I have analog 5.1 speakers on my PC which I have owned for several years. When I bought the speakers, I remember seeing 7.1 setups for sale too. Now I can't seem to find 7.1 computer speakers on sale anywhere. Looking through my DVD collection, I can't find any movie that claims to have 7.1 audio (most have 5.1 audio). Has the 7.1 standard been abandoned? If I want to upgrade my computer speakers, what is the state-of-the-art format that I should look for? I want to use these for PC games, movies, and game consoles.
