This is what Proc/asound/usb/usb mixer says:

Should there be a pcm slider for capure?(not clock capture)
I can't be sure, but it sounds like voip is "capturing" the sound of the clock.

Just updating this:
Whilst the volume control does nothing on the tray, if an application has a volume control on it, VLC, MPLAYER and others, the volume does work.
And works very well with good resolution!
So mostly solved (unless an app doesn't have a volume control).
