1) In the lower-left corner of the main Skype for Business window, click the audio device icon.

2) Either choose the audio devices that you want to use or click Audio Device Settings to set up a new audio device.

3) Next to "Speaker", click the green play button to hear a sample tone. Drag the slider if you need to adjust the volume.

4) To test your mic volume, speak for a few seconds. The volume is optimal when the progress bar reaches the middle of the test area while you are speaking. Drag the slider next to "Microphone" to adjust the mic volume.

5) Next to "Ringer", click the green play button to hear a sample ringtone. This simulates getting a phone call. Drag the slider to adjust the ringer volume.

6) Click Check Call Quality and follow the prompts to record a short message and play it back. Adjust audio, as needed.

NOTE: This option may not be available for your account.

7) If you have more than one audio device, you can choose to set both to ring when you get a call. Under "Secondary ringer", choose "Also ring", and then choose an additional device. You can also choose "Unmute when my phone rings", which will automatically unmute your speakers when you receive a Skype for Business call.

8) Choose "Allow stereo audio playback when available" to make sure that the best audio quality is available during a meeting.

9) Click OK.
