Public bug reported:
Intel NUC7i3BNH running Ubuntu MATE 16.10 plays no sound out on the HDMI port
to a Samsung UN32EH5300F
until after the power management puts the display to sleep at least once. Upon
waking the monitor sound is restored. Changing cables and ports did nothing,
and testing on a second UN32EH5300F had the same results. Oddly, testing on two
other TV's resulted in no problems with the audio.
