ok, here goes what i did to get sound from all the 4 speakers on my
sblive5.1 ... ( i used 4 speakers ( 2 connected to the front jack, and 2
to the rear jack ))...
 
 
alsamixergui:
 
mute the last culumn: sb-live analog output jack
 
now alsa:rear and alsa:front should work.
how to test it?
 
alsaplayer:
        get a wav file,
        and use:
                "alsaplayer -d rear myfile.wav"
 
xmms:
        get xmms-alsa plugin,
        and in the xmms plugins configuration select alsa,
        device-settings/user-defined:rear (or front)
 
        and try some mp3's
 
if you don't hear anything, then try to find in alsamixergui the culumn
that regulates the volume for the rear ones ( i think it's somewhere
around surround digital ( the best is to maximize all the culumns :-)
 
 
now to test all 4 speakers
 
get a movie file with ac3 sound
 
xine:
        in the config window select alsa audio,
        and select the 4speaker mode or how is it called checkbox
        -
        now play the file
 
mplayer:
        mplayer myfile.avi -ao alsa9:surround40 -channels 4
 
if you need more help, reply
 
bye,
