[mythtv-users] cx88x audio problems

[Jim Peters]

Hello Mythtv-users

I have a KWorld Hardware Mpeg TV Expert card with the blackbird chip, 
and a TNJ 7751MMF tuner. Mythtv doesn't automatically find it but I used 
the modprobe option "card=45" then after some googling I decided the 
tuner was a MK3 type so I also used the "tuner=43" option. I did have to 
input the device (/dev/video1) in the mpeg encoder card setup screen in 
order for mythtv to show it as the probed card, but it seems to work, I 
can tune all my analog channels and it has a very good picture, but the 
audio sounds like an old vinyl record when you slow it down, women sound 
like men and men sound like demons from a low budget thriller. This 
happens in both recordings and live TV, I don't see any audio settings 
in mythtv like there is for the software encoder cards and i assume this 
is because the audio is encoded along with the video as part of the mpeg 
stream. What can I do to fix this?
Here are the pertinent lines from dmesg:
