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... > Attached is an example diff. This diff looks OK. The difference is just the current PCM stream you are playing.
