[GUIDE] [A11/A12] [DOLBY ATMOS] [OOS11/12] How to install Dolby Atmos on OOS11/12

Hey Guys
Well after about a year of trying to find a guaranteed way of getting Dolby Atmos to work on OxygenOS 11 i have finally found a way
You will need:
Oneplus 8 Pro
Magisk
Termux (or some other terminal)
Dolby Atmos Magisk Module by @reiyuki
DISCLAIMER: I'M NOT RESPONSIBLE FOR ANY DAMAGE CAUSED TO YOUR PHONE OR DATA AS A RESULT OF FOLLOWING THIS GUIDE.
BY GOING AHEAD WITH THIS YOU UNDERSTAND AND AGREE WITH THE ABOVE
Guide:
1. Download the Dolby Atmos Module
Android 11 -> https://github.com/reiryuki/Dolby-Atmos-OnePlus-8-Visible-Magisk-Module (Recommend Version 6.2)
Android 12 -> https://github.com/reiryuki/Dolby-Atmos-Magic-Revision-Magisk-Module (Recommend Version 2.3 BETA 1)
2. Install Termux from the Google Play Store
3. Remove any existing Dolby Atmos mods that you may have install previously (IMPORTANT!!!)
4. Open Termux and type su bash (grant Termux superuser rights if requested)
5. Next you need to run these 2 commands
setprop dolby.daxui 1
setprop dolby.cleanup 1
6. Next install the Dolby Atmos Magisk Module in Magisk and once done reboot
7. Thats it, Dolby Atmos is installed and ready to go
Known Bugs:
* On some phones the "setprop dolby.daxui 1" command may not work. to workaround this, create a optionals.prop file in the root of your phone storage (/sdcard or /storage/emulated/0 ) and enter in that file
dolby.daxui 1
save the file and proceed with the install as normal
or
download the file attached and extract it in the root of your phone storage -> Thanks to @janres155 for the tip
* Dolby Atmos needs reopening each time you switch audio outputs (Speaker, Bluetooth, Headphones. Just reopen the app and reselect the sound profile you want to use) -> Fixed in V6.2
* Custom EQ settings may sometimes reset -> Fixed in v6.2
* Booting Android into Safe Mode will remove the Dolby Atmos app and you will have to follow this guide again to get it to work again
* Not working in the ColorOS 12 Open Beta (possible Magisk/Module incompatibility with Android 12)
* On Android 12, installing Dolby Atmos may break fingerprint sensor, hopefully a future update will fix this -> Turned out to be caused by Magisk Universal SafetyNet Fix -> Fixed
Thanks;
A huge thanks to the following people (if i miss anyone then please let me know so i can update the list)
@reiryuki - Dolby Atmos Magisk module and commands
@topjohnwu - Magisk
Any questions then be sure to ask
GUIDE LAST UPDATED: 27/08/2022 - Added workaround for Dolby Dax UI not being installed

I'll try it

setprop dolby.mod.ui 1 is only if you using an extended modded UI app. If you don't have, then no need to run this. Written at "Optionals" at my Dolby github for more info.

Ok thanks for this, i shall update the OP, those was the commands i used to get it working so i just listed it there just in case

It works on my phone well,thank u.

Thanks @reiryuki & @dtronics, working well with OOS 11.

Thank you @reiryuki for all the work you've done for this port.
Thank you @dtronics for this guide and alerting me to this module.
I notice that there is no bass booster toggle switch and I would like this option is possible.
1. I'm looking at the optional section for Termux commands and noticed that a lot of them are "not for module powered by Dolby Digital Plus". Is this Dolby Atmos module powered by Dolby Digital Plus?
2. I have no boot loop issue. What's the best way to uninstall this module? Do I need to necessarily run the uninstaller zip file in recovery (can I do this by ADB sideloading)? OR Can I simply remove the modules from Magisk and reboot?
3. Assuming that I properly uninstalled and this module is not powered by DD+, which Termux commands do I add to get the bass booster toggle?
Here's what the guide says...
- Force enable bass boost enhancer with default values (all profiles) (not for module powered by Dolby Digital Plus):
setprop dolby.bass true
- If bass boost enhancer is disabled by default, you can reenable it with the default settings (not for module powered by Dolby Digital Plus):
setprop dolby.bass default

NEW UPDATE. 6.2? any issue?

