Hello, I have no sound on my Sony Vaio SZ4XRN laptop with newest kernels. Sound: hda-intel, sigmatel - STAC9872

To solve this issue I make this patch for sound/pci/hda/patch_sigmatel.c:

Constants got from old kernel (2.6.22). With this patch sound works fine. Thank you.

Most of verbs above must be superfluous, but some of them might be needed in your case.  Could you give alsa-info.sh outputs (run with --no-upload option) on both working and non-working cases?

thanks,

Takashi

Yes of course, here is my alsa-info-nosound.txt on default kernel and alsa-info-work.txt with patch (see attach).

Thanks. Could you check whether the one-liner below fixes your problem?
