If you are on a laptop and you can hear an annoying buzzing sound every time you plugged in your earphone (like mine did), here's a quick solution!

Check the laptop's battery at the bottom of your laptop and make sure it is LOCKED. Even if you have no battery inserted (like when you have the power on), just make sure the slider thingy isn't unlock. And that should solve it. Well at least it did in my case...

The lil slider with this symbol means 'locked'.

I've been thinking that it must've been my earphone that's having issues, but the weird thing is it's newly bought! I tried all the noise cancelling options yet nothing worked. Turns out the battery locking was the problem and not the earphone or sound system smh.

UPDATE: Turns out this method doesn't work for me anymore like it once did. Instead try to restart your PC, maybe that'll help.

Dropping by,
