What's your use-case exactly?

I can indeed reproduce the issue you mention with the vimeo player but not with pages using the native controls, like http://www.w3.org/2010/05/video/mediaevents.html

With the page above you indeed should see the initial volume as 1.0 but once playback starts, pulsesink notifies our player of the restored stream volume value and the DOM property is update accordingly, the volume slider is not stuck at 1.0 then.
