That isn't good.  Default automatically runs the sound through dmix.  
And it has a set frame rate of
48000.  Other rates are software resampled.  I want to avoid that and 
only use the hardware sample rates
so that there is no resampling on the sound. 

Is there a way to configure sound with pulse audio to avoid this, or do 
I have to remove pulse audio in order to
get direct access to alsa?

Thanks.
