Short Answer

Static that follows mouse movement is electrical interference from the USB port or a ground loop. Move the cable, try another USB port or add a USB isolator.

The mouse sends USB signals that can leak into an unshielded audio cable. A ground loop or a cheap motherboard audio chip makes it worse.

A different port or a short shielded cable often removes it.

Step By Step Fix
  1. Use the rear panel jack and keep the audio cable away from USB and power cables
  2. Plug the mouse into another USB port
  3. Use a ground loop isolator on the line
  4. Try a USB audio adapter if the motherboard audio is noisy

    Ground loop isolator did it, 10 dollars. It took me a few minutes, and the Speaker Test showed the difference straight away.

    Moving the cable away from the power brick was my fix. I checked it again with the Speaker Test afterwards to be sure.
