Which Audio enhancement app for CM12.1 nightlies

Until now I've been using Viper 4 Android for audio enhancement, but it's not working as it used to with other roms. Now, I am searching fot a replacement. AudioFX is very poor compared to V4A and it does not seem to work either. For now I settle with Poweramp's equalizer and enhancements, but is there anything better that works? Thanks!

Have you tried changing the selinux status to permissive? That's what enables v4a to work.

Now that you mention it, I did not double check if it's set to permissive. When I first installed V4A I had set it, but maybe it was reset and maybe that's why V4A stopped working. Either way, V4A's equalizer never worked, not even when V4A seemed to be working correctly.

V4A works for me ever since CM 12. You just have to install it correctly. Also there is a flashable .zip in the official thread on page 1886, which enables running V4A with SELinux enforcing

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'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.

I managed to install viper on op7 OOS10.0.1 with bluspark kernel with the following method:
1) uninstall every AML and ACP and viper stuff and reboot.
2) install ViPER4ANDROID 2.7.1.0 apk from xda labs and open the app but dont install driver. put the app in background
3) go to magisk>downloads and install AML module. it will ask to reboot. dont do it.
4) go back to viper and install driver. it will automatically reboot.
5) after reboot go to magisk manager and UNCHECK (NOT DELETE) AML and open viper and install driver again.
6) now your phone will boot with viper installed
Note: (if viper driver is installed but has no effect then go to viper and click on 3 dot menu then click on 'attach audio effects' once viper start working you can detach it). you can use App Systemizer on magisk repo to systemize viper app to priv-system app so that it doesnt get killed in background. you can also hide its always on notification. viper will always run in background. but i saw no battery drain difference. Enjoy

Worked for me in Stock Rom oos 10.0.1?

Or you can easily flash in magisk repo

Good alternative module repo magisk James DSP (DCC and irs files supported)

How are you guys rooted on oos 10?
I lost root when I updated and when I went to redo it I found that the process changed for Android 10.

I installed it the complicated way, thats written up there and it worked fine. I had to wait because i lost root in the oos 10 update, because i flashed magisk in the wrong way. And there was no twrp that worked for me, fastboot boot didnt worked at all, so i flashed magisk to the boot image and i got root again with viper4android and everything works fine.

Question Anyone get ViperFX functional on their OP9?

received Buds Z for my OP9 purchase and have very slowly converting to the new phone (rooting, stability and assure privacy issues were addressed) and was very happy with their performance with my rooted OP6 on A11-Pixen OS with ViperFX. Without VIper, the sound is lackluster. even a downloadable EQ makes minimal difference.
Attempting to convert fully to OP9 today and installed viperFX mod form magisk but when I attempt to perform the initial launch to download and install the driver, the phone just reboots without actually getting the driver installed. Im not sure if its a hardware compatibility issue or the fact the OP9 root isnt as full and fleshed out like the one on my OP6. (something about DM verify and/or selinux enforcement? idk, I am pretty lame at the deep understanding of android 11s workings)
I know there are a few other magisk mod for audio listed and more that i could possibly find that arent and add myself via zip installation but even if one ends up working, I will still be aiming for VIperFX as my preferred solution.
If anyone has a solution, plz reply (or whatever possible replacement you've chosen)
PS. I swore the buds z touch controls were suppose to be customizable. anyone else unable to set custom controls for them?

In magisk, install "audio modification library". That should fix the driver issue.
To customize the touch controls, go in Settings, bluetooth and device connections, bluetooth, settings cog next to the buds, headphones. Now you can customize them. Not a lot of options though.
You might need to install the oneplus buds app first.

Same issue. Tried ACP as well, just gave up on it and using the inferior built-in Atmos

No, but I did install James DSP and it's working just fine.

@applyscience
After alot of trail and error I finally got ViperFX working on my OP9 !
You must install magisk-permissive-script_v1.2 and audio modification library modules in Magisk and of course the ViperFX

Glad you got it working! I wonder why I didn't need to do that
Hopefully it works for everyone else.

Just use JamesDSP. Same functionality as Viper, and works 100% of the time.

Okay it randomly worked for me after installing the BusyBox magisk module, then the Audio compatibility module, then the Audio modification module and then viper. After that the driver installed but did not work. After setting the selinux mode to permissive and switching to legacy mode in viper it worked flawlessly.

Im trying for several hours now, i have tried everthing i found including this Thread
(https://forum.xda-developers.com/t/app-fix-100-working-viper4android-for-android-11-devices.4213647/)
Nothing worked for me anyone any idea, i have allready updatet to the latest OxygenOs (11.2.4.4.LE25BA) Maybe thats why it doesnt work?
