[mythtv-users] Help - no sound on some channels (bttv) after kernel & module upgrade

[Joseph A. Caputo]

Last week I upgraded my FC3 box to kernel 2.6.12 & ivtv 0.4.2 (I've got 
both an ivtv and a bttv card in the box).  After some struggling with 
module aliases & options to get the new ivtv working (I was upgrading 
from 0.2.x), I got my M-179 working again flawlessly.  However, now I 
have no sound on 3 or 4 channels on my bttv card.  Unfortunately, one 
of those channels happens to be SciFi!!!

I also see a lot of the following messages in my system log:

ALSA /var/tmp/bach-build/BUILD/alsa-driver-1.0.10/pci/bt87x.c:286: FIFO 
overrun, status 0xe8005008

which may or may not be related.  I made sure I updated my ALSA 
driver/modules & libraries to the same version, and yes, I am using 
snd-bt87x to capture the audio for my bttv card.

I'm pretty sure I don't need to fine-tune the channels, as the M-179 
tunes them just fine using the same video source, and even the WinTV 
card was tuning them fine until this upgrade.

Any thoughts?  I've seen some threads where people lost sound on some 
channels after upgraded to ivtv-0.4.2, but they were all using the ivtv 
card.  I'm seeing this on the bttv card, which I find weird.

Thanks,
