Hi,
I got my Hp Reverb G2 today and I’ve had the exact problems from the first flight and it seems to appear every 5 minutes or so. Since I only have the headset as my audio I cannot verify that the audio switches from the headset to the desktop audio but I assume it does. It changes the volume from 100 to 65 (which is my master volume in windows). The game sometimes continue without sound but then it can also get black for 5-10 seconds and the it returns to normal.
I first thought it could be a loose cable but it’s not the case. It must be something with the USB-C connection. I will try using a USB-C to USB3 and see if it resolves my problem. I now have the HO adverb G2 connected to a USB-C in the back of the computer. Disconnecting the sound and move to a headset could be a solution but getting new drivers seems like a better solution. I know that Oculus Rift S had problems to connect with some USB drivers on my old ASUS motherboard when I gave that 3590K to a kid who wanted VR. Buying a new separate USB card was the solution there.
My current setup is a MSI Tomahawk MAG Z490, 10900K stock speed with Noctua NH15, 32 Gb ram, Samsung V-Nand860 EVO 1 TB, Samsung V-Nand960 EVO plus 1 TB, ASUS Strix 2080Ti.
