CM11/Aosp sound distortion fix
This is my first contribution to XDA, if it helped you please click the thanks button.
I've seen many people who go back to Sense or GPE Roms cuz of the sound distortion we experience with our m7 & m8 models.
I mean come on, we audio freaks buy this phone for its amazing sound quality & screen quality.
Anyway, I've attached some screenshots to this thread with my settings to Viper4Android (V4A).
Note: this will work on S-on & S-off devices & all Roms without boomsound/Harman kardon.
It's just a application so don't worry hehe.
Download viper4android apk & install it.
Choose the highest quality sound & reboot.
After you rebooted your device just copy my settings.
Tick the 3 dots on your upper right corner & go to UI settings and choose expert.
