AdAway and V4A

I know root is brand spanking new to our lovely phone, but I was wondering if anyone has tried AdAway or V4A?

I rooted using the method in the Snoke Kernel thread. Then I installed AdAway and the ViPER4Android Magisk module. Both are working flawlessly for me.

Thank you, now I'm even more excited to get off work.

Oh yes. Installed V4A yesterday and tuned sound for my preferences. Boy it comes close to the HTC One M8 in terms of loudness and clarity.

Did you install V4A via Magisk, or an actual zip? I installed via Magisk and it doesn't sound different.

Magisk. You should reboot after first start of the app. Two times in total after enabling the zip in magisk

FX for Magisk 14+
Sendt fra min Pixel 2 med Tapatalk

Hey guys. Sorry for asking for help. I read up on Magisk and V4a (haven't used v4a in years), didn't use on my OG Pixel. On my Pixel 2, I have magisk installed correctly. I tried to install the Magisk 14+ but getting the driver i/o error. I installed the SE Linux permissive script in Magisk but it didn't do anything.
Am I missing something simple or something more complicated? If you can direct me if it's easier, I can read up on it.
Thanks!

Did you use the Viper4Android FX for Magisk 14+ module?
---------- Post added at 05:05 PM ---------- Previous post was at 05:04 PM ----------
Viper4Android seems to work fine for the phone speakers. But with bluetooth mine doesn't process whatever I play/stream.
Could you guys test if I'm the only one that have this issue?

Hey yeah I did. I'm on 8.1 preview if that matters.

It does. In the kernel/root thread it is stated, that the guide is only for 8.0. I had to flash 8.0 again to revert and enable root, Magisk and V4A

Tried to test it out since 8.1 with magisk root worked hah. Wanted to experiment with magisk some more. Thanks again for your help!

Installed this on my pixel 2 and I'm getting driver status abnormal along with not processing. I have not tried it over bt yet though.

Got it working for the phone speakers with the SELinux switcher. Has to be in Permissive. I'll check bt in a bit.
So far BT is not working.

Ok Guys need some help. . .Installed Snoke.R9se and magisk v14.4. Loaded Viper4Android Magisk 14+ and enable. Driver status says enabled but not processing when music is playing with Poweramp, Neutron, and also Google Play Music. Direct volume control is NOT enabled in Poweramp. However, I have sound set for touches and Viper is processing those. ot sure why its processing system sounds and not music. Oreo 8.0.0 Pixel 2.

So I flashed the November update, installed Snoke.R11.zip, magisk. Did the phone setup, then installed BusyBox and V4A via magisk. Drivers are enabled and it's processing on Pandora, and Pi music player.

I've tried to install this several times and the driver never gets enabled. It asks to reboot in order to install the driver every time I open the app after rebooting the phone. Did you do anything special? What's the secret?

You have to choose viper4android fx.

Thank you all for your replies. Zack helped me figure out the issue. I had installed Audio-Modification-Library module which was preventing A4A installation. Cheers!

Because of this post, I decided to install the Audio Modification Library module to see what it does. Oddly enough, for me, V4A actually started working after enabling this additional module and setting my kernel to permissive. Weird. Glad it's working now though!

lol... nice!

I just had the same issue as a result of upgrading stock MIUI Android 7.1 ROMS on a Xiaomi Mi Max 2.
I solved it by:
1. In Magisk, disabled both Audio Mod Library and Viper4Android --> REBOOTed.
2. In Magisk, ENABLED both Audio Mod Library and Viper4Android. --> REBOOTed.
No driver errors and it works in Speaker and Headphone.
But I'm not getting any Viper Notification in the Shade or the Status.

Did you try Disabling/Enabling the modules in Magisk? I had to do this a few times before it worked. Viper status will report 'Processing: No' until you start playing a music file, then it should change to 'Processing:Yes'.
I was able to get the notification to show up by selecting the first option in Settings>Show Notification.

I've tried just about everything I can think of.

