I just wanted to add my issues to this post. I have the Exact same issues as hellhoundnl and have gone through every step he has to resolve them. Up to and included fresh windows install with new drivers. And have not been able to solve this.

My system is a Rog GA35dx Stock. Amd Ryzen 7 5800 8 core processor. 32 gigs of ram Nvidia GeForce rtx 3080 .

I've tried all the suggested troubleshooting. I've tried using different monitors, different speaker sets, different headsets. In other words using various different audio output hardware and nothing resolves the issue.

I have played through the tutorial without sound hoping that post tutorial something would fix itself. It has not.

I too wonder if its a problem with AMD processors.
