Comment(by anonymous):

 I have been having some audio issues since updating to this revision.
 When transitioning from a commercial with non Dolby Digital sound back to
 a program with Dolby Digital I start getting "WriteAudio: buffer underrun"
 errors, the video becomes jerky and sped up and there is no sound.  The
 frontend eventually crashes.  In one instance I had "AudioOutput Error:
 snd_pcm_open(iec958): Device or resource busy" followed by "DEnc, Error:
 Could not open codec, invalid bitrate or samplerate" and then a frontend
 crash.

 If the video transitions back to non Dolby Digital before the crash, the
 non Digital audio works and the video returns to normal.

 I have configured my speaker configuration to 5.1 and have passthrough
 enabled.  I am not using time stretch.

 I actually prefer not upmixing the sound and don't want volume control in
 Myth.  It would be nice to have an option to only upmix/remix the sound
 when time stretch is used and doing so is necessary.
