I was wondering where to start looking with groung loops in a computer.
I have secondary PC AMD Phenom II which has been humming Via a USB Audio device via a mixing desk .
So it goes like this. Mixer---USB Audio---PC output---humming
At 1st i thought maybe i didnt ground the PC so i stripped it down regrounded and even used plastic stand offs too after rebuilding it back together ...nope the humming was still there.
I tested the same Mixer---USB Audio---PC output on my new AMD FX ,well no humming !!
So im stumped why it does this on one pc and not the other .
Any ideas people ??
