Plugging in microphone causes speakers to emit loud noises

[karaluh]

As soon as I plug in my microphone, speakers start to emit loud distorted noises. This makes using microphone impossible. The noises persist even when I restart, and go away sometime in the boot process - that is if the microphone was unplugged before the restart. I dualboot and on Windows everything is fine.
