If other callers are complaining that your audio is cutting out or they hear a popping sound, you’ll need to make a test call, and then adjust the microphone settings on your computer. Depending on your computer’s sound card, you may need to adjust the microphone gain or Microphone Boost volume levels if they are set too high.

  1. Click Start, and then click Control Panel.

  2. In Control Panel, click Hardware and Sound, and then click Sound.

  3. In the Sound dialog box, on the Recording tab, select your microphone, and then click Properties.

  4. In the Microphone Properties dialog box, on the Levels tab, adjust the microphone (and Microphone Boost, if available) levels.

If that does not resolve the issue, clear the Microphone Boost check box if present, and try again.

If you are using a noise-canceling microphone, make sure it’s positioned close to the mouth, approximately two centimeters or less than one inch away from the mouth. This filters out unwanted background noise, so it is important that you position it correctly to avoid audio issues.

Also, make sure that the device you are using is optimized for Microsoft Lync Online communications software. For a list of optimized devices, see Phones and Devices Qualified for Microsoft Lync.

Before making or receiving another call, it is important that you check the audio quality of the selected device. To check the audio quality, do the following:

  1. In the lower-left corner of the Lync main window, click the audio device menu Select Audio Device.

  2. Click the Check Call Quality button to make a test call and hear how you sound using the selected device.
