Bug description:
[Impact]
On the machine with the legacy HDA audio driver, suppose the current output
device is Speaker, users plug a HDMI monitor and select the HDMI audio as the
current output device in the g-c-c, after that the output volume can't be
adjusted through the volume-slider in the g-c-c. The UI of the volume-slider
could be changed, but the output volume doesn't change.
[Fix]
Backport 1 upstream commit 0f18a662be6ee0d225249d1ad003dfef69294449. The root
cause of this issue is the stream is not got when changing the output-device,
the patch adds the getting stream in the update_sink callback, this could fix
this bug.
[Test]
run the patches g-c-c, plug a hdmi monitor, select the HDMI audio from g-c-c,
then change the output volume via volume-slider, play music, the sound could be
changed with the adjustment with the volume-slider.
[Where problems will occur]
This patch brings the change to the output and input volume adjustment in the
cc-sound-panel, this could make the output/input volume changing not work
anymore, for example, the internal speaker or internal mic work well, after
plugging a headset, the output device changes to headphone, the intput device
changes to Mic, then the volume adjustment doesn't work on headphone and Mic
anymore. But this possibility is very low since I tested the patch on different
Lenovo and Dell machines, no regression found so far.
