scope driver is also missing 88.2KHz sample rate selection
i conducted an experiment: set scope to slave and input 88,2 or even 192K through optical, set sync source to s/mux
everything works, i can hear the sound through scope's digital output and see although display is wrong (showing 48 or 96K).
at 88.2 everything's correct via s/mux - i get two channels through s/mux source module, but when I switch to 192, i get 4 channels because s/mux module doesn't understand quadruple rate.
so my suggestions would be:
1. add 88,2KHz sample rate to driver's selection, because the card can handle (generate) it itself - now it's only 44, 48 and 96 - why omit 88?;
2. make the driver and input s/mux modules aware of 176 and 192 sample rates when in slave mode. quadruple rate would give 2 channels via one optical s/mux channel. having 176 and 192 [slave] options would enable digital signal input and output to/from software programs without need of resampling, provided one has an external clock.
if analog i/o doesn't work at high rates, it's no problem, because 'onboard' converters ain't that great anyway and scope's strength is in routing. some scope cards don't have analog at all by the way
176 and 192K inclusion would make scope cards up to date and hand in hand with the best!
