hi,

I have a DELL XPS m1210, and installed the latest gutsy release with all the latest updates. My sound didn't work, the snd_hda_intel module was loaded, but it was aparently unused and alsamixer (or gnome-volume-control) seemed not to detect it at all (it was not even on the list).

Adding snd-hda-intel model=3stack to alsa-base does indeed fix the problem, but this patch needs to go upstream.

Regards,

Careful with the "model=" fix. On a Kubuntu 7.04 installation on a Toshiba Satellite A200-14e, using model=3stack resulted in a loud screeching sound in the speakers as soon as mixer levels were restored, and the bootup would freeze soon after.

Unfortunately this was part of a remote walkthrough and I have no further data that would help determine the proper model= value that should've been used. The owner reinstalled with 7.10 soon after.

So this is basically a heads up. Be careful when using obscure kernel module parameters on moody hardware such as laptops.
