Double Sound?

[Sad_lynx]

I don't know what else I could do. I just hear the double Sound.
Settings:

Audio: Desktop Audio: default
microphone/AUX Audio: digital audio interface (?) (USB3.0.capture)
And the rest is deactivated
Audio Mixer:
Desktop: monitor off
Mikrophone: monitor only

Is the mic audible in Desktop Audio, and then you've added the mic as a separate (2nd) audio source?
