My Microphone Sound Input has Disappeared on Windows 10

Contact System-F Limited

It happened again, the aliens have invaded my system and my microphone sound input has disappeared on Windows 10.

Well OK, not aliens, it was Microsoft.

One of my machines, the one that I do most sound recording on, just stopped recording from a microphone! It’s a windows 10 machine and one of the microphones that I use is on a Microsoft Lifechat 3ooo headset. It became a problem when I fired up Audacity and it couldn’t open the microphone so I couldn’t record.

To cut a long story short, and it was about 3 hours of my life:

I just had the 2018 autumn update of Windows 10.

It took me a while to realise the significance of that statement.

The Microsoft update turned off access from my sound programs to save me from spying.

If you have the same problem then on the magnifying glass icon at the bottom right of the screen type microphone security and it should look a bit like this:

The bit to change is where it says Allow apps to access your microphone. You can either go down the list and set each program that might want access to allow it to do that or you can let all apps access your microphone just like it used to be.


I’m back up and running and a little more grey in the hair.
