Fixed

Never mind. fixed it myself. Got viperfx working now and really feeling d beat. But works only on my stock music player. Not on my poweramp, not on maven player pro, not on my google music player. I'll fix that later.

Ooooohhh mmmyyyyyyy mother-effing gosh. Got it to work on all music players. Loving it most with poweramp and never taking off my headphones. Thanks xda:good:

I installed 2.3.3.0 on my Nexus 7 with 5.0.1. I had to set selinux to permissive and uncheck use nuplayer in developer settings.

Since 2.3.4.0 was updated to address lp issues, I'd try unchecking use nuplayer and try again. If that still doesn't work then set selinux to permissive, and try again.

Have to load effect profile twice?

Hi, When loading an effect profile I have to load it twice for it to start being used. Either that or load the effect profile and then disable/enable V4A to get it to use the new profile. Does anyone else see (hear) that? Using Galaxy S3 on Jellybean 4.3 (version 2.3.4.0 installed as system app). Any fix available? Steve.

Were LP version?
[G2 General] JRJ442:
2.3.4.0 should work on LP. If you're running AOSP you can do a search for Lolliviper. A version will pop up that's a flashable zip. Flashes libs and stuff in recovery. Stock ROMs just copy/pasting the apk in Priv-Apps should work just fine. I think anyway.

Really you should just play with the settings yourself. Everyone's ears are different. Personally I like tons of bass.
[G2 General] ffejy462:
I had to set selinux to permissive for Viper to install and work properly. Previously nuplayer had to be unchecked on 2.3.3.0, but apparently that's no longer the case. Installed on 39a and on stock Nexus 7 5.0.2 (haven't got around to installing it on 5.1 yet).

Then go to /etc/init.d directory, create a file and rename it as "08setperm" (without quotes) and add the below lines in the file and save it..

#!/system/sh

setenforce 0

And give full permission (rwxrwxrwx) .. Use root Explorer to edit and give permissions..

Now hard reboot your phone and you can see SELinux is set to "permissive" on boot itself..

Or (without init.d):

Worked fine for me. 39a VS980.

Installed in /system/priv-app, set permissions to rw, r, r, did not uncheck nuplayer, set selinux to permissive, super high quality, no build.prop edits, poweramp.

Other than selinux, exactly the same as KitKat for me. Worked in normal mode without issues (including convolver).

[G2 General] mannequin:
interesting. the more i'm reading about V4A on LP, the more i see the reports that it only works in Compatible mode. like i said, for me it's definitely the case and i'm using PowerAmp too. on top of that, Compatible mode doesn't play nice with any streaming apps. there's a custom audio_policy.conf file posted in the official thread to resolve that but on my device it just broke all audio completely.
[G2 General] ffejy462:
Using V4A on a Nexus 7 with stock 5.1 as well. The installation was identical. Normal mode on it as well. The only differences is I'm not using convolver or poweramp.

I'm assuming you've set up poweramp to work with v4a... Dvc off, eq off, tone off, limit off, music fx on, gain off, I have audio buffer at +750ms, and audio thread at +3

i never had problems with V4A on KK, everything just worked, all the time.

having spent some time with audio on LP, i don't think the overall sound quality is the same as KK on my particular device. is it worse? hard to say, it's not better that's for sure. more so , i noticed that PowerAmp introduces artifacts no matter what the sound settings are (even without V4A enabled), something i never encountered on KK either. Google Music plays local files just fine, however, V4A or not. again, i can only judge V4A performance in Compatible mode. slightly disappointed about the whole ordeal since overall LP experience is quite good.
[G2 General] Alphas:
I am running KK4.4.4 on a headunit and when the unit goes into sleep, V4A does not activate upon resume, how can I fix this?
[G2 General] ffejy462:
Install Viper in /system/priv-app folder. Set permissions to rw, r, r. On lp you need to change selinux to permissive (make permissive file in sdcard folder if on xdabbeb's roms). Reboot. Open Viper, super high quality, reboot. Set up as needed. Depending on player, you might need build.prop edits, but I didn't with poweramp (you do need to correctly configure poweramp though). I didn't need edits with tidal, Spotify, or Pandora either.

[G2 General] phoenix_rizzen:
It should just work. I use it with Podkicker, which doesn't include any kind of internal equaliser, and V4A alters the audio as designed.

It's apps WITH internal equalisers that you have to mess around with.

ViPER4Android v.2.4.0.1 released.

Update log: February 1. 2016.

Fixed a legacy from the first edition of the bug. The bug can cause V4A power consumption increases, bringing background noise, the background often killed and so on.

Highest sound quality and power-driven one, both.

Added "AnalogX" sound, the sound for the analog amplifier characteristics Pure Class A amplifier, bringing warm mellow tone.

Canceled support for non-NEON CPU's.

Just a heads up for possible solution for anyone struggling with drivers installation or basically any other problem with ViPER4Android. You should try previous version of ViPER4Android which supports ROMs up to Jelly Bean 4.2.2. As you already know, G2 is shipped with 4.2.2. Maybe this version is better suited for our devices. Link

OK, I gotta ask, is anyone worried about the Chinese and the fact that it requires internet access and root? Not trying to be a d€^k, just curious.
[G2 General] lattiboy:
Ugh. It is working, but MAN do they need to simplify the setup.

Here are (IMHO) the bulletproof steps:

Root your phone

Install Busybox. I used Busybox Pro and installed whatever that version is.

Install the old version

Run app, grant SU

Install the driver from the in-app menu

Reboot phone

Do the "convolver" enable/disable thing and drag the files into the folder (see first post)

Go into app and change FX mode to "compatible mode".

REBOOT PHONE

Listen to music.

PS a lot of the time,

when it is clearly working, the processing bit will say "no".

It's still working, but the easy way is to simply enable and then disable the first checkbox in the app. You'll hear a minor pause and the sound will change dramatically.

PPS Viper is super effective with two particular types of music: bass heavy techno and multi-instrumental organic. The two tracks I've been most impressed with are DANCE by Justice and Postcards from Italy by Beirut. The middle section of Postcards is astounding when you have the XhiFi enabled.
[G2 General] alex72:
It's explained in original thread. It just checks number of installations. It's safe, reported by people who know how to read code. Anyway, it wouldn't be that hugely popular if it's a malicious app.

So for me...this app works perfectly. I did figure out what it does and doesn't work for though.

Everything that I uploaded a long time ago to Google music with the music manager from my personal collection does NOT work. However I have their unlimited streaming service, and all the songs that I add from Google even when downloaded to my device work perfectly. The difference is quite amazing. I guess it's time to delete my library and just add them through Google instead.

Just to be sure...you downloaded the files from the zip in the OP and placed them into storage/emulated/0/VIPER4Android/Kernel folder right?

And then after that, you enabled the convolver option and chose a sound profile? And you've verified that your su app (whatever that may be) has been granted root access?
[G2 General] umair239:
Exactly, I've followed all the directions step by step just as listed here and in the original thread. The Kernel folder is for irs files only and they do show up when I click on impulse. But right after root access I get the message Viper4Android failure.

Tap Menu (3 dots in top right corner) and tap Load Effect Profile. You should see Audiophile profiles. If you don't see it than you probably didn't place downloaded files in Internal Storage/ViPER4Android/Profile folder. Same goes for irs files. They have to be placed in Internal Storage/ViPER4Android/Kernel folder. You likely extracted and left it in Internal Storage/Download folder.
[G2 General] Romagnolo1973:
Yes my bad, now it is working. I don't like all those mods, I prefer V4A normal without beats or audiophile, but this zip file installed via recovery is a good and easy way to put Viper on our G2 whit no issue.
