Microphone not working using Skype for Business app on MacOS Catalina

Hi,

I have the foloweing issue. During the call or grup call the microphone is not working.

Skype for Business app is not appeared in the microphone privicy settings so I can’t give permission for this. But the app appears under camera and screen recording privacy settings.

I’ve tried to use an external microphone and it has not helped.

I’ve re-installed the Skype for Business, it’s not helped too.

My Skype for Business version is 16.28.175.

Razmik.

Hi Razmik,

I was having the same issue and came across a couple of articles that did(found on reddit) and did not help, BUT I did get the microphone to work with Skype for business. See below for the steps I took

Step 1: Disable The System Integrity Check so that you can access the relevant system database.

Reboot your Mac and hold Cmd+R on startup. This will bring up the Recovery Mode.
Open Utility > Terminal from the menu bar and type csrutil disable
Reboot to normal mode.

Step 2:

Using the terminal, Open the database by giving command: sudo sqlite3 ~/Library/Application\ Support/com.apple.TCC/TCC.db

Provide your password when requested

Within sqlite3, For Skype for Business audio fix type in command:

INSERT or REPLACE INTO access VALUES('kTCCServiceMicrophone','com.microsoft.SkypeForBusiness',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1541440109);

Type .exit to exit the sqlite3

Skype for Business should be visible in the  Security & Privacy preferences Privacy-Microphone view now

Step 3: Clean up

Reboot your Mac and hold Cmd+R on startup. This will bring up the Recovery Mode.

Open Utility > Terminal from the menu bar and type csrutil enable

Reboot.

Hopefully, this help you as it did for me. :)

Thanks,
