Bug description:
  [Impact]
  After we plugging a hdmi/dp monitor with audio capability, we could
  select hdmi audio as output device in the g-c-c, but after we do
  that, the profile combo list will show up in the g-c-c and this combo
  list is empty, it should be stereo-hdmi by default according to 18.04

  [Fix]
  Backport a fix from g-c-c upstream, after applying this patch, the
  combo list update signals will be recevied after the pa finishes the
  changing active profile.

  [Test Case]
  Plug the hdmi/dp monitor with audio capability, then choose hdmi audio
  as active output device from g-c-c, we will find the profile combo list
  has hdmi-steoreo as the default profile. This is same as 18.04.

  [Regression Risk]
  It is possible to make the output and input device can't work after
  applying this patch, that is because the active profile is not set as
  our expected. But this possibility is very low, I tested this patch on
  2 lenovo and 2 dell laptops, there is no regression.
