Even though I'm enabling equalizer (through Gramophone app from f-droid), it feels like the equalizer doesn't get applied to anything: browser (Vanadium), youtube (NewPipe) or even the very same audio player (Gramophone) when the tablet is connected to a dock.
Dock's Audio Quality out-of-the-box is miserable: even when someone's talking, all you can hear is bass and I just want to remove this hideous bass.
