[LAU] Hello and configuring audio

Hi there, I guess I'll first start with a little introduction... My name is Marc and I'm developping a small tracker targetted to the GP2x. It's based the interface of a very well known gameboy tracker (littlesounddj) and it runs quite well on a small machine like that. For ease of development, demo or if people also desire to make it their platform of choice, the tracker is also available for Windows, Mac and I decently got a debian build working. I'm writing because recently I received for Xmas an azus EEE. Not a very powerful machine but a great little traveller for internet, coding and possibly... audio. I got my tracker running on it without to much trouble (which was to be expected since it runs fine using only one of the GP2x proc at 200Mhz) but I face a glitching issue on my EEE. First I thought it was due to the usual buffer configuration problems but then I realized both VLC and Audacity glitched too on playback. It's not a constant one.. more like here and there the audio device gets stuck (or some process/IRQ taking over?). It's kind of ennoying... I still have the possibility to install XP on it, but I quite like the Xandros install and would like to know if there's any way for me to troubleshoot/configure the installation to provide smoother audio out. I've tried using an external usb audio interface and noticed the same glitches. Any advices from the gurus ? Thanks Marc
