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 ... /Benny ------------------------------------------------------- This SF.net email is sponsored by: The Definitive IT and Networking Event.
