Did the other participants have the same situation?
If you press it, can you hear the meeting sound normally?
There can be many reasons for this problem, such as:
- The mute option that the device itself has been turned on unexpectedly.
- The meeting organizer mutes the attendees and sets a PIN.
To find out who muted you or all attendees, you can view the meeting chat or meeting details in Teams. You can also ask the meeting organizer or other participants if they need to manually turn on the meeting sound.
Hope this helps! Moreover, if the above is not your scenario or I have misunderstood anything, please correct me and provide us with detailed information about the issue including the screenshot so that we can better understand to further assist you.
