its not. ALSA doesn't require anything but a fairly small set of function pointers to be initialized so that the "mid-level" code can manage the device. as long as there is some way to move data to and from the audio interface (which seems like a pretty basic assumption), you just have to wrap it up and present it to the mid-level code. --p _______________________________________________________________ Have big pipes?
