2️⃣ Select the Correct Microphone in Teams Settings

Often, Teams picks the wrong device. Here's how to fix:

2. Under Speaker and Microphone, use the dropdown to select your actual mic (e.g., headset or built-in).

Outdated drivers cause most hardware glitches. On Windows:

For deeper scans, use Windows Sound settings > Troubleshoot. On Mac, check Software Update. This resolves driver conflicts in recent updates.
