Built in system microphone doesn't work on my HP Envy

[Bob_Martin-AZ1]

Hello. The built-in system microphone on my HP Envy Evo with Windows 11 doesn't function properly. Microsoft Support spent over an hour logged into my computer and couldn't diagnose the problem. They said it had to be an issue with the computer and I should contact HP. I see others have had the same problem. An advice?
