[IBM System x iDataPlex dx340 Server -[7832AC1]-, ATI R6xx HDMI, Digital Out, HDMI] No sound at all

[Dean Faber]

I did receive 3 small blurbs of sound which gave me the impression it might actually work then it just gave out altogether.

HDMI audio on AMD/ATI GPUs has been disabled by the upstream kernel developers as it causes blank screens on a lot of systems.

You can re-enable HDMI audio by adding radeon.audio=1 to your GRUB kernel boot options as described at https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot

[madbiologist (me-again)]

The upstream 3.13 kernel is currently under development. The radeon.audio=1 kernel boot option will no longer be necessary with this kernel. Instead, HDMI audio on ATI/AMD Radeon cards can be enabled and disabled on the fly by typing the following in a terminal window:

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

or

xrandr --output HDMI-0 --set audio off

If your HDMI port is numbered differently (type "xrandr" to check) - you might need to change HDMI-0 in the above command to HDMI-1 or HDMI-2.

The 3.13-rc2 kernel is currently available at http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how to install and uninstall it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds
