Default [Q] How to install Viper4android on LEWA bases ROMs

Currently I'm on Swift-Li LEWA OS-5 ROM. I tried to install Viper4android, beats audio and DSP manager . They got installed but none of them worked. Can anyone please tell how to make Viper4android work on LEWA OS. Or please suggest any audio enhancement apps which work on LEWA .
Please help devs.
