Ok so I have my AVERTV M150-D TV Tuner working on the computer, however sound is screwed up, its really deep when people are talking.

I'm following instructions from here:
I can't post urls so google mythtv AVERTV M150-D; first result should be a mythtv wiki page.

It suggests using a script similar to:
/usr/bin/v4lctl -c /dev/video2 setchannel $1
/usr/bin/v4lctl -c /dev/video2 volume mute off
/usr/bin/v4lctl -c /dev/video2 setfreqtab us-cable
/usr/bin/v4lctl -c /dev/video2 setnorm NTSC-M
sleep 1
(I have tried the same one he uses as well)

And find that it does not change channels and goes all fuzzy, sound fuzzy as well.

On this box, I also have a Hauppauge card, when I try to use v4lctl to change the channels on that card, I get the same result. So I think, its got to be something wrong with v4lctl.

Also, if you can think of another way to solve this issue, that would be awesome too.

I don't know what to do, any help is REALLY appreciated!
