Maybe this is the problem: sound daemons. You really dont need sound
daemons. But im not sure about the problem, keep searchin.
But they can give you more funcionality (ie JACK daemon for low latency
realtime audio+midi); this is another history.
Have you tried the surround with VideoLan (VLC) and a surround movie or
somethin? (I have the same realtek sound chip, and all channels works!)
Check that channels are not muted...
