the breakout cable can receive proprietary Alesis ADAT TC
information. its a totally different signal and has nothing to do with
sample sync. i can't repeat this too often.

right. you can choose word clock, but if there's no word clock source,
it will default back to the internal word clock source (the h/w does
this, not the driver).

thats correct. there is no 96kHz rate for ADAT. there is no way for
card1 to know that card0 is operating at "double speed mode". this has
always been a hack on all ADAT equipment: you have to explicitly tell
(by pressing a button or running some s/w) each end of the connection
that you're running in double speed, since at the low level, things
have stayed exactly the same: the bits still move at 48kHz. they just
send 1 "channel"'s worth over 2 channels.
I can then not bring the cards back to 48000 or 44100 unless I

it is supposed to stop you from doing this if the card is in use,
because it changes the channel counts and thus many other things.
what were you using to try to change the rates?
