Hello,
I've been having an audio interference issue with both USB and audio jacks ports. Using USB soundcard (Creative Omni Sound Blaster Surround 5.1) my microphone seems to pick up some random noise from the computer. If I use the 3.5mm audio jacks, the output sounds will be played through microphone (basically other persons will hear what I hear too). I can't use my monitor speakers while playing either because I will get a squeaky sound like a GPU coil whine.
I had these problems with two different builds, mounted in the same case and PSU, basically I changed my motherboard, CPU, GPU.
I am at a loss to figure out where the issue comes from, if you guys have any idea it would be much appreciated. I tried using different headsets and microphones, but it didn't help. Plugging the PC into another plug in the room didn't help either.
Thanks in advance for helping me out, sorry if I made any english mistakes.
