I have had a gaming set up with a big screen TV for 2 years now with no issues.
Recently, I've had issues with my graphics card rendering so today I had to uninstall and reinstall with the newest version of the Radeon RX 580 drivers and it's clear from all my troubleshooting that AMD doesn't even support HDMI Audio anymore. That means my 4k awesome TV now can't use their graphics card and play audio through it. I do not have AMD Audio Drivers and they are not listed in driver install or available to download.
I looked everywhere in my computer for the drivers and it shows nothing installed. What's even more ridiculous is the installation page and all possible interfaces for the driver have absolutely no mention of audio/sound or audio settings and the amd website has no listings for audio or sound in all of its worthless help topics.
How exactly are you running a business and ignoring a major part of your product?!?! If you don't support something as basic as audio through an HDMI cable, then you shouldn't be selling graphics cards.
