Question Superlux E205 buzzing problem

[ryusxd]

What's up guys.

I bought a new microphone like 2 weeks ago, it's the Superlux E205, also a needed mixer, which is the Behringer Xenyx Q502USB.
Sounds nice to this point, except there wouldn't be a problem: When I start up Audacity, my microphone is buzzing somehow, or it sounds like that.
The buzzing came like 3 days ago, out of nowhere.

If you don't know what I mean: https://instaud.io/3YtB

I'm glad If you can help me.

Mind sharing how the audio equipment is connected to your system? You might want to see if reinstalling your chipset/USB drivers changes your experience.

Microphone is connected with an XLR-cable to the mixer.
The mixer is connected to the electricity and to the PC (USB type B in mixer to USB type A in the PC).
Realtek Audio Driver, no external sound card available or something.

After reinstalling the Realtek Audio Driver the problem is still there.
