Comment (by Nicolas Pöhlmann <nicolas.poehlmann@…>):

 After another debugging session I've found the error which caused the
 missing audio for me.

 It was a simple audio timecode error while transcoding to mpeg4+mp3. The
 last written timecode was set only to the new (encoded) frame timecode
 instead of setting it to the offset timecode where the audio frame in the
 file to transcode begins. So mythtranscode could just not simply find any
 audio frames with a valid timecode because it search for (0+x) instead of
 (y+x) and just set audio each audio frame output to null.

 I've also changed the position of all audio output transcodes to be writen
 after the video output because it always references the video frames
 timecode. Maybe this can fix the problem where audio begins to late in a
 video.
