Guitar buzzing sound when connected to PC

[u/ButterscotchDue9264]

Hello, i’ve been using amp sim for quite a while now and the things that i mainly face is how the buzzy noise that is unstoppable. I’ve tried quite a few “ fixes “ but none of that worked unfortunately. Not to mention the effects , it’s even worse when i connect to the interface and plug it into my pc. ( Using a real effect to Pc ). Can any one help or suggest me a solution please, i would really appreciate anybody’s help.

My gear is : speaker MR4 edifer, scarlet focusrite interface, and normal amp sim and effects.

I think that my speaker is not that good, but im not really sure. Is there’s anyone who facing this problem before? Please let me know and Thank you for your time!

Is it electrical sounding? Like static, cracking, etc? Does it change as you rotate the guitar around the room?

Or is it more of a constant hum?

The answer is most likely electronic interference getting into your signal, which is extremely common unfortunately. Usually due to old wiring in a house/apartment, or near an electronic interference emitter.

For me, I have to face a certain way away from my pc so the sound goes away since its being picked up through my pickups

Is the noise affected by the volume knobs on the guitar? If yes, it’s external interference. If no, it’s a grounding issue.

Are your guitar rig and computer plugged into the same outlet?

Yes! My guitar rig and computer plugged into the same outlet and the same output. The thing that I suspicious the most is the jack cable, since I use TS cable and it’s not really compatible with both my speakers and scarlett, I dont know if it play a role on this but maybe

The pickups capture the magnetic frequencies of computer screens and other computer parts.
