[ Impact ]

Not able to adjust Audio input UI volume if this device doesn't have a
internal mic, the volume bar will be gray.

[ Test Case ]

1. Boot ubuntu without any external headset connected.
2. Launch gnome-control-center and switch to Sound->Input tab.
3. Connect external headset, then you will find the input show up but can not adjust the volume.

[ Regression potential ]

Low, The first part of the patch is a workaround for a bug elsewhere
which is reporting things in the wrong order. The second part is a fix
for a case that wasn't being handled correctly.
