Hmm, not sure I've ever had a computer with 5 audio plugs. Actually, I'm trying to sort through the various audio connectivity standards to find which works best for me. Because I don't need a large screen, and because the screen is the usual bottleneck for desktops/laptops, I use a small but powerful laptop as my main computer (Lenovo Helix for the curious.) Unfortunately, since this is a laptop, audio connectivity is pretty limited, and I'm in the market for a quality USB audio device that'd allow at least 5.1 connectivity.

If you have any headphone/USB interface buyer's advice to offer than I'd be interested. At the moment I'm lacking enough connectors for a 5.1 interface with this setup and certainly lack same for headphones. :)
