    What would I need to write in place of Radeon?
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"
    Nvidia is different. I don't know if fermi still has "spdif" crossover cable, as previous generation, but you may want to look it up.
    Otherwise, its wrong thread to ask anyway.

      isnt it much simpler to use nv binary drivers?

        Thanks anyways. I've had trouble getting HDMI sound to work on 11.04, 11.10 and over two laptops. Never mind, I'll keep searching!

        Thanks again.

          it is possible that you need to change one line in your default.pa - add the correct sink you found out which is working using "speaker-test -D hw:0,x -c2" - be sure all 4 possible spdif channels are unmuted (OO) with alsamixer. use nv binary driver. the x is the device number you get with "aplay -l". for onboard the card number is always 0, but of course not for a desktop system with dedicated gfx card.

            radeon.audio=1 is for the open-source driver, the proprietary driver doesn't use it. With nvidia you still need the proprietary driver for HDMI audio - Nouveau support for it won't come before the 3.2 or 3.3 kernel.
            Intel is a different matter. The HDMI audio is a codec chip connected to the onboard sound controller (or even integrated into it?), and the only thing that relates it to the graphics is that it happens to use the same HDMI connection for its output.

              No Sound

              Hi,
              My first time on this forum.
              I am having a similar problem - although I have an Intel i5 processor and HD 5700 series card. Everything was working fine in Kubuntu 11.04 but after upgrade to 11.10 no sound at all. Adding radeon.audio=1 to grub has made no difference.
              Any suggestions as to where else I should look?

              Thanks

                  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"
                  now i do have killed the borg catalyst

                  i also upgrade to 3.1 linux kernel and i also upgrade to oibaf radeon driver PPA

                  but

                  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

                  don't work? no sound...

                    After an edit to /etc/default/grub, you have to run sudo update-grub2 (or sudo update-grub).
