In the Sound Recorder, clicking the red circle does nothing.

Resolution

The app needs permission to use your microphone:

1. In Chrome, type this into the address bar and press the Enter key:
   chrome://settings/content/microphone
2. Enable Sites can ask to use your microphone.
3. If the app's website is listed under Not allowed to use your microphone, click its Bin icon to remove it.
4. Back in the app, try recording again. When prompted, click Allow to let the app use your microphone.

If the issue continues, your microphone may be blocked by your IT Support. Please forward this article to them.
