You could select an audio profile from an IR remote. 

Thanks, switching profiles via the remote is working great!  I already add activities (on the remote) set up for movie watching and multi-ch music, so I just added the profile switch as an additional setup step (switching back to stereo music afterwards).

I think I'll go experiment with a USB-attached DAC some as well, given how easy your addon makes it to change profiles.  Thanks again!

(Would it be possible for auto-switching mode to switch back to the previous profile at the end of media playback?  This capability, unfortunately, wouldn't help with the stereo-vs-multi channel music setup, but it may be helpful in some scenarios.)
