Release/Download: https://github.com/james34602/JamesDSPManager/releases
If you look at the source code from Java part, you will find some are similar with Viper4Android, but this is not true.
Viper4Android only open source it's interface, their core drivers source code have never been released.
For convenient sake, I copy some interface code to accelerate my development.
How to compile the source code?
Use eclipse && Android NDK will do the job.

This guy are cool! They have tested to use JDSP with v4a! https://forum.xda-developers.com/apps/magisk/module-jamesdspmanager-2017-10-15-v1-1-t3689390

I reach my milestone and made 14 Band Equalizer works @ 32, 64, 126, 200, 317, 502, 796, 1260, 2000, 3170, 5020, 7960, 13500 and 15000 Hz
And more nice bass filters

I have done more on optimize the audio engine, it use less and less CPU usage than before.
So far I have update:
Pure stereo widening.
Reduce band number to 12 bands.

great! this is purely cpu based? can it be hardware accelerated for less CPU utilization?
also a flashable zip would be nice

Tunnel player?
james3460297 , looks very promising. would this bypass the tunnel player that most Samsung phones use allowing for audio visualizers to work?

@james3460297 ... any plan to support magisk module for this ... seems promising. thanks for the works :good:

Currently, I don't have plan to do so, because I don't have magisk framework development experience...

I don't have extra time maintain, you could help keeping update if you like to

Before this latest update, I did a lot of test on high efficiency convolution engine, it's CPU consumption are much less than b4

Arm64 support? And do i have to uninstall any sound modifier before install jsdp?

It looks like it works fine on my phone (MT6755, ARM64, Android 7.0) without any additional steps. I just flashed JamesDSPManager-v1.5-HQ-Auto.zip via TWRP recovery. I didn't remove anything or do other things.

James, would it be possible to add a parametric EQ where users can add custom frequencies and Q factor.
There is no parametric EQ on Android that works systemwide, i hope yours will.

Magisk modules

Which magisk modules are out there for the oneplus one?

I remember "mic fix" and "stereo mod".
arise and root
There are a lot out there..!
Actually there are a lot out there but it depends on you what is required to you for example i wanted better music so i installed viper4Android so for your question there are a lot out there but you need to install only what you need. so here goes my favourite list.
CrossBreeder Lite Edition
CrossBreeder is a set of mods that are used to modify system performance as well as conserve battery life. While the original project required proper /system access, it has now been ported to work with Magisk, and it works exceptionally well. You can use it to reduce the lag, increase your entropy levels, get more juice out of your device and speed up your mobile.
Audio Modification Library
There are a number of sound mods available for rooted Android devices, like the aforementioned Viper4Android, AM3D Zirene and Dolby Atmos . Based upon your liking, you may want to one of them. But what if you like different features of different mods, but installing both mods at the same time would result in a system failure for you? Well, Audio Modification Library is a Magisk module that overcomes Magisk’s limitation of installing multiple audio mods, and does not cause any compatibility issues.
Viper4Android or AM3D Zirene
Viper4Android is by far one of the most feature-rich and advanced music mod out there for Android. It lets you alter almost each and every aspect of your device’s audio capabilities, thus giving you full control. It lets you customize the audio performance of your device’s speaker, Bluetooth speaker, headset or even a dock. The app not only increases the volume of the audio on your device but also improves bass & clarity, thanks to the cool ViPER Clarity and XHiFi technology.
Even though the interface is fairly easy to use, one might get confused with so many choices at their disposal. If so, you could opt with the AM3D sound mod by Zirene, which offers a simple and minimalistic interface, allowing easy tweaking around with the audio profiles for your system.
Dolby Atmos
Lenovo had introduced Dolby’s Atmos Sound technology to their devices a couple of years ago, something that was widely appreciated. The Dolby Atmos Magisk mod brigs the Dolby Atmos audio enhancements to any Android smartphone. The mod offers simple yet efficient sound modifications to the overall audio quality of one’s device. This app, which was earlier exclusive to Lenovo’s ROMs, has now been ported to Magisk, so that it can work systemlessly. You can customize the audio quality of music, movies, games, voice, etc. There are a lot of options here and if you are an audiophile, you will definitely appreciate the features on offer.
Android Mic Fix
Many a times, after flashing a new ROM or firmware, you may experience a loss in the mic quality of your device. The reason behind this is that most of times your build.prop file is tampered with by the developers which causes the aforementioned issue. The Android Mic Fix, as the name suggests, aims to fix this problem with the help of the “resetprop” tool to modify your build.prop file.
Hit thanks if I helped you.

