How are all of your speakers connected to the PC? Generally, the sub should have its own channel so it shouldn't make any noise with the satellite speakers. It should only make noise when it is testing the sub channel. It sounds like you have it plugged in along with the left and right channels. You want to make sure your sub output on the computer is going to the sub channel on the back of the amp.
Subw/center -> RCA to 3.5mm
Front speakers -> RCA to 3.5mm
Back speakers -> RCA to 3.5mm
All of them plugged in their own slots as my motherboard says.
When I test my front speakers, bass working but for my center and back speakers, it's not. My center and subwoofer are connected to Center/LFE like Left and Right.
