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:

• Have you made any recent changes to your computer?
• 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.
