    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
