Strange, after a clean install of 64studio testing jack doesn't work anymore: These are the messages which I get: 14:34:53.317 Patchbay deactivated. 14:34:53.378 Statistics reset. 14:34:53.464 MIDI connection graph change.

disable «Realtime», remove the -R parameter in /usr/bin/jackd or run as root.

Sorry, I think a messed up

Sorry, I think I "messed up" 64studio a bit. Did a clean install and shift to Testing, and thought I installed also the new kernel from 64studio, but there's no multimedia in the kernel's name... :/ ;) So I'm wondering if there is a different kernel in testing compared to stable and if 64studio testing is compatible with Debian testing. Than I will install a new multimedia-kernel and rebuild my nvidia module... http://www.64studio.com/node/372

Try increasing frames/period

What audio card are you using? Report the output of "cat /proc/asound/cards" Anyway, if you are using your onboard audio card I think 64 frames/period is not a good option. Increase that value until you have jack running stably with no x-runs (red numbers). You had 256 before, as you showed in a screenshot in http://www.64studio.com/node/321. You might be asking too much to your audio card, that's why JACK crashes. Other possible reason is the priority. The message says something about it. I am not sure what it really means that but try increasing that value too. Pablo
