Problem
Microsoft Teams meeting audio is not working. You may not be able to hear other people, they may not be able to hear you, or both speaker and microphone audio may fail at the same time. In some cases, audio works before the meeting but stops after joining.
This is usually caused by the wrong speaker or microphone being selected, muted audio, device permission problems, Bluetooth headset issues, browser permissions, or another app interfering with audio devices.
Solution
Check your Teams audio device settings, confirm your speakers and microphone are not muted, test audio outside Teams, and reconnect any headsets or external devices. If you are using Teams in a browser, confirm the browser has permission to use your microphone and speakers.
Step by step instructions
Check the simple meeting audio controls first
Start with the meeting controls before changing device settings.
Check the following:
- Your microphone is not muted in the meeting
- Your speaker or headset volume is turned up
- Your device is not muted at operating system level
- You have joined with computer audio rather than phone audio
- Your headset is powered on and connected
- Your Bluetooth headset is not connected to another device
If audio starts working after these checks, the issue was likely a mute or device selection problem.
Select the correct speaker and microphone in Teams
Teams may choose the wrong audio device, especially if you use a headset, dock, monitor, webcam, or Bluetooth device.
Open Microsoft Teams.
Select Settings and more near your profile picture.
Go to Settings.
Select Devices.
Check both:
- Speaker
- Microphone
Choose the devices you actually want to use.
For example, if you are using a headset, set both speaker and microphone to that headset where possible.
Check audio before joining a meeting
When you open a meeting invite, look at the pre join screen before entering.
Check the selected audio device.
Turn the microphone on or off as needed.
Confirm you are joining with computer audio.
If the wrong device appears, open device settings from the join screen and select the correct speaker and microphone.
Make a test call
In Teams, open Settings.
Select Devices.
Choose Make a test call if the option is available.
Record a short message and listen to the playback.
Use the result to identify the issue:
- If you hear the playback, your speaker is working
- If your recorded voice is heard, your microphone is working
- If you hear nothing, check speaker selection and volume
- If your voice is missing, check microphone selection and permissions
Check Windows sound settings
Open Settings in Windows.
Go to System.
Select Sound.
Check the selected output device and input device.
Make sure the correct speaker and microphone are selected.
Also check volume levels for:
- Master volume
- Output device volume
- Input microphone volume
- Microsoft Teams app volume if visible in Volume Mixer
Restart Teams after changing sound settings.
Check macOS sound settings
Open System Settings.
Go to Sound.
Check both Output and Input.
Select the correct speaker or headset under Output.
Select the correct microphone under Input.
Test the input level by speaking normally.
If Teams permissions were changed, quit Teams and reopen it.
Check browser audio permissions
If you are using Teams on the web, go to:
Check the browser’s site permissions.
Allow microphone access for Teams.
Also make sure your browser is not muted in the operating system or browser tab.
After changing permissions, refresh the Teams web page and rejoin the meeting.
Reconnect Bluetooth or USB audio devices
If using a headset, disconnect and reconnect it.
For USB devices:
- Unplug the headset
- Wait a few seconds
- Plug it directly into the computer
- Avoid USB hubs during testing
For Bluetooth devices:
- Disconnect the headset
- Reconnect it in Bluetooth settings
- Make sure it is not paired to another active device
- Select it again in Teams device settings
Close other apps using audio devices
Other apps may hold the microphone or change audio routing.
Close apps such as:
- Zoom
- Skype
- Google Meet
- Discord
- Voice recorders
- Browser tabs with meetings open
- Headset control software
Then quit and reopen Teams.
Restart Teams and your device
If audio still fails, fully quit Teams.
Restart your computer.
Open Teams again and test audio before joining another meeting.
A restart often clears stuck audio services and device conflicts.
Optional methods or tools
- Use Teams on the web to test whether the desktop app is the problem
- Try a wired headset if Bluetooth audio is unstable
- Use Windows Sound settings or macOS Sound settings to test input and output
- Try a different USB port for wired headsets
- Ask your IT team to check device restrictions on managed computers
Best practices or tips
- Test your speaker and microphone before important meetings
- Use one headset for both speaker and microphone where possible
- Avoid switching audio devices during a live meeting
- Keep Teams, headset firmware, and audio drivers updated
- Restart your computer after major operating system updates
Microsoft Teams audio problems in meetings are usually caused by device selection, mute settings, or permissions rather than a fault with the meeting itself. Checking both speaker and microphone settings inside Teams and your operating system resolves most cases quickly.
If audio works outside Teams but fails inside a meeting, compare the desktop app with https://teams.microsoft.com to narrow down the issue. For repeated problems, a stable wired headset and updated Teams installation can make meeting audio much more reliable.
