When you plug a Lightning audio device such as a headphone or headset into the hub/dock’s Lightning audio port, but no sound is heard from the audio device, the issue may be caused by the connected laptop, audio device, or hub/dock. 

Here are some troubleshooting tips that may help you locate and resolve the problem.

For laptops:

• Make sure you set the audio output to the correct mode on your laptop:

macOS: Open System Preference > Sound > Output > External headphone.

Windows: Left-click the sound icon in the taskbar > Select the device in the drop-down menu > Choose the connected headset.

• Try this device with a different laptop to see if the issue persists.

For Lightning audio devices:

• Confirm whether the audio device can work normally without the hub/dock.
• Try a different Lightning audio device.

For hubs/docks:

• Try using a different hub/dock with a Lightning audio port to see if the audio device can work well.
