High-Pitched screaming when taking audio from guitar/amp

[solid viper]

So I plugged my amp into my pc to try and record a backing track and there's this high pitched screaming in the background which is rather deafening, idk how to fix :/

hi! Is your amp connected to a USB port on your PC or is it connected to an an analog audio jack (like a 3.5mm audio jack)?

[solid viper]

it

it's connected via a 6.35mm jack through a adapter to aw 3.5mm, and its plugged into the microphone input

Does your PC includes a line-level input jack (it is commonly blue and is located in the back panel of your PC)?

uhhh lemme check

it does

but I tried that one before and it didn't record anything when I tried it

When you plug in the audio cable into the blue jack go to Audacity and select Transport > Rescan Audio Devices. After that go to Audio Setup > Recording Device and select something like Line Input.

I could try and edit it out using some software but i don't think I'm good enough to do that lol

I think it would be better to try to fix the connection issues instead of trying to remove the noise after the recording. I don't know much about that type of connection maybe other users can help you. For example I know there are direct injection boxes or ground loop isolators that could be helpful in your case. Do you have an image of the amp? to check the specs of the output?

it's an Orange Crush 15R

all I could find for the output specs was "Headphone out"

[vivid fulcrum]

Yes. It looks like the only output is for the headphones.
