How to Fix No Sound Through HDMI in Windows 10

Now that you know what’s most likely to cause hdmi sound not working on tv windows 10, here are some step-by-step solutions to try:

To check the sound settings:

Go to the Windows Sound settings (Right click speaker icon > Sound Settings)
Under ‘Output’, check if the HDMI device is set as default. If not, select it and set it as default.
Under the HDMI device properties, double check that the sound format is supported by your display (for example – stereo, 5.1 surround etc.)
Click Apply/Ok to save the changes.

This will configure Windows to send sound through the HDMI connection. Restart any audio/video applications and see if HDMI audio starts working.

2. Confirm Sound Output Settings

Windows 10 hdmi audio not working problems often occur when your audio output is inadvertently set to use speakers or another device rather than your HDMI connection.

To confirm Windows 10 is set to output sound over HDMI:

Right-click the speaker icon in your taskbar and select Sounds.
On the Playback tab, look for your HDMI device and make sure it’s selected as the Default Device. If not, select it and click Set Default.
Also check the Playback tab while playing media to confirm the green volume bar raises when sound is played through your HDMI device.

This ensures Windows is directing audio through your HDMI connection rather than another audio device like your computer’s built-in speakers.

3. Update or Reinstall Audio Drivers

Updating your Windows HDMI audio drivers may resolve sound issues after recent Windows updates, app installations, or hardware changes. Here’s how:

Expand the Sound, video and game controllers list.
Right-click your audio device like High Definition Audio Device and select Update driver.
In the update wizard, select Search automatically for updated driver software to allow Windows to install the latest driver.

If updating does not work, uninstall the device driver completely and restart your PC. Windows will automatically reinstall the driver when your PC starts again.

You can also visit your device manufacturer’s website to download the latest HDMI audio drivers for your model. Install these drivers manually to fix driver issues.

4.Try an Alternate HDMI Audio Format

Certain HDMI display devices like TVs work best with specific HDMI audio formats. If your Windows PC is set to an HDMI audio format your display doesn’t support, you’ll get no sound playing through hdmi.

To rule this out, you can try forcing your Windows 10 PC to use a different HDMI audio format:

Right click the speaker icon and choose Sounds.
On the Playback tab, select your HDMI device and click Configure.
Switch to the Advanced tab and use the drop-down menus to change the audio format. For example, try changing the default format from DTS Audio to Dolby Digital.

Windows 10 hdmi audio not working problems can occur if your PC fails to detect your HDMI display after connection. Here’s how to quickly fix detection issues:

On the Playback tab, right-click your HDMI output device and select Properties.

Reboot after uninstalling unnecessary audio utilities. Audio should now play normally over your HDMI connection. You can reinstall the programs again if removing them didn’t resolve the no sound issue.

10. Check Display Adapter Settings

Lastly, another setting that can prevent proper HDMI functionality is disabling digital audio support in your Display Adapter properties:

Right-click your desktop and choose Nvidia Control Panel or AMD Radeon Settings.
Go to the Sound or Audio settings. Make sure audio over HDMI is enabled.
Also, confirm that audio pass-through and bitstream options are configured correctly. Enable these settings for multi-channel audio.
Try toggling between stereo uncompressed and bitstream output to test which one works.

Verifying the audio transmission settings for your graphics card and display adapter drivers can resolve HDMI sound issues in Windows 10.

This ensures your display adapter is configured correctly to pass HDMI audio from your PC to your connected TV, receiver, or monitor.
