cava shows ";;"

[raffaem]

I compiled waybar from git using the instructions here.

In my config I have:

  "cava": {
//        "cava_config": "$XDG_CONFIG_HOME/cava/cava.conf",
        "framerate": 30,
        "autosens": 1,
        "sensitivity": 100,
        "bars": 14,
        "lower_cutoff_freq": 50,
        "higher_cutoff_freq": 10000,
        "method": "pipewire",
        "source": "auto",
        "stereo": true,
        "reverse": false,
        "bar_delimiter": 0,
        "monstercat": false,
        "waves": false,
        "noise_reduction": 0.77,
        "input_delay": 2,
        "format-icons" : ["▁", "▂", "▃", "▄", "▅", "▆", "▇", "█" ],
        "actions": {
                   "on-click-right": "mode"
                   }
    }

But the cava module is shown as ";;":

I've also tried build and installed subprojects/cava-0.9.1/. Same results.

Not a duplicate of #2781 as that seems to be cause by waybar compiled without the cava module altogether.

I've also tried the following config:

  "cava": {
        "cava_config": "/home/raffaele/.config/cava/config"
  }
