Viper4Android not woking

hello guys
im using a xperia z5 e6653 on MM 6.0.1 32.2.A.0.253 with open BL, stock firmware and kernel
i am trying to install viper audio mod without success. after flashing the last zip and installing the driver (busybox installed, of course) the driver status tells, that the driver is installed, working, using neon BUT the proccessing is disabled. none of the sound modifications are working.
can anyone tell me why?
thanks
