Hi Sabouba , I'm Sergio, it's a pleasure to help you.
You can try to:
- Check for pending operative system and Teams updates.
- Remove all bluethoot headset from the devices list and connect it again to the computer.
- Make a test call.
To make a test call, select your profile picture, then choose Settings > Devices. Then select Make a test call under Audio devices.
In a test call, you'll see how your mic, speaker, and camera are working. Follow the instructions from Test Call Bot and record a short message. The message will play back for you. After that, you'll get a summary of the test call, and you can go to your device settings to make changes.
- You might need to change one of your privacy settings. Here's how to check:
a. Open Settings
b. Under Privacy, select go to all items related to the audio.
c. Make sure the setting access for this device is turned On
d. Close all apps and restart your device
I hope that you can solve the problem, please let me know about the result.
Greetings.
