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 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/567649 Title: No sounds output through HDMI interface Status in “alsa-driver” package in Ubuntu: New Bug description: Binary package hint: pulseaudio No sound through the HDMI port or the headphones. If you plug the headphones in no sound through the speakers and no sound though the headphones.
