how to get alsa to send info out my TOSlink port

[jerry garcia <jazzmans69@cox.net>]

Hi list!

I'm using 2.6.3 kernel, debian sid and a sound blaster audigy card with 
the add on box that uses a cdrom slot and has a fiber optic (TOS-link) 
output.  When I was running a knoppix (sarge/sid) distro with the 2.4 
kernel, I was able to get musical information sent out the tos-link, but 
now that I'm running a pure sid distro,  Alsa doesn't seem to send any 
information out the port.   I know the hardware is fine, because if i 
boot from a knoppix 3.3 cd, the toslink works again.  Sound works using 
the small output from the card itself in the back of the machine, and 
from the headphone output from the breakout box in the front, but not 
the TOS-link.

Any suggestions?  I'm not too proficient with alsa to be honest, and I'd 
bet it's something as simple as a configuration file.

Thanks for any suggestions in advance, if any more information is 
needed, I"d be happy to supply it.
