What is odd about this is that the noise only comes from the internal 
i/o. If I play through an external and use the direct monitor switch the 
  sound is perfect.

I get the most stable jack with these settings:

- using the hw layer.

jackd -v -R -d alsa -d quattro2 -p 4608

- using the plug layer.

jackd -v -R -d alsa -d q4 -p 1017

I have tested (using ardour) a 48khz stereo sine wave. For the first 
example I get white noise and for the second I get an almost clean 
signal which sounds slightly higher pitched than it should.

Note that using the previous version of the driver I could get a clean 
signal from all native alsa apps.
