I updated my Vision Pro to VisionOS 2.0 Beta yesterday, and now everything is very quiet even at max volume. I tested with the built in speakers, Beats Pro and Airpods Pro Gen 2 as well and same problem with all of them.
If I turn the volume down to 50% you cant tell what audio is being played anymore.
I tried restarting the headset and it makes no difference.
Anything else I can try to resolve this issue?
