We have reverted the patch for the time being, since we didn't find a fix in a timely manner.
Created attachment 44989 [details] volume/duration notifications support I reapplied the patch from Bug 30377 also did some minor coding style fixes. It seems that setting the volume on playbin and just after connect to the notify::volume signal was causing problems. Anyway it was not needed as by default it is 1.0 both in playbin and in the MediaPlayer.
