I had similar issues with the audio before and fixed it by lowering the VDDG voltage to 0.9v.
Otherwise, you can also try to run MSI Utility v2.
This is one fix I haven't heard yet. I'll try it. Assuming I'll find VDDG voltage in the Bios. Can you tell me what MSI Utility is, what it's for, and what I should be doing with it?