Interesting, got to try it.
Thanks Dev.
Nice! Thanks for that, now about the Mod
The App force close, is that normal? Are we supposed to edit the settings in the System Files?
Edit: Yes
Is there any apps SoundAlive? Cause I don't see it, but SoundAlive.xml is there.
For sure, my existing Dolby atmos crash.

Ah, got it
The sound really got better.
But bootlup on the latest version. Previous worked.

This is an amazing mod. Using 4.2 on one plus 7 pro Android 10. The thread looks dead. I stumbled across it in Google search. Instructions need to be a bit clearer. It also won't install unless you install the sound alive APK. I chose the version closest to the date of 4.2 It really is night and day difference. Much better than the usual distorted sound of viper (for me). Using with digital plus. Sounds stronger than Atmos. Thanks.

[Magisk] [Module] STEREO-HIFI-PREMIUM to AOSP 9.0

STEREO-HIFI-PREMIUM only for AOSP 9.0.
Author Big_Brazer , I just tested and made it a module for Magisk.
This is not a port , the mod is made entirely on the aosp 9.0 files of our device.
Not to be confused with the stereo mod for two speakers, this is not about it.
*
v1.4
The sampling frequency of the audio is increased to 862000hz
Audio frequency up to 32bit
The Bluetooth A2DP driver now has support for 128bit 768000hz.
Improved effects surround_sound the back of the stage and improved audio depth.
===
v1.5
Activated Auro 11.1
*
It is recommended to install on a clean system without any audio modifications in the form of Dolby, ViPER4Android and others because they still cut the quality of the signal under its configuration.
P.S. perhaps they you more not will need.
How to check if it's working ???
v1.5
Activated Auro 11.1
For what is this mod ? I just edit mixer paths to 92 lvl instead of 72 and sounds wonderful .

Stock Q no longer provides Audio Enhancer&Equalizer

Hi,
I send Feedback about it to Xiaomi and they said this:
"Dear user,
I am the Xiaomi user feedback group. The feedback about the Equalizer. Due to the adjustment of Xiaomi business, the Q version no longer provides this function, which is inconvenient for you."
So dont expect it on the future versions.
Solution for missing sound setup.

