This is what I found too. There must be another process that adjusts the alsa config after Pd has already launched. I also wonder if adding the command
alsactl store
would store the settings so next boot it would just work. I’ll have to give it a try tomorrow. fwiw here is the patch I was using to test the audio input. It is a vocoder adapted from the Organelle patch.
