Xruns are basically only bad if they happen while you're trying to do something interesting. I've never been able to eliminate them completely, but I can usually get my box settled down to where everything is behaving itself when I'm using it, and I only see these when JACK is basically idle. I tend to get xruns from other things, like the link phase of a Rosegarden build, for example, which might cause me 247 xruns in a row, but it's rare for me to get them at a cricital time in the middle of recording something. This is in stark contrast to the days when I was trying to run on a stock 2.4 kernel. I got a perpetual, nearly unbroken stream of xruns then, and JACK wasn't usable. > When I run jack I also find that I get a very high pitched frequency > sound coming from the computer.

I'm running a kernel I more or less ripped off from Studio..to Go!, actually. JACK is arcane rubber chicken goat blood voodoo stuff, and not my bailiwick. I suggest you try the broader Linux audio community for that stuff. -- Michael McIntyre ---- Silvan <[EMAIL PROTECTED]> Linux fanatic, and certified Geek; registered Linux user #243621 http://www.geocities.com/Paris/Rue/5407/ http://rosegarden.sourceforge.net/tutorial/ ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
