And the IC uses I2S, another standard bus that could be good to use. Overall, what I'm most impressed by is their timeline--completed the device plus linux drivers in about 1 year. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
