I get no audio through the HDMI cable

I get no audio from my smart TV when I hook my computer up to the TV via HDMI or Thunderbolt. In Playback I only have the Realtec Speakers showing. Also Bang & Olefsen Audio Control. The video works fine.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

1. Connect the HDMI cable to your computer and to your output device.

2. In Windows, search for and open Control Panel.

3. Click Sound, and then click the Playback tab.

4. The Sound window opens. On the Playback tab, select Speaker/Headphone or Speakers and Headphones, and then click Set Default.

   NOTE: Use Default Devices for audio output devices such as headphones or speakers. Use Default Communication Device for making and receiving phone calls.

   

5. Select the output device connected with the HDMI cable, and then click Set Default.

   

6. Right-click the output device connected with the HDMI cable, and then select Show Disconnected Devices. The HDMI cable must be connected when it is configured.

   

7. To view all the available sound devices, right-click any device shown in the Sound window and select the Show Disabled Device and Show Disconnected Devices options.

Hope this helps! Keep me posted for further assistance.
