- Add this in device.mk: $(call inherit-product, vendor/ViPER4AndroidFXRepackaged/config.mk)
Add this in your dt at configs/audio/audio_effects.xml:
<library name="v4a_fx" path="libv4a_fx.so"/>
<effect name="v4a_standard_fx" library="v4a_fx" uuid="41d3c987-e6cf-11e3-a88a-11aba5d5c51b"/>
Also you need to address some SELinux denials in audioserver.te:
get_prop(audioserver, vendor_audio_prop)
allow audioserver unlabeled:file { read write open getattr };
allow hal_audio_default hal_audio_default:process { execmem };
