Automatically connecting multiple input devices via patchbox-module?

Patchbox OS
1

Hi,
I’ve got a rpi running patchbox that is connected to both a pisound and a usb soundcard. I am running a pd patch that successfully uses 4 inputs and 2 outputs. However, I need to connect the usb card each time via patchage or jack-connect. I’ve been trying to modify the puredata patchbox module for my purposes but can’t get the order of things right.

I’ve duplicated all the files in puredata-modules into a new folder in puredata-modules/imported/ and am making changes there. launch.sh now points directly to my pd project, and also tries to connect the soundcard via alsa_in and then jack_connect..

When I boot with this module, the usb device shows up in patchage, but it isn’t connected to puredata. Here’s my launch.sh file: Does anyone see any glaring errors or have hints for things to try?
