I'm pretty sure that all of the controls and indicators go through the 
bus to the host, including the power light.

The CHI bus was pretty neat at the time - in theory you could string up to 
four devices along it, and have mostly-independant codecs handling their 
own sound streams.  I don't think that Sun ever added support for more 
than one, though - the LX had an onboard codec and could use the 
speakerbox one if it was plugged in, but didn't use both simultaneously.

There's enough documentation on the bus to use it if you really want to, 
given a sync parallel bus to interface with - it'd likely be a first-class 
pain, though.
