sound - Ubuntu 16.04 HDMI Audio Not working, speaker-test works

I'm running kubuntu 16.04

I'm trying to get audio working through HDMI. I believe that I have to set the default card and device, but can not find how. I have check/tried:

1. I have check to make sure that the speaker are not muted using alsamixer.



2. In System Settings->Multimedia the default playback is set to "GF119 HDMI Controller Digital Stereo (HDMI)"


3. aplay -l shows output of:

**** List of PLAYBACK Hardware Devices ****

4. speaker-test -c 2 -r 48000 -D hw:1,7 produces white noise.


5. lspci -nn | grep '[04[80][13]]' produces:

6. Purging and reinstalling pulse-audio and alsa-base.

I'm not sure what else to add to be helpful.
