6 years ago Question, What video card are you using? that can be the answer right there. I had the same issue and i replaced the video card after looking at this supported graphics cards page http://wiki.openelec.tv/index.php/Supported_Graphics_Cards I was using an old 256MB ATI Radeon HD 3450 card with hdmi out. But saw that HD audio was NOT supported.(audio out was PCM) then I found a GTX 650 2gb card for $20.00 on Offerup ( by the way im running openelec 8.04 on a Dell Studio Desktop 2.3GHz Intel Core 2 Quad Q8200 6GB 800MHz DDR2 SDRAM. But anyway Forget about looking to install drivers....Change the card
The HP Compaq 8000 Elite (https://support.hp.com/ca-en/product/hp-compaq-8000-elite-small-form-factor-pc/4065894/drivers) doesn't show HDMI audio in the audio settings.
I am brand new to OpenELEC but have used Xbuntu in the past with great success. How do I update the video drivers, or Wifi Drivers in OpenELEC? I'm hoping that this will allow me to use the HDMI output.
Just a note Im using DP output on this device and the manual does say the DP support audio.
