Answer 1

A technician a mobile device that has no sound. A  technician should check If the volume is muted first.

Explanation:

• Improper audio settings in your computer can also cause your speakers plugged in but no sound. So you should check the following audio settings to fix your sound problem.
• An on-screen display appears with incall options. Tap the Mute icon. A microphone icon with a diagonal line through it.
• Just restart your phone as usual to refresh the device.
• Disable Bluetooth on your phone. Sometimes the Bluetooth feature would result in the speaker problem so here you are able to navigate to Settings> Bluetooth to switch off the feature to settle the problem.
• The earpiece may be damaged. This is because the dedicated noise canceling mic is damaged.
• You might have the sound muted or turned down low in the app. Check the media volume if nothing works out.
