Now audio enable/disable depends on an atomic commit, it doesn't make sence. For wayland, there will trigering an atomic commit, so it works well. But for Xorg using modesetting, there won't. In this case, unplug the HDMI/DP and the audio jack event is not triggered, resulting in still having a HDMI/DP audio output choice.