Not that the stock equalizer that came from Android Pie was any good. We just need people to try and revive the old DogsBark team (Noozxoide Laboratories) and make rootless DSP. I have nothing against Viper, don't get me wrong, on my other device I use Viper Audio, root and all that stuff... but sometimes you just need to stick to the old user/non-dev ways. I am sure it's possible, the problem is the financing and the will to do it. For me, the app developed by them and last updated in 2013 worked like a charm on many devices... except this one, since november update... That's when the problems started to appear.
Since then, I've been looking not just for an equalizer, but a self contained DSP pack that would work better and guess what, nothing's there... nothing except apps with built in function (which by definition are not system wide) and crappy adware.
As for the "Xiaomi business" this really shows me that Xiaomi really gave up on the development of this device, and ALL stock Xiaomi apps will be gone, replaced by Qualcomm's apps... and I don't ever recall seeing any DSP coming directly from Qualcomm.
----------Later addon----------
While the PRO version of Noozxoide EIZO-Rewire PRO has the problems mentioned it seems that the second software Noozxoide EIZO-Rewire Elemental which works even better is still compatible and working just fine on Android 10. Right now it's in testing and benchmarking... which is not an easy job to do, but as long as I love quality music I will do it and post results/download links for it.
-----Download Software-----
Download the Noozxoide EIZO-Rewire Elemental from HERE.
-----Testing abstract-----
For the following tests, were done using only hi-res audio (FLAC/ALAC 96khz 3mbps) files and 320kbps mp3 files so results may vary compared to what I tested here. Remember that streaming services use low bitrate/extremely compressed content.
---Test Speakers---
Internal audio speakers has a good response, bass is there audible, resolution is good, in this case I cannot post any reference to advanced graphs since they are irrelevant in this case.
The best settings (for me) are posted in the first screenshot here. While this is my recommendation, the software doesn't go overboard and keeps the audio quality in control. While testing all the test tracks which varies from Rock/Metal to Acoustic to a more aggressive dubstep there were absolutely NO cracks and pops in audio output from the speaker (which is a result of poor equalization/frequencies outside the speaker range).
---Test Line-Out/Amplified output---
Headphones (because of my current limitations of testing - a conclusive test would be source file vs. processed audio output and multiple headphone test - in ear, open back, ported, etc) were only tested with 3.5mm jack Apple EarPods which are well known to have the best consumer grade frequency response I found that the 2nd attached screenshot works best (for me). While some FLAC files with really deep bass (about 6-10Hz) totally overrun them (and not the Qualcomm audio processor) I would say that this DSP (VSP) works just fine on our devices.
I don't know if I should leave a placeholder here for the advanced, audiophile grade, passive amplified headphones.
---Test Wireless Audio---
Bluetooth and wireless media. Works just as expected. Test were done only with a Nokia BH-503 headset (couldn't test on the car, and neither did I want to spend time going to the car and test it on the BMW Pro-Logic system) but on those headset it made them literally vibrate on the ears, extremely good quality sound, deep bass, crystal clear trebbles and warm mid-tones. Again, I didn't manage to get a single crackle or pop on the speaker drivers which means the equalization done by this engine is sensible and perfectly limited/compressed. The settings I used are posted in the third screenshot.
-----Conclusion-----
The solution posted here works fine, while extensive testing the app still shows that is consumed 0% battery, so the battery drain is minimal.
The application works perfectly after reboot and closing from the recents screen, there were no modifications done/or excluded from the battery optimization screen.
This application is not a booster, this application is a DIGITAL SOUND PROCESSOR controlling the Qualcomm core (was built for this back in the day) and upscaling the audio resolution.
-----Q/A-----
Q: Does this app require any tampering with the system?
A: No, this app is installed as a normal app from the link provided (Play store link)
Q: Does this app work as a system wide equalizer and integrates in other apps?
A: Yes, yes it does, and from my testing it works with all media players (the equalizer option opens up the app), Youtube, Games, etc.
Q: Does this app consume system resources while processing?
A: Yes and no. Of course you need system resources for processing but they aren't that intensive at least for MP3 processing but for FLAC/ALAC processing things get a little more frisky as shown in the 4th screenshot attached.
Q: How's the battery drain overall with FLAC and MP3 playback?
A: Depending on the method of listening the drainage is different, but even on Bluetooth the consumption didn't affect my battery overall.
Q: Does this enable AptX?
A: No. This has nothing to do with that. But while AptX and SBC are not that different in base audio quality, this pushes the codec to 328kbps and upscales the audio to a resolution of 48khz which is ideed great for maxed out mp3 quality over Bluetooth, which again is based on the source files.

Hello, I'm going to present to you a method to enable hi-res on the DAC of the Xiaomi Redmi Note 9' family.
The procedure will allow to you to use the full potential of the WCD9385 DAC present (at least) in the Snapdragon 720G.
Indeed, this chip can go up to 32 bits @ 192Khz for PCM stream and can decode natively DSD. Moreover, this chip have a THD+N (Total Harmonics Distortion + Noise) at a level of -108dB, but all audio tests of Xiaomi's phones mesures a THD+N about ~ -96dB, which is the noise floor of 16bits, logic cause by default, this chip is configured to only output in 16 bits mode.
I have setup, tested and experimenting myself on my own phone (Redmi Note 9 Pro - Global Version - MIUI 12.0.2.0 QJZMIXM) this method.
Due to some ROM similarity with other smartphone models in Xiaomi, it will probably works with other smartphones than the Note 9's family, but i will probably need some adjustments if your phone use a different DAC or scheme of audio configuration files.
Before anything :
I'm not responsible of any damage, malfunction or brick that you can do by applying the method. In general, if you don't know what are you doing, just don't do it !

Pre-requests :
1) Install ADB, Fastboot and Google ADB Drivers (if you are on Windows)
2) You need to unlock bootloader with Mi-Flash-Unlock (THIS WILL WIPE ALL YOUR PERSONAL DATA, MAKE A SAVE BEFORE STARTING ANYTHING !)
3) Install TWRP for Redmi Xiaomi Note 9
4) You need to root your smartphone with Magisk and install the boot image in fastboot mode that it will give to you.
5) Install ABD_ROOT and ENABLE_ENG Magisk's modules (it will give you the possibility to get root access in ADB) and turn them on for the next device reboot in Magisk App
6) Install MakeSysRW in TWRP (without it we can't remount /vendor partition in Read-Write, and can't touch system's files)
7) Strongly recommanded but not necessary : install Sample Rate Checker from Google Play (with this tool, you can check if the DAC has correctly been set in "HI-RES" mode)

