Hi, I got the gmfsk program outputing digital data through the headphone jack like I want, but no sound inputs work, either mic or line in. Mixers show input on 100% and not muted.
The solution for getting sound out of the Gmfsk program was taking its /dev/audio out of "stereo mode." I would like to run the Linux Baudline spectrum analyzer program to check the inputs, but it sounds like compiling it could be a mess. Rob
