No equalizer responding except for PowerAMP

I just bought an AT&T Note 5 yesterday. While loving it, I can't get the equalizer to work. I've tried several equalizer apps and the Spotify onboard equalizer but none of them work. The only one that does work is the PowerAMP built-in EQ. But I only use Spotify as my main source of music as all of my playlists and collection are through the app. My downloaded playlists are not recognized by PowerAMP so I can't locate them with the app. Has anyone had anything similar or any info on how to remedy the issue?
