Hi Craig,

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

Method 2:

I suggest you to update the HDMI drivers. Refer the below link to check how to update drivers in Windows 10.
