Could you check whether reverting hda_intel.c to 3.2 fixes the
problem?  If not, try to revert all files in sound/pci/hda/*.[ch]
to3.2, i.e. for checking whether it's a regression in hd-audio driver
or somewhere else.

Also, please give alsa-info.sh output (run with --no-upload option) on
3.2.x kernel.  This will give more comprehensive information.


thanks,

Takashi
