 One of my ten channels has no audio stream (recordings and liveTV).

 When I try to watch the problem station using myth, the backend complains:
 {{{
 2007-02-24 00:43:23.380 Started PESPacket, but !payloadStart()
 2007-02-24 00:43:23.410 Started PESPacket, but !payloadStart()
 2007-02-24 00:43:23.453 Started PESPacket, but !payloadStart()
 }}}

 This is a section from my frontend log when attempting to watch the
 station in liveTV:

 }}}

 By trial and error I determined that:
 {{{
 Using revision 12438 and watching LiveTV tuned to channel 7.1 the audio
 works!
 Using revision 12439 and watching LiveTV tuned to channel 7.1 and the
 audio is broken.
 }}}

 '''Example stream from broken channel here:

 Using azap and mplayer to play the station works fine.
