[ubuntu-mythtv] no TV sound

[Marty]

I just setup mythbuntu 9.10 with a pinnacle pctv card that I have set up as an analog capture card.  The picture on a monitor is ok but I have no sound when I watch TV.  My sound card is a SB Audigy and sounds fine when I stream radio.  

I have my sound card wired with a Y cable/RCA cable to my amplifier/speakers.  I went in alsa mixer as my user and as root and all looks ok in both the sound card settings and the capture card's audio settings.

Any ideas how I can get sound on my TV?
