I am trying to get an AudioInjector stereo soundcard to work with SamplerBox on my Pi3, to no avail. I have edited config.txt to load correct device tree, and changed Audio Device # in samplerbox config.ini, but can't seem to get it to work. It is working in Raspian, but not with the bootable SamplerBox card. Wondering maybe if it has something to do with DPIO pins #'s. Any suggestions?
Well I did get it to work, using the basic image (samplerbox_20170710), changing settings at the top of samplerbox.py, removing any possible DPIO conflicts. (I just noticed this is how it is set in the Joseph Ernest github file, but they are set to True in the image download.)
USE_SERIALPORT_MIDI = False
USE_I2C_7SEGMENTDISPLAY = False
USE_BUTTONS = False
I also did some tweaking in the alsamixer, turning on hifi output. Working great now, excited to load up more sample-sets!
