I triend to use it again and force it to work using different equalizer and player settings (hi res audio on or off, turn off 100 step volume control) but nothing works. I tried also to use any different eq from play store, and almost none of them is working (wavelet works only when i check "legacy mode").
Also, When I try to turn on visualizer - nothing happens, like this app is not "catching" audio stream (maybe it will help in solving my problem).
Maybe someone knows why is this working like that? I use Xiaomi mi9t pro, MIUI12 EU ROM (not xiaomi.eu, just stock EU rom).
