There is another device for IEC958 as well, and there is also a bunch of mixer controls relating to "four channel mode" and "mic as rear" etc. It's *very* confusing. The card is 5.1 and has 3 analogue output jacks, and a pair of optical ports around the back. ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
