If you're facing audio issues during your Zoom call, here's a brief guide to help you. Make sure your microphone isn't muted. Look for the mute icon in the meeting controls and tap to unmute if necessary. Likewise, ensure your device's audio is connected to Zoom. If you see the 'Join Audio' icon, tap it and choose 'Call Over Internet'. Lastly, consider using earphones equipped with a microphone for better audio quality.
