Question Hissing/Buzzing noise from the speakers when computer is used

[rahilpathan56]

Please check my the wiring diagram below and let me know If I am doing anything wrong.

I am using Logitech z506 speakers and connecting two monitors and one chromecast ultra.
Whenever I use my PC move mouse around it makes a buzzing noise in my speakers.

It is connected to a common UPS by APC. But I tried to use other wall socket for speakers but no good.

Please let me know... Thanks !

Try cleaning the aux ports, possible you're not getting a clean connection

It's a brand new setup.
I did try to rewire the whole thing to avoid any speaker cable near power cables. But, nothing good pal. Thanks for the reply.

Oddball option, but i had a friend who got the same problem on BFV, try disabling your windows sound effects.

Uninstall all of your sound drivers
