    Support for SI/TN and newer hardware was added in 3.12. Additionally, with 3.12 you no longer need to boot with radeon.audio=1. You can enable/disable audio on the fly with xrandr. E.g., xrandr --output HDMI-0 --set audio auto
    Really? I did some tests with 3.12 and I thought it didn't work because I didn't know of the new xrandr option.

    Any chance to fix QT's raster engine? SI is starting to be fast and supports lots of features, it's a pity being not able to use it

      Are you sure you were using a recent 3.12 kernel? Make sure your kernel has:

          I'm using 3.12-rc1 from the ubuntu kernel ppa, I suppose it should be there, though I haven't checked.

          Edit: I checked that the patch was merged 3-4 days before rc1 was tagged so I suppose my kernel must have it, too.

          I only get:
          ~$ xrandr --output HDMI-0 --set audio enable
          X Error of failed request: BadName (named color or font does not exist)
          Major opcode of failed request: 140 (RANDR)
          Minor opcode of failed request: 11 (RRQueryOutputProperty)
          Serial number of failed request: 37
          Current serial number in output stream: 37

          If I write "auto", "on", etc. it's still the same story.
          As I said, with radeon.audio=1 works, which is already good enough for me until ubuntu sorts itself out.

            What output do you get for:
            Code:
            cat /var/log/Xorg.0.log |grep "X Server" && xrandr -v

              X.Org X Server 1.13.4
              xrandr program version 1.3.5
              Server reports RandR version 1.4


              So is my xrandr version too old? That would be simple explanation, I guess.
              Btw, thanks for your help!

                With v2.0 specs released. Anssi could implement Bitstream Audio within minutes:

                Thanks all involved.
