Work well, no problems here. Thank you !!

Loving your work man! Will you still be updating this zip? It's really rocking my N6 but I don't see it in the OP so I was wondering if it was just a one time build.
[Nexus 6 Themes and Apps] TorinTPG:
I just came across this thread after trying to get V4A installed for hours yesterday (endless drivers prompt when launching). I followed the instructions for ViPER|Atmos™ 2.5 Audiophile™ Dark by guitardedhero.zip. It informed that I was successful, wiped, and rebooted. When I rebooted the phone, V4A is not installed in my app drawer. Do I need to manually install an APK or is something not working correctly?

Thanks for your assistance

Installation:

Boot to recovery

Wipe > Advanced > Dalvik Cache, Cache

Install > ViPER|Audio™ OR ViPER|Atmos™

Wipe > Advanced > Dalvik Cache, Cache

Reboot

Edit - formatting
[Nexus 6 Themes and Apps] guitardedhero:
Sounds like my zip did not delete a previous v4a install. If you have a copy of a compatible rom zip do this:

Delete any folder with viper in the name in /data/app

Boot to recovery

Wipe > Advanced > System, Dalvik Cache, Cache

Mount > uncheck System

Install > rom zip

Reboot

Check for sufficient free space in /system

Boot to recovery

Wipe > Advanced > Dalvik Cache, Cache

Install > ViPER zip

Wipe > Advanced > Dalvik Cache, Cache

Reboot
[Nexus 6 Themes and Apps] TorinTPG:
I'll check on this

Will I get an error when I flash if there is not sufficient space?

If the driver status says it's not processing, does that mean the effects are not working? I cannot force viper to request superuser permissions.

ViPER|Audio™ 2.6 Audiophile™ Dark 5x/6p Edition

ViPER|Audio™ Super Quality Driver for 5x/6p​

The two attachments below are for those with no /system/vendor/etc/audio_effects.conf but with /vendor/etc/audio_effects.conf to test for proper ViPER driver installation.

No need to install both, the driver install zip is for those with ViPER installed already experiencing persistent install driver prompt. ViPER|Audio™ 2.6 is for a new install on a clean /system.

Let me know the results, thanks guys!

I'm still using your 6.0 version on my Note 5.Is the sound for you better in 7.0?

Thanks.
[Nexus 6 Themes and Apps] luigidk:
I am still being prompted to install a driver when I run V4A. I have the feeling that the 2nd ZIP installs the driver so I shouldn't be prompted ?
[Nexus 6 Themes and Apps] guitardedhero:
Both zips are intended to install driver, the driver zip is to flash over an existing v4a install with persistent install driver prompt.
[Nexus 6 Themes and Apps] luigidk:
I've flashed the 2nd zip twice - still no driver.... anything I can look at?
[Nexus 6 Themes and Apps] TigerSoul925:
I've been out of town for a few days for the holidays so I haven't had time to try 2.4.1 yet. Judging from the above you've moved on toward finding the problem, but I've seen posts below that it doesn't yet work so I'm holding my horses until you get it figured out. Let me know if you need me to test anything. 6P here.
[Nexus 6 Themes and Apps] TigerSoul925:
As to where I am, on 2.4, not yet tried the 2.4.1 you gave me, what should I flash of the latest 6p zips?
[Nexus 6 Themes and Apps] luigidk:
I've run the 2nd zip twice - no driver. Is there anything I can take a look at ?
[Nexus 6 Themes and Apps] guitardedhero:
I really do not want to overwrite the audio_effects.conf files like most sound mods do but these two zips do just that. I'm curious if this is the only file I'm having trouble patching or if there is another file that has to be patched that I am unaware of. If either of these two zips don't fix the driver issue then there is another file that needs to be edited that the v4a app itself is not patching either.

I don't know if I wrote the script to extract /vendor outside of /system so if 2.6.1 doesn't do the trick then simply extract the vendor zip and copy audio_effects.conf into /vendor/etc to overwrite the existing one, set correct permissions, and reboot.
[Nexus 6 Themes and Apps] guitardedhero:
Look for /system/lib/soundfx/libv4a_fx_ics.so

Look for v4a entries in:

/system/etc/audio_effects.conf

&

/vendor/etc/audio_effects.conf

It very well could be the wrong driver for your device.

