Hopefully your `aplay -l` should now contain a loopback interface.

To keep it form beeing loaded as the first soundcard add the line `options snd-aloop index=1` to "/etc/modprobe.d/alsa-base.conf", this will load it at '1'.

Playing the audio through your Loopback interface makes it possible for cava to to capture it, but there will be no sound in your speakers. In order to play audio on the loopback interface and your actual interface you must make use of the ALSA multi channel.

Look at the included example file `example_files/etc/asound.conf` on how to use the multi channel.

The PulseAudio method however works perfectly on my PI.
