When listening to a song on my home cinema system (by bluetooth) and switching from low to extreme audio quality, i hear no difference at all. I teid the empty cache, clean reinstall, changing the quality then starting the song again... no matter the quality stays the same. I have Premium family plan. Is there something I'm doing wrong?? I have FLAC songs that I converted to mp3 (128 and 320) and hearing the difference.. but nor on Spotify. Any Spotify employee here to help? Thank you for your help.
