I have two applications (gnuradio and fldigi), and wish to connect the output of one to the input of the other. The source application is using the ALSA emulation layer, while the sink application has native PulseAudio support. I've accomplished this by loading a null sink module, and connecting the first application's output to the null sink, and the second application's input to the null sink's monitor, using pavucontrol. However, when I restart the programs, the connections revert back to their defaults, and I have to run pavucontrol and remake the changes, which is inconvenient. Is there some mechanism that can remember the connections of these applications between restarts, or some way I can influence an ALSA application which opens the ALSA "pulse" device to connect to a PulseAudio sink other than the default sink?
