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.
