Troubleshooting Steps for No Monitor Audio via HDMI

Follow these steps to troubleshoot and fix monitor speakers not working with HDMI:

1. Check HDMI cable connection.

The most common reason for no sound on the monitor with the HDMI cable is a loose HDMI connection.

Make sure the HDMI cable is firmly plugged into the HDMI port on both the monitor and computer or other source devices like a streaming stick.
Try connecting the cable to a different HDMI port if available.
Inspect the HDMI cable for any damage or bent pins. Test with a different HDMI cable that you know works properly.
Use a high-speed HDMI cable that supports 1080p resolution at a minimum.
Ensure the HDMI source and monitor are not too far apart. HDMI cables longer than 10 feet can cause issues.

2. Set Monitor to Correct HDMI Input Source

If the HDMI connection is fine, next check that the monitor input source is set correctly:

On the monitor, access the Input Source options from the monitor menu using the buttons or remote if available.
Select the input that corresponds to the HDMI port you connected the HDMI cable to. This is commonly labelled as HDMI1, HDMI2, HDMI3, etc.
The monitor screen should now show the display from the HDMI source device.

3. Enable Audio Output to HDMI Device

Once you confirm video output is working from the HDMI source, next enable HDMI audio:

On Windows:

Go to Start > Settings > System > Sound.
Under “Choose your output device,” check if HDMI or your monitor brand is listed. If not, select it from the dropdown.
Open the Sound Control Panel from the right pane and go to the Playback tab. Enable the HDMI or monitor audio device. Set it as the default device.
Right-click the HDMI device and select Properties. Go to Supported Formats and make sure all audio formats are enabled.

On Mac:

Go to Apple menu > System Preferences > Sound.
On the Output tab, select your HDMI-connected monitor or TV.
You can also click the HDMI device and select Use This Device for Sound.

On streaming devices:

Access audio settings from the Settings menu.
Set HDMI or external speakers as the audio output device instead of the TV or internal speakers.

4. Update or Reinstall Audio Drivers

HDMI monitor no sound from speakers can also occur due to corrupt, outdated, or missing audio drivers.

On Windows, open Device Manager and expand the Sound, video, and game controllers list.
Right-click on your audio device, like Realtek HD Audio, and select “Update driver.”
If updating does not fix the issue, uninstall the device, reboot your PC, and reinstall the latest audio drivers from your motherboard or hardware manufacturer’s website.
On Mac, install the latest versions of macOS and your monitor brand software, like OnScreen Control from LG, to get updated drivers.

5. Adjust Incorrect Monitor Audio Settings

If drivers are up-to-date, check for incorrect monitor audio configurations:

Access the monitor menu using the buttons or remote and locate audio settings.
Make sure the monitor speakers are enabled and not muted or set to zero volume.
For HDMI audio, the monitor sound option should be set to HDMI, not Line-in, DisplayPort, or other modes.
Try resetting the monitor audio settings to default if the configurations seem wrong.

6. Switch to Different Hardware

No sound on the monitor’s HDMI after trying the above steps may point to hardware-related problems:

Connect the monitor via HDMI to another source like a streaming stick, game console, or Blu-ray player. See if you get audio from them.
Try a different HDMI cable and port on both the monitor and source device.
Test the monitor with another computer or laptop.
Use an external speaker system connected via audio out from the monitor.
If the monitor works fine with other devices, the problem lies with the original HDMI source, like your PC.
For PC issues, connect its HDMI audio to a different monitor or TV. Also try using a USB sound card or HDMI audio extractor as a workaround.
If nothing works, it likely indicates a hardware fault with the monitor speakers or HDMI ports. Contact the manufacturer for repair or replacement options.
