I'm running on a new Intel NUC d54250wyk.

When I plug in an HDMI or DisplayPort display which supports audio, I see the
audio device reported as present in all the expected places - PulseAudio, ALSA,
EDID output in dmesg, etc.

But when I try and play any noise, I simply don't hear anything.

These display have worked correctly with audio on an older NUC DC3217IYE, and
the analog audio out on the new NUC works fine.
