Hi. I made my mods based on port of Dolby Atmos from HERE. Need custom recovery adapted for 8.0(oreo)(recommend TWRP 3.2.0-0+)
Dolby Atmos Oreo mods
Mods work with magisk and also with supersu. Combination with Viper FX 126.96.36.199 give you simply wonderfull sound. All build simply different . Need select for self more compatable. Maybe temporary bootloops after reboot from recovery , dont worry try reboot else one(only one). Sometimes on roms with magisk root is lost. Do reboot. Mods which with Viper's prepared can install via TWRP and then can install ViperFX 188.8.131.52 as ordinary application. So in magisk roms you can delete Dolby via magisk manager and Viper FX from rom settings .
Who want to get mod with SonyMusic&ViperFX&DolbyAtmos can add to DolbyAtmos&ViperFX simply Sony Music application from here .
Install mod via TWRP. If you select mod with Viper need after start system start at first Viper then player and then Dolby. Now you can do settings of sound. Will may be bootloop. Try else one after hard reset. Notice. You can have issues with Viper's work. In this case you have a solution by@docnok63(click link) . More info in main thread.
For using magisk root roms:
Mods with Sony Music Player that you want to restore system completely please use backup from recovery or flash your rom without wipes.
For mods without Sony Player you can at first delete Dolby module in magisk and then use Viper's uninistaller that delete Viper and restore system files.
For using supersu preferable use backup from recovery or flash your rom without wipes.
