It worked! Now the question is, are the audio effects that we disable (delete) something important?

I have deleted the audio_effect.conf to prevent conflicts with Music FX.

I totally understand that, but are these effects important for the good quality of the sound? I saw that some of the effects included a VoIP handler and bass booster, is removing them going to have any noticeable negative impact on the sound quality?

No. I've been running V4A using this method for over a month now and sound quality has definitely improved in every regard. Flash away.

Just a quick clarification, do we just need to flash it or do we flash, install V4A, remove music fx, delete audio effects... Etc?

Awesome! I just flashed, but it doesn't appear that V4A installed. Reflash?

This does work with 6.0.1 as well for anyone wondering

I got viper and android pay working using eggydrums method here: https://www.reddit.com/r/Nexus6P/comments/3w9fzb/guide_install_viper_audio_with_systemless_root/
You do have to delete /system/vendor/etc/audio_effects.conf as stated in the notes and if you use SuperSU 2.62 you will have to delete /su/xbin_bind folder as well.

I should also note that in order to get viper to start processing I disabled musicfx and removed viper from doze and rebooted. Not sure which one made it work but it's processing now.

+1 here

I got V4A working, however even with Power Saving driver it's draining at a rate of 1% per minute of audio. Before I installed V4A I didn't have this battery issue. Literally minutes after installing V4A, the battery drain while playing audio happens. Nothing else has changed.
Has anyone else had terrible battery when using V4A?

It seems like the developer still uses XHiFi as well.

I'm on the January update using super su 2.62 and I have everything showing supported, yes, processing yes, but there is no sound playing. The neon enabled is the only no.

How did you move the script to the su/bin folder? I keep on getting permission denied
Edit: nvm, i guess ES file browser thinks it's too good for systemless root... used another root explorer
UGH! but i still can't delete or rename audio_effects.conf, or even change permissions

I installed this program and this mod and it's all right with me.
NEON working, working convolver, no battery problem.

Anyone get this to work on systemless?

[OUTDATED] Sound Mods Working +Install guide

/////
THIS GUIDE WAS FROM THE NOVEMBER SECURITY PATCH ON NOUGAT!!! DO NOT DO THIS IF YOU ARE ON OREO CAUSE YOU WILL LOSE ALL SOUND!
IF YOU WOULD LIKE TO USE VIPER ON OREO/PIE DEVICES. PLEASE USE THE MAGISK MODULE AND/OR FIND A BETTER GUIDE WITH A COMPATIBLE ZIP
//////
Okay I have confirmed that sound mods work on the Moto z2 force with no issues whatsoever many probably know that
How to Install:
1.
make sure you have root and TWRP installed on your Moto Z2 force
2.
download this version of A.R.I.S.E.
https://androidfilehost.com/?fid=457095661767141554
3.
Place the zip file in the Internal storage of your device (so its easy to find)
4.
Boot into TWRP recovery and click install
5.
Find the file you put in your internal storage named;
ARISE+Deuteronomy+2.94+Modular+AROMA+Installer.zip
And then swipe to install
6
An install wizard should appear and assuming that you haven't used this before select easy mode on the wizard and make sure you have it set to "install core engine then modules" and spam the hell out of the next button besides those 2 things
7.
TWRP screen should appear and you should boot into your device like normal
8.
ENJOY
SOME NOTES:
A.R.I.S.E AM3D DOES NOT WORK BUT OTHER THAN THAT EVERYTHING ELSE IS FINE
Update: DO NOT ATTEMPT TO INSTALL MAGNUM OPUS IT WILL FAIL

Man.. I was going to try ARISE, but with all the concerns that I couldn't restore a nandroid because of data partition encryption, I just said screw it and I installed the v4a 2.3.4 module right from Magisk, and it works great with both USB Type-C to 3.5mm and Bluetooth.
I don't know if anyone's noticed or not, but Oreo has an entire section on Bluetooth audio protocol under the development options. Things like sample rate, bit rate, etc etc. I do know that v4a works with all protocols (SBC, AAC, aptX, aptX HD and LDAC), but if you up the sample rate to 96khz, it will NOT process. I usually use 48khz and it sounds great.

