Since the upstream 3.13 kernel the radeon.audio=1 kernel boot option has not been 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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1003752 Title: [System Product Name, ATI R6xx HDMI, Digital Out, HDMI] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1003752/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
