Question sound effects/equalizer not working

Hey there all I'm running stock android KitKat 4.4.2 rooted with CWM and I have notes recently that the sound equalizer option in the sound configuration menu is disabled even though the MusicFX is enabled in the device, I tried installing Volume+ as a temporary fix and when trying to open it it crashes.
As a reminder when setting the android sound enhancer, it doesn't matters which I choose they both crash.
Any ideas about what causes them to crash and a possible solution will be appreciated and tested
