Are you capturing via the tuner or via composite or s-video?
Basically the latter two need the sound to be fed in via a mic input on
the PVRs (I guess you're doing this since the sound usedto work)
If it's a seperate feed - can you feed this into an amp and ensure sound
is getting to PVRs.
Asuming it is working...
test_ioctl -v input=1,output=1
(try various values for input and output)

>Hey I remembered to change the subject this time! The situation hasn't changed. I can cat /dev/video or video1 (2 tuners) and I capture video but no audio. I copied the files to a windows box and I don't have any sound in media player either. I can still play MP3s perfectly with mplayer. I've checked the msp3400 file via the instructions in the Mythtv HowTo and it seems to be using the correct version. alsamixer has master maxed out, pcm set to capture and maxed out. I've tried muting/capturing all of other options but nothing changes. I keep thinking I must have messed up the msp3400 somehow. I DID copy the ivtv version of the msp3400 and did a depmod but that didn't help either. I've moved the Myth box back to the basement so that I stop annoying my family. I have it hooked up to a monitor and pc speakers now. All of the output volumes are maxed. It initially took me over a month to get this working right (I knew I shouldn't have recompiled the kernel) but keep being drawn like a moth to the standard windows solution... reformat-reinstall
