It's a laptop. There's no sound, not from internal speakers, not from headphone out. There is a mild crackling sound when the module is loaded, but that's it. The patch does not change things.
OK, I'll send another patch tomorrow. But the previous patch should work, still. Make sure that you adjusted and unmuted the mixer elements after applying the patch. There should be some new mixer elements.
If it still doesn't work after the mixer adjustment, give alsa-info.sh output again.
Also, there are many bogus input pins on your device. Which physical inputs are on the machine? BIOS advertises that there are front-mic, rear-mic, line-in, aux-in and CD. Do all these work properly? You can choose it from "Input Source" mixer enum.
Also, it also advertises SPDIF input and output. Are really both on your machine?
The only physical input is mic-in. But there's also an integrated microphone. In kernel 3.3 the intergrated mic is simply "Mic" and works for both playback and capture. I don't have an external mic to test.
In kernel 3.4 I still don't have sound, even with the patch (I unmuted everything there was to unmute, then muted SPDIF, nothing produced sound), so I could only test capture - "Rear Mic" captures from the integrated microphone.
I assume "Front Mic" would work for an external microphone, and maybe CD is for listening to audio CDs? The CD drive broke a few years back, so I can't test it.
No idea about SPDIF-in, but headphone-out doubles as SPDIF-out. There's a red light inside the jack, and if I unmute SPDIF, the light goes on. I remember it was like that also in Windows. I don't have appropriate hardware to test if it actually works.
Attached is a alsa-info.txt with the patch. There are some differences compared to without patch, but like I said above, still no sound.
