      Another step in the right direction, but still no alternative for modern GPUs. We're getting there though.

      Until then, I'll stick to NVIDIA on my desktop and to AMD on my laptop.

            This is great. I really was literally reading up on HDMI audio support on Radeons under Linux when this popped up on my feed reader.

                As far as i know, this is the first time since late 2008 that i think docs have been released by the ATI guys. The shader ISA stuff was done by the AMD GPGPU group, which at least in 2008, was a newly formed team and not some old ATI haunt. Does anyone know how this doc came to be?

                Well done anyway though. Now where are all those other docs that we should've had in the past 5 years ;p

                    Unless you're hitting one of the bugs you can enable it yourself with radeon.audio=1 though I agree it should be on by default

                            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

                              I'm assuming "--set audio" takes on/off/auto as arguments? With defaulting to auto, i would hope. So the only thing I should have to do is plug in my HDMI cable and point a stream from Pulseaudio at the HDMI connection and I should get output on the other end of the connection?

                              Side question, is xrandr persistent? I know screen settings werent really persistent, but other settings? Like if i wanted to turn HDMI audio off with

                              Code:
                               xrandr --output HDMI-0 --set audio off
                              would that persist across reboots?
