Title:
  Only audio over HDMI in certain modes

Status in “alsa-driver” package in Ubuntu:
  New

Bug description:
  I've hooked up my computer (Ubuntu server 14.04 LTS) to my receiver
  which in turn is hooked up to my TV.

  The problem is that audio only works on certain modes. For instance,
  if I set the mode to 1080i60 using xrandr, audio works fine. The same
  goes for 1080p25. However, when I increase the framerate on the
  progressive scans on the 1920x1080 resolution the audio switches off.
  E.g. 1080p60 (the preferred mode) shows the video just fine,  but
  there's no audio.

  When the computer is directly connected to the TV I'm able to play
  audio despite using the preferred 1080p60 mode on the built-in TV
  speakers.
