Excessive CPU usage?

Subject: Excessive CPU usage?

Ok, trying to narrow down why my app takes 5% CPU (Debug), I eliminated everything in the IOProc
callback. No change. With my application doing absolutely nothing, it still takes 5% CPU with
most time in CoreAudio (time profiler show iokit_user_client_trap on top)

Any ideas ?
TIA
/Rob
