This is a magisk module that will modified system audio properties to bring pure audio performance and also restore capatibility from accessing to DIRECT flags or other audio flags on Xiaomi Redmi Note 4x (Snapdragon) in some audio player apps with Hi-Res compatibility on mido (WCD9335).

This package only have aim to restore internal DAC capatibility as bare minimum files without any harsh modification, no other else and not have any means to insult anyone that work with Mido since this is only for my personal use. (Anyone can use it, but DWYOR).

How to control Audio High Perfomance Mode:

• Install M.A.O App
• Go to kernel audio features menu
• Enable features that exist on your kernel.
• Done

Additional library :

• /vendor/etc/audio_effects.xml
• /vendor/etc/audio_policy_configuration.xml
• /vendor/etc/audio_platform_info.xml
• /vendor/etc/audio_output_policy.conf
• /vendor/etc/audio_policy.conf
• /vendor/etc/mixer_paths_mtp.xml
• /vendor/etc/sound_trigger_mixer_paths.xml

Compatibitily ROM of this patch (this for already tested):

• XenonHD Experimental Build
• Syberia OS Official Build
• Pixel Experience CAF Official Build (should work for AOSP build too)
• LineageOS 16 Un/Official Build
• Almost all Pie based ROMs will work

NOTE:

• JamesDSP & Dirac audio effects was removed from audio config temporary (I'm not used that effects anymore)
• Audio High Quality Mode set disable by default. User should enable it by itself when want to use it, to avoid some performance degredation that happen on high gaming or high perfomance usage.
• Some features for audio high quality mode is not exist in all kernel, so not all features will same exist in every ROM.
• This module won't compatible with any soundmod during i use pure audio effects from mido.
