No HDTV audio order number: 116-5780627-6459404 No audio from HDMI port to HDTV. Can get audio from laptop or portable speaker thru 1/8" audio output. Can you help?

Hi Cheryl,

Thanks for reaching out to us, I’d be more than happy to assist you with your Plugable USB3-HDMI-DVI display adapter and resolving the issue you are having with the audio.

When the USB3-HDMI-DVI display adapter is set up and connected to the laptop and TV, can you go into the ‘Sound’ panel and verify that the default audio playback device is set to the USB3-HDMI-DVI display adapter.…

If not set as the default audio device can you please change it so that the Plugable device is the default playback device.

Does this help at all?
