The hub works great for the home office, which is 95% of how I use it. But occasionally I connect my laptop to the home theater to play games or watch movies. And in this scenario, if you configure your laptop to send 5.1 audio to your receiver, you only get left and right channels. You get no signal at all for the other four channels. Took me a while to figure out it was the hub that was the issue. Swapping it out for a different hub fixed my problem.
