Unable to capture audio from applications despite dependencies being fulfilled

[gPhantasm]

The plugin does not show any applications, despite pipewire, wireplumber, pipewire-pulse, pipewire-jack, and pipewire-alsa being installed. Is there something else that I'm missing?

Audio Output Capture is for capturing audio output devices. The source you're looking for is the "Application Audio Capture" source
