[mythtv-users] bt878 sound issue on Fedora Core 5

[Andrew Martin]

I just installed Fedora Core 5 and am having trouble getting sound on my 
Hauppauge WinTV (bt878) card to work. Video works fine, I just can't hear 
anything!   I previously ran Gentoo (2 years old) on this system and was 
able to get MythTV working fine.  Here are some of the detals:

- Audio works fine on the system otherwise (I can play mp3s, for instance).
- I’ve tried messing with all the sliders on alsamixer and kmix, to no 
avail.
- Tvtime also plays video, but no sound.
- I hear a ‘click’ when I start tvtime, as if the sound is about to start, 
but then I can’t hear anything.
- There are two sound cards on the system, but I'm not using the integrated 
one.
- I've tried the modifications to modprobe.conf described here:  
http://www.gossamer-threads.com/lists/mythtv/users/219519

Any ideas would be greatly appreciated.  Below is the output from lsmod, as 
well as the relevant content from dmesg and modprobe.conf
