Is it normal that the pulseaudio process has sometimes a CPU usage of ~40%, even without playing audio? The process seems to run in realtime-priority, is that the cause of the problem?

Update: I deactivated the realtime-scheduling in /etc/pulse/daemon.conf and set the nice-level to 0. Unfortunately it seems to have no effect.

Update-2: I've removed icecast and darkice, that i installed some days ago to setup an internet radio station, because i thought they could be part of the problem. Pulseaudio still uses a huge amount of cpu time, and it seems that i'm not the only one with this problem. If you need more system specs, please ask me.
