it's a digital audio interface, for some info, see here:

   http://www.epanorama.net/documents/audio/spdif.html

in the indy there is a consumer mini-jack connector; you should be able 
to link a dolby surround digital amplifier or a dat or similar digital 
audio device..

see here:

   http://www.futuretech.vuurwerk.nl/i2sec3.html

BTW, on the mainboard, i can see the cs-8411, and there is the 8411.pdf 
inside the audio.zip doc package

apart from the hpc3.ps on:

   ftp://oss.sgi.com/pub/linux/mips/doc/indy/

you should find the isac-s (peb2086) specs here:
http://www.infineon.com/cgi/ecrm.dll/ecrm/scripts/prod_ov.jsp?oid=13633&cat_oid=-9183

but i don't know if it's enough.. i mean, if we should know something 
more on the way the isac-s chip is linked thru the pbus to the hpc3 chip.
