[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

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.

Duuude. I don't know how. But it worked xD crazy how simple that was yet I couldn't get it right in so many tries. More ppl should see this. Maybe OP can even add the steps into OP. Thanks mate!

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.

uhhh this zip only contains a Ds.apk and a dolby config which is the stock file of M9's BoomSound presets :s am I missing something here?

why do you use/took xposed framework installer and just added some files into it, which even won't really flash properly..

It's an updated Ds.apk and its not a stock file its been modified which is to make the speakers more louder.

sorry to say, but it sounds weird on headphones and also speakers output is even worse then stock

New Update Changelog: 8/24/2016
Added HiFi Audio libs x64 and sound effects

Has anyone flashed it yet? ��

didn't tried yet, but since this needs sense rom, you need to edit the HTC_audio_effects.conf in /system/etc/ not the audio_effects. where did you take the libs from?
@ZeroInfinity please take a look

New updated made more fixes boomsound setting and presets works like a charm now. Backup if some settings are broken from your rom send your build.prop for a fix :good:

Have you even tried it yet?? Or are you hoping every 1else will
Æaa \../

it breaks audio on htc music player and kills boomsound on ICE10 port.
and why you put a complete build.prop inside the zip, instead of making a script which changes only th things it needs.

Viper4Android for s6 edge plus /note 5

I have the s6 edge+ and my wife has the note 5, can't get Viper to work just like everybody else. Other phone's versions of OS use mixer_paths.xml to adjust volume/levels, but these 2 phones have a separate file titled mixer_gains.xml where volume levels can easily be adjusted. Is this separate new file the reason why Viper won't work?

Here is a combo audio enhancer for all you audiophiles: https://www.androidfilehost.com/?fid=24562946973631338
This twrp flashable zip file contains not only viper, but this has the three finest audio enhancers in it which are fully
compatible to any android phone which has already been updated to the new Marshmallow 6.0 firmware.
This contains Dolby Atmos, Viper4android and Beats Audio all in one flash able zip file.
Also after you flash this it will only create one icon in the app drawer but when you open it it will give you a choice
of any of the three or you can even use all three at the same time if you like.
Good luck,
Have a great day.

Oops it was in the Dolby Atmos thread by westenbrood. My brain is derpy sometimes
HERE YA GO!
It's right there past the 6.5 download link, can't miss it. I don't know for certain if this is the magic answer for nougat, but if viper is showing all is well other than the driver status being abnormal (which was the problem with MM) then you should be good to go after flashing it. As always YMMV. Make a backup just in case.

I've tried everything to get viper to work, I don't understand - previously all I've had to do is install the apk, install drivers - reboot & jobs done!
Now it's like you need a masters degree.
I've followed so many guides, viper apk is installed, rooted, busybox & I've renamed the file in system / etc - but upon opening viper & attempting 2 install drivers, I'm told installation has failed.. something something busybox, something something check if rooted :what::banghead:
My hope now is a Dev will build a beta 9 build & incorporate viper
