I have now! :o) But no, it doesn't make a difference. All that happens now is that JACK tries to start, and then stops, without the messages between. As I mentioned elsewhere in this thread, turning off the real-time option allows JACK to start. But I am seeing a lot of XRUNs, which I didn't see before. Previously, JACK would run RT-enabled, with only occasional XRUNs. My machine is a P3 700MHz box, with over 600Mb of RAM and an RME DIGI9636. It is running an up-to-date PlanetCCRMA FC3 distribution. I believe I am using fairly conservative settings for JACK: /usr/bin/jackd -v -R -dalsa -dhw:1,0 -r48000 -p512 -n2 Regards Michael
