Let’s see all these fixes in detail.

1] Check the default audio device

It is important that the audio device you want to use is set as the default device on Windows 11/10. If the audio device is not set as the default device, Windows will not use it and you will get the sound output from the built-in speaker of your laptop.

Go through the following instructions:

Open Windows 11/10 Settings.
Go to “System > Sound.”
Select the right audio device under the Choose where to play sound section.

You can also control the volume of your audio device by moving the slider.

2] Make sure that the audio device is enabled

Some users reported that their TV speaker was not shown in Windows Settings so they could select it. Such a problem occurs when the connected audio device is disabled. You can check this in Sound Settings. Follow the steps provided below:

Open the Control Panel.
Go to “Hardware and Sound > Sound” if the View by mode is set to Category. If the View by mode is set to Small or Large icons, the Sound option is available on the Control Panel Home.
Your TV speaker should show a green tick under the Playback tab. If not, it is disabled.
If your TV speaker is disabled, right-click on it and select Enable.
Click OK.

This should fix the problem.

3] Check the Volume Mixer setting

After connecting your computer to your TV via an HDMI cable, if you are not getting sound output from your TV in some particular applications, check the Volume Mixer settings. The following instructions will guide you on this:

Open Windows 11/10 Settings.
