Ok, so the option for my HDMI sound or external sound or whatever, is no longer in my sound setting in control panel. How do I get it back in there or re add it? I had hit disable on it the other day and it wasn't there but I hit properties and it was, now its not.
Ok so I had this same problem. And so I went back into Control Panel, Hardware and Sound, and then to Sound. Right click on one of the devices that is displayed, such as Speakers and headphones and make sure theres a check mark next to Show Disabled Devices. It should appear if it had been disabled prior.
