can't get it to work with audioinjector HAT card raspberry pi

[djloot]

I got it working with CAVA but like your version much better. The card uses ALSA and works very well, allows me to mix different inputs. For CAVA, the configuration was: source = hw:audioinjectorpi,0

CAVA doesn't use FIFO. I'm trying to get levels on line-in. Any pointers? I did what you recommended but keep on getting "no audio sources defined"

I'd probably try to use pulse audio first since that is going to be more stable. If you want to try alsa then use the safe_fifo program that is bundled in the project. I decided not to go the route CAVA did for alsa since I thought for the typical user it requires too much setup.

It also would not be that complicated to add a new audio source here that copies what cava does exactly https://github.com/dpayne/cli-visualizer#alsa-setup.
