[mythtv-users] ivtv + bttv - no sound from second tuner

[Brent Fisher]

I know that similar topics have been posted in the past but they haven't 
helped me to solve  my problem.

I've had a MythTV box running for about a year and a half with a PVR-250 
and it works great.

Recently, I purchased a cheap WinTV GO FM to use as a second tuner.  
This card has no built in sound chip - it just has a line-out that I 
have plugged into the line-in on my NForce motherboard.

The problem I'm having is that I can't get any sound out of this second 
tuner.  The card installs correctly, I get video and it is outputting 
sound but I can't seem to get Myth to pick it up.

Both cards are set to use audiodevice=/dev/dsp and I suspect that herein 
lies the problem, but I don't know what to do about it.  Only recordings 
from the PVR-250 have sound.  There is no other /dev/dsp* files.

Does anyone have any hints?  Is there more information I should provide?

Thanks in advance,
Brent
