A lot of devices implement extra channels with TDM rather than with extra wires - you get all the left channels and all the right channels grouped together (like with DSP/PCM modes except the channels are ordered differently). I'm never sure that's actually useful, though, since it's not something that just works with most hosts that don't understand it in hardware and most of those can do DSP/PCM anyway.
