The signatures for the chips are hard coded into the respective usb channel drivers. It would take someone with knowledge of the internals of the chips to add support for additional fobs, since there is some reading and writing of specific memory locations within the usb fobs controllers to modify the behavior of the audio device.

To use the on-board audio, you could look at chan_alsaradio.c.

Correct me if I'm wrong, Isn't the question about using the AC97 on board sound device in asterisk?
For COS and PTT, yes the LPT port can be used.

Again, forgive me. New to this...

I have ordered a couple of CM-108 USB FOBs for the AllStar Project. I am curious... with the ability to do some script editing to use a PC's LPT Printer Port as a "GPIO" for COR, PTT, etc., could the Integrated Sound Card on the Mobo (which is mostly AC97 Chips) be used for Audio In and Out of the Computer? Running DIAL.

Thanks
