no audio on extended display

Is your computer’s Operating System updated?

How about your Audio drivers, can you check if it is updated and can support HDMI audio output?

If your answer to those questions are yes, then you can check these steps to setup audio for your extended display:

• Connect your laptop to the extended display using the HDMI cable.
• On the lower right side of your task bar, right click on the Audio icon.
• Select Playback device
• If you don’t see your extended display (T.V) you can right click on a blank space on the Playback tab and select Show Disabled Devices and Show Disconnected Devices.
• One your extended display (T.V) is showing, please check if it is enable.
• Then Select OK.

Do a test and check if the audio is now playing on the extended display, if issue still persists, try to restart your computer without removing the HDMI for both devices.

Let us know how it goes.
