Hi. I have Molnar's rt patch on 2.6.22.1, Debian testing. I have Jack 0.103.0and Csound 5.06 beta Aug 12 2007. I have added to /etc/security/limits.conf several lines for @audio, one of which is @audio - rtprio 99. User chuckk is in group audio. I added a line to /etc/pam.d/common-session: session required /lib/security/pam_limits.so. I can run jackd or csound or Pure Data and then use chrt -fp 70 `pidof "csound"` to set rt priority, but csound will not set priority itself from the sched=n flag, and jackd has the same problem. Can anyone tell me what might be wrong? Thanky. -Chuckk -- http://www.badmuthahubbard.com
