My phone won't pick up audio?

[Android Central Question]

I'm confused as to why my phone won't pick up audio. Whenever I take a video and replay it the only sound I hear is a slight static noise and when people call me or I call them they can't hear me. How do I fix this?

Look in the tiny hole for debris. Carefully clean the hole and try again. If that doesn't work you may have software or hardware issues.
My first guess would be debris in the mike hole.. Pocket lint etc... Be very gentle lest you pierce something making your issue permanent!