I installed arise and lost all audio on device . I don't know if it's a setting or something in aroma I should not have added or if it's viper settings I messed with .
I need to uninstall this how do I
Or how do I get sound back this is weird

Yes sir, I am. Since I got it working, I haven't touched anything in fear that it'll stop working. I haven't even made a nandroid. Twrp isn't installed, I just booted in it from adb.

Right on! I was also advised not to install TWRP. I flashed it and it seems to be working so far. Having other issues though like my camera and flash (flashlight) don't work now since installing magisk or the v4a which one I'm not sure but I assume magisk.
3/12/18 Update: camera and Flash are working properly now after a wipe Dalvik, cache and reboot.

Is anyone else having issues with viper4android working intermittently on Oreo? Sometimes it works but mostly it doesn't and I have no way to control it, toggling the switches does nothing and it doesn't matter if I reboot or not. It does work sometimes so I know the drivers are installed, and I've tried a fresh install a few times using the 2.3.4 version and the newest 5.0 version which produces the same result.
Is there a setting in magisk or Viper that I need to apply to to get it working seamlessly? I have systemless hosts check-in magisk already for ad blocking. There's got to be something I'm missing here. Any help is greatly appreciated thanks!

I was having this situation, the I disabled the music FX and it's gone for now

Flashlight stops because of selinux

Dolby Atmos for oreo works fine without any problems. You just have to find the working version in the last few pages of the mod thread.

Was able to get the latest ARISE, plus V4A, and Dolby ATMOS Oreo from guitardedhero working. I'm using SuperSU as I'm not a fan of Magisk. Flashed the latest ARISE, including the V4A 2.5.0.5. Crap, I made sure V4A opened and checked that the drivers were installed. But I may have flashed the ViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apk over the ARISE loaded v4a apk....? Try to see if the loaded apk works first. If not, flash Nougat_IO_test_fix.apk over: ViPER4Android_FX_v2505.zip Anyway, use this to set permissive: The.SELinux.Switch.ver.6.0.3.build.603.apk. Reboot. ARISE libs will be there and V4A should work. Sometimes you have to turn off the main power button for the V4A mod, go up to the corner button and exit. Clear out anything in recents. Then open V4A back up, and enable the power button. If music is playing, you will hear the change.
Ok.....Dolby. Go HERE and download the normal zip. Thank the dude, he's done a lot for us audiophiles. Flash it. Reboot. Apps will be there, and will likely forceclose. You have to extract the dolby zip and copy the libs from the dolby/lib and dolby/lib/soundfx files and paste them in the related folders in root /system/vendor and system/vendor/soundfx. You need to set the permissions to rw-r-r (644). Now save/reboot. Apps should work. I'm betting other libs/files weren't installed either, but just those got Atmos working, working well. Still looking through things and will verify later what else wasn't placed.:good:

Quick Question, I have used ARISE and Viper before and really like them but this is a Software Mod. I would just like to clarify that this Software Mod works on the actual Hardware Mod and if it does, does this Software Mod work on the Hardware Mod using a Custom ROM or Kernal? Can anyone confirm that yet?

Sorry about this... You may have to back up your internal then flash back to stock. This guide was from when our device was still on nougat. For Oreo I need you to install the module from MAGISK or find the magnum opus zip

Hi, thank you for this post, but I wonder is it possible to install this without root and magisk?
I have Redmi Note 5 AI with global stable MIUI 10.3.1.0 based on PIE. I have also unlocked bootloader, but I don't know to work with magisk.
Is there any solution to install this Dolby and enable it without root?
For example, can we do this via TWRP?
Please, advice?
Thank You in advance :good:

If you are getting Force Close's with selinux enforcing then change it to permissive. With attached Magisk module.

