Make HDMI the Default Playback Device 

If you hear no sound through HDMI, it can be because your defaults are not set properly. You can often see that it’s easy to toggle between audio output devices on Windows, many times the default output device is the device speaker, and many times there is no audio output installed. You need to put HDMI as your default playback device to automatically toggle the output device back to the speakers after the connection is removed.

To change the default playback device:

  • Open Run by pressing the Windows Key + R.
  • To open the audio device settings, type mmsys.cpl and search.
Run mmsys
Run mmsys.cpl
  • Make sure that you are logged in through the Admin to make changes.
  • Go to the Playback tab and select the HDMI device option (often the option that does not say ‘speaker’ and normally is named after the desktop itself) and enable the device.