With a dirty rom flash over a wiped System in TWRP, extract the ViPER zip and copy MaterialDarkV4A folder into /system/priv-app on your device and set permissions for the added folder and the apk inside. Reboot phone and open v4a and install driver when prompted and reboot when prompted. Open v4a and see if driver is installed. If it is, I would really like to check out the following directories:

/system/lib

/system/etc

/vendor/etc

If you get v4a and its driver installed the old school way by just copying the folder, setting permissions, and rebooting then the info I need will be in those three directories.
[Nexus 6 Themes and Apps] luigidk:
Great - what are the proper permissions?
[Nexus 6 Themes and Apps] Golf c:
Nexus 6p. I have to delete the original audio_effects configs file in vendor/etc before the driver will stick. Works every time. Then I replace it with the one in system/etc. This has to be done with all viper installs I have done. My only problem is my notification sounds are viperized , no matter what I do. Works great otherwise. THANK YOU for all your work with music mods. Much appreciated!
[Nexus 6 Themes and Apps] luigidk:
I took Golf C's suggestion - deleted the audio_effects.conf from /vendor/etc, then copied the audio_effects.conf from /system/etc/ to /vendor/etc - set permissions "644" and V4A now is now working - sees the driver and is not prompting to install it.

Also - it is seeing the NEON driver - 2.3.4.0 - so is that the driver from the 2nd zip ??
[Nexus 6 Themes and Apps] guitardedhero:
What is the name and size of:

/system/lib/soundfx/libv4a_fx_XXX.so?

You can zip and attach the file if you want.

Thanks guys!
[Nexus 6 Themes and Apps] Golf c:
Here is the whole soundfx folder? Nexus 6P
[Nexus 6 Themes and Apps] luigidk:
View attachment libv4a_fx_ics.zip
[Nexus 6 Themes and Apps] guitardedhero:
Thanks for that, it is the same driver I've been using the whole time.

Have the ViPER zips been installing the driver properly? If so, then all that needs to done is to get my patching script to patch /vendor/etc/audio_effects.conf.
[Nexus 6 Themes and Apps] guitardedhero:
That is different...
[Nexus 6 Themes and Apps] Golf c:
Installs the driver properly every time. As long as I delete vendor/etc/audio_effects.conf first.

ViPER|Audio™ 2.7 Audiophile™ Dark 5x/6p Edition

ViPER|Audio™ Super Quality Driver 1.1 for 5x/6p

Attempt #2​

The two attachments below are for those with no /system/vendor/etc/audio_effects.conf but with /vendor/etc/audio_effects.conf to test for proper ViPER driver installation.

No need to install both, the driver install zip is for those with ViPER installed already experiencing persistent install driver prompt. ViPER|Audio™ 2.6 is for a new install on a clean /system.

These two attachments are testing a different ViPER driver provided by [MENTION=4371701]luigidk[/MENTION].

Let me know the results, thanks guys!
[Nexus 6 Themes and Apps] luigidk:
I think the driver was installed correctly when I used the '2nd zip' provided earlier today "Neon driver" - and then all I had to do was replace the /vendor/etc/audio_effects.conf file with the one in /system/etc/

... here's my steps from the beginning:

1) Flashed: ViPER|Atmos™ 2.5 Audiophile™ Dark by guitardedhero.zip

2) Flashed ViPER Super Quality NEON Driver for 5x & 6p.zip

3) replaced the /vendor/etc/audio_effects.conf file with the one found in /system/etc/

Now - all appears to be working

---------- Post added at 12:24 PM ---------- Previous post was at 12:21 PM ----------

Just saw this - should I flash Super Quality NEON Driver 1.1 now? (or will that be where I am now? - and/or want me to try it out!)
[Nexus 6 Themes and Apps] TorinTPG:
Question - where can I find a compatible rom? I'm new to this, so not sure exactly what is needed
[Nexus 6 Themes and Apps] Golf c:
My understanding is that the Nexus 9 also has a separate Vendor partition. So this should work on the Nexus 5x, 6P, 9, and maybe the Pixel C.
[Nexus 6 Themes and Apps] luigidk:
I flashed neon ... 1. 1 all is good

---------- Post added at 10:59 PM ---------- Previous post was at 10:17 PM ----------

I went ahead and flashed the neon 1.1 zip and i am working fine
[Nexus 6 Themes and Apps] Mr_S:
Flushed the viper:Dolby zip and all is good. Running purenexus latest with hydra kernel. All I needed to do was uninstall old v4a with tb and I was good.

