There is a interesting appearance. First, I plug in the cable, the tab
do not list 'HDMI / DisplayPort' selection. When I execute 'apport-bug
audio', following the steps, I can hear the sound from external HDMI
screen. Then I re-open the Sound setting window, the 'HDMI /
DisplayPort' do list on output tab.
