I've tried to remove YouTube player from sounds menu in Ubuntu 13.10 but it doesn't worked.
I've done all these things from this webupd8 site.
I've already added to blacklisted player but it still shows in sound menu
gsettings get com.canonical.indicator.sound interested-media-players:['YouTubeyoutubecom.desktop', 'rhythmbox.desktop']
Also I have been tried dconf tools but it still results the same.
dconf settings here:
youTubeyoutbecom.desktop
from dconf settings?
