Skype for Business Microphone not working

Skype works fine, however, no one can hear me on Skype for Business. No microphone access requested in Privacy and Settings, though with regular Skype there is access. IT guy tried everything. (OS X Catalina 10.15.4)

Hello Ironman611,

Regarding to your problem, firstly, please make sure your Skype for Business is up to date. Since you mentioned that no microphone access requested in Privacy and Settings, do you mean you have checked the System Preferences > Security & Privacy > Microphone but Skype for Business is not in the list? If so, I suggest you try the following steps and check whether it works:

1.  Disable SIP protection in your Mac.

2.  Make a backup copy of the ~/Library/Application\ Support/com.apple.TCC/TCC.db file

3.  Open Terminal and run sudo sqlite3 ~/Library/Application\ Support/com.apple.TCC/TCC.db to open the database TCC.db.

4.  Provide your password when requested Within sqlite3.

5.  Run the following command:

   INSERT INTO access

  VALUES('kTCCServiceMicrophone','com.microsoft.SkypeForBusiness',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1541440109);

6.  If you receive some error, try this command:

   REPLACE INTO access

   VALUES('kTCCServiceMicrophone','com.microsoft.SkypeForBusiness',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1541440109);

7.  Type .exit to exit the sqlite3.

Then check whether Skype for Business shows up in Security & Privacy settings and check if the microphone works in Skype for Business.

If the issue still persists, please feel free to let me know and provide the detailed version of Skype for Business to me.

Regards,

Seven