Qq... Will this survive dirty flashes of a ROM?
[Nexus 6 Themes and Apps] guitardedhero:
I see now that 1.1 worked fine for you, I'm thinking it's the different libv4a_fx_ics.so you provided. I'm thinking until I can figure something out, there will be special versions for 5x, 6p, and possibly 9 as previously mentioned. Thank you very much for all the wiping and flashing to troubleshoot this problem so we can finally get something together. I'm assuming ViPER|Audio™ 2.7 works fine after a dirty flash for you if I didn't miss anything.

I'm sorry for not being a little more clearer.

By compatible rom, I mean a stock or custom rom in zip format that you can flash in TWRP; NOT a compatible rom specifically to this sound mod.

Not if the rom installer wipes /system which most do. You can easily queue ViPER to install immediately after your rom zip though. Your settings and everything should be intact and like it was before the flash as if you only just rebooted the phone.
[Nexus 6 Themes and Apps] luigidk:
Very happy to help and many thanks for your getting this to work - I've updated some threads in the 6P forums - to let 6P users know they can get V4A running on systemless root!
[Nexus 6 Themes and Apps] guitardedhero:
Fantastic.

Feel free to start a thread to share the same files, no need for redirection or credit or anything. I'm also moving away from "by guitardedhero" in favor of "ViPER|Audio™" and "ViPER|Atmos™" as identifiers for searching purposes. Feel free to copy anything from this OP as well if you decide to start a thread for the 6p'ers. This was never meant to be a proprietary, exclusive set of info and packages; but rather, to be the "standard" or "go-to" ViPER4Android installer. It only makes sense to me that ViPER|Audio™ works its way into other forums, especially device specific ones.
[Nexus 6 Themes and Apps] TorinTPG:
Finally got it to work! Turns out that my system folder didnt have quite enough prior. I cleared up some junk and installed again - works great! Thanks buddy!
[Nexus 6 Themes and Apps] aalupatti:
Thank you so much

The suggestion from [MENTION=219023]golf[/MENTION]c and these files sorted my issues

I flashed both the files and then made the changes to vendor folder

Now all working

Thank you
[Nexus 6 Themes and Apps] Annunneo:
I flashed the atmos light on my s4 but when I ran viper I didn't get the install driver pop up as with KK versions but when I run it and tick force V4A, in the status it says yes and with my headphones I clearly hear the difference does this mean I'm good to go?
[Nexus 6 Themes and Apps] Golf c:
Yes sir, the zip file automatically installs the Neon Super Quality Driver. That's the beauty of this install.
[Nexus 6 Themes and Apps] Annunneo:
OK because I see yes next to Neon in the status. Many thanks.

Another question where are the Dolby settings?
[Nexus 6 Themes and Apps] guitardedhero:
Did you flash ViPER|Audio™ or ViPER|Atmos™?
[Nexus 6 Themes and Apps] Annunneo:
I flashed viper|atmos 2.5 audiophile.

---------- Post added at 10:01 PM ---------- Previous post was at 09:57 PM ----------

Ahh never mind I saw the Dolby atmos in the app drawer. Would using both it and V4A clash?

ViPER|Atmos™ 2.9 Audiophile™ Edition

Universal​

Thanks to all of you guys for troubleshooting the issues plaguing the 5x and 6p devices. I believe I've got it all sorted on my end and it works great on my Nexus 6 6.0.1 Enforcing and 2.65 systemless root using the driver provided by [MENTION=4371701]luigidk[/MENTION]. All three of my audio_effects.conf files are patched:

/system/etc/audio_effects.conf

/system/vendor/etc/audio_effects.conf

/vendor/etc/audio_effects.conf

This single zip should work perfectly whether you have a Nexus 6 or a Nexus 5x/6p and other devices, of course.

I'd love to get feedback from you guys on this 2.9 before I place it in OP. Just to be sure no lingering files aid in the successful installation, I ask that those that want to provide feedback to dirty flash their rom first to mimic a new user install:

Boot to recovery

Wipe > Advanced > System, Dalvik Cache, Cache

Mount > uncheck System

Install > current rom zip > Queue > ViPER|Atmos™ zip to install next

Wipe > Advanced > Dalvik Cache, Cache

Reboot

Open v4a to verify driver installation and processing

Open Dolby Atmos™ to verify processing

Report your results here.

I'm super excited if this works across the board and can't thank you guys enough.
[Nexus 6 Themes and Apps] Annunneo:
I'm away from WiFi till the morning but I'll be happy to test on my S4 running a cm13 based ROM, plus I have a test build to flash in the morning, dirty of course. I'm new to this thread but not to V4A, many thanks for your hard work and effort.
[Nexus 6 Themes and Apps] guitardedhero:
The combination either sounds better to you or it sounds worse to you and will vary from device to device so it is purely subjective.

