[arm-allstar] C-MEDIA HS-100B

[Skyler F]

I have noticed the surprisingly the hamvoip image has support for the
C-Media HS-100B! I plugged in a soundcard with this chip, and I got audio
out of it and asterisk recognized the chip.

Does anybody know if this chip has any PTT GPIO lines supported? With my
meter, I could not get a voltage reading on pin #13 while PTT was active. I
also looked at the image of the chip and see no GPIO

If there is no GPIO on this chip, is there any reason hamvoip supports it?
