This is my first post so please bear with me as I'm prone to asking dopey questions. My hope is to somehow use an interface like the Tascam US-366 or the Steinberg UR28M and connect it to the optical input on a home theatre so that I can record/playback in 5.1. I use Cubase with a MOTU interface downstairs in my playroom but I'm planning on a good laptop that I can work on in the living room. I am married (therefore whipped) and he is not going to tolerate another 5 monitors in the living room. I just want a more low-key set up to mix but I have a feeling it's not as simple as connecting optical out of an interface into the optical in of the surround sound receiver. Any info or advice is greatly appreciated. Thanks.
