Issue   Other Microsoft Lync 2010 users complain that your audio is cutting out or popping.

Resolution   Make a test call, and then adjust the microphone settings on your computer. Depending on your computer’s sound card, you might need to adjust the microphone or Microphone Boost levels if they are set too high by doing the following:

  1. Click Start, and then click Control Panel.

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

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

  4. On the Levels tab, adjust the microphone level and the Microphone Boost level, if it is available.

  5. If that does not resolve the issue, clear the Microphone Boost check box, if it is available, and then try again.

If you are still having an issue and you are using a noise-canceling microphone, make sure the microphone is positioned approximately two centimeters (slightly less than one inch) away from your mouth. This filters out unwanted background noise.

Also, make sure the device you are using is optimized for Lync 2010. For a list of optimized devices, see “Phones and Devices Qualified for Microsoft Lync” at

Finally, before making or receiving another call, it is important that you check the audio quality of the selected device by doing the following:

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

  2. Click Check Call Quality to make a test call, and then listen to how you sound when using the selected device.
