Comment 21 for bug 883485

Sorry for spamming like this (I am more used to fora, where you can also edit your posts), but it seems using "PlaybackPulseAudioMixer" causes me to control my HDMI output with the media buttons. I have no idea how to get this right. Maybe I should try using #2 as a lead. Although I think I just haven't found the right name to enter in that xml file. Any ideas to what other names I could be using?
