Hi,
i am trying to run m8c on patchbox. What i try is to add a USB soundcard (in this case a teensy 4.1 with the m8c firmware) so that the audio from this soundcard gets outputted on my main soundcard (also USB).
On the m8c documentation this is done like this:
aplay output:
pi@raspberrypi:~ $ aplay -l

Start JACK server and route audio
jackd -d alsa -d hw:M8 -r44100 -p512 &

create a virtual port:
alsa_out -j m8out -d hw:3 -r 44100 &

After the virtual port has been created, we need to connect it to the M8 USB Audio capture device.
jack_connect system:capture_1 m8out:playback_1
jack_connect system:capture_2 m8out:playback_2

On a clean raspian this works, but how can i recreate this on patchbox?
