System interrupts and CPU

[alexsama]

Hi all, i noticed a strange event at the ResourceMonitor, somehow, the process System Interuppts starts growing at Average section when i speak at the microphone on TeamSpeak, Xfire or Skype(any chatting software). I installed and update all the drivers, i have two microphones. One microphone is on usb connection and System interuppts gets to 8-10 at ResMon Average. Even in Task Manager the CPU is high and in Process section i can't find any System interuppts. If i use my 2nd microphone which is 3.5 jack connection the System Interuppts in ResMon is <5 at Average, lower than the microphone on usb, why is that? why all microphone use the system interuppts so much that in time it eats my cpu usage?

5-10 is hardly that high or something to be concerned about. But USB is a CPU bound bus, it will use the CPU for all USB traffic.

So i can consider it normal?
