[Q] Viper4android : No effect

Hi,
I am using DN3 V5.5,.. I installed V4a couple of days back as per the proceduce given here on XDA :
1) Install apk version4 (for os above 4.x)
2) Open app, Install driver (I chose Super audio quality)
3) Enabled and rebooted.
4) Chose V4aFX in Music effects
5) Rebooted again
Did I do something wrong.. I tried various IRS files as well but there is no effect that I can really feel..
Can someone please help me on this.. I know there are lot of experts out there
thx

You did nothing wrong and this is unusual, have you tried dolby pro ligicII music irs? That irs is notificable and enable reverberation options like dry signal 50%, wet 10%, large room size etc. You should feel the difference.

I've installed V4A in the past because it was recommended but I couldn't really tell a difference.

It can't be mate, there must be something wrong, btw, viper doesn't boost sound, it modifies sound. If the installed version is correct and if you modify sound settings with different irs files, you must feel the changes. If nothing works for you guys, install 'Busybox free' from playstore and then check again.

[HOW-TO] Viper4Android on Lollipop

Since another thread is getting hijacked it might be a good idea to start talking about Viper4Android in a separate place. This is just to share some info, not a Q&A for Viper4Android.
Viper4Android FX is like the “advanced” version of DSP Manager/Beats Audio by providing you with more advanced Surround/Bass/Clarity/Gain boost controls in addition to an equalizer that you can use for your headphones, speakers, bluetooth devices, and more.
I found the guide on how to do it here, I just updated the links and added some more info:
1. You need root and twrp
1a. Make a backup in twrp
1b. Seriously, make the backup
Skip 2. and go to 3. if you are using SuperSU
2. Change to permissive mode with SELinux Mode Changer that you can download here
3. Boot into twrp and flash Viper4Android, you can download the zip from here (old link here).
3b. Reflash SuperSu
3c. Wipe cache and dalvik
4. Boot
5. Start Viper4Android and give root access
6. Still in Viper4Android, under settings switch FX Compatible mode to Compatible.
7. Reboot
8. Activate Viper4Android
9. Enjoy
Additional info:
If you use Poweramp, disable Direct volume control in settings/audio/advanced tweaks.
Do it at your own risk and for technical questions about Viper4Android it's better if you post in the thread you find at 3.
Some people report it working without changing to permissive mode, others report that it's not working at all. Any feedback is appreciated.

I've flashed it, tbh I only notice a small difference when activating it but I still have to play around with the settings. Also, I'm using Jetaudio, maybe it doesn't work that well with that.
Also, I've just changed the description in the op, according to the viper4android post I link to if you already use supersu (which is the same as in the rooting guide) you don't need to do the change to permissive mode.

Just curious, do you see a significant difference with your current v4a settings as compared to stock?

@charliebigpot you can add in OP that in order to make poweramp work with it, disable Direct volume control in settings/audio/advanced tweaks.

For me personally, I used lolliviper in the nexus 5 forums. Flashed through TWRP and then followed by SuperSU.
No need to change the selinux.

With the phone speakers, not much I played around with some settings to give sound a "fuller" effect.
However with Bluetooth or wired headset, definitely noticeable.

Do you guys flash busybox also prior to all of this?

Through the play store.

Edit: I'm sorry I miss read the post. Yes, install busybox first then flashing V4A through TWRP.

imo, poweramp's equalizer does an amazing job already. Just ramp up the headphone gain from mixer_path.xml and you're good to go.

