    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 thro...

    tl;dr: You need to load the radeon module with "radeon.audio=1".
    I already did that, and still got no audio. Judging from the forum threads I've found about it, this is the standard experience with Fusion systems (followed immediately by installing Catalyst or switching to a non-HDMI audio output).

      We'll see how it works on mine as well... I've got an A6-3xxx at home in my HTPC, and I've been using analog audio + OSS driver because my HDMI wasn't outputting anything. I'll try the kernel parameter sometime this weekend and see if it helps.

        openSUSE uses zypper not yum

        openSUSE has that, it's called 'zypper dup'.

            Better ATI support than in 11.10 ?

            In Ubuntu 11.10 (and Linux Mint 12 - Ubuntu-based), I never had much luck with my ATI chip. It's a FirePro m7740 chip, which appears to be a one-of-a-kind that AMD made for Dell's mobile workstations.

            Anyway, with the aforementioned versions of Linux, the open-source driver would garble the menus in Gnome 3 and Cinnamon. But installing the closed-source Catalyst driver was a nightmare that I haven't yet licked, either.

            Any idea if this situation will get any better with Ubuntu 12.04?

              What to expect from ATI Radeon HD6900 with Kubuntu 12.04?

              What to expect from ATI Radeon HD6900 with Kubuntu 12.04?

              Will the open source driver work, or should one install catalyst? automatic Fan control, clock throttling and HD video playback (x264) work with the open source diver as well? Has the open source driver other advantages?
