Microphone Issues

Good afternoon everyone. Can you assist? I am on a 2017 HP Laptop. I have a problem with the microphone during a ZOOM meeting. I can log in with no issue. However, I can see and hear everyone, but they cannot hear me. The video is working fine. I have went through testing the microphone, but it's not recording or repeating what I say. I've upgraded all of my drivers and systems with HP this morning, and they say it should be working. Again, it's still not working. Any suggestions?
