Topic: Audio background noise with RME Babyface connected to guitar Rack
I keep working on my new pc built dealing with every issue that comes along.
Most recent was this, to which I have not found an explanation but at least I can go on working

Another issue that has popped up is a strong radio frequency interference or electromagnetic interference when I play my guitar through my regular rig which comprises of a series of rack mounted effects, like, a compressor, a parametric eq, a delay system, a reverb system and an amp simulation unit, plus one or two occasional pedals. This rig I have been using extensively in the past 6 years with cubase and a focusrite on my previous laptop pc, and for 6 months on the same laptop with my RME Babyface pro FS.
When I used hi gain settings I did have background noise but now it is definitely louder and more clear that it is some kind of EMI or ground loop and came into existence with the new built (a desktop tower with a ryzen5 3600xt, on Asus prime b550m-wifi MB, gigabyte 1650 graphics)
I don't have the problem or at least it is not noticeable with clear settings with no excess of gain, but it bothers me because it was not there.
I include a video link that shows also the bios monitoring of the MB to see the relation of the noise to the changing of the cpu frequency and fans etc...
