OK, then could you give alsa-info.sh outputs (run with --no-upload)
at docked (non-working) and undocked (working) states with model=auto?
If the dock-output works with your patch, give alsa-info.sh output
at that state, too, for comparison.

The alsa-info.sh output is the best material to track down a HD-audio
issue, since I can run an emulator here with it.
