Hi @Jasmine
Thank you for sharing the details of your experience during the Teams meeting. Let me explain why this can happen and outline steps to prevent it in the future.
When you mute your microphone in the Teams desktop app, the mute applies only to the device selected in Teams at that moment. If multiple microphones are connected, such as your laptop mic and a webcam mic, the other device may remain active. In your case, docking the laptop likely changed the default audio input to the webcam microphone. As a result, Teams may have detected audio activity on that device and automatically switched or unmuted it.
Additionally, Teams includes a feature that can unmute when it detects speech. If the webcam mic was active, playing audio from your phone could have been interpreted as speech, causing Teams to override the mute status.
To prevent this behavior, please try the following steps:
1/ Set a fixed microphone in Teams
- Open Teams, go to Settings > Devices, and select the exact microphone you want to use.
- Avoid leaving it on “Default,” as Windows can change the default device when docking.
2/ Check Windows sound settings
- Before joining a meeting, open Windows Sound Settings and confirm the correct input device is selected.
- You can also disable unused microphones, such as the webcam mic, to avoid conflicts.
3/ Verify after docking
Each time you dock your laptop, confirm the microphone setting in Teams before starting the meeting. Docking often resets audio routing.
4/ Consider using a dedicated headset
A single audio device, such as a USB headset, ensures consistent mute behavior and reduces conflicts between multiple microphones.
5/ Submit your suggestion to Microsoft:
