Question by : How do I make an Outdoor Home Theater work using an HDMI laptop, HDMI projetor, and a car stereo?
Specifically – the Laptop + Car Stereo so that my audio syncs with the video.
Is there a way to route the the audio through my car’s stereo without disturbing the HDMI feed between my laptop and projector?

I would actually doubt that your laptop is sending a digital audio signal over the HDMI cable regardless.. so you have nothing to worry about. It’s more than likely just a digital video port. (HDMI is very laptop friendly as it’s so much smaller a connection than is DVI.. but the video output is identical.)

So… connect the sound output from your laptop to your car as you were planning on. As long as the projector isn’t projecting too far away from the car, and people aren’t sitting too far away from that.. the sound should be synced up just fine.
