I'm trying to rip my minidisc collection to FLAC using a Creative Labs Sound Blaster (SB1240). My old (and amazing, by the way) Yamaha MDX-596 - probably 17-18 years old - has an optical output that takes a Toslink cable and it works fine into the optical input of an amp, which means I assume that it's a digital, not an analog, optical signal being output. But plugged into the Sound Blaster, no signal. What am I missing, hivemind? (The Sound Blaster sees the player if I hook it up through the RCA, but I'm assuming the optical signal will give me a better rip).
