The list of audio devices and their names can be obtained using the command: pactl list. This will generate a lot of text and you will probably want to pipe this through less. The interesting modules are those of type “Source #” for input and “Sink #” for playback. The pulseaudio device name is then the weird text string shown under the ...

Loop through our // structure and find the first one that's "uninitialized." Copy the // contents into it and we're done. If we receive more than 16 devices, // they're going to get dropped. You could make this dynamically allocate // space for the device list, but this is a simple example.

I think that modules are responsible for adding devices. E.g. there is one called module-udev-detect, and if I do pacmd list-cards in my system, I see module-udev-detect.discovered = "1" in two out of the three. The third one is a bluetooth device, so I guess that one comes from the bluez5 module.. Looking at the web a bit, you can make pulseaudio ignore …
