Also, you can replace the files in sound/pci/hda/* from 2.6.39 kernel tree. If this fixes the problem, it's a sound driver bug. If not, it's anything else, e.g. the problem in more core side, e.g. IOMMU like above or the timer change, etc.
Hey, that was a great idea! I reverse-patched sound/pci/hda of 3.0 with 2.6.39.3, and it fixes the problem! :)
OK, then try to replace only sound/pci/hda/hda_intel.c and keep the rest. What happens?
Doesn't work, that sound is choppy again.
OK, then keep hda_intel.c as 3.0 and replace the rest. If this works, please give alsa-info.sh output (run with --no-upload option).
thanks,
