Hi everyone, so since today i have an issue with my audio. And it seems to happen when i start OBS.
ive looked this up multiple times and all i could find was actually mic related.
Let me post my setup

Gaming pc:

i7-4790K
maximus vi formula
GTX1080
16gb Ram

Stream pc:

i5-4690K
h81m-a (mobo)
GTX780
4gb Ram

Mixer:

Behringer Xenyx 802

so the problem im having is: as soon as i start obs (classic and studio have the same problem)
my audio is starting to hum. and its driving me nuts, changed the audio cables to see if the problem was a faulty
cable but that doesnt seem to be the issue.
I hope any of you knows a solution to this cause im getting nuts atm!
Im not using a directly on the pc so thats disabled in settings, everything is done in the mixer.
i will post a log if needed,