ViPER|Audio™ is available for those that prefer the processing to be done by only ViPER4Android.
[Nexus 6 Themes and Apps] Annunneo:
Well having not used the atmos part all sounded excellent with my headphones but I'll test atmos later while watching a movie. Thanks for the help.
[Nexus 6 Themes and Apps] Golf c:
There should be another app in the app drawer. Dolby Atmos. Dial in your Viper app, then open Dolby Atmos and It starts working. I get good results on the open setting with all three of the bottom effects on.
[Nexus 6 Themes and Apps] Annunneo:
Yes I see the Dolby atmos app the drawer.
[Nexus 6 Themes and Apps] aalupatti:
I flashed 2.9 in n6p as suggested but the v4a app is not showing up in the app list. but I see the Dolby app.

So installed the app from the zip file

The app is now showing up but not showing processing in driver status. However shows neon is enabled
[Nexus 6 Themes and Apps] guitardedhero:
Did you wipe System in TWRP first? That is usually caused by an installation over an existing v4a install.
[Nexus 6 Themes and Apps] aalupatti:
Yes.

Did all the steps you suggested.

Even tried copying the .Conf file from system/etc and rebooted. I still no go

Fyi:

I Installed the app from the zip file 2.9
[Nexus 6 Themes and Apps] guitardedhero:
OK, I misunderstood you in thinking v4a was not installed at all.

I have never seen an instance where Force Enable v4a did anything productive. It's hard for me to test the Audiophile™ part of the zip without formatting data but is Audiophile in the list of available profiles to load I'm v4a's Load Effect Profile option in v4a's settings? Load the Audiophile™ profile, begin playing an audio file, open v4a and check driver status. Most times it'll show Processing: No. Simply uncheck Enable v4a box and then immediately check Enable v4a box. It should begin processing after that. Once v4a is processing, that is when you want to open Dolby Atmos™ to test its processing.
[Nexus 6 Themes and Apps] aalupatti:
Actually u were right. V4a was not installed at all after flashing the zip.

Hence I installed it as an app from the zip.

Yes audiophile is available ( I had loaded this a long time ago ) in the list of available profiles

Again loaded this profile and then played a music file with poweramp but still not showing processing
[Nexus 6 Themes and Apps] guitardedhero:
In Poweramp settings:

Audio > Advanced Tweaks

Uncheck the top two boxes relating to volume control
[Nexus 6 Themes and Apps] aalupatti:
Holy cow...... u r a genius....

Worked.... Awesome.. This sorted the misery I was having for the last one month....

Do you have a playstore app that I can donate to ?

---------- Post added at 08:08 PM ---------- Previous post was at 08:06 PM ----------
[Nexus 6 Themes and Apps] guitardedhero:
I accept no donations but thank you for the offer!

I tested even further and the MusicFX button in PowerAmp even works.
[Nexus 6 Themes and Apps] Fuse8499:
2.2 required a little time but I was successful after following OP's instructions. I must say. I just flashed 2.5 right over 2.2 and it works great! 2.5 is so easy to flash!
[Nexus 6 Themes and Apps] Golf c:
The 2.9 zip isn't patching the audio_effects.conf in either Vendor/etc folder. There are two folders, one in system(like the Nexus 6) and a mirror in its own partition. I have to delete the audio_effects.conf in the separate Vendor/etc partition. Then flash zip. Then copy the newly patched audio_effects.conf file from system/etc to the separate Vendor/etc partition. Then it all works. Even works without replacing the file. As long as it's deleted.
[Nexus 6 Themes and Apps] guitardedhero:
That's so weird because I wiped System in TWRP first, dirty flashed my rom, and rebooted to check all directories to be stock with no v4a entries anywhere. Booted to recovery and flashed ViPER|Atmos™ 2.9 and all three audio_effects.conf were patched. Which 2.9 zip did you flash so I can take a look?
[Nexus 6 Themes and Apps] drivel2787:
Same here did this wOrks great. Sounds great thanks!!!
[Nexus 6 Themes and Apps] dgart08:
Possible to make a new flashable that includes the tweaks in the 3 files from the Nexus 5 thread??
[Nexus 6 Themes and Apps] AndrasLOHF:
You could try flashing the the regular test zip in post 1409 of that thread. Definitely make a nandroid though. Do not flash the surround or stereo zip. I'm not sure if the libs are device specific or not and I don't have a Nexus 6. I started this thread when I placed an order with T mobile and after a few weeks when my order didn't ship I cancelled it. With the surround/stereo mix we got going with the earpiece on the Nexus 5 now, I'm not sure if I'm even going to upgrade unless my Nexus 5 gets lost/takes a crap on me. If the zip works fine I'll post it here in this thread.
[Nexus 6 Themes and Apps] aaroncal:
I think its a cm5.x.x bug right now it does it on the g3 as well
[Nexus 6 Themes and Apps] dgart08:
Used the 3 files and it works just fine now...
[Nexus 6 Themes and Apps] KevinChaos:
I used the 3 files and I thought everything was fine, until I plugged my phone into an aux cable and it still only plays from my phone speakers. Any tips? I restored my backup and everything works fine without viper, but I really want to use viper :(
[Nexus 6 Themes and Apps] elevatorguy:
I had the same problem. Try plugging cord in very slowly some google speak now screen pops up back out and all should be good. Boy that sounded dirty ☺. My M8 was funky too had to plug aux cord in before charger or would only pay out of the right side. Hope this fixes your problem
[Nexus 6 Themes and Apps] KevinChaos:
I'll try it, but I even used a different cord and restarted several times without success. It only worked when I went back to stock before I flashed viper, so I don't really think it's the cord.

