You can’t always remember to right-click on a program and select Run as Administrator whenever you want to open it. But you’ll have to do that whenever you want to run the program. The fastest way to run a program as an administrator is by right-clicking on its shortcut or Start menu listing and selecting Run as Administrator from the context menu. Note that your user account has to be an administrator account for this to work. This method worked like a charm for many users. You’ll have to grant both programs administrative privileges to fix the issue. If you’re running Discord and Chrome normally, this could be the problem.
In that case, you will have to double-check if you have allowed the microphone from your privacy settings. It’s possible that you can’t unmute yourself on discord because your privacy settings aren’t allowed discord to use your microphone.
