navigator.getUserMedia mutes (partially) the other sounds of the computer.
What can I do to make it not happen? Some additional parameter?

Could you try to explain another way? I'm not understanding what "dims the control computer" means. – Jacob Mar 27 '15 at 00:26

Also you should assume that we don't speak the language of your title (polish?), and translate that too. – Elliott Frisch Mar 27 '15 at 00:28

Your question is not entirely clear to me, but I'm going to venture a guess about what's going on...
Unless you are wearing a headset, most microphones pick up the sound emitted by your system, which, depending on where it is output, can feedback quite badly. For this reason, getUserMedia implements echo cancellation by default, which is quite desirable for uses like WebRTC calls.
Unfortunately, Firefox does not currently have a way to turn this off, but this is being worked on. Once this is fixed, then the standard way to disable it should work, which would be to pass in an { audio: { echoCancellation: false } } constraint to getUserMedia().
To verify if this is your problem, try going to about:config and setting media.getusermedia.aec_enabled to false.
If this does not match your symptoms, then please elaborate.

Did Not. That's not it. The idea is that the sound example of foobar2000 is muted during recording. I want to not mute. – lukaszpolowczyk Apr 07 '15 at 14:42
