Normally it has nothing to do with the device files but is a
matter of the mixer setting, at least this is the case with
my SBLive. In alsamixer I have an with the caption "SB Live"

 Card: Sound Blaster Live!
 Chip: SigmaTel STAC9708/11
 Item: SB Live Analog/Digital Output Jack

This has no volume sliders and can only be muted or unmuted.
When unmuted, it just plain works. Audio from any source is
routed to my receiver's digital input. When muted, nothing.
Your's may have a different caption but look for something
titled "Digital Output Jack" or something similar.
