I have a device template for Denon Receivers that I have tweaked that is an improvement (at least on my system) over the stock one that came with snapshot 23359. The shortcoming in the stock template is that it allows extraneous switch input commands to reach the receiver which causes audio to cut-out for several seconds when starting playback of media.
The template I am referring to is AVC-A1SRA (RS232) #71. Thom and Andrew mentioned recent work on that template here (but sadly it didn't fix this problem as was hoped): http://forum.linuxmce.org/index.php?topic=7393.msg51364#msg51364.
A detailed description of the problem and solution are detailed in my two posts here:
The problem and solution are well understood and I'd like to get this fix into the mainstream code so we don't have to tweak this template manually on each new installation.
