That makes sense, but I seem to be having trouble getting JACK to run at anything above 48KHz. When I start it at 88.2KHz or 96KHz, I immediately get messages such as "XRUN callback (xx skipped)", where xx is a number between 50 and 300, depending on which sample rate and frames/period I choose. I get at least 50 skipped callbacks per second without doing anything but starting jackd. If I am not mistaken, the Delta 44 should be able to handle at least up to 96KHz. I believe my kernel is set up properly since I can record 6 or 7 tracks at 48KHz and 512 frames/period in RT mode for an extended period of time without any xruns at all. Any suggestions? Alan