I can confirm that update 6.2 does work.
You will need to run the 2 commands again BEFORE you install the update.
You know you have done it right when the install log says "Using DAUI instead of OPSoundTuner"

i need to run the 2 commands even this is my first time to install it?
i have op8. paranoid android sapphire alpha 1 build.

Use instruction from first post.

Yes, follow the guide exactly as stated in the first post.
You can ignore the Dolby cleanup command if your room doesn't contain any form of Dolby Atmos but it's best to run it anyway

installation failed still.

Finally working in OOS12 thanks!
P.S for some reason the folder directories to copy the files were:
data/adb/modules/aml
and
data/adb/modules/ViPER4AndroidFX
Figured it out when getting directory does not exit when trying the paths given in first post

TY for this. I had it working 100% on Android 11, but figured I was lost on 12. Only issue I've had is it constantly thinks I'm connected to my car radio's BT after I disconnect, so profiles aren't perfect, but I missed V4Android. Sound quality is night vs day.

Hi there,
after several other methods this one helped me to solve the driver problem. Thanks for that!
Still I have the problem that NEON is not activated. Is there any solution to be found anywhere?
I am using the Oneplus Nord 2T with Oxygen OS Android 12.
EDIT: found solution.

This worked fine for me on OOS13, it works in all apps when the legacy mode is on. However after doing this whole procedure, Dolby Atmos no longer works (at least on the integrated speakers, which is what I only tested)

Didn't work. After replacing files Viper driver is installed loop (OnePlus 10 Pro, OOS 13, C20 (EU))

Hey guy i installed viper works but when i try to use the Convolver and than i click on impulse response. I get this message on the bottom. Anyway to fix this.

The presets install into a different folder. You have to manually move them over to where Viper is telling you it can't find them. Oddly enough, I had to use Terminal to move them. Even Root Explorer with SU permissions got a r/w denial.

Would you be able to link to that fix please.
Also i removed viper and verytime it asks me to install drivers and i do and when i reboot start viper it asks me to do it again. Sorry a little frustrated

Viper4Android That's the thread. Its towards the end. As far as troubleshooting, I can only recommend removing all of the modules and starting from scratch. The steps at the top of this thread worked perfectly for me.

So far nothing i have done has fixed the impulse problem says its not there but the files are in there.

I don't have the link, but Google for Viper4Android 2.7 profiles. A guy has a GitHub page where he's updated them all to work with Viper 2.7. I remember having to download those as the old profiles didn't seem to be recognized.

So afterman trys i was able to get the convolver and impulse response to work. One last question on my old one plus 7 pro i have viper installed with a rom on it and i have this layout wanted to know where i could find this version. Also Its the same version i am using but the layout is different.

I can't spot a difference in the two images. It won't enable though until you toggle the Master Power button to on.

[Bounty] Viper4android fix

Btw, did your phone come or you upgraded to MIUI 13/A12?
Also, you used Xiaomi.eu ROM (Weekly or Stable) with A12?
I'm asking bcs I'm curious, you are quoting to my post for (stock) MIUI 12.5.8/A12 for Lisa, I'd like to know does it work for A12 as well (potentially different folders for audio drivers)