Here's what I don't get. I have 3 devices currently. All running Oreo. Huawei Mate SE, Xiaomi Redmi Note 3 and Ulefone T1. The Redmi Note 3 and Ulefone T1 both have V4A working fine and both kernels are Enforcing. The Huawei no matter how it's set refuses to work.

[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.

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'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:

Select NO to the second option and then use Vol - (remove Volume Listener Library). This is done so that your audio won't crackle.

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:

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.

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.

Anyone got Viper working? I've installed the material one from here, audio compatibility patch etc but it doesn't seem to do anything?
I loaded some profiles into the folders and the app also crashes when I try and load one

About to test that right now.
Use the one in Magisk called Viper4Android FX not the legacy.
This one works for me.

Have been using it since day 1 after installing Magisk. Has been working, the same as the 6T.

yes here is a magisk module of VIPER4Android 2.7.1.0 magisk module i made based on APK so no other special things needed.
Just open app and it will ask for root and install drivers... will auto reboot and done...

Hi,
Thank you for the module you have created. I am attempting to use this on my op7p, but it does not appear to enable. I am rooted and used magisk to install the zip, then rebooted, then ran the program to install the driver. The profiles folder for viper is loaded to the root directory. Running audio on my Bluetooth headphones defaults to Dolby Atmos "balanced" mode, which I cannot disable without toggling audio sources. It seems to default into thinking they are wired speakers until I toggle between speakers and Bluetooth. After this, I can disable Atmos processing, but still no luck enabling viper. Additionally, attempting to enable the higher quality codecs in Dev options never takes, they seem to revert to system default as soon as I exit the menu.
Running viper shows "driver enabled: no", and "processing: no". Did I mess up a step of the installation, or is something missing from magisk/viper?

try to go to settings > Attach Audio effects and enable and then disable (while music is playing to see if you can tell a difference)

Hi, thank you for the quick reply. Toggling audio effects doesn't appear to have any audible differences, but if it is on, the status goes to "abnormal" and the audio format is unsupported.
Toggling master limiter enables/disabled driver status, and apparently my music player (pulsar) is not supported or recognized by viper. Using YouTube vanced I am showing that viper is indeed processing, and I can tell what is working or not. Looks like it's time to find another media player :fingers-crossed:

Do I need to do anything to the inbuilt Dolby before installing the V4A mod?

Thank you

Yes mate, go into settings for V4A and enable effects and master limiter. Then change song and you should be good to go. Also, go into the V4A folder. Move all of the files in the DDC-Orig folder and create a new folder called DDC and move the files into there. Now you should be able to use the profiles

I had to install the magisk modual first and then install the apk version from xda labs before it would work.
It now works on Spotify but not on other apps like bandcamp.

I got it working on my oneplus 7 pro by following this video on YouTube.

Not here though.

Something is messed up in OxygenO and OnePlus won't care anyway, so it's what it is. I mean, the delayed notifications have been plaguing OOS since what? 3 years? So hey, maybe in 10 years they'll take a look at this. Until then.... just move to LineageOS or some other rom as an alternative.

If you have installed another sound mod, you need to install aml after installing viper. Otherwise, they conflict. That's all there is to it.
As for delayed notifications, the only thing that I can think of is that your messaging apps are not set to don't optimize in battery settings. If not, they will be set to sleep and you will only receive your notifications when you open the app.

Common sense guys , It has Dolby installed , so that's why it detects it . Just install Audio modification Library and Audio Compatibility Patch , solved.

So the thread is simple. I wanted to install Viper, to lower my media volume cause even 1 is too high. Now... I was able to install Viper easily on a Pixel 3a XL.
Just grabbed the Magisk module and off it went.
Not here though.
I get a message saying...

! Conflicting audio mod found!
! You will need to install !
! Audio Modification Library !
Attached the log and screen.
Tried everything since. The app from XDA Labs, the MOD lib it talks about. Nothing.
Maybe something left some junk somewhere? But how do I clean out all the Viper remaining parts?
Thanks for the help...

Try viper4android v2.7.1. Just install driver 2x ( will reboot 2x too) works great for me.

This is an issue with Android 10. This is how to fix it:
