I just plug my HDMI cable by hand directly to my PC when I am watching something 3D. My PC has optical digital going to my receiver, so then I get 5.1. For 2D movies, I plug the HDMI back into my receiver's output, where I have my PS3 hooked up with HDMI so I get the 7.1. If you have only one Blu-Ray source, say a PS3, you would have to be telling the player to output audio either through the optical digital or the HDMI from time to time, because it won't output surround formats through both at once, but once you learn the menu settings that wouldn't be too hard. I don't recommend trying to get some HDMI switch or splitter, it isn't that hard to physically move the HDMI plug.
