Ah thanks a lot for the mixxx.cfg. I can reproduce this! (on macOS, 2.2 beta)
The graphic EQ effect parameters in your mixxx.cfg are way outside the valid ranges of -12 to 12. These parameter values aren't validated when we load them, and they cause the graphic EQ effect to go absolutely crazy on my machine, and as you say, cause really loud noises even when no tracks are playing.

Starting over with a new profile disabled the graphic EQ effect, and cleared the parameter values.
Now I'm wondering how those got there in the first place. Are they valid for the parametric EQ effect?
