I’m pretty sure this was working under 1.3, but I rebuilt my configuration from scratch under 1.4, so I can’t be sure.
I have an activity for XBMC. I have it set to use the Denon receiver for volume control. In the volume display, Roomie alternates between two values: the actual volume setting and another value that depends on the XBMC volume. If I use the volume up/down buttons, they work fine.
I tried changing the ‘Volume Control’ setting for the activity to something else and then back to the Denon receiver, but that didn’t fix the problem.
