Aplay plays a wav just fine, so does XMMS with stream or CD.

QJACKQTL will run in playback or capture with only a few xruns, but duplex 
makes them go until this comes up: 
jackd watchdog: timeout - killing jackd
zombified - calling shutdown handler
cannot send request type 7 to server
cannot read result for request type 7 from server (Broken pipe)

I have an i810, and duplex should work with this and ALSA.  Frenando, 
you've been of great help and patience, if the answer isn't obvious to 
you, I may as well get a good card anyway right?

thanks for your help,
