Comment(by stormshaker):

 I'm running 0.22-fixes (22764) on OSX 10.6.1. I have the same problem.
 After some testing though, it seems like it might be a problem on stopping
 playback rather than starting?

 My settings for Audio are the simplest I can make: CoreAudio, Passthrough:
 Default, Output channels 5.1, Passive Upmix, AC3 Passthrough on and SP/DIF
 passthrough on.

 When I playback a recording that contains digital audio, I see the
 receiver switch over to Dolby Digital and the playback is perfect. Then
 press ESC to stop playback and return to the GUI, the receiver is still
 receiving Dolby Digital output. Go back to the same recording and play it
 again, it plays much faster than normal speed. Quit Mythfrontend and
 return to the desktop - receiver is still stuck on Dolby Digital. Go back
 into Mythfrontend and play the recording again - it plays at normal speed.
 Back to the GUI then play again, fast speed.

 So it seems there's something left behind after the first playback of a
 recording with digital audio that affects subsequent playbacks. Restarting
 Mythfrontend is enough to clear it.

 OS X 10.6.2 is out, I will repeat the tests under 10.6.2 after upgrading.
