Exact same problem with a Radeon 5700 and Adrenalin 19.7.1. I suspect the drivers are the issue, as it worked fine on my Radeon RX470 with Adrenalin 19.5.2 if I recall correctly.
Would be great if AMD could confirm this or not.
how ? just switch in the steamVR ? because the HDMI is connected to my RAdeon 5700 not to the mobo... or can it go through anyway ?
the audio from the motherboard works fine but I want the sound in my headset, not on my desktop speakers ....
Beat Saber 144hz 130%SS, Superhot & Space Pirate Trainer the same. Other games like Elite Dangerous and Pavlov are bottlenecked by my CPU so either 120hz or 72 reprojected stable with the GPU not fully used
This did not work for me. I'm not using a VR setup currently, but am having those same issues. I just did a clean install of the newest Adrenaline Driver (19.9.2) and I have no sound coming from the GPU output. I am able to get sound from the audio outputs on the motherboard, but not my RX 5700 XT. This is rather frustrating.
