I switched to CM11, and DSP Manager turned out to be my savior. Music feels full and immersive, and I can actually hear the low end.
But I really like every single other aspect of Sense Lollipop, especially the camera's low light performance.
Does anyone know of a way to put DSP manager on a Sense Lollipop ROM? I tried putting the apk in a folder in system/app and swapping the audiofx folders, but no dice.
I would greatly appreciate help, and wouldn't mind taking the time to create a flashable zip for others to use.