[GUIDE] How to Make Audio Mods Work Amazingly Well

I am an audiophile and I make it a point to use audio mods whenever possible. That being said, the audio mods that I've tried and worked amazingly well are Viper4Android and Ainur Sauron, but you will also need Audio Compatibility Patch and Audio Modification Library to make things work so seamlessly.
That being said, I get to see a lot of people complaining about Viper4Android being too buggy in that after every restart, it asks for the driver to be installed again, etc. Well, I have clean flashed/dirty flashed plenty of ROMs now so I can honestly say that my method works.
So, what is my method for installing all of the audio mods I mentioned earlier? Well here are the steps:
1. Install Busybox for Android (in Magisk Repo)
2. Install Audio Compatibility Patch. It now comes with a multi-option installer, so you want to Select NO to the first option then choose Vol + (Patch New Logic). Select NO to the second option and then use Vol - (remove Volume Listener Library). This is done so that your audio won't crackle. You can skip USB Dac if you're not using it and you should choose NO at the last option (library workaround).
3. After Installing ACP with the chosen options, proceed to install Ainur Sauron.
4. Once that is done, install Audio Modification Library. After AML, DO NOT REBOOT YET.
5. Download the Viper4Android 2.7.1 APK here: https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx . I find this to be the best iteration of the module since it is not buggy at all. Once that is installed, run the application and it will prompt you to install drivers for the first time, choose OK and then allow it to reboot. (Note: after installing this, a Magisk Module will be created automatically)
At this point, all of the audio mods should work in unison. Do not toggle anything else in Viper4Android but the main interface. This means that do not go to the settings and toggle anything. Just configure the audio options as per your liking.
6. Currently, the setup will bork BT audio which means that there is no sound that is going to come off of your BT speakers or headphones. What you need to do to fix this is as follows:
a. Rename "audio_policy_configuration.xml" in "/sbin/.magisk/img/aml/system/vendor/etc/audio" to "audio_policy_configuration.xml.bak".
b. Copy the audio policy configuration xml file from "/sbin/.magisk/img/aml/system/etc" to "/sbin/.magisk/img/aml/system/vendor/etc/audio".
c. Restart the device.
Additional Notes
a. When dirty flashing your custom ROM, allow the modules to recoup itself. In other words, do not touch anything until everything is back to normal (or after 5 minutes from dirty flashing).
b. If you happen to uninstall Ainur Sauron (or Narsil), I find that it usually uninstalls viper4android as well. If that is the case, uninstall Sauron and then click the viper4android app from the drawer and allow it to install drivers again.
c. In some devices, the BT workaround is no longer needed. However, I find that for the Pocophone, the workaround is still required. I guess you just have to test it for yourself if it works right off the bat or not.
d. Audio compatibility patch (remove patch logic) actually enhances the volume and the sound quality of the Poco F1. I cannot test this on other devices since I do not have another phone, but you can try and see if it works for you. (thanks to @Jonas G. Morsch for this).
e. If you are going to try Ainur Narsil, I suggest that you do not install viper4android anymore since it provides a great listening experience right off the bat. You can still install v4a, though if you really want it (The same procedure applies).
f. If you are using a custom ROM that has a built-in "AudioFX" app, you need to freeze it using Titanium Backup or similar apps for Viper4android to work. Thanks to @mikedavo for this tip.
g. If, after following all of the above instructions, and you still experience random driver issues or bugs, I suggest that you do a clean installation of your ROM and do the entire steps again. If it still presents the same error, I suggest that you hop on the Viper4android telegram channel to address your concern so that the dev can fix it.
h. Attached below is a profile converter, so if you're using the old version of Viper4android, you can use the attached file to convert all of your profiles to supported presets.
That's about it! If you have questions, feel free to drop them below. Happy listening!

man just what i needed. thank you very much. will try it later. :good:

Point 6 should be fixed. Possible a failure in Poco firmware or something. Use latest AML from Magisk repo. Also install all modules via magisk manager by now. Seems there is an issue and we are working in it.
Also I would replace Viper with JamesDSP.
JamesDSP future is bright and expect a tone of new **** in future. ?

Work as a charm in MIUI latest... But Bluetooth is working without step 6
Sent from my POCOPHONE F1 using Tapatalk

Hmm, I just make sure to disable and freeze any inbuilt audio equaliser or fx from custom roms before installing viper and have never had a problem with vipers drivers installing or instability in viper. I also, after installing viper, activate enhanced sound at the bottom of the sound menu in settings and choose my headphones in the dropdpwn, mine are mi inear pro. If I happen to forget to do this, I'll get the drivers need installing message from viper.

