[mythtv-users] Lost Sound on PVR-350 After Upgrade to IVTV 0.4.1

I had the same problem as you -- you can search the list for the
answer if you want more background. Here was the solution:

So far I've been using yum to update my drivers, vs compiling from
source. You are right though, I
did have the wrong msp3400 driver loaded. From the mythTv list the
following steps were
recommended, which worked fine:

Go into /lib/modules/$KVER/kernel/drivers/media/video and rename
msp3400.ko to msp3400.ko.orig
Next, go to /lib/modules/$KVER/updates/drivers/media/video and copy
msp3400-ivtv.ko to msp3400.ko
Run depmod -a

Now reload the module
modprobe -r ivtv
modprobe -r msp3400