Get your phone tuned for Hi-RES :
1) One all of those pre-requests are effectives, you need to get a terminal with adb working (smartphone connected to your PC and debug mode activated) and type :
adb shell mount -o remount,rw /vendor
If you get no errors, you just mounted the partition /vendor on your phone in Read-Write mode, this will allow you to get to the next step, otherwise, i strongly recommand to you to check if you have correctly done all the pre-requests i have described.
2) The next step will save the current audio configuration of your phone (in case you want to return to it for some reasons), still in a terminal window, type :
Code:
adb pull /vendor/etc/audio/audio_policy_configuration.xml ./saved_audio_policy_configuration.xml
adb pull /vendor/etc/audio_io_policy.conf ./saved_audio_io_policy.conf
This will download from your smartphone to your computer the current audio configuration files and save them under "saved_audio_policy_configuration.xml" and "saved_audio_io_policy.conf" in your current directory.
3) Now we will upload configurations files that i've tuned myself, in first case for my personal use.
What changes I've made from the OEM configuration ?
PRIMARY_OUTPUT was in 16 bits @ 48kHz => changed to 24bits @ 192 Khz
RAW_OUTPUT was in 16 bits @ 48 Khz => changed to 24 bits @ 192 Khz
DEEP_BUFFER was in 24bits @ 48 Khz => changed to 24bits @ 192 Khz
Wired Headset, Wired Headphones and Line comes from 16 bits @ 48 Khz, have all been tuned to 24 bits @ 192 Khz
Moreover, i have not touched the integrated speakers because they will not profit to go into 24 bits mode or with an higher sampling rate, and you will get more energy saving by let them as they currently are.

If you check the configuration, you will see at points that I tuned this : samplingRates="48000, 96000,192000"
EDIT 22-04-2021 - Few hours after the first release :
I have done this to let Android choose by it's own the sampling rate, because i have seen some sort of clipping on LINE output with OGG (vorbis) files (I assume it will be the same with destructive formats, such as MP3, but it's at least with OGG files) at max volume with very loud musics, i thinks if you set strict resampling at 96 or 192Khz, due to fast algorithms in Android Audio, it will generate some sort of distortion and, if your music is loud enough (and you are at the max volume), it will go over 0dB and clip. So I've maintained sampling rate at 48Khz, and it seems to be well, but if you have some clipping, please tell me in your reply, i will investigate further.
The clipping was effectively done by a resampling mismatches with two configurations files :
audio_policy_configuration.xml (the one that I modified originally)
audio_io_policy.conf
Sampling rates mismatches in audio_io_policy.conf because I left them to the OEM configuration, now it's fixed.​

You can get my configuration file in the files attached to this post, unzip the files in the current directory where ADB running, then send them to your device :
Code:
adb push ./audio_policy_configuration.xml /vendor/etc/audio/audio_policy_configuration.xml
adb push ./audio_io_policy.conf /vendor/etc/audio_io_policy.conf
This command will overwrite your current configuration files, once again, please be sure to have saved OEM configuration file on your PC !
4) Reboot your phone, and enjoy ! Now you can check with Sample Rate Checker the configuration, you will see something like this (it can be slithly different depending on what is plugged to your phone when you're start the app, in my case i have plugged my phone to an amplifier, so LINE_ANALOG has appears):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
As you can see, AudioManager is in 192Khz mode, BUILTIN_EARPIECE correspond to the front top speaker usesed for private communications, and BUILTINT_SPEAKER is the bottom speaker, both of them have remain untouched.
The most interesting is LINE_ANALOG, corresponding to the phone plugged to a LINE output (a high impedance receiver, such as an amplifier), you can see the different Sample Rates supported, up to 192Khz, and Encodings is ENCODING_PCM_FLOAT corresponding to 24 bits (you can compare it with BUILTIN_EARPIECE and BUILTIN_SPEAKER that they are in 16bits mode).
EDIT : i can't attach the file to my post, anyway i sent it to mediafire and there is the download link

