Webrtc cannot be used properly on Hololens 2

Platform :  HoloLens 2

Edge Version :  Edge latest version 94

Problem :  WebrTC cannot be used properly.

Using any weBRTC example is problematic. Looks like the microphone won't open, can't open the microphone and camera head.

Under PC windows10, webrtc can be used normally.

Please solve it as soon as possible. Thank you