Use jamesDSP. Better ****. Has even 24-bit support. Viper just 16-bit. Also our viper guys teamed up with James. So expect some new **** soon.

it doesn't work for me at all, viper keeps asking to install driver and reboots the phone.. again and again

Edit:- This worked perfectly for me even in the Secondary ROM with the following changes. V4A 2.7.0 instead of Latest 2.7.1 probably because I'm using Magisk 18.1 and V4A kept on asking to install driver even after reboot so I had renamed the MusicFX.apk in the System to MusicFX.apk.bak.
@BenParz Thank you very much for the guide.
This trick doesn't work with MultiROM for sure.

Will viper work with a bitrate of over 48k? My headphones us 96k which doesnt work with the buggy v4a i use, but its the only version of v4a that actually works at all for me (will try your way of installing later)

I'm not using MultiROM. I'm on PE latest build

I've created a monster hehe. Ainur Sauron also installed

BenParz, i can't thank you enough for this! the choppy audio after installing Viper was making me crazy.
I'm running Lineage OS 05/18/2019 + nano gaaps
After mess around with this modules i got other way:
1 . Install Audio Compatibility Patch. It now comes with a multi-option installer, so you want to Select NO to the first option then choose Vol + (Patch New Logic). Select NO to the second option and then use Vol - (remove Volume Listener Library). This is done so that your audio won't crackle. You can skip USB Dac if you're not using it and you should choose NO at the last option (library workaround).
2. Download and install Viper4Android 2.7.1 Magisk Module here: https://zackptg5.com/downloads/v4afx_v2.7.1.0.zip .
More info : https://forum.xda-developers.com/android/apps-games/app-viper4android-fx-2-6-0-0-t3774651
3. Fix BT:
a. Rename "audio_policy_configuration.xml" in "/sbin/.magisk/img/acp/system/vendor/etc/audio" to "audio_policy_configuration.xml.bak".
b. Copy the audio policy configuration xml file from "/sbin/.magisk/img/acp/system/etc" to "/sbin/.magisk/img/acp/system/vendor/etc/audio".
4. Go to ViperFx and install drivers, Viper will auto Reboot!
I'm probably cutting some corners here, but i got no problems at all this far.

Have you tried whatsapp voice notes?
Are they making crackling sound when app is minimized or screen is off while playing voice note?

Thanks a lot for such an easy guide.

Well, you can actually change the Bluetooth bitrate setting in developer options. Doing that allows me to use V4a on my sony BT speaker (which uses LDAC).

Yeah, Whatsapp on Lineage crackles no matter what.
I'm dealing with this problem since my Zenfone 2 with Lineage 14 and no audio mod whatsoever, but never cared too much, because when i rarely listen Whatsapp audio files i do in foreground, and using the earpiece, . I also use telegram for 95+% off my conversations this days.

Hi Again!
After some time of testing, i think i got it how to use Audio Compatibility Patch (1.7.3+) with Lineage OS properly on our device:
Skip audio_policy patching?
- No
Patch flags or remove selections?
- Remove (old logic)
If patched the audio gets worse/lower on speaker/jack.
Would you like to skip notification helper?
- No
Remove notification helper effect or volume listener library?
- Remove volume listener library
Would you like to skip usb policy patching for usb dacs?
- Whatever
Use library workaround?
- No
If used causes bluetooth routing problems.
No Audio Modification Library needed.
After this sequence, my earphones,bluetooth and speaker worked fine with ViperFX 2.7.1, especially the jack, witch was really quieter and muffed before.
Can you guys try it out?

AudioModificationLibrary (AML) has been updated to 2.4. we've also updated unity modules. Everything should work now. Viper, James, Sauron and DTS.
At least on latest MIUI pie betas there should be no Bluetooth bug or anything.
There was a question regarding viper and above 48k.
Viper can just process up to 48. We've released yesterday the new module with DTSultra port. This is capable of up to 96k.

What about bluetooth on PE and other custom ROMs?

[Guide] [No Root] How to unlock Dolby Atmos equalizer (OxygenOS 10 Only!))

