[mythtv-users] No Audio on PVR-350 but available when 350 notselected

[Paul Fielding]

Hmmm.... I'm using KnoppMyth R5V22  (or do I have that backwards?), with updated ivtv drivers.   Didn't fix. :(  Still really choppy (like 2 frames/sec) with audio if I don't use the 350 Enabled settings,  Clean playback but no audio with the setting enabled.

I'm using a HushPC with it's built-in audio.  I'm starting to wonder the following:

- perhaps the audio out on the 350 isn't working properly at all, and when I have the 350 hardware playback disable the audio is being generated by the sound card?  But when enabling 350 playback the audio isn't leaving the card, therefore even though it's looped back to the sound card I'm not hearing anything?  (The audio out is looped through what I believe to be the line In on the motherboard)
- Perhaps I have the Line In on the motherboard all wrong?  Or is there a setting somewhere to check if it's enabled or not?  (though i've diddled in Linux for years, I've never really messed with audio, haven't needed it).

*sigh*

  Choppy video playback:

  I had this same problem - it was because XV wasnt enabled... and XV wasnt 
  enabled because I was using an old crappy firmware file, once i upgraded to 
  the new ivtv firmware, XV worked fine, then playback worked fine...   
  (without enabling the 350 TV-Out in the settings)
