A buddy of mine purchased one of the Chromecast dongles and we put it on my Onkyo receiver (front HDMI port), which was hooked up to my projector (rear HDMI port). That way the sound went through just the receiver and the video went from the receiver to the projector. Worked great once he got it set up with his laptop, which was interfacing with my home wifi. I moslty sat and watched him fidget with it setting it up while I worked to get the receiver to switch over to the front HDMI port. Wasn't as simple as it should have been, but we did get it working.
