You don't (and usually can't) set the sample rate of your soundcard.  
The programmer requests the rate that they want and the card usually 
gives it to them.  Sometimes if you have a digital receiver, then the 
output gets stuck at 48Khz because that's all the card designers felt 
like implementing for spdif.  Ocassionally (much more rare I think), the 
card gets locked in the same way at 44Khz.

Suprisingly, from the angle I am sitting here I can't quite see which 
sound card you even have....

It could be.  Try changing the refresh rate to 50Hz.  You will probably 
need to generate a new modeline (there is some X app that I forget the 
name of which does it automatically).

Try also checking your myth options in the tv playback settings menu.  
Stuff like "use video as timebase" is not going to work here.

Sounds wierd.  You really do need to try to provide more info to get 
this debugged though

Good luck
