Before using Skype for Business to make a call or join a conference, set up your audio device and check the quality. You can use your computer’s mic and speakers, or plug in a headset.
1. Click Select Your Primary Device in the lower-left corner of Skype for Business.
2. Click Audio Device Settings. 3. Click the menu under Select the device you want to use for audio calls. 4. If you have more than one audio device, pick the one you prefer. 5. Under Customize your device, drag the slider to adjust the speakers and microphone.
Click the green arrow next to the speaker to hear a sample tone.
Adjust and test your microphone. The blue indicator helps you choose the appropriate level. If you have a handset, or desk phone, pick up the receiver and speak into it. If you have a headset, speak into the microphone.
