Hdmi sound not working

Hi Peter,

One possible reason why the HDMI sound does not work is due to the conflicts with the playback settings. For us to help you make the HDMI sound to work, we suggest that you answer the following questions for further research:

• What is the current build and version of your Windows 10?
• Have you tried to download and install the most updated sound and display driver of your computer?

Meanwhile, we suggest that you perform the steps on this
article as our initial troubleshooting and see if there will be any changes on the HDMI sound.

We'll be waiting for your response.

 

HDMI Audio in NOT working

Hi Dustin,

We appreciate your interest in Windows 10.

Please try the methods below and check if it works.

Method 1:

I would suggest you to follow the steps and check.

Let’s first check if “HDMI Output” is selected as the default device.

Follow these steps:

• Click Start and select
  Control Panel.
• On the right hand side of the screen, under
  View by: click the drop-down icon and select Large icons.
• Click Sound.
• If you do not have the
  HDMI Output listed under “Playback” tab, right click in the
  playback window and select Show Disabled Device and
  Show Disconnected Device.
• If the HDMI Output option appears, right-click
  HDMI Output and select Default
  Device.

Now the audio must be playing on HDMI. If the issue persist, follow the below method.

HDMI Port Stopped Working

I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?
