For Ubuntu 13.10 "Saucy Salamander" and earlier, HDMI audio on ATI/AMD Radeon cards is disabled by default 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 boot options as described at https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot Beginning with the upstream 3.13 kernel, the radeon.audio=1 kernel boot option will no longer be necessary. 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. Ubuntu 14.04 "Trusty Tahr" is based on the 3.13 kernel. -- 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/778045 Title: [VPCEB4S1R, ATI R6xx HDMI, Digital Out, HDMI] No sound at all Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: No sound ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: alsa-base 1.0.24+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 2.6.38-9.43-generic 2.6.38.4 Uname: Linux 2.6.38-9-generic x86_64 NonfreeKernelModules: fglrx AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
