Question Audio crackling

[Eplex]

I'm experiencing audio crackling in my headphones after fiddling inside my case, as I was reseating my CPU.

I've tested several headphones, all the same. It does not follow the headphones, as they work on my laptop.

USB-ports all the same.

Is it safe to say there's something with the motherboard, can this be determined someway?

My monitor plays sound perfectly without any issues.

Hi, I have replied to your other post regarding the same. If you can confirm that you are using a discrete GPU, we can narrow down the problem to your motherboard.
