If your audio isn’t working during a Zoom call on your mobile device, there are several steps you can take to resolve the issue.
First, ensure that Zoom has permission to access your microphone. On iPhone, this can be checked in Settings > Privacy > Microphone, and on Android, go to Settings > Apps > Zoom > Permissions. Also, check your device’s volume settings by pressing the volume up button and confirm that Call via Device Audio is selected in Zoom’s audio options. If you’re using a Bluetooth device, try disconnecting and reconnecting it.
Make sure you have a stable internet connection, as a weak Wi-Fi or mobile data signal can cause audio issues. You might want to switch between Wi-Fi and mobile data to see if that helps.
If the issue persists, close and reopen the Zoom app, update it if necessary, or restart your device. As a last resort, uninstall and reinstall the app, and if none of these solutions work, contact Zoom support for further assistance.
