Some more info...
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.
