Yes it would be nice to get jack working correctly with the quattro.

For reference I successfully recorded for a few hours using 4 channels 
of the quattro over nfs and had perfect sound quality and no dropouts 
with arecord.

One thing is that many people have reported getting very good results with

jackd -d alsa -d -r 48000 -p 480 -n 3 -d quattro1/2


I think your seeing strange results in non realtime mode for other 
reasons. Do you use jackstart as a normal user?

I always run my sound apps as root on this machine so haven't looked 
into non realtime mode.

Have you also tried using the only playback and only record options?

========================================


Apparently upon the beginning of the barrage, the donkey broke 
discipline and panicked, toppling the cart. At that point, the rockets 
disconnected from the timer, leaving them strewn around the street. 
Tethered to the now toppled cart, the donkey was unable to escape before 
the arrival of U.S. troops.
