Adobe does not understand that not everybody wants to hear sound for videos unless the visitor opts for this.

I mute the sound for Adobe Flash Player in the Windows 8 Speakers > Mixers section.

But the next time I visit a site with a Flash video with sound, Adobe enables itself and sets the volume to the speakers volume.

Does anyone know a registry tweak to tell Adobe Flash Player sound to shut the f*** up until I ask it to play?
