The TV being used is an older Samsung model.

This issue is still present for me. Sound works perfectly well with windows, so I am 99.9% certain the issue is something in ubuntu itself.

Ran MOC with a looping sound file and then opened Pulseaudio Volume Control.

Under output devices, with the default device selected, it plays perfectly well. The HDMI shows up correctly under audio devices [HDMI/DisplayPort 2 (plugged in)], but when selected no sound emerges.

The output bar is showing that sound is being routed through that port, but nothing emerges. Option selected under advanced is just PCM (not sure what these do but it's best to report everything).
