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"
  }

what do you name the cava module to get it to show up at all? I name it cava and it still shows up as unknown. And yes, I have built the package with Dcava=enabled.

Hi @raffaem.

1. make sure you're using correct "method": "pipewire",
2. try to run cava as an application and sure it works correct. Please see an example
3. Try to increase "input_delay": 2, to for example 4,6,8 seconds and wait this delay before start playing. It might possible waybar starts much earlier before pipewire server is ready. (On author's second machine this parameter is set to 4 seconds)

THis is my newconfig, same result:

  "cava": {
        "cava_config": "/home/raffaele/.config/cava/config",
        "format-icons" : ["▁", "▂", "▃", "▄", "▅", "▆", "▇", "█" ],
        "bar_delimiter": 0,
        "method": "pipewire",
        "input_delay": 8
  }

The CLI programcava works, although it's the distribution installed one while I believe waybar is linkedwith the libcava bundled with the sources.

[raffaem]

It might possible waybar starts much earlier before pipewire server is ready

This is irrelevant if I restart the waybar, right?

[LukashonakV]

You should restart waybar once delay is changed

[raffaem]

That's what I'm doing

[LukashonakV]

Should be irrelevant. But in your logs one thing looks strange

If I were you, I'd start to check why dbus throws this

[raffaem]

I think xdg-desktop-portal-hyprland doesn't support org.freedesktop.portal.Settings

I had a few issues with the cava module before, particularly with the install locations, but I'll list the steps and config options that I followed to get a working cava module if it helps.

To install:

1. git clone https://github.com/Alexays/Waybar
2. cd Waybar
3. meson build && meson configure build -Dprefix="/usr"
4. sudo meson install -C build

My cava config options:

"cava": {
    "framerate": 120,
    "autosens": 1,
    "bars": 12,
    "method": "pipewire",
    "source": "auto",
    "bar_delimiter": 0,
    "input_delay": 2,
    "sleep_timer": 2,
    "hide_on_silence": true,
    "format-icons" : ["▁", "▂", "▃", "▄", "▅", "▆", "▇", "█" ]
},

[raffaem]

Still nothing.

We don't know what's failing because there are no logs related to cava.

[Myned]

I had this problem initially due to it not being clear enough that format-icons is a required attribute. Though if ;; is still showing for you despite bar_delimiter defined as ASCII null, that points to the settings not taking effect in the first place.

I was able to get your last snippet, barring the cava_config file, to work on my system (Hyprland following NixOS unstable) with the result:

For reference, this is what it should look like with only format-icons defined:

Should be irrelevant. But in your logs one thing looks strange [2024-01-04 08:48:10.905] [info] Unable to receive desktop appearance: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Settings” on object at path /org/freedesktop/portal/desktop If I were you, I'd start to check why dbus throws this

In regards to this warning, it is indeed due to the Hyprland portal not offering that dbus path. I don't have this warning on my system as I add xdg-desktop-portal-gtk as an extra portal, which does provide it. I noticed no effect either way while testing with it disabled.

[LukashonakV]

Actually cava upstream has brought new changes related to the pipewire. I have to take some pause to merge them to the cava library and include it into the waybar

[LukashonakV]

Hi there. Finally I have merged all cava upstream incoming PR into cava library.
@raffaem can you please check this #2925
It might help you. There were some improvements relates to the Pipe wire and Jack audio input interfaces
