Microsoft Teams is widely used for virtual meetings, but a common problem is when the microphone doesn’t work—either no one can hear you, or Teams doesn’t detect your microphone at all.
In this article, we’ll cover the causes of this issue and provide step-by-step solutions.

📌 Common Causes
1️⃣ Device Settings or Hardware Issue

- Physical issues with the microphone or headset.
2️⃣ Teams Permissions Missing

6️⃣ Corporate Policies or Admin Restrictions
- Group policies or Teams settings may disable audio devices.
