So I went out and got one Edirol UA-25, and I definitely have fewer problems than with the builtin soundcard. On my debian - sid installation it worked straight out of the box for playback (havent' tried capture yet)
There's some remaining issues when using JACK with pd, it sometimes causes a timeout and then JACK gets mangled and does not recover; increasing the frames/buffer so far seems to solves it at an acceptable latency level for me, however. It does not seem to require 3 periods setting though I have not accumulated enough evidence to know if the time-out occurs more or less easily with different settings like that. I beilieve this is completely unrelated to which soundcard is used.
Whereas the other probems I had , continuios clicks no matter what settings, are gone when using the UA-25 (and supposedly the sound quality shoudl be better though I have not compared objectively).

I also used to get subtle but audible pops every 30 sec or so using jack, and I never figured out why... maybe it's gone now ;-)
Interesting, that's kind of like what I was getting, I thought it was due to the Intel soundchip driver not-quite-there problem.
priority 89, frames/period 256, rate 48k, periods/buffer=3
I had to do periods/buffer=3 to get anythign to work without constant xrns with this intel. I'm surprised it's needed with the Edirol, or is it somehow to do with PD? Not that I know what 'periods/buffer' actually does...
