Most time microphone does not work on Bluetooth devices while calling

Issues with Bluetooth devices during calls, where your microphone doesn't transmit your voice, can occur due to several reasons. Here are some troubleshooting steps you can try:

1. Ensure that the app you're using for calls (like Skype, Zoom, or the default phone app) has permission to access the microphone on your device.
2. Turn off Bluetooth on your device, wait for a few seconds, and then turn it back on. Sometimes, a simple reset can solve connectivity issues.
3. Disconnect your AirPods or Bluetooth device from your phone/computer and then reconnect them. Sometimes, re-establishing the connection can fix the problem.
4. Low battery levels on your Bluetooth device might affect its performance. Charge the device fully and try again.
5. Ensure that your Bluetooth device is compatible with the device you're using for calls. Sometimes, certain devices may have compatibility issues.
6. If none of the above steps work, contact the manufacturer's support for your Bluetooth device. They might have specific troubleshooting steps or be aware of any known issues.

If none of these steps resolve the issue, there might be a hardware problem with either the Bluetooth device or your computer. In such cases, further technical assistance or a visit to a service center might be necessary.
