Troubleshooting audio in Skype for Business

Can't hear anyone in your Skype for Business call? Or does no one seem to hear you?
Let's try to fix that.

Make sure you're not on mute

In your call, take a look at the microphone button, if there's line through the microphone then you are currently on mute (silenced), click the button to unmute yourself.


Is there a line through your microphone icon? Then you're on mute - click it to unmute yourself!


This icon is good! You're no on mute.


Quick tip: You can also press Windows Key + F4 on your keyboard to mute/unmute.

Select the right audio device for the call

In your call, click the Call Controls button in the lower right then, click on the Devices button . Skype for Business will now ask you which audio device you want to use. Click on the one you want to use.

Skype for Business will show you several compatible audio device options. if your device is not in this selection, please make sure you've plugged it in and turned it on.

Look at your device's mute buttons

If you're working on a device like a laptop, it might have a dedicated mute button for the speakers and microphone, on the keyboard or elsewhere.

Look for these buttons on your device and make sure you are not on mute.


Using a headset? That might also be on mute

If you're using a headset that has it's own mute/unmute buttons, double-check that it's not muted.

Check your headset's user manual to identify the exact location of this button.


This is an example of a Lenovo laptop. These buttons may be in a different location on your device.
