I'm trying to direct the sound from Youtube running in Opera to my sound card's HDMI output (to a TV), but still have all other OS sounds go to my PC's Built-in Audio Analog Stereo playback device.  I'm able to get everything to go to one device or the other, but can't find a way to split the sound like I need. I suppose because Opera/Flash (and probably most everything else I'm using, like Wine games) are just not Phonon aware, so they end up in the Default/Unspecified Category).Is there some way to force a specific application into one of the other audio playback categories (see below)?  Any other non-distro specific Linux solutions? I'm using Kubuntu (14.04), and it appears I have something called Phonon multimedia framework installed here in charge of all this.
