Pulseaudio slider doesn't show up

[trya2l]

Hi,

I'd like to try the pulseaudio-slider module, but it doesn't show up. The pulseaudio module works well however.

I'm on nixos and here is my config. I'm a bit confused because I never saw someone having an issue with it.
(On debian, I've never succeeded in using it either)

Have you ever started waybar from terminal and/or looked at log output? With your config, I'm getting this: [2024-07-01 18:25:52.076] [warning] module pulseaudio-slider: Unknown module: pulseaudio-slider There is actually a bug in the manpage example.

           "modules-right": [
               "pulseaudio-slider",
           ],

is wrong, it needs to be

           "modules-right": [
               "pulseaudio/slider",
           ],

[trya2l]

That's it, thanks! How did you know about that ? Is there an issue about it ?

[RobertMueller2]

Well, not really. "pulseaudo-slider" just struck me as odd, because it's not the usual notation for categories and modules. So I tried your config, saw the error message about it being an unknown module. Then I tried the way I would expect it to be named, and that was it. ;)

We corrected the manpage now with PR #3399.

It is also correct in the wiki: https://github.com/Alexays/Waybar/wiki/Module:-PulseAudio-Slider , but to be honest, I haven't looked there earlier, either.
