You'll probably have to crank the period size up until the xruns stop then work with that. Do any of the Linux audio oriented distros come on a live CD? Lee

Tried ArtistX, Ubuntu Studio, JAD, and Musix too, and just upgraded to Parallels 4.0 with significant improvement in functionality and performance, but that was after setting up Fedora 10 and deleting the others so I don't know if any of them would leapfrog and wind up in a better position than they occupied under Parallels 3.0. Anyway, if any MacBook or other OS X user has found an optimal configuration for running Linux audio in a Parallels VM (and I know that's not how you'd do critical audio work), I'd appreciate any tips you might pass my way. Currently, I'm using built-in input and output set in OS X's preferences and for the VM, and in jack 1024 frames/period with 4 periods/buffer in RT. Folks at this WNYLUG (wnylug.org <http://wnylug.org>) here in Western New York are quite interested in virtualization technology as well as audio work so I'd like to be able to give them a good look at both. I'd go a little further than Lee did. This is a *crazy* way to demo "linux audio" to anyone. Either demo JACK to them, natively on OS X, or demo Linux & JACK. Nobody who actually cares about this stuff is going to run in a VM, so the demo is pretty meaningless in terms of showing people "what can be done". (current) VM's are great for software that isn't locked into an intimate relationship with actual hardware. its far from clear when (if ever) they will be suitable for something like JACK which locked into a very intimate relationship with the audio h/w.
