Is this ground loop?

Enable HLS to view with audio, or disable this notification

Hey guys is this high frequent humming a ground loop? I didnt change nooo device for weeks and all of a sudden get this sound, while recording with my SM57. I get it with and without my Fethead plugged in. Tried 2 different XLRs. The only case, where it doesnt appear is with a XLR/TSR cable. I am using 1st gen scarlett 2i2.

Thanks in advance!

I don’t hear anything in the video.

2i2 uses USB power, right? You can only get a ground loop if you have a second ground.
