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?
