Equalizers on phone wont work!!!

[AC Question]

I Have been using Equalizer+ for a while and a while back the equalizer stopped working. I was told that it might be interference with other apps so I deleted/disabled every music app (Except for default music player) and nothing worked so I referred to: Android 5.0 (Lollipop) music equalizer? and yet I could not find music FX anywhere on my apps. It is beyond me how to get the equalizer to work on any app. It doesnt work on Equlizer+, Bass Booster EQ, Shuttle, Rocket Music Player, or any others for that matter. I have ran out of options and I really want my good sound quality back. My phone is an LG Leon if that helps and is running Android Lollipop 5.1.1 PLEASE HELP OMG I am completely out of options!

Welcome to Android Central! Do you remember if the equalizers stopped working after a particular system update? It's possible that 5.1.1 makes them ineffective, while they still worked fine on 5.0.2 or under.
