Up until a week ago I have been using my television as my second display and occasionally play netflix shows and use the television speakers for audio. Some time last week my television was no longer showing as an option for an audio device. I have it showing all disabled and disconnected devices it's not there. It's not anywhere on device manager, or in the playback devices. The only place I can get it to show up is if I "show hidden devices" in device manager I can see EW37S5KW (AMD High Definition Audio Device) which is what the television previously showed as when connected. I click properties and it says the device is not connected, but I have a display showing.
My first hint at what might be causing the issue came today. I decided I would upgrade my display drivers to see if that would fix the issue. After the drivers were finished installing, low in behold, I got the noise your computer makes when connecting something to the USB, and my tv was playing sound. However once I restarted the computer to complete the installation process, the TV disappeared as an audio option again. This leads me to believe there is something happening during start up that is either rolling back the audio drivers, or using a different on completely? I'm not entirely sure and could use some help.
Radeon r9 290 w/ updated drivers.
TV is a westinghouse, and the HDMI cable is in working order.
Motherboard is Asrock z97 Pro4
Thank you in advance for any help!
