I use is regularly for DJing, although only with 2 channels. I used it 
yesterday for recording with ardour and the sound was pretty crap. I 
have at various times got excellent quality out of it though, it was 
through the direct alsa layer.

I haven't tried it with latest jack and all the i/o options. If you have 
the time it would be nice to hear how the latest code is working. You 
should make sure you are using at least:

latest 2.6.x
latest cvs alsa drivers
latest cvs jack

Otherwise I will probably give it a run in the next few weeks ;)

You could always use it only with the alsa native drivers

arecord -f 24_3le -r 96000 -c 2 -D quattro1 -d 5 test.wav

will record a five second test at the highest quality available on the 
first two channels.

I haven't had much luck using it with jack for recording. Last time I 
tried it didn't work well enough for 4 channels and the 24 bit support 
doesn't register for me (although it did for at least one other person).

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


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.
