In Pulseaudio, each output device has a corresponding input device. These are actually useful, e.g. when listening to a received signal on the headphones (perhaps from the websdr or some SDR software), it makes sense to attach the HS modem to "Monitor of Headphones" to have it decode it. Pulseaudio also supports virtual sinks that can be fed from SDR software, and letting the HS modem listen on "Monitor of virtual sink" will enable decoding.
