[LAU] State of Edirol UA-101??

Hi, I got an Edirol UA-101 USB 2 card, which is a good value/quality multichannel card, thinking that it would be well linux supported. It seems that it's the only one from the Edirol line with some problems. Basically with Ubuntu 9.10 there was no support at all and only with the latest ALSA (and latest ubuntu 10.04) playback and recording is working. Recording is actually fine in all the channels etc. but playback is chopped and clicky. I found from some LAD posts about a year ago that it's a problem of the ALSA driver (or that they haven't managed to reverse engineer it properly as they have no official specs). Anybody knows anything about the current state of the driver or any fixes? I didn't manage to find anything more than that.. Cheers, polarch
