I've been trying to get linux to work with my HDMI sound to no avail. I tried Ubuntu 18.04 and 18.10, Fedora, and openSUSE. I've read a bunch or articles and tried many things like alsa force-reload, pulseaudio --kill, and all that jazz. Maybe it's my sound card? I'm reinstalling Ubuntu 18.04 so if you have any suggestions for getting HDMI sound to work on that it would be much appreciated! Not even sure what my sound card is so help on checking that would be awesome too. I know my graphics card is a Nvidia GTX1070, but does that mean my sound card is Nvidia too? Sorry, I'm pretty new to Linux and haven't had to worry about these kind of things with Windows. Thanks.
