i used SonyMusic _v.9.3.6.A.0.0 _FULL and magisk fix on RESURRECTION REMIX 5.8.3 (android 7.1.2) with magisk v.12 on xperia L
Everything is okay but the radio FM is damaged
Try the next : Install any final mod plus magisk fix (if you use magisk) and in the same case with sound you could restore audio_policy.conf from .bak file in system/etc folder.
i want to use MOD SonyMusic _v.9.3.6.A.0.0 _FULL but not final !!!
Maybe i have defective phone but i have very another result by test. I checked this mod on LOS 7.1.1 Magisk. Without fix i have no sound in phone speaker . And after installation the Magisk fix i have no problem with sound and his regulation
Install this via TWRP
The problem persists
Hello again repey6
i installed again SonyMusic_with_SSE&ViperAudioSE-final on XPERIA L AICP 12.1 01-04-2017
