    Phoronix: SteamOS 2.115 Switches From AMDGPU-PRO To AMDGPU+RadeonSI

          Until AMD's Mesa driver supports audio over HDMI, I wouldn't make this change for a home console OS...

            I might be totally wrong, but I think the problem is RadeonSI but not Mesa. Either way, I agree with what you wrote - if the hybrid proprietary driver has audio over HDMI and the open driver with Mesa doesn't, then a switch doesn't make sense.

            The hybrid proprietary driver violates the spirit of free software, but if you're running Steam then you're already proven yourself not to be a free software fanatic.

                I, too, have made the switch this week (again, but for good this time!). Michael's recent benchmarks made me a convert.

                Only thing that had kept me on AMDGPU-PRO was FreeSync support and HDMI Audio (which I no longer needed). Vulkan support was better on AMDGPU-PRO but not a dealbreaker for me and open-source is catching up. I can hold off on FreeSync until it's added to mainline.

                Loving Mesa 17.2/Linux 4.12 rc performance so far. Quake II (Yamagi q2 client) looks and performs much better with the open-source drivers, which I was not expecting. Not to mention all the games that perform better shown by Michael's benchmarks. Happy camper here overall.

                  RadeonSI is part of mesa. the problem is in Linux kernel, you can just run DAL/DC enabled version and get HDMI audio.

                    Could SteamOS have done this ? There is no mandate for them to ship to upstream kernel. They could patch upstream with DAL/DC themselves.
