Audio over DP-MST is currently not supported by the i915 driver, but there are patches (developed since ~2014): https://lists.freedesktop.org/archives/intel-gfx/2016-November/111353.html -- Sebastian

I have tried out the patch including possible fixes for the monitor disconnect issues mentioned in the freedesktop bug, but it does not fix the problem of the disappearing external monitor. Well, that means no audio-out for now, unfortunately. I will have to live without that.
