giuliomoro Hi @giuliomoro, Thanks for your response!
At the moment I am just trying to test whether the capelet is working, i.e., whether I can play audio through it.
For testing, I have tried running Example project in both the Extras > audio-capelet and Capelets > audio-expander. Both projects produced sound briefly (one day last week) but are no longer producing sound, despite nothing (that I am aware of) changing.
We are following (as far as I can tell) the setup instructions (see attached for a picture of the jumper wire installation), and the Molex output connectors are connected to a headphone amplifier which delivers audio to headphones.
In the IDE, I have set the Audio Capelet to be "Active" and channels 0-7 as both Inputs and Outputs.
I also tried setting the expander channels when building the project from the terminal (./build_project.sh test_capelet -c "--audio-expander-inputs 0,1,2,3,4,5,6,7 --audio-expander-outputs 0,1,2,3,4,5,6,7") but this did not work.
Any ideas as to what might be the problem / next troubleshooting steps?
Thanks again for your input here.
