Thanks! I just tried this rc6 version on my machine, and sound plus nvidia drivers work fine with this. In addition to the described steps, I also did run a "make headers_install", to make sure that nvidia could compile it's module.

My machine: Lenovo Legion 7 16ACHg6 82N6 - Laptop 16" IPS 2560 x 1600 (WQXGA) 165 Hz - AMD Ryzen - with 3 external monitors connected and working (2560x1440).

I hope the patch gets propagated soon to a real release.
