Comment(by psihozefir):

 I took the time this morning to test various module configurations and I
 found out that indeed one of the RTP modules cause my CPU to increase its
 clock freqncy.
 If I enable both the following at the same time, not separrately:

 load-module module-null-sink sink_name=rtp format=s16be channels=2
 rate=44100 description="Sputnik RTP Multicast Sink"
 load-module module-rtp-send source=rtp.monitor

 then my problem starts to show up.
 Whn module-rtp-recv is enabled (but not rtp-send), everything is fine.
 Also I aded tsched=0 to module-udev-detect and I made my tests with this
 configuration in place.
 I'm sorry for my previous statements where I said that without the RTP
 module the CPU stays at 2 GHz.
