The center channel on the SB Live is the one that doubles as the S/PDIF 
output. I think it is producing the digital signal; if I plug it into an 
analog connection on my receiver, I get that buzzing sound as well. Try 
toggling the digital option in alsamixer. (The last one there. It looks 
like a slider but isn't. Mute it.)

How did you get analog surround to work? I've got digital output working 
and the front analog, with no arguments to aplay. I'm trying to get 
surround working, like this:

     $ aplay -D cards.pcm.surround51 2.wav
     Playing WAVE '2.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
     aplay: set_params:764: Channels count non available

Other options (cards.pcm.iec958) give the same thing, even though it 
produces digital output fine without me specifying anything.

It's a bit silly to play a mono file in surround sound, but it should 
work, right? If not, I suppose I can try with the DVD software, which is 
the point of this in the end.
