Playback stops when audio changes from stereo to 5.1

[bacobart]

I don't know how useful this is to finding the problem, but I've tried the latest standalone omxplayer (git20130423) and the audio switch works without a hitch. Command line was "omxplayer -p -w -g Game.of.Thrones.S03E04.720p.HDTV.x264-EVOLVE.mkv" (so with hardware decoding and audio passthrough).

omxplayer even shows the audio channel change on console output: http://pastebin.com/FTpWz6m3

omxplayer.log: http://pastebin.com/jghis6n7

So it seems the problem lies with xbmc (or the version of omxplayer xbmc is using?)... Is there anything further I can do to help?
