On advice I'm going to copy and paste a post I made elsewhere on the forum. Looking for advice on whether I have a ground loop. Also I accidentally used DirectSound for the direct connection test but I re-tested it with MME and the results are identical.
Hello
I'm looking to for help interpreting some RMAA results from an odac+O2 combo connected to one of my computers. I can't judge whether I am looking at an actual ground loop between my computer and the odac or one between the odac and my PCs line-in. Some large screenshots incoming.
This is what I get with a direct connection to my pc
And this is what I get with a hifimediy USB ground isolator
Also since I had one lying around here is what a direct USB connection to the pc looks like using a Behringer HD400 Hum destroyer instead of a standard audio cable
And here is the mess I get if I combine the Hd400 and the USB isolator