@zgfg
Phone came with MIUI 12.5 based on Android 11, I upgraded it to MIUI 13 / Android 12. Battery life was pathetic on stock for me, so unlocked and flashed the stable xiaomi.eu ROM.
Moved to an AOSP ROM (PixelOS) a week back because I prefer stock Android any day. Battery life is far better than even xiaomi.eu.
But I was able to successfully install Viper4Android on both xiaomi.eu and now PixelOS using these instructions. Although there is one additional step I did which is not mentioned here. I manually copied the audio_effects.xml file to all the locations mentioned in the instructions. You need to copy over the xml file which has v4a_fx mentioned inside the file after the copyright section. It is also the larger size file (7.93 KB for me). Unfortunately I don't remember where this file is originally stored for you to copy it. But you can search for it using a file manager that supports root. You need to copy this file to the locations mentioned after installing Viper plus the driver and rebooting for the first time.
Also make sure that all other audio mods like AudioFX, Dolby Atmos, etc are not installed before installing Viper. I am aware of Audio Modification Library which integrates multiple audio mods, however I have never used it. I suppose it will be even more difficult to install Viper with AML. I could be wrong though. Anyway, for me Viper is enough.

Apparently the problem is with the atom kernel, I say this because I installed the same OS on my two devices (Alioth and Lisa), on Alioth SuperiorOS uses n0kernel, on Lisa it uses atom kernel, and in Alioth a simple installation of the module audio modification library + V4A already worked, a pity that the same does not happen in Lisa, the same already happened in Evox.
Does anyone know which pixelOS kernel it uses?
I'm seriously thinking about going back to Memeui with Lisa, my last attempt will be AOSPA which apparently doesn't use atom kernel.

dude.. i need help
i use Samsung Galaxy A50 and CRDroid Custom ROM Android 11,
i have installed Viper4Android. when i use loud speaker. it worked very well, but when i play with my earphone plugged in.. driver status said processing : no
can you guys help me please?? thanks.. pardon my english

@unsavorypinkie
I also face this problem once in a while. Try toggling Legacy Mode on and off. You can also force close the app playing audio and Viper and then first open Viper, then your music app and resume playback. It should start processing again.

Then perhaps it could be due to the audio_effects.xml file. The file found in /data/adb/modules/ViPER4AndroidFX/system/vendor/etc has to be copied over to /vendor/etc and /vendor/etc/audio/inside whatever folder you have there. For me on a 11 Lite NE 5G it is SKU_YUPIK.
The file in the original location (/data/adb/modules/ViPER4AndroidFX/system/vendor/etc) must have v4a_fx mentioned in it. You can search within the file for it to confirm. It is after the copyright section.
After all this is done, restart and you should be good. Also ensure Legacy Mode is enabled and Compatibility Mode is disabled. If all else fails, try starting from scratch using the instructions by user "zgfg" that I linked to.
If it still doesn't work, then I'm sorry, I really don't know. Hope you can get it running though. The difference Viper makes is really like night and day!

that folder you mentioned is empty, and i've tried to search with my root explorer. unfortunately i don't have audio_effects.xml file on my phone.. how can i solve this sir?? can i download it from the internet??
EDIT : i have found it sir.. i have copied that file from data/adb/modules/VIPER4AndroidFX/system/vendor/edc to vendor/etc but i don't have folder named audio inside but i have folder called dolby

Sorry, I have no idea then. What I do know is Viper will not work with existing audio mods so you'll have to remove/disable those. There is a Magisk module for multiple audio mods, but I have never used it.
That yupik folder is specific to a 11 Lite NE. I have two other phones, they don't have a yupik folder in them. But they are also running Android 11, which is easier to get Viper working on compared to Android 12.
You'll have to research how to get it working specifically for your phone.

Question Anyone get viper4android worked on A13 (Pixel 6 series)?

I followed these steps (https://forum.xda-developers.com/t/...how-to-root-magisk-only.4382059/post-86183993) and it works on A12, but after the same steps on A13, the V4A cannot install the driver and didn't work. Does anyone successfully install the V4A? Thanks in advance!
Update:
Can anyone help @mustang_ssc with the required files (https://forum.xda-developers.com/t/anyone-get-viper4android-worked-on-a13.4480467/post-87518703)
Just to be clear, I know V4A works on many phones on the A13, but we're actually talking about the Pixel 6 (or 7) series, and no matter what magisk mods we've tried, it keeps asking for driver install.
Happy new year with the V4A reborn!

It seems to be broken at this point, I've run into the same issue; when opening V4A on A13 it wants to install the driver (+ reboot), but after that's done the app still won't work.
Would be awesome to know if someone could share a workaround, or we can together work on one.

