Thanks. Going through the vendor verbs revealed the issue. Multichannel mode
was getting reset on suspend, and was not properly reinitialised by the driver
on resume.

Will prepare a patch for the ALSA folks. I guess you can close this bug entry
as invalid.

AFAIK, video driver doesn't have anything to do with the mappings.  Does
forcing a modeset after resume help?  E.g., change the mode with xrandr and see
if that helps.  Maybe some of the AMD specific verbs in the hda driver need to
be reset?
