Like RoberKH reported, HDMI audio does not work in 14.04 new
installation no matter what is done (adding radeon.audio=1 line to
/etc/default/grub or using xrandr) though ubuntu documentation states it
should work without any modification
(https://help.ubuntu.com/community/RadeonDriver#HDMI_Audio). Here are
the details:

$ uname -srm
Linux 3.13.0-32-generic x86_64

$ grep -Rn radeon.audio /etc/default/grub

$ xrandr --output HDMI-0 --set audio on

$ lspci -v | grep VGA

Title:
  [ATI HDMI] HDMI Audio Disabled by Default (since oneiric)

Status in “alsa-driver” package in Ubuntu:
  Fix Released

Bug description:
  Since kernel 3.0, upstream has disabled audio output for all ATI cards
  in the Radeon driver by default.

  === Workaround 1 ===

  Edit /etc/default/grub and change this line:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

  to this line

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

  Now run "sudo update-grub", then reboot your computer.

  === Or workaround 2 ===

  Install the proprietary Catalyst driver.

  ===

  There's no sound at all and videos playback in fast forward when
  outputting through the HDMI controller. This is a regression since it
  worked well in previous releases.
