      Are the issues with audio over hdmi/dp actually gone with 4.16/4.17? I use a 4.1.5 kernel with the boot option to make use of amdgpu.dc, but still no audio...

        Not sure if it was backported to .15, but 16+ are good AFAICT:

        EDID channel count patch

                Does anyone know if 4.17 has stabilized GPU functionality on the Raven Ridge GPUs?

                  It got fixed for me with the previous fix commit for 4.17.

                    The audio channel count bug got fixed a while ago, the fix is in 4.17 and should be backported https://bugzilla.kernel.org/show_bug.cgi?id=196637
                    and https://bugs.freedesktop.org/show_bug.cgi?id=101900 this enables HBR audio like DTS HT master and so forth.

                    But the bandwidth bug present since the early days is still there and not fixed yet. https://bugzilla.kernel.org/show_bug.cgi?id=86351
                    problem, from what i heard & understand: the amd guys aren't audio experts, so this isn't a priority.

                    So the audio 'flickers' depending on the load of the machine.

                    Any help is welcome.