Edit: I also have an app that opens my music player when I plug in headphones or an aux cable. It opened the app just fine so it's detecting the cord, just not playing anything through it.
[Nexus 6 Themes and Apps] elevatorguy:
I did all that also. Worked on a restore of stock, flash everything only phone speakers happened to plug in really slow got that popup and it worked. The cord probably is good just gotta put it in slow
[Nexus 6 Themes and Apps] badpanda:
This worked perfect. I can tell the difference already.

I didn't even had to uninstall viper I just flashed the two files and done.
[Nexus 6 Themes and Apps] idksomuch:
I actually installed Viper but I have not been hearing any differences in sound. In fact, when I click on Driver Status, towards the bottom, it says Processing: No. So I'm guessing something went wrong, everything else in the Driver Status matches what yours says. I clicked on that link but I'm not sure how to uninstall Viper. Could anyone help me?

EDIT: Nvm, I got it to work. Thanks to all that worked on Viper!
[Nexus 6 Themes and Apps] dgart08:
Will editing our Build prop and lib files cause any issues considering those are tweaks from a Nexus 5?
[Nexus 6 Themes and Apps] badpanda:
Nothing for me so far....
[Nexus 6 Themes and Apps] Turgur:
I did this and it still says "processing: no" running Google music player. This means it isn't working, correct? Any ideas?

How did you get it to work?
[Nexus 6 Themes and Apps] zige:
Is there possibly to mirror? XDA has been slow couple days and attacments isn't loading at all or is loading about 50kb/s, sometime 0 kb/s example now..

EDIT: Now it stopped byself...
[Nexus 6 Themes and Apps] idksomuch:
I went into settings to Disable the app, thinking I would be able to uninstall it, but didn't work. I flashed those three files that was linked in an earlier comment, but since I still had Viper disabled, I had to re-enable it in Settings. Then, for some reason, I flashed the Viper app (from the OP, the one that's just one file) and then installed driver, and it worked for Google Play Music.
[Nexus 6 Themes and Apps] Turgur:
Thanks

Thanks. I noticed SELinux went back to Enforcing so I switched it back and all is well.
[Nexus 6 Themes and Apps] stumpy352:
Do you use greenify? I was hybernating the mode switcher app & that's why it reverts after a reboot. Exclude it from task killers & it will switch to permissive every time after a reboot.

I do. Thank you!
[Nexus 6 Themes and Apps] stumpy352:

2.9 dark from post #1363
[Nexus 6 Themes and Apps] guitardedhero:
I wiped System in TWRP and flashed a different rom to check directories. /vendor/etc didn't even exist. Flashed the zip you did and everything is good on my end, albeit Nexus 6. /vendor/etc now present with patched audio_effects.conf. Sorry man, I thought I finally got it. I really need a 5x or 6p I guess, although I'm sure I can get it working with you guys hanging in there and troubleshooting for me.

Now that I think about it... I remember seeing a while back somewhere about Vendor being a mountable partition in TWRP for Nexus 6p. The topic at hand was irrelevant to sound mods but I'm wondering if you need to have Data, Cache, and Vendor mounted in TWRP for you to get the same results I am getting since I don't even have the option to mount Vendor in TWRP on my Nexus 6.

This sounds very plausible.
