The codec communication looks a bit unstable on this device... Does this still happen on the latest 2.6.30 version?
Yes, at least with 2.6.30-rc3. I reloaded snd-hda-intel a few times, and at some point /etc/init.d/alsa-utils start complained, I guess because some index numbers in the mixer changed.
And this happens because the codec doesn't respond properly any more. So, something triggers to screw up the communication with the codec. I have no idea right now. Possibly you can bisect the changes against sound/pci/hda/patch_sigmatel.c...
The problem is that I don't have a reliable way to trigger this bug. It just happens sometimes.
I just saw another, major problem: line in doesn't work anymore with 2.6.29 and also 2.6.30-rc3 (no usable input level). It works with 2.6.27.20.
So it seems that all newer kernels are pretty broken on this hardware regarding sound.
