While adding effectiveVolume, I did small changes to effectiveMuted. The effectiveMuted routine now checks for m_mediaController which was not the case before. This slightly change the behaviour in updatePlayState(). In case of m_mediaController , HTMLMediaElement::updateVolume() was setting the player muted state without considering its muted() state (but only m_mediaController and page states). I believe both changes are correct.
