Start at the > output terminals and go back through the bSourceID's. I really start to like USB. That's how the Creative box should look internal. Host -> [IT1] -> [FU2] -> [OT3] -> Speaker Line-in -> [IT4] -> [FU5] -> [OT6] -> Host That's _very_ minimal. It looks like there is no way to Route Line-In back to Speaker. Just digitally and sampled.. bad. Don't buy that box. The only thing nice is, that it's really 24-bit.
