Switching tabs in my window manager (ion3) causes artefacts in phasex sound. I run jack2 in realtime mode, dsp load is about 15%. I run a 2.6.23.1-rt11 kernel. I run the opensource radeon driver. My audiocard and rtc IRQ threads run at higher priority than JACK (82 and 98). JACK runs at priority 80. # ps -eLo rtprio,pid,spid,class,args |sort -rn|head -n 20 99 4 4 FF [posix_cpu_timer] 99 3 3 FF [migration/0] 98 845 845 FF [IRQ-8] 97 5 5 FF [softirq-high/0] 82 1232 1232 FF [IRQ-20] 80 12779 22340 RR /usr/bin/jackdbus auto 80 12779 22338 RR /usr/bin/jackdbus auto 80 12779 22337 RR /usr/bin/jackdbus auto 77 22421 22424 FF phasex-01 75 22421 22427 RR phasex-01 75 22342 22355 RR /usr/bin/a2jmidid dbus 50 9 9 FF [softirq-block/0] 50 989 989 FF [IRQ-17] 50 921 921 FF [IRQ-16] 50 8 8 FF [softirq-net-rx/] 50 854 854 FF [IRQ-15] 50 851 851 FF [IRQ-14] 50 80 80 FF [IRQ-9] 50 7 7 FF [softirq-net-tx/] 50 6 6 FF [softirq-timer/0] -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>
