Microphone not working on Mac OS Big Sur
I run Mac OS Big Sur in my MacBook Air Early 2015 model, model no. A1466.
For the past 3 months, I have been experiencing an issue of the in-built Microphone not working for programs other than Siri and Keyboard dictation. The microphone works fine for Siri and Keyboard dictation but, doesn't work for any other programs. I have checked all the required privacy settings and considered all the tricks available on the internet, and still, the problem persists.
But, my microphone works fine for other applications too, if I open System Preferences>Keyboard>Dictation in the background, and let the System Preference tab be open. But, as soon as I close the System Preferences tab my in-built microphone doesn't work again.
But, if I connect an external microphone, everything works fine, the above-mentioned problem doesn't persist.
I need a solution for this.
MacBook Air 13″, macOS 11.3