Could you explain how you got it working? I've tried everything man. Normal mode /compatible mode. Tried all 3 drivers. Tried both selinux modes. Even tried changing the build prop with no luck. Any ideas or tips? I am on 2.1.3x myself. Rooted with supersu

First off i'll share my setup:
Recovery: Eng.stk Twrp r5
Kernel: Also by Eng.stk r61
Rom Stock 2.1.3-x
Viper4android: Use lolliviper zip from this thread: http://forum.xda-developers.com/google-nexus-5/themes-apps/discussion-viper4android-t2543796
I just flashed the lolliviper zip file through twrp. flash SuperSU 2.52 again just in case. wipe cache and dalvik. reboot.
after reboot, launch V4A app. grant supersu permission. install "high quality" (the middle one) driver. reboot.
Test by playing music (from storage, pandora, spotify etc.) keep music playing and then launch V4A again. go to 3 dot menu and choose driver status and it should show if its processing or not.
good luck.

I'll add the optional supersu step, but the rest is already there. After that it's up to each one to select between the 3 profiles at first boot.

Someone should try LolliViPER[6.0.1].zip zip on any 6.0+ ROM wit "Enforcing" kernel, see if it works.
I found this on the Nexus 5 post that is linked in the OP, guys got a bunch of Thanks for this, guess it wont hurt to try.

I'm also a beginner but I think you basically have to say which directory each file goes, look at your original mod and see the directories, use those.

[mod] [dual audio] [tulip] use earpiece speaker as audio

INTRODUCING DUAL AUDIO MOD FOR TULIP (REDMI NOTE 6 PRO)
What does it do(currently)?
This mod actually enables the earpiece speaker also along with the bottom-firing speakers. So you have a dual speaker config like the HTC10 has where the purpose of the speakers are same. The loudspeaker is untouched but the earpiece behaves like a mid-range booster and adds some more detail for the speaker audio output.
This mod will works on Any Rom (Stock and Custom) {Root Required}
Installation
1. Download " mixer_paths.xml " file from attachments below.
2. Move above downloaded file to " vendor > etc "
3. Rename the exists file to mixer_paths.bk so you can turn this MOD off when required.
NOTE: USE THIS MOD AT YOUR OWN RISK, USING THIS MOD AT HIGHER VOLUME LEVELS MAY DAMAGE YOUR EARPIECE SPEAKER.
Enjoy!

Neat, but do we need to move the file with TWRP? I've been trying to do it with FX, but it won't allow me to modify the file because I guess Magisk is controlling /vendor.

Try to move it using Root explorer pro or solid file explorer. Don't forget to backup original file first.

Well, I tried with a terminal, but for whatever reason the partition won't mount as RW. It persists as RO, which I imagine is Magisk's fault like I said. I'm gonna try with TWRP and report back.

I use it, but lost sounds on my Redmi Note 6 pro, I had to perform a rollback to the previous Backup.

It enables your earpiece speaker as a secondary speaker, makes music and videos much more enjoyable.
No you can't find it in magisk manager downloads, just download the zip, and flash it under the modules section.

I have taken a look at this module. If my understanding is correct, it tries to replace the default mixer_paths_tavil.xml with another xml file with the modifications that, I guess, should enable the dual speaker feature
I have checked that the reason why it does not work for me, is that after installing the module by means of Magisk Manager and the reboot, the mixer_paths_tavil.xml file is still the original. It has not been replaced by the one contained in the module
However, the path is well defined inside the module (mixer_paths_tavil.xml is contained in folder system/vendor/etc)
Actually, I'm experiencing a similar problem trying to modify directly the mixer_paths_tavil.xml, as described here https://forum.xda-developers.com/lg-g7-thinq/themes/changes-to-mixerpathstavil-xml-lost-t4035345
This is happening to me on Pie
So I wanted to ask you, which Android version are you running that it works for you? are you on Pie?
Thanks

Works for me on Oreo, along with Ainur Sauron, Audio modification library, Audio compatibility patch, Viper 2.7.1. Also, there's a working Dolby Atmos downloadable through Aptoide.... doesn't even need root, just a quick apk install. Make sure you're covering the bottom speaker completely and put your ear to the top speaker. It's not going to be mind blowing regarding volume. It's likely because there's no way to turn the values high enough to complete with the bottom speaker without doing damage.
