Fix: No Audio Device Found

1. Click your profile icon in Teams → Settings → Devices.
2. Under Audio devices, select the correct microphone and speakers.
3. If no devices appear, check your system settings:
   • Windows: Settings → System → Sound → verify input/output devices.
   • Mac: System Preferences → Sound → check Input and Output.
4. Reconnect USB or Bluetooth devices if needed.
   ✅ Teams should now detect your audio device.

Fix: Echo During Calls

• Use headphones instead of open speakers (open speakers cause echo feedback).
• Ask other participants to check their audio — echo is usually caused by one person’s setup.
• In Teams → Settings → Devices, enable Noise Suppression and Echo Cancellation.
