2.2.7 flatpak displaying "Sound Off" on the UI but there is sound
Qt-based Multimedia Player

Earlier versions displayed the volume as it actually is. For whatever reason, the newest version of QMMP displays "Sound Off" on the UI instead of the actual reported sound.
It is not actually off, there is sound.
Clicking on it restores the sound volume indicator.
Try to select PulseAudio output plugin (or PipeWire if available).
