Hi Alex,
I finally buy an Edirol UA25. It seems to be similar in term of feature,
and i have read this type of card was well supported, unfortunately i am
facing some issue. However i can use it for my purpose, except for one
thing: i get jack/ardour/jamin crash when putting jamin as insert on
master track. This is under investigation....
i just tried to play a sample (44.1kHz, 16bit, stereo)
and to record the
output of the sound card (by wiring its "line-out" to its "line-in").
On a
pentium 200Mhz running openbsd (sorry couldn't get to work my crappy
software on linux) the shift between playback and record is 6ms. this is the
time that the sound takes to propagate 2 meters. While this is enough for
me, i think that the shift will be much smaller on linux, especialy on a
better hardware/software.
How do you measure this delay? Are you using special software?
I am interesting to know the delay i have with my HW. (recent but
"cheap" laptop)
Do you know if it is an USB1 or USB2 compliant
device?
it is USB1.1 compliant; there is no proprietary and/or hidden features,
(even the direct monitor is compliant).
Last thing, what kernel and Alsa version are you using?
For now, i'm running 2.6.8 with Alsa 1.0.4. I hope i will not have to
update one of them.

i'm using linux v. 2.8.6 and alsa v. 1.0.4. (debian sarge)
Still with linux 2.6.8 but i have updated alsa to 1.0.10 (to get my UA25
working), i have also already updated ardour, jamin and jack (but have
switched back to original jack since i cant get it working).
Do you use these packages from debian, demudi or from manual install?

Christian
