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.

Further, by running a Google under keywords "linux "hdmi" sound Sunrise Point-H HD Audio" - I found a number of articles which may be of assistance, but I have not the time to go through them all at the moment. Putting the quotes around hdmi restricts the search to showing hdmi answers.
See how you go with the above first, and we'll hope that someone better-versed in audio bails us (me) out

In the sound settings, in Output tab the built-in-audio was set to Analog Stereo Duplex. Change the mode to HDMI output Stereo. Note that you must be connected to an external monitor through a HDMI cable to see HDMI output option. ... Click on it and enjoy the sound of music
It has now been nearly four years since the OP last responded, but I had the same issue just now, so naturally I searched the web for the answer. I happened upon Sam's post here, which has solved the issue for me. The OP may have lost interest in the thread a long time ago, but you never know when a forum post will turn up in the search results of someone having the same issue!
