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.
