Any way to Stream Youtube Sound off of Nexus 7 to Yamaha Amp over Airplay? I have the following 3 devices:


a Nexus 7
an iPhone 4s
a Yamaha RX-473, which supports airplay


All are hooked up over my wifi. I've setup Airplay with the amp and the iPhone, allowing me to watch videos on my iPhone and hear the sound out of the Yamaha amplifier, but I'd love to use the Nexus 7's larger screen to watch youtube videos. 

Is there any way to wirelessly stream youtube audio from my Nexus 7 to my Yamaha receiver, in the same way that I can using my iPhone? 

I purchased the AirSync application, but it appears as though that only works for music and video I have on my Nexus 7, not streamed youtube apps, so its not exactly what I'm looking for.
You could try and exploit your receiver's support for the DLNA / UPnP protocols, by installing a DLNA / UPnP control point app, such as BubbleUPnP.
