Unusual, high pitch noise when nothing's using audio. Caused by Nvidia?

Hi everyone! :hattip:
I have some issues with sound in my laptop. When charger is plugged in, battery is full and there is no source of sound, there is very loud and irregular buzzing in headphones. To add salt to injury, even when this hiss isn't present there is a 2nd one although much quieter and less annoying - sounds like a regular coil whine - and this one persists even when disconnected from power grid/something is playing. It only occurs in stuff plugged into audio jack. External DAC sounds like a dream.
I tried to mitigate it with *sudo tee /etc/modprobe.d/snd-hda-intel.conf <<<'options snd-hda-intel power_save=0'* command and it changed nothing. Also tried to mute built-in microphone in pavucontrol to no avail.
I believe it isn't problem with ground loop or anything like that as I didn't experience it in Windows/majority of live ISOs.
But! I figured out a way to make it stop:
When *nvidia-settings* is open, all the noise stops. I assume it's the GPU's fault then.
So, does anyone have an idea how to achieve this behavior without having to keep nvidia-settings open or/and why this is at all happening?
I don't know what info can be useful but I'm using Acer Nitro 5 AN515-55 (Intel i5-10300H with NVIDIA GeForce RTX 3060 Mobile), ArchLinux, pipewire/wireplumber/alsa, LXQt
Thanks for reading and thank you in advance for trying to help! <3
Cheers
