This bug still affects me and no fix or workaround in sight. That is
quite annoying. Do you have any suggestions?

  HDMI audio device doesn’t appear in sound config

Status in “alsa-driver” package in Ubuntu:

Bug description:
  If I plug in a audio capable HDMI monitor, I used to change the audio output device to HDMI using the regular audio settings dialogue. For some weeks, this device has disappeared. I can only chose the internal speakers for audio output.
  I’m not quite sure but this bug could have appeared after dist-upgrading to 14.04.
  Which additional information do you need to fix this bug?
