Describe the bug

With AudioFX enabled, and different presets selected - there is no audible change to the sound, even with extreme settings.
In contrast - standard Music application for CalyxOS that also uses AudioFX, works with different eq settings as expectted

Expected behavior

With AudioFX on, and treble sliders all down - I will hear audible difference in outputing sound
