[mythtv-users] Unable to set ALSA parameters

[Sage]

I do have a basic .asoundrc file set up.  The contents were in my  
previous message.  It's worked for others so I don't know why it  
wouldn't work for me...  I'm not trying to do any sort of digital  
output or AC-3 passthrough or anything, just straight up analog out.   
Nonetheless, I tried the solutions put forth in that  
DigitalSoundHowTo with no luck.

However, after some fiddling I have noticed that this error does not  
occur if I don't try to play back through the PVR-350.  As soon as I  
start playing through the decoder, ALSA complains.

Also, if use the PVR-350 audio output only, then I get no sound,  
despite looping the audio directly into the sound card.
