 Hello,

 for since about 2-3 months ago I have been experiencing problems with
 Mythtv recordings from one particular source (YLE Finland), don't know if
 this is a more common issue. It seems AFD fails to find correct audio
 format or audio channels altogether which results in no audio at all. The
 audio is fine if I play the same recording with ffplay.

 Sometimes audio is recognized as MP3 (while it is MPEG2). If I fast-
 forward couple of minutes, set a bookmark, and start play again, audio
 tracks are occasionally recognized correctly.

 I can submit a .ts sample if needed.

 When it's working its like this in log:

 from start)

 All the other channels play the audio just fine.
