I can't get the native Audio Effects to work properly in my Moto G. The EQ presets don't do anything and neither do the ambient, surround and reverb. Third party apps are no better. Every EQ I have tried either has no effect or, when you boost one channel, everything else drops out instead of the boosted channel getting louder. I have tried different players and different combinations of effects processors. I have uninstalled everything except the EQ I am using but still no improvement. Any suggestions?
