George, Again, from someone more knowledgeable. "It looks like it may be ALSA based too, which is interesting. Yup, no /dev/dsp in it. Interesting. GPIO is used for PTT." You mileage may vary. Would be nice to figure out what it is.

No docs found except the source contains a line something like it being able to work the DMK Engineering PiTA board. Can't find any docs on that either. But if it can manipulate the Pi GPIO pins instead of using the CM108/119 pins it would be great...
