Does the sound card show up properly as a recording device with pulseaudio? If not, then minimodem isn't going to see the card or any sound coming from it. Also note that on some pi 2 models that only have one 3.5mm jack, that jack is going to be A/V output only, with no input capabilities. AFAIK, the only way to get audio into these is to use a USB audio input, which I'm sure you can find for cheap on ebay and the like. I have a RPi model 2B+, but since I don't have an input on it, I can't test anything for you (yet).
Hope this helps.
You don't have to use Pulse Audio. You can use ALSA if you use the -Ax tag where x is the card designator in 'aplay-l'.
First of all, minimodem is awesome!
Though, I'm failing to make the Raspberry pi the receiving end. It just doesn't receive any data (I even don't see the on-screen logs). I'm using a Raspberry Pi 2 with a Cirrus Logic Audio Card. Did somebody tried it out?
