How to Change Audio Sources in Microsoft Teams
Audio sources in Microsoft Teams let you pick the exact microphone, speaker, and headphones you want to use for meetings. When your computer has more than two or three sound devices plugged in, this feature stops you from talking into the wrong microphone or listening through the wrong speakers.
You can switch your sound setup right before a meeting starts or even while a call runs in the background. Teams lets you test your new microphone and speakers instantly so people hear you clearly on the first try.
You can change audio sources before joining a meeting by selecting “Computer audio,” “Phone audio,” or “Room audio” on the pre-join screen, or during a meeting by clicking More actions (three dots), then Device settings, and selecting your desired speaker and microphone.
Setting Up Your Audio Before You Join
This screen provides an opportunity to confirm sound input and output devices are correctly selected. Testing audio here is like performing a sound check before a live event, ensuring clear communication.
Using Your Computer’s Sound
To change Teams audio source to your computer’s built-in speakers and microphone, select Computer audio on the pre-join screen before entering a meeting. This uses whatever default audio hardware you have already set up in Windows, ensuring your sound works right away without needing extra equipment.
Upon clicking to join a meeting, the pre-join screen appears.
- Look for the Audio section.
- It usually says Computer audio by default.
- If this is what you want, you are ready! Click Join now.

Switching to Your Phone’s Sound
To change Teams audio source to your phone when your computer mic fails, select Phone audio on the pre-join screen and choose Call me. Microsoft Teams will then call your phone directly, letting you use your mobile handset’s microphone and speaker for the call.
Here are a couple of methods for using your phone for audio:
- On the Teams screen before joining, go to the Audio section.
- Choose Phone audio.
- You will see two choices:
- Call me: Teams will call your phone. You need to type in your phone number. Then Teams will connect you to the meeting sound. Your phone will be your microphone and speaker.
- Dial in manually: This gives you a phone number, a Conference ID, and a toll-free number. You can call this number using your phone's dialer to join the meeting's audio.

Using a Meeting Room's Sound System
To change Teams audio source to a meeting room's sound system, choose Room audio on the pre-join screen and pick the correct room from the list. This connects your meeting directly to the conference room speakers and microphones so everyone in the room can participate clearly.
- On the screen before joining, find the Audio options.
- Choose Room audio.
- A list will show up with meeting rooms and their sound systems. Pick the right room.
- Click Join now.

Joining Without Any Sound
To change Teams audio source to completely off when you only want to watch or use text chat, select Don't use audio on the pre-join screen. This stops your computer from sending or receiving any sound, which is helpful in large meetings or quiet environments.
- On the screen before joining, under the Audio section, select Don't use audio.
Microsoft Teams meetings start with your microphone and speakers turned off. This setting is practical for large meetings where speaking is not required. It also helps if audio problems exist and you want to join silently first. You can turn on your sound later if needed.

Changing Audio While In a Meeting
To change Teams audio source while already inside a meeting, click the three dots in the meeting controls and open Device settings. From there, you can pick a new speaker or microphone from the dropdown menus to fix sound problems live without leaving the call.
- In the Teams meeting controls, click on More actions (it looks like three dots ...).
- Hover over Device settings.
- Under Audio devices, you will see options for your speaker and microphone.
- Click the dropdown menu next to Speaker to choose where you want to hear sound from.
- Click the dropdown menu next to Microphone to choose which microphone you want to use.
Teams will immediately begin using your newly selected audio devices.
