Comment (by jyavenard):

 This is the output playing file 2269_20110910180000.mpg.

 Note how AC3 is for me detected as 2 channels, and immediately after as 6
 channels (so it does passthrough). Activating timestretch and it goes back
 to being 2 channels audio. Something is wrong in AVD determining the
 number of audio channels of the stream.
 The file plays fine for me however, though without timestretch, as it's
 seen as 6 channels AC3 by default upmixing isn't active.

 I have noticed once that it keeps pausing/resuming audio. Pause/Resume is
 sent from AVFD/MythPlayer, someone needs to check why those are happening.
 Nothing to do with the audio framework.
