Are you using the 4.04 or 4.13 kernel with Ubuntu 16.04?

4.13 which very recently replaced 4.10 in the Ubuntu HWE has definite
issues with some HDMI (5.1) configurations, causing me to revert to 4.04.

A bit of googling will show the issue.

Something changed in January, even 4.04 just sort of works.
'pavucontrol' shows my HDMI as unplugged but speaker test works and myth
does produce surround sound.

I don't think it is a mythtv fault.

Stereo works in both kernels.

On my main system with the NUC connected to an A/V receiver via HDMI I'm
running 4.13.0-32-generic x86_64

No issues with any audio at this point.

Kernel version:
mitchell@liva:~$ uname -r
4.4.0-109-generic

If the suggestion is to remove pulseaudio anyone have instructions? I
tried just issuing sudo apt-get remove pulseaudio but that didnt seem to
make a difference.
