Z270-UD5 HDMI audio and thunderbolt

I finally got my computer able to boot after it just stopped working one day. Although it never worked the first time, I have been trying to get the audio to work via hdmi. I'm using a Samsung tv as my monitor and sound works great via any other source. I've added a few pics of some setting and if anyone can help me I would greatly appreciate it.

I am a total noobie with all of this. I don't even know if that config.list thing is in the right area...lol so please be patient as I try to...
