sound on zoom - participant unable to hear me

Did you manage to get sound from participant . I have the same problem trying to solve this problem. Thank You Joanne 

Why can't my participants hear me on Zoom?
Increase the volume on your mobile device using the volume buttons or notification panel. Even if the speaker is turned on in Zoom, your device's volume might be set to mute or vibrate only. Try using earphones or a headset with a built-in microphone. Restart your mobile device.
