The device is working.  From your alsa-info.sh output:

!!Aplay/Arecord output
!!------------

[ ... ]

card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

You should be able to use hw:0,3 to output to the HDMI.

aplay -L does not list it because the device is just not defined in
your alsa-lib.  Probably alsa-lib 1.0.18a would list it.
