Could you run alsa-info.sh with --no-upload option and attach the
output for both states with and without that commit?  The script is
found at
	http://www.alsa-project.org/alsa-info.sh
Also, show the relevant kernel message from snd-hda-intel (informing
the auto-parsing of pins, etc), too.

Takashi
