Unrelated, but I have libappindicator-gtk3 installed and $XDG_CURRENT_DESKTOP is Unity, why do I still get that warning?

@jeremiah-miller Are you using bluetooth audio device?

[jm355]

No, I have bluetooth disabled

[E-D-W-I-N]

@jeremiah-miller Please check this issue - #1811

I believe right now icon is not supported by wireplubmer module. Icon support is already merged into the master branch, but you have to wait for the next version to get it (or you can use Waybar-git package from AUR if you're on Arch).

Try this config and let us know if it works for you:

"wireplumber": {
        "format": "{volume}%",
        "format-muted": "",
},

[jm355]

hmm, that didn't work either. Let me try waybar-git

[jm355]

waybar-git didn't fix it, it still crashed with the wireplumber config you sent

[jm355]

I see a coredump in journalctl -b for waybar, would sending that be helpful?

[0x0aa]

It should work now (worked for me, too)

[jm355]

Huh, it does work now but it seems so weird that that's what would fix it. I already had wireplumber installed, so it shouldn't have been missing any dependencies

Did some investigation after encountering the same issue.
Seems like the wireplumber module has a problem which causes waybar to crash when using multiple monitors.
Using the default config and just adding the wireplumber module (e.g. replacing pulseaudio) or even some customized config - everything works fine with wireplumber and only one monitor active. But enabling a second monitor crashes waybar with

E 23:23:02.657186 GLib (null):(null):(null): g_log_set_writer_func() called multiple times

Can be easily reproduced by enabling/disabling another monitor while watching

waybar -l trace

[laontme]

Same issue. So I just disabled Wireplumber module for second monitor and it's works

[klDen]

I can confirm I have the same issue as @Aimmig using multi-monitor setup
