[mythtv-users] PVR-250 composite sound OK, No sound on tuner!

[Dave Pearson]

OK I've tried removing the lines form my modprobe.conf as suggested, but that 
had no effect (although I had to put some back to get any output from the 
card at all. I also checked to make sure that I only had the one msp3400.ko 
module. Unfortunately none of this seems to have worked - does anyone have 
any other ideas or, better still, a working modprobe.conf file from a 
Mandrake 10.1 system.

Regards,
Dave.
