I wouldn't call this resolved. This is just a useful step in
troubleshooting. You now have more information towards a resolution.
That's a good thing, but not enough.

Don't assume that there are actually two issues here. It may all have
one cause or be two (or more) different problems.

Did you troubleshoot your earphones? It is very reasonable that they
could now have bad wires or other problems. Do you still hear these
noises with other earphones or speakers?

I advise finding out what the problem is before buying anything new. You
might find the same problem getting passed through another audio device.
I suspect that you will need to fix a hardware problem.
Don't assume that audio noise is in software.
You are surrounded by 50/60Hz noise caused by the power in your
house/office/workshop.
Electrolytic capacitors can go bad (Even brand new capacitors can be
defective). Look up bad motherboard capacitors and you can find some
pretty good pictures and information. You can find some good YouTube
videos on it too.
I would also suspect grounding problems as a possibility.
Which can mean bad connections with cables even if they look good.
You can be having a power supply problem too.
Check for loose motherboard screws.
Are you using the computer with the cover off?
Do you get these noises with the computer on, but then turning off the
monitor and moving the mouse around?
Is your electrical wiring done properly? Do you have any other equipment
hooked up that might be causing ground loops? Excellent videos on
YouTube about ground loops and audio problems. Do you have any OLD radio
or TV equipment that could be latching onto the computer noise and
amplifying it?
Also, if you can, go unplug (not turn off) things around that could be
defective. For example, I have to throw away 3-4 USB chargers every
year. Nowadays, hardly anything is actually turned off anymore.
I used to hear noises like these too, but that was a long time ago...
I could hear them in my memory while reading your email.
Good luck,
