    Thanks. But the output after update (alsa-info.txt.bad) looks weird.
    It contains unexpected pin-update for NID 0x15 (found in
    /sys/class/sound/hwC0D0/driver_pin_configs), and thus the mixer
    elements created don't match with the results on HD-audio emulator.

    Could you double-check whether you have no modification over 2.6.38.4
    driver?
