[SOLVED] Static background noise when using amplifier. How do I fix?

[Babsdaknasher]

I want to split the audio from my pc to my headset and speaker at the same time. I had purchased an amplifier and routed accordingly. In the background I get a light static buzz and a louder buzz when I move my mouse. When I unplug one device so that only one device is using the amplifier, everything sounds normal. How can I fix the issue? Would using a ground loop noise isolator work? Or is there a better way to split the audio to both devices?

Also I did try using realtek audio driver to use a stereo mix so that the sound could be split. When that's downloaded my mic sounds extremely low thus needing to use boost on mic settings leading to a <Mod Edit> sounding mic. I ended up just uninstalling realtek audio driver.

Yes you need a ground loop isolator. Issue is the fact it's a "headset" not just a headphone so you need to split the mic to another place.

I just ordered the isolator and will give an update when I try it. But both the headset and the speaker have the static, as well as earbuds that are plugged in too. The mic is wired directly into the back panel of pc and headset wire goes into the amplifier.
