Managing sound and video settings during Teams meetings and calls for optimal communication
Select the laptop’s microphone—not its speaker—as the Teams input device, then leave the meeting on the iPhone without choosing Leave on all my devices.
Fix the laptop microphone
- In the Teams meeting, verify the Mic button does not have a line through it.
- Select the arrow beside Mic → More audio settings.
- Under Microphone, select the laptop’s built-in microphone or the microphone on the headset you intend to use.
- Speak and check whether the input indicator responds.
- Outside a meeting, open Teams → Settings and more (…) → Settings → Devices:
- Select the same microphone.
- Select Make a test call and record a short message. Teams should play it back. This test is unavailable in Teams on the web. ^1^
Speaker volume only controls what you hear; it does not control whether others hear your microphone.
Disconnect the iPhone
If Teams is open with the same account on both devices, the iPhone can join as a second device. Teams normally switches off the second device’s microphone and speaker to prevent echo. ^2^
- On the iPhone meeting screen, tap Leave to remove only the phone.
- Do not select Leave on all my devices, because that also ends the meeting on the laptop.
- If the meeting was transferred to the iPhone and the laptop was removed, open the meeting on the laptop, select Join, and choose the laptop’s audio settings before joining again.
For future meetings, if the iPhone displays Join call, do not select Add this device or Transfer to this device unless you deliberately want the phone connected.
If the microphone still does not work
Check whether Windows can hear it:
- Open Start → Settings → System → Sound.
- Under Input, select the intended microphone.
- Run Microphone test:
- Windows 11: select Start test, speak, select Stop test, and play the sample.
- Windows 10: speak and watch the Test your microphone indicator.
- If Windows detects the mic but Teams does not, open:
- Windows 11: Settings → Privacy & security → Microphone
- Windows 10: Settings → Privacy → Microphone
- Turn on Microphone access, Let apps access your microphone, and Let desktop apps access your microphone. Ensure Teams access is enabled, then close Teams and reopen it. ^3^
If Windows shows no microphone response at all, run the recording/input audio troubleshooter from Settings → System → Sound on Windows 11, or Settings → Update & Security → Troubleshoot → Additional troubleshooters → Recording Audio on Windows 10. ^3^
