So just revisiting the Vive Pro again recently i decided to try that and well it does look like i got my audio working again on the Vive Pro. I just updated to the latest NVidia drivers, rebooted everything and the NVidia Audio now shows up in the VR settings in Steam. Selected that, and now I got "clear" audio again through the Vive Pro's ear peices. The audio is still nothing to get excited about (i even think the sound coming from the Oculus Quest positional audio is slightly better) and I'm still considering removing the earpeices and using my own wireless headphones, but at least for now it's clear again and the crackling is gone. With that said, Yay.
