Why is the input microphone not being detected?

If your input microphone is not being detected, here are a few troubleshooting steps you can try:

1. Check the physical connection: Ensure that your microphone is properly connected to the correct port on your computer or device. If you're using a USB microphone, try connecting it to a different USB port.
