First and foremost, I'd recommend that anyone who uses magisk installs this module
1. Freeze any other audioFX, musixFX, dolby service etc using titanium backup
2. Rename /system/ect/audio_policy.conf to audio_policy.conf.bak
3. Install Selinux permissive script thru magisk
4. Install busybox thru magisk or play store
5. Install v4a thru magisk repo or here. (IF not installed thru magisk, you must install it as a system app. Do this by moving it to /system/app and setting permissions to rw-r--r--)
6. Reboot
Profit
