[mythtv-users] Occasionally HD program plays without sound: NVP(0): Disabling Audio

[Gareth Glaccum]

Sorry, can't see the original post at the moment, so could be wildly off. One 
thought though, 

sometimes my system records HD, and there is no sound played by myth
This is because the HD program appeared to have been broadcast/flagged with the 
sound channels the wrong way around.
i.e., it does play the sound, but it is playing the audio descriptive sound, 
which is often pretty blank. 

Pressing the - key on the keypad swaps the audio channel selected, and the real 
voices come back in
(just a thought, and similar warning messages I think when I originally tried to 
diagnose the problem)

Ok, thanks. Interesting that mplayer doesn't seem to care.

I take it there is a flag to ffmpeg to tell it to ignore that error and play
sound anyway, and that flag would have to be set in mythfrontend code?

Thanks,
Marc
