Windows blocks microphone in certain program

In Windows 10, my microphone works fine with some apps like Skype.

I've installed Teamviewer and the microphone is blocked, so the other side doesn't hear me.
I suppose it is blocked by Windows.

I opened Settings > Privacy > Microphone with the intent to allow Teamviewer to use the microphone.
This settings window should show desktop apps too, like here:

where Teamviewer and any other program should be listed.

However, my machine shows only the Windows native apps, like here:

therefore I can't check or modify the settings for other apps including Teamviewer.

Is there any othe way - including editing the registry - to allow particularly Teamviewer to use the microphone?

Any hints appreciated.

 

FIREWALL IS BLOCKING CERTAIN PROGRAMS

Hi Joseph,

Thank you for posting on Microsoft Communities.

I will be glad to help you with the issue you have with the computer. I understand the frustration when things don't work the way it should.

One of the most common problems when using a network firewall is that it sometimes blocks network traffic that you want to allow.

Please follow the below step to troubleshoot with the issue:

• Open the “Control Panel“.
• Select “System and Security.
• In the Windows Firewall section, select “Allow a program through Windows Firewall“.
• Unchecking the box to the left of the application name disallows it from accessing network resources, while checking it allows access.
• If the program you wish to block or unblock is not listed, you can click the “Allow another program…” button to add it. Choose the application in the list and select “Add“. If the program is not in this list, use the “Browse…”
  button to select the program file manually.

Hope this information is helpful. Please post in case you have any further issues, I will be glad to help you further.

Thank you.

 

Block ALL Programs Except Allowed Ones

You can block programs using Windows Defender, for example (ignore the strange title):
