Hi Peter.

Thanks for the suggestion.

For some reason the audacity.deb won't see my soundcard, so I compiled from 
source;  this version sees my card but won't play the generated tones.  I get 
clicks & pops when I try to play stuff. 
NOW, I think its my deb kernel 2.6.20-1 (kbuild) timer frequency which is set 
at 250 htz.   I think this, because rosegarden complains about the timer 
frequency being to low.
I would like to re-set the kernel timer frequency to the max - 1000 htz, but I 
need the boot - timer frequency boot parameter.

I would like to re-compile a kernel, but the latest kernels don't support my 
new Mboard (m2npv-vm).  This is why I'm running a kbuild kernel.

Is anyone familiar with a way of changing the kernel timer frequency via boot 
or a system call?

Thanks to all offering help on this.