Hi everyone!
Some time ago I was looking for a way to get a system audio equalizer and I accidentally found an application that can be very useful for all of you!
As you know, OnePlus 7 Pro has Dolby Atmos support, but controlling it is limited to 3 presets, we cannot control the sound ourselves, we can only do it after connecting headphones, previously I had the Galaxy S9, which also has Dolby Atmos, but there is full access to the equalizer that significantly improves the sound quality, which is why I was surprised that OnePlus does not give us such a possibility, as far as I know equalier for the speaker was once available in the global version of the software, but later they removed it in the update.
It turns out that we can control Dolby Atmos ourselves, only the phone settings application does not allow it, but you can work around it!
In these few steps you will get full control over Dolby Atmos and even be able to turn it off:
Step 1: Download "Minimal ADB and Fastboot" to your computer, then enable USB debugging on your phone, then connect the phone to the computer and run the file "cmd-here", which you will find in the folder with ADB and Fastboot.
Step 2: Now you need to debloat the Dolby Atmos system controller, to do this, you must enter the following commands in the fastboot console: (don't forget to allow USB debugging on your phone! After connecting the phone to the computer, the phone will ask you if you allow it)
Code:
adb shell
pm uninstall --user 0 com.oneplus.sound.tuner
If all went well, then you should see the message "Success" in the console, now you need to restart the phone, when it reboots, you will not find the "Dolby Atmos" in the phone's settings and thats okay.
If you don't do it then the Dolby settings will reset once in a while, e.g. after a system reboot, that's why you had to do step 1 and 2 first before downloading the application.
You can also restore Dolby system settings at any time using this command in adb shell, but I don't recommend doing it if you want to use another Dolby control app:
Code:
cmd package install-existing com.oneplus.sound.tuner
Step 3: Download and install the Dolby Atmos control app on your OnePlus: APKMirror download
And you're done! From now, Dolby Atmos control takes place only in this downloaded app, this is not any typical equalier you will find on Google Play, it is a Dolby system controller which means that it will work all the time, it will not be turned off when you close the app, this app replaces the Dolby system settings you just turned off.
Edit 04.11.2020
Dolby Atmos for OxygenOS 11 can be found in this thread.

I will try this ASAP.... Thanks for the efforts man

Hi thanks for the info
App is working in general but in music tab intelligent equalizer(balanced-warm-detailed) option doesn't make a difference. Is it same for you?

Yes, this one function doesn't work, probably Dolby Atmos on our phones doesn't support this.

Works great with native dolby removed via adb, since i am not rooted at the moment. for me there is a difference in music with warm and balanced, but i am using dynamic with my settings. Thanks man, thanks a lot

Any way to use it on op5 ?

Sound very interesting @Rayekk Is there anyway to use the same in custom ROMs of OnePlus 7? Tried installing apk and it just FCs

Just uploaded the newest Razer phone 2 Dolby UI to apkmirror. Should be live soon.
https://www.apkmirror.com/apk/razer-inc/dolby-atmos-4/
You're welcome. Lol

Tried it on OP 7 pro and OP 8 pro. Works flawlessly! Now I'm wondering if there are any more versions of Dolby from different OEM's which work with our device, maybe allowing for even better sound tuning.

New Version from Razor Phone 2 - Dolby Atmos DAX3_3.5.1.28_r1

Is there a root version of this method too?

Btw, this method is posted in OP7T forum with the same steps long back.
https://forum.xda-developers.com/oneplus-7t/themes/dolby-atmos-equaliser-7t-hd1903-root-t4054999

For me works without uninstalling system Dolby. I just install the apk and works. Thanks

I am just using default Music preset like you can see in screenshot. But its sounds great. Are you sure there is no conflicting audio mods you have installed?
Or even with Poweramp settings it will conflict. Once check those conflicts.

Tested and working on OnePlus 7, I suggest you to post it also on OnePlus7 forum section.
If you prefer I can post it for you (of course all credits will be yours), just to inform the community of this mod.

Is it possible to execute it with terminal ? (Im rooted btw)
Because trying it in terminal i get a nullpointer
