Hi,if u like V4A audio efect.ill share how u can use V4A in AEX rom.
First,u must rooted and install busybox.
-Ok if u done upper step,lets boot your zuk z2 into twrp
flash v4a4.2.zip(V4A 4.2) and reboot system.
-Now launch V4A,install driver and reboot
Ok,now its time to update latest V4A version 2.5.0.5
-Install RootExplorer (optional) or u can use twrp file manager to delete V4A 4.2 apk in system.
-Flash V4A 2.5 in twrp and u done.
Optional you can delete apk in system or disable MusicFx.

thank you, but i didn't find or couldn't do the delete part with root explorer or twrp, but it worked anyhow.

If you using root explorer try find viper4android 4.2 folder in root/system/priv-app.

Thank you for your information. I have got much easier way to use it(if you have magisk installed). First install the viper4android zip using twrp. Reboot. Then open mgix go to download and select viper4android. Just tap on the arrow and tap on install. After installing it will ask your permission to reboot. Just reboot your device and enjoy. Sounds tricky but process is as simple as water.

I flashed ARISE and it worked normally. But as for sound quality...meh

I don't think sound quality would still be lacking after you installed ARISE. Do share your setup (pm me, this isn't the correct thread) so we could get to the bottom of your issue.
Sorry for OT!

If the hardware is ****e any kind of software is not going to make it good. It's not magic.

does it work on aex 5.1 ,( the january update)?

Haha, very timely post. I was trying to get Viper for the first time on Oreo two days ago.
One question, are apps other than music players processed by Viper as well? I ask because I installed Arise but emulators and games didn't get audio processing, only my music players.
Thanks!

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)

[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

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

How to increase music volume?

Hi,
I'm currently on MIUI 12.6 by xiaomi.eu and somehow I can't increse the volume on the phone while listening via bluetooth in ear headphones.
It says its on maximum, but in comparison to my old Redmi 4x the volume is at about 75% feeling...
Does anyone know a hidden setting to increase the volume?

Thanks for the hint! I installed it and it got a bit louder, but still not loud as with my Redmi 4x..
It's so strange.. could it be because of the ROM? On the Redmi4x I use the resurrection remix rom. On the gaugin I use MIUI 12.6 by xiaomi.eu

Also I need to add, that I cant find the option to toggle Absolute Bluetooth Volume in Developer Options...

You can adjust the gain in the settings to make it louder etc

Yeah, I did this (see screenshots) but no improvement here I also shared two screenshots from the developer settings section, to prove that there's no option to toggle Absolute Bluetooth Volume

You can try directly editing the mixer_paths.xml yourself
Use a file browser browser with root access
Find vendor/etc/mixer_paths.xml
You will need to research yourself what values needs changing to increase volume
I have included the stock mixer_paths.xml below - you could try simply replacing your one with the stock one however it may cause a bootloop. Make sure you backup your existing file first. Set file permissions to 6-4-4 or rw-r-r
If it bootloops just replace original file via twrp or restore your twrp backup

Question Atmos support with Magisk

Hello,
Has anyone here been able to use some Magisk module or any other way to enable Dolby Atmos on these phones? I've tried 3 or so different Atmos Magisk modules now and every one of them froze the phone on either the Google logo or on the boot animation (and I had to manually reflash, remove the module files and reinstall Magisk).
The three I've tried already:
some random one from the forums (author hellboy017, for 1+ 8 series) - I don't remember where I got it from anymore
Dolby Atmos Magic Revision
Dolby Atmos Razer Phone 2
None of these worked. By the way I'm not running stock but Evolution X instead - latest build of it. I don't think it matters but I mentioned just in case it does.
I'd like to get Atmos working because I got a 3mo trial of Apple Music which supports Atmos but not on Pixels. My $300 Samsung supports it...

I can't help with Dolby Atmos but you can use viper4android re

Using Magisk Delta? I tried installing it multiple ways - direct install, recovery sideload, patching boot image with and without uninstalling normal Magisk before, but I get the same issue - the EvoX boot animation stops after a few seconds, then it resumes after a few seconds and this goes on without booting... Tried ADB to get some insight but windows says that the device couldn't be recognized.
