Dirty Unicorns can't install V4A drivers

Hey guys. I'm trying to get viper4android working on my Nexus 5x running the most recent stable version of Dirty Unicorns.
I tried just normally installing the apk. Changing selinux to permissive. I have the newest version of su and BusyBox installed and yet the driver refuses to install. Every time I restart my phone it says I need to install the driver.
I've been looking around online and I can't seem to find a good answer for what exactly I need to do to get it working.
The popular thread in the Nexus 6 section has way to much info and I just can't follow it to install it properly. I basically want viper4android so I can use pulse with Spotify.
Any help would be appreciated. Thank you!

Flash either of these ViperAudio or ViperAtmos (if you want Dolby Atmos too) in TWRP. It works even with systemless root and enforcing SELinux.

Installing V4A or other audio mods

Hello everybody. I have Magisk and couldn't install Viper module, neither the usual viper .zip via TWRP.
Have you been able to install any of the available audio mods on your Z2 Play?

I too am interested.
I prefer the Atmos version, ViPERAtmos 4.8 Sony Beats Universal Edition, but I don't think it's compatible with Nougat.
Any advice would be greatly appreciated!

I installed ARiSE sound system in my z2 play, which contains Viper and Dolby Atmos

I have a module called viper 4arise installed and its working very well

Could you post a link to the download / thread that worked for you? I can try to install and make a simple tutorial for other folks.
Thanks!

Here https://forum.xda-developers.com/android/software/r-s-e-sound-systems-auditory-research-t3379709 install the last stable version

Thanks! I've looked at ARISE a few times, but it seems life meant steps to install. I guess I'm going to have to bear it.
Does it sound as good at Atmos?

I manage to install it. It's overall pretty simple. You can extract the installation .prop file to /emulated/0 and edit it there to get a 1 cycle install. Otherwise your first try will do just that and return an error (so you'll have to edit the file anyways).
I tried all versions of viper there but none worked (all showed abnormal status) also, remember to mark for installation the Magisk compatibility.
I'm using Atmos, working very nicely, but still wish Viper had worked...

That's weird, I have Viper and atmos working in my device. Previously I set SElinux permissive and installed Busybox

Oh that must be it. I have it on enforcing. Will test with permissive then. Thanks!

Well, it worked! AriSE with SELinux mode changer set to permissive.
Thanks a lot!
With Dolby and viper our speakers sound WAY better! Headphones are even more awesome!

Sound Mod | Viper4Android | Magisk 16 |Oreo | 25.04.2018

Hi guys,
I just tested several Sound Mods for Android. So I want to share my best settings for the HTC U11 + U sonic Earphones with you.
Working on:
Stock based ROM (8.0 based)
LOS based ROM (8.1 based)
Install Viper4Android via MagiskManager (Get it from here or directly under Downloads in Magisk, I am using Viper4Android 2.6.0.4 with the new Material Design)
Reboot
Install the AINUR Audio Mod (Get it from here or install it directly through Magisk Manager -> Downloads -> Ainur Sauron.)
Reboot
Install AML(Audio Modification Library) via Magisk or flash it from here
Reboot
Open Viper4Android. Driver Status should be working now. If not dirty Flash your ROM and start again at 1.
Load my HTC U11 Profile that I attached to this post. When using Viper4Android FX greater or equal to version 1.6 than use the v2 Profile. Everything lower than Viper4Android FX 1.6 just use the v1 Profile. Unzip the attached File to the Viper4Android Folder at the Internal Storage of your Device. Dont forget to load the Profile in V4A.
Hope you are enjoing this as much as I do. If you got any recommendations or suggestions let me know.

for me is processing on no, have already made as described a dirty flash of my Rom
edit: I have solved the problem with the music player just pause and play again and it works

Did you already installed another soundmod? This happened to me after I flashed ARISE. Only a full wipe helped me out. I am also using Leedroid R124.

I uninstall sauron and aml befor i try to flash all the stuff in the way you describe it. Before i have sauron only.
After i uninstall dolby in twrp the phone boots up normaly.

Hmm maybe its a problem with sauron that Dolby dont work when you flash sauron before. As I said I recommend a complete wipe then it should work without any problems.

I saw in Leedroid thread that you have to change a line in arise_parameters1.prop , to avoid bootloops

After flashed as your instructions, everything works like a charm bur only ANC not work anymore

I finally got it to work, but sound quality is not as good as on Dolby Atmos Nougat, I think I will stick to V4A + usb dongle boost mod till dolby is updated

Will just the viper4Android work and give good sound quality
Sent from my 2PZC5 using XDA Free mobile app

Actual Dolby can't work while V4A works, at least with me, I have to disable one of them so the other work, but anyway actual dolby on oreo is not good as audio quality, it was way better on Nougat

I have yet to get Ahrion's version of Viper4Android FX to work. Even his AM3D Zirene Sound hasn't worked for the 11 since Magisk. The only one that works for me is ShadySquirrel's for Magisk v15.

I can use Ahrion's version, but it has to be the v1.5.2/2.5.0.5 version. I've never been able to get any 2.3.4.0 versions to work on Oreo, due to the driver not being able to install.

