[mythtv-users] No sound from WinTV in FC5

Good morning, all.  I'm still fighting my upgrade to FC5, and am out of 
ideas again.

mythtv and tvtime both have sound when I boot into FC4, but not when I 
boot into FC5 (separate drives on the same box, my FC4 drive is dying, 
and FC5 is a fresh install on a new drive).  "aplay" does produce sound, 
along with everything else I've tried besides mythtv and tvtime.  I 
think I've narrowed it down to the actual output from the WinTV card (as 
opposed to the sound card) - when I plug speakers into the WinTV card 
output, I get sound in FC4, and none in FC5.

My WinTV card says, "model 400" on the box.

I've uninstalled ivtv (I think it's not for my WinTV card).  I have all 
yum updates up-to-date, except for the kernel (I'm running 
2.6.17-1.2157_FC5).  mythtv is version 0.19, release 130.fc5.at.

The following lsmod seems relevant, but it's over my head:

The same goes for a dmesg output:

[root at dave ~]# dmesg | grep bt

Does anyone have any more ideas?