If you have any comments, any remarks or want help, do not hesitate to ask.
22/04/2021 - Few hours after the first post :
I have discovered that the mysterious clipping isn't present when i plug/unplug the phone for few seconds, before appearing.
After some research, try and retries, I've found the problem : the file audio_io_policy.conf
In this file is listed all outputs present in the audio_policy_configuration.xml, but i found that all outputs have a fixed 48 kHz sample rate, which don't match with the concatenated ones in the tuned file.
Concretely, internally the sample rates don't matches, and streams (over)sampled above 48 KHz are some sort of clipped.
So I have concatenated samples also in audio_io_policy.conf, and now it works well with all types of musics.
The first post will be edited with modifications that you need to do with the file audio_io_policy.conf
06/13/2021 :
Xiaomi released an update (MIUI V12.0.1.0 - R****M) which introduce Android 11.
My mod is still perfectly working with this update and Android 11 without any modifications !
So, you can still follow this tutorial to enhance your device audio quality

Your audio_policy_configuration.xml has '<globalConfiguration speaker_drc_enabled="true"/>', and this means DRC (Dynamic Range Control) has been enabled on your all audio outputs. This is the reason the THD+N of your device is larger than that of usual hifi devices. Try replace the true with false in your configuration.xml file.
If you like, see maximizing the audio quality of bluetooth.

Thanks for your reply, i tried on my device but i don't know if I can hear a difference between before and now or if is it a placebo effect.
Android's audio configuration are poorly documented, what does exactly DRC ?
Thanks again for this tips, it will be added in the mod
The sample rate of AudioManager always 192kHZ, not fit the song dynamically.
Even we ignored energy saving(96kHZ, 48kHZ, etc), but how to handle 44.1kHZ case?
SRC still exist in this case right?

Yes it doesn't fit the song dynamically (at least them which are lossy formatted songs), but this is the android default behaviour, and instead of putting anything in 48kHz (which can be bad for all musics sampled over 48kHz), with my mod it resampling everything at 192Khz, which can avoid frequencies repliement (cf Shannon-Nyquist's theorem) and can be benefit for the DAC's internal logic and post-treatments.
Anyway, some music players on Android define the "passthrough" flag on lossless formats which tell to Android to not upsample.
In 24bits float, upsampling is very precise, and there's be no distortions audible (if there distorsion, it will happen only close to the noise floor, which is inaudible anyway), so you can consider your 44.1Khz to be EXACTLY the same if they are upsampling to 192Khz.
If it was 16bits, I will not tell you the same, in 16bits, the noise floor is at 96Khz, and there's much more conversions errors in Integer than floats, and much more in 16bits than 24 bits, so in this case, it can be destructive.

Thanks!
Actually I am using Apple Music beta version which supporting lossless(even hi-res) resource. What can I do to "passthrough" upsample of Android? I saw a module called AINUR NARSIL in Magisk, is that work?
Two most common lossless formats in Apple Music are 16bit_44.1kHZ and 24bit_96kHZ. As you said, 16bit may cause serious problems? BTW, what's the difference between AUDIO_FORMAT_PCM_24_BIT_PACKED and AUDIO_FORMAT_PCM_24_BIT?
If 192kHZ works fine, how about 384?

You can't force to use the passthrough flag, it only depend on the music player implementation, how it use the Android's Audio layer. Apple Music can decode hi-res resources, but it not guaranteed that it use the passthrough flag behind. Anyway with my mod, even it doesn't use the passthrought flag, it will be upscaled to 192Khz which is sufficient for every hi-res listening.
Remember that the passthrough flag only tell to the Android Audio layer to not resampling the audio, which can be bad with music with a low sampling rate (as 44.1Khz or even 48Khz), cause there's no margin for audio processing in the DAC or high frequencies already in the audio source file.
I don't know about if the AINUR NARSIL mod can force the passthrough, the better is to test it yourself i would say

Yes 16 bits may cause interpolations errors only if the destination rate isn't a multiple of the original rate and only if Android make the upsampling by maintaining the output level if the destination sampling rate is a multiple of the original one. This is a bit technical, and I don't know what Android decide and do, but in the worst case, yes, 16 bits integer sound makes more interpolation errors cause 16 bits is less precise than 24 bits float and makes more rounding errors.
For your last question, AUDIO_FORMAT_PCM_24BIT doesn't exist.
According to https://android.googlesource.com/platform/hardware/interfaces/+/master/audio/common/4.0/types.hal :
Code:
/* Subformats */
PCM_SUB_16_BIT = 0x1, // PCM signed 16 bits
PCM_SUB_8_BIT = 0x2, // PCM unsigned 8 bits
PCM_SUB_32_BIT = 0x3, // PCM signed .31 fixed point
PCM_SUB_8_24_BIT = 0x4, // PCM signed 8.23 fixed point
PCM_SUB_FLOAT = 0x5, // PCM single-precision float pt
PCM_SUB_24_BIT_PACKED = 0x6, // PCM signed .23 fix pt (3 bytes)
So there's just two different version of representing 24bits data.
You should take a look here, you'll probably learn some tips on how Android handle audio data