Anybody get Dolby to install? I'm getting Api error

I must reckon the new Dolby port on Oreo is pretty good, I am using dynamic selection to boost both surround and bass. Always be sure to have Dolby surround mode On (green icon)

Can anyone get the profile to work on updated viper on Magisk. I can see it in my profiles but can't get it to take

[SOUND][8.X][D6603][Z3][CARBON ROM] Dolby Digital Plus AND Viper4FX for OREO

Just want to sharing some alternative to making our D6603 sounds boom... and seems can implement to other phone because all of components that i have installed are universal (wish work on all phone other than D6603), just try it but don't blame me
After fighting about 2 weeks to getting DOLBY (effect) including VIPER4 in my D6603 with latest CARBON Rom, finally i found an alternative for that.
Because when i try to install Dolby Atmos (standard/unity) always "unsuccessful", installed but no app in drawer that made me headache
My phone configuration :
- Magisk 17.1 + init.d injector
- SELinux permissive.
- AML and ACP installed. Get in here (for supersu seems AML modul not necessary because the installer will search magisk directory, so you just need ACP modul)
- Viper4 FX from here
- DOLBY DIGITAL PLUS for 8.x (i found in somewhere at XDA, thanks already make it work on OREO :good: really appreciate it)
Step: i am installing all components below via TWRP (you can try with your own way)
1. DDP.
2. VIPER4FX. (to escape from Viper4 FX asking the driver installing repeatedly, please install it after DDP or other sound mod.)
3. ACP (additional).
4. AML (essential), better doing at last because will detect and patching audio module on DDP and VIPER4 for compatibility.
On each step i do reboot then back again to TWRP (only want to making sure the components already installed).
When all done let try boot to system and open Viper4 (check the driver is installed or no), next playing the music, the lasting is open DDP to getting more bass. ENJOYING your music.
Noted: for compatibility reason i remove musicfx/audiofx from system. please do backup first.
Results :
- Phone speaker, WORK.
- Headset, WORK.
- Bluetooth speaker, WORK.
- Jack 3.5, WORK.
Playing music via Spotify and internal player all work.
If it work on different Phone than OP, please report back. Would be appreciate it.
Thanks to
- @Myself5 for Carbon Rom
- @guitardedhero @worstenbrood for DOLBY DIGITAL PLUS 8.x
- @nailyk for the TWRP
- @ahrion @Zackptg5 for Viper4 FX AML ACP
- @topjohnwu for Magisk
- @matt1313 that already provide DDP installer for 8.x

Work like a charm
Thank you

Yes, you can.

Simply flashing the package right? No need of anything else

Correct. Just flashing all packages, and i suggest you to install Viper4 at the end (if you prefer)

DDP need permissive mode, will set by dolby.sh in init.d
If your rom doesn't have init.d but you use Magisk, just copy dolby.sh to /sbin/.core/img/.core/ service.d or post-fs-data.d
Viper4 can work on enforcing mode.

Why not try it and report back
For supersu i think you just need DDP, ACP, VIPER4 and making sure your init.d and permissive are work.
Those modules can install on Magisk or System.

your init.d work, right? Because i just try installed DDP only on 5.x firmware with supersu and work :good:. How about /system/su.d any issue or no?
In my opinion, this DPP actually can running on 5.x-8.x firmware with supersu/magisk. See this video to confirm on 5.x ...sorry, no idea probably the issue came from stock rom.

DDP doesn't work on all 8.x firmware & works on older android, it might work for you but not everyone, thus it was said in Arise thread that DDP won't work on all 8.x, init.d & su.d works here.

Im using redmi 4x with latest aex oreo rom
- works on speaker
- DDP crashes sometimes
- when using headset both DDP and Viper doesnt works on spotify and music player, but in youtube or other video player it works well.
Maybe you can help me fixing this problems, thanks

Blocked option to switch selinux enforced to permissive on custom android 10 roms.

I have had Redmi Note 8 Ginkgo since December. From then on, I am waiting patiently for the appearance of refined custom roms. Recently, roms have finally appeared where all camera lenses work! But I miss one thing very much... Since I had the RN4x I have been using the Dolby Plus mod. In the RN8 it clearly improves the sound, has more bass and is louder. I mean the sound on the built-in speaker, not on the headphones. Dolby Plus can handle bass better on the built-in speaker than the Viper4Android.
This mod however requires SeLinux to be permissive. All android 10 roms that I tried have a SeLinux Enforced kernel - for some reason switching between enforce and permissive is blocked. Even some roms do not allow flash another kernel.
How do I unlock the ability to switch Selinux enforced to perrmisive when the magisk SELinux Manager module is not working?

Please read the last sentence of my post. I used two ways to change selinux, they work on miui, on
other custom android pie roms. Is this module from you unique?

I did read your entire post. I was just offering an alternative, so whether or not you want to give it a shot, is upto you. If it works for you, great. If it doesn't, get in touch with your ROM developer. Over, and out. :good:

SELinux
There's an app called SELinux mod changer, try that. I used that to change permission to permissive on my ginkgo(Android 10) and it works perfectly.

Respect man, this magisk module works!
The few modules that I was using apparently did not work properly with android 10. I thought the kernel was blocked in some way, and this is a matter of choosing the latest selinux switcher.
Here is the link to the source where this magsik SELinux Switch module comes from:
https://github.com/nipunnarang/selinux-switch
Do you know how with some magisk module or buildprop modification to:
- set the back button to close / kill the application
- the appearance of recent applications was like in android oreo?
I found scripts for it once, modules and now I can't. I prefer not to install xposed

Good to know it works. I made it. The link you've provided is my GitHub. Also, no, I don't know if there's a Magisk module for those two things. For the former, you can try using Button Mapper. It requires root, but not Xposed. And for old Oreo style recents, it needs a modification to the ROM, which can't be done via a simple Magisk module.
