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.

      AudioStreaming Interface Descriptor:
        bLength                11
        bDescriptorType        36
        bDescriptorSubtype      2 (FORMAT_TYPE)
        bFormatType             1 (FORMAT_TYPE_I)
        bNrChannels             4
        bSubframeSize           3
        bBitResolution         24
                               ^^