Much to learn.
One more question: your Sample Rate Checker showed that "LINE_ANALOG Encodings" is AUDIO_FORMAT_PCM_FLOAT. I got same result with my earphone. Our related setting should be AUDIO_FORMAT_PCM_24_BIT_PACKED. Thus i am confusing about that. Do you know why?
Here is my log and its screenshots. Some FLOAT words also appeared in it. Looks like Qualcomm handle audio by FLOAT format. I don't know if they have similar reason.

AUDIO_FORMAT_PCM_24_BIT_PACKED is the sub-format which is the float format in Android (as showed in my last reply), it contain only factional part and no integer part.
AUDIO_FORMAT_PCM_FLOAT is just a short alias which refer to it.
So, AUDIO_FORMAT_PCM_24_BIT_PACKED is strictly equal to AUDIO_FORMAT_PCM_FLOAT.
Apparently on your device, is it already setup to handle hifi audio in the record processing as well as the output, everything is in 24bits (float) @ 384KHz, which is very nice !
Which device is it ?

I can see the THD+N (Total Harmonics Distortions + Noise) is at -109dB for the WCD9341 and at -108 for the WWCD9385, which is exactly the same (you can't hear the difference, i dare anyone to tell me otherwise).
Don't refer to the "Playback Dynamic Range", which don't represent what is it outputted (you have to add the noise and the harmonics distortions).
You're very right to use it as a everyday hifi player ! I'm very surprise that Xiaomi has think to set the DAC in a hi-res mode by default. I'm wondering why they haven't do the same for their new devices .

Actually I also changed configs as your mod and turn more items else to 24bit/384kHZ to ensure hi-res works. However, i don't know which features are essential for me.

"hifi_playback" is just an unused output which isn't routed to anything, so don't mind about it.
About your sampling rate change to 384kHz, this will not gonna set it to 384Khz cause you don't change the file "audio_io_policy.conf" where is the i/o configuration (currently, your configuration can cause some volume saturation as it done the first time I tried my mod on my device).
You need to set 384KHz as well in this file.
Moreover, is it useless to set the USB output over to 192Khz, I don't know a device in USB which can handle 384KHz audio on a USB connection.
However, I don't think there's a reel benefit to set the DAC to 384KHz, I mean the maximum sampling rate in PCM hi-res file is 192Khz (still rare actually) and I never seen anything beyond this value. Typically a hi-res file is in [email protected]
So what i'm trying to say, is that a change from [email protected] to [email protected] is beneficial, for many reasons (16-->24 bits, integer mode to float, increasing sampling rate), but passing from 192KHz to 384KHz is, in my opinion, completely useless.
Moreover, a value that high can increase the risk of causing some jitter (which normally can't happen even at 384Khz, but theoretically the risk increase).
And finally, you'll consume more power for nothing.

My system is MIUI11. A file called "audio_output_policy.conf" in same place which has the same content as a part of your audio_io_policy.conf. I've edited it and other file called "audio_policy.xml" in case.
Jitter looks getting higher in log but I don't know if I can hear it apparently.
Even I removed all energy-cost-optimizing-strategy on my music app to enhance stability of performance with 384kHZ. The battery cost is still acceptable.
Indeed, it makes me feel little bit weird when adopting 384kHz. All I do this is considering SRC from 44.1kHZ. Higher sampling may cause more reasonable curve in analog signal. However, it depends on algorithm and may cause other problems like harmonic wave and jitter. So it's an experiment and a trade-off. I will go back to 192kHZ if got nothing on 44.1kHZ files after comparing.

I'm making a USB Sample Rate Changer script like bluetooth LDAC and usb-samplerate-unlocker (up to 386kHz and even 768kHz). If you like, see my github USB Sample Rate Changer and usb-samplerate-unlocker.
Update 08/07/2021 :
Hello guys, i have made a magisk module with this mod, it's currently on submission stage and it will be, normally, fully available in the magisk module repository (the "market").
With this magisk module, the mod will be systemless and will no require tricks to hard-modifying files on the device !
I'll keep you informed about this !
Great work.
I need to do the same in my K20 pro (Raphaelin), for the apple music lossless to use the inbuilt hifi dac
