Hi,

I have normal sound on my laptop. Suddenly;  I no longer have  sound on my TV when I have my laptop connected to it via HDMI. It was working and then one day it stopped.

 

THings I;ve tried. Showing disabled devices.

Updating drivers.

factory restore. 

I believe I may be missing the Intel HDMI sound driver for the graphics card. I've tried to install and run every available graphics card and sound card driver on the Support page for the laptop but it hasn't resolved the issue.
