The system can't detect its plugging and can't output sound to it anymore. [Fix] This is because we backported a patch from stable updates, and that patch is for v5.2 kernel, if we backported it to 4.4 kernel, we need to do some change, and also we need to backport one more patch from stabe kernel. [Test Case] Connect a monitor to the machine and boot up, after booting up, we could see the hdmi audio is found, and play sound to the hdmi audio, we could hear the sound from monitor. [Regression Risk] It is possible to make the hdmi audio fail to work after applying this patchset, like the hdmi audio can't be detected after plugging a hdmi monitor. But this possibility is very low, we tested the patchset on many dell and lenovo machines, all worked well.
