Hi jcutolo,

Do you mean you running Windows OS on your MacBook Pro ?

(Note: Lync 2010 is supported on Windows platform, Lync for Mac 2011 is supported on OSX platform.)

If its Lync 2010, does it work with Lync for Mac 2011 on the same MacBook Pro ?

If its Lync for Mac 2011, you might try the following suggestions.

1. Install the latest update of Lync for Mac 2011.

2. Use a certified device to test.

3. If your preferred device was not automatically set as the default audio device when you connected it, you can change it by clicking the microphone icon in the lower left of the main Lync for Mac window, and selecting your device from the pull-down menu.

4. If you are having audio problems, and you can't resolve them within the Lync for Mac client, you can specify the input and output devices in your system sound settings:

   a. Open System Preferences and select Sound.

   b. Select the appropriate settings for "Output" and "Input".

Hope it can be helpful.

Best regards,

Eric

Eric,

No, I am using Lync 2011 on the Mac OS (Yosemite 10.10.3).  I updated the last update and it seems it was a bad update (Outlook no longer is opening, which Microsoft knows about).  My headset mic was working fine till this last update, so I am now wondering if this is something with this entire update from Microsoft.

Hi jcutolo,

As I know, the MacBook Pro has a built-in microphone, does it works ?

Best regards,

Eric
