Ah. Can't help you there but others here have done that. I have only used paralell port pins for COS and PTT on standard micro PC cards (D945, etc) just starting on the pi trail now.

This is what I am trying to say:
There are several cases when I don't want to use DSP and use COR. (Weather we are using flat or speaker is not relevant)
On the raspberry pi, it is easy to use the wiring pi program and a modification of K0KN's astled script for PTT. However, I have no idea how I would wright a script to tell Allstar that there is a COR detection when the GPIO input on the pi has gone high.
If anybody knows more about it, could they help with a script? The bash command "gpio read <PIN number> " will return a value 1 or 0. How do I pipe this to Allstar COR?

One has nothing to do with the other. Use the CM108/119 FOB for the audio, and COS from the radio to the GPIO COS in.
I wouldn't use speaker audio, BTW.

It seems easy to use GPIO as an output to toggle the Transmitter, but I can't figure out how I would use the GPIO on the pi as an input for COR if I am using speaker audio

even better GPIO on the pi

I think we're on the wrong track with our fixation on cmedia hackable chipsets. It's too hard.
Why can't we use one of the other DSP modules and some serial USB _TX signalling?

Does anyone have a reliable source of modifiable USB audio devices?
It's really really difficult to find hackable ones without buying one here
and there...
