To use your sound with apps on Windows 10, you'll need to turn on some permissions in Camera settings. Then, you'll need to check your app permissions to use your camera with apps. 

Here's how:

1. Select Start  > Settings  > Privacy > Camera. In Allow access to the camera on this device, select Change and ensure Camera access is turned on.
   
2. Then, allow apps access to your camera. In-Camera settings, go to Allow apps to access your camera and ensure it's turned on.
   
3. Once you've allowed camera access to your apps, you can change the settings for each app. In camera settings, choose which Microsoft apps can access your camera and turn on the apps you want to use with it. For desktop apps, make sure that "Allow desktop apps to access your camera" is turned on.
