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.

@EnigmaCurry thanks! I found that out in the meantime. Pretty cool. I also found out

Keep an eye on the CPU load for each of the above. Use "0" instead of "1" as the last character to unmute. – joat – 2019-01-26T14:02:19.697
Switch to Arch. Everything's fine now :) – klingt.net – 2014-02-24T14:04:25.323
