How to detect if microphone permissions have been granted in chrome

Question

I would liked to detect whether or not microphone permissions have been granted on my site when it loads without actually running something like the following:

n         


        

Answer 1

navigator.getUserMedia is now obsolete, replaced by MediaDevices.getUserMedia, which returns a promise. If the promise gets rejected you get an DOMException with indication of the problem. Insufficient permissions is one of the options there.
