Further testing against the tip does indeed break automute on my 5045
test board. I don't have any way of testing the 5047. I also looked
over the patch, along with the original file, and it appears to be an
older version of the driver. Current drivers don't have a "Master
Playback Volume" control of this type, as I replaced them with
bind_master_vol functions. What version are you testing?
This patch does not cleanly apply to the tip as it stands.