Same here. I switched to JamesDSP Audio Manager v4.6 and really like it so far.
When installing the module, don't forget to select "Yes" when asked if this is a Huawei device. Otherwise, the DSP manager will crash.

@xpdragon I'm using Viper for the function "ViPER Bass" to boost some of the bass frequencies to my Sub. Does JamesDSP have something similar that works (most EQ apps didn't work well)?

Does JamesDSP automatically change your audio settings when you switch audio devices like V4A does? Like when you switch from bluetooth earbuds to your car speakers, on V4A it will auto switch the EQ, viper bass, viper clarity etc. to whatever you last set it as when using that specific audio device.

So for anyone else wondering, I went ahead and took the dive. Updated to A13 and tried out JamesDSP. It kind of(??) automatically changes your settings based on what your audio output is. It will switch between a speaker, headset(plugged in) and bluetooth profile. You can save different overall profiles (meaning it will save one speaker, headset and bluetooth profile) and load them but the problem for me is that it does not do it automatically. You have to manually load the overall profile yourself. This is unlike V4A, where it would switch the audio settings automatically when your audio output source changes. (This is actually how V4A used to be a while ago but now it auto switches)
Anyways, hope a fix for V4A comes out soon lol.

It didn't work, V4A keeps ask for driver to be installed.

@xpdragon Just tried JamesDSP, it's bass boost is "Enable Dynamic Bass Boost" and how many db, not really an equiv to the function in Viper4Android, I'll pass on this app.
At this point I'm on A13 waiting for a fix to V4A or a good replacement.

At this point I'm on A13 waiting for a fix to V4A or a good replacement.

James dsp it's just crashing on my p6p with a13

@sas46 I made sure to remove all Audio Magisk Modules (I had V4A, Audio Mod Library and Compatibility), uninstall V4A App then reboot, then install JamesDSP. I went far enough to confirm that the singular function I was looking for wasn't there and went straight to uninstall.

When installing, did you reply YES when it asked you if you have a Huawei device? If not, re-install and do so.

JamesDSP doesn't work with Android Auto like V4A but does just enough to get by.

Since we're on the subject, I'm curious if you guys have got any favorite profiles/presets you like to use with P6P.

Still nobody got it working?

Question V4A on OOS13

Hello,
has anyone managed to get V4A working on OOS13? If so, how?
Thanks for the answers, I won't be updating until someone confirms V4A works.

ViperFX for OxygenOS12/ColorOS12
1. Install AML and ViperFX 2. Reboot. 3. Launch Viper and install the driver. 4. Without running Viper: - From the archive AML.rar replace post-fs-data.sh along the path /data/adb/modules/AML - From the archive Viper.rar replace post-fs-data.sh...

Followed this and it works fine, but sadly Dolby doesn't work anymore

Hi I know its an old thread but, which phone did you use. I tried on OP8 Pro and it didn't work.
Edit: nvm. I didn't realize which phone forum I was on.

JamesDSP has a working version for OOS13. Unfortunately V4A is not yet good.
But JamesDSP is probably even better, because it supports lossless format.

Got an OP 9RT on same hardware and make V4A works.

Maybe you should install BusyBox from Magisk repository first.
Install AML & V4A modules
Install V4A app (do not run it!!!)
Reboot
Run the app
Use "Legasy mode" in settings
Start any music
Go to Viper and turn it on/off/on
It may couse bootloop. Use it on your own risk!
Dolby works fine too.

Thank you!!! Works perfectly!
Did kill my Dolby however but I'm really just happy to have V4A again. A couple times it did stop working but clearing the app's data and opening it again works fine, no reboot needed.

Works! Thanks.
"Playback Gain Control" and some other controls are grayed out. Are you getting that too?

Viper4android is popularly considered to be the all time greatest android audio mod. Imagine an equalizer on steroids that requires ROOT and custom driver. Honestly other than a couple kernel tweaks here n there V4A is my only reason to root nowadays...
