Seems like a user application problem to me.  The cs46xx driver just 
support a limited set of period-size configurations, that's a limitation 
in the HW. Then it's up to the application to handle it (I guess)
I've managed to make AC3 and DTS through SPDIF work witth OGLE and Xine, 
I dont see any reason why it would'nt work with any other application, 
at least you should get further than: "S/P-DIF: Period size not 
available: Invalid argument" then when you've managed to open the device 
and write data to it maybe there will apear other unknown problems ...
