thanks for sharing your tips!
It seems there's a long way before we'll get it work from scratch...

Title:
  HDMI sound output not detected / NVIDIA optimus laptop

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  not sure if this is an alsa or nvidia/nouveau bug.
  HDMI audio output doesn't appear in sound settings output panel.
  Audio works well on internal speakers, but it seems there is no way to make it output to hdmi...

  The laptop has optimus NVIDIA+Intel.
  The behaviour is the same with nouveau or nvidia proprietary driver.

  Please let me know if further testing is required
