I inherited a Hauppauge WinTV-GO (BT878) pci card. I installed in my RH9 2.4.20-20.9. It has a Nvidia TNT2 using the "nvidia" driver.
I can get both xawtv and tvtime to display, but no sound. My cmpci sound card works fine. For example, mplayer plays videos with sound just fine.
Not sure where to start in tracking down the problem.
