Galaxy S5 :: Music Equalizer Not Working Properly (lowers Song Volume When Raise Band Levers)

When you are playing a song on the factory installed Google Play Music app or any other app with an equalizer or when using a separate equalizer and you increase any of the bands in the equalizer, the overall volume of the song drops.

To easily reproduce the problem, start playing a song on the Google Play Music app, go to settings, select equalizer, select advanced. Set the equalizer bands to flat (in the middle settings for all bands). While a song is playing, raise any equalizer band and the overall volume of the song goes down dramatically, like by half. This is especially noticeable as you increase the 16k slider. This is not how equalizers should work. A working equalizer should amplify the band you increased but leave the volume on all other bands the same and thus not lower the overall volume of the song. This is happening with all equalizer apps I've installed (besides the stock Music FX and SoundAlive equalizers) and I've seen the exact thing happen with three other equalizer apps on this phone, so it seems like a specific Samsung Galaxy S5 problem.
