Hello,
I'm developing a WebXR application in Safari on visionOS. This app uses the microphone input in WebXR.
I've noticed that with the microphone permission allowed the audio input doesn't capture. The size of the blob is always 0.
I made a small demo here: https://github.com/chrisdubya/avp-threejs-webxr-test
I've tried this demo on other WebXR supported HMDs and the audio capture works fine.
