Skype for Business - Mic settings correct but mic not working in Skype calls RRS feed

  • Question

  • We have a user who has a Dell Latitude laptop running Windows 10 Enterprise with Skype for Business installed.  When this user is called or makes a Skype call, nobody can hear him.  He can hear the person on the other end.  We thought this would just be a matter of selecting the correct mic in his settings.  The settings are correct, he can see the mic meter bouncing with noise on his side but the person on the other end isn't hearing anything.

    We tested his mic using a Windows Voice Record app and the mic works and he is able to record audio in this app.  Just isn't able to get his voice to the other end of Skype calls.

    I can do Skype calls with other users and hear them fine so I know it isn't on my end.

    We've had this user try a different computer to see if it has anything to do with his account but it works fine on another computer.

    We've updated drivers on the mic and tested the mic again using the Microsoft Voice Record app to test and the mic works using that app just fine.

    Any ideas on what we can try next?

  • Hi,

    Is this a build-in mic or external device?

    Did other same model machines have this issue?

    Sometimes it may be related drive or incompatible. If you have a working external mic, try it on this machine to check if it could work.

    Also please make sure you have installed the latest SFB version or try with Skype for Business basic version to have a test, just to verify if it is caused by the update of client version.

    If the latest version installed, the issue still persists, please try as follows.

    1. If the issue still persists, please try to reset the default sound device with the steps introduced here.

    2. Update audio driver in Device Manager.

    Scan for hardware changes in Device Manager:

    • Go to Start > Control panel.
    • Search for Device Manager, and then open it.
    • Select your computer name, and then click Action > Scan for hardware changes. This will find new devices and install the drivers.
    • Download the most current drivers from the manufacturer's website and install them.

    In addition, please try to repair the Skype for Business client to see if it could work, that is to uninstall and reinstall SFB if possible.


    Kind regards,
