Hi!
The noise you’re describing is unfamiliar to me, but I’ll ask my colleagues if your description of it reminds them of anything they’ve come across.
Meanwhile, to get straight-forward passthrough, use the config file ~/config_files/config_empty.json on your elk pi - it contains a single pass-through plugin.
mind@elk-pi:~/config_files$ sushi -r --multicore-processing=2 -c ./config_empty.json
Did the trick for me - I hear clean pass-through.
Things you can check, if that doesn’t work:
- Try a line-level sound source - just your phone playing music for example
- Connect directly using your Y cable to the elk-pi
- Double check the version of your image - is it the latest 0.9.0 release, for the Pi4?
Regarding the terminal error you’re getting, it may be that you have versions of the elk-examples, and the image, mixed up - I don’t get it locally on my board with the multi fx example, with the code freshly pulled from the repo on the latest image.
Best,
Ilias of Elk
