When I am playing music in play music, go to settings then equalizer settings then hit menu key, switch FX compatible mode to compatible. Then with other apps like sound cloud, turntable.FM, earbits, fx compatiable: normal mode works fine. Just keep switching modes and enabling and disabling master power until you find it changing the sound.
[G2 General] alex72:
Before you re-install app, correct procedure is to uninstall drivers first from FX app settings and then uninstall app. Or refer to my previous post. Or seek helpful advice in original thread. I installed app just two days ago without a hitch and all troubleshooting advices I give are from original thread.
[G2 General] vegetaleb:
Did you try DSP manager and Volume + apps?

They don't work on HTC One because of HTC's closed audio drivers but it should on LG as they are close to stock Android
[G2 General] mykenyc:
This app is amazing. As for people with trouble I was using the debloated ROM, so I uninstalled the superuser that came with the ROM, restarted my phone and installed a different superuser app from the play store and that worked for me.
[G2 General] woof123:
I got a problem with this app,sometimes its working sometimes isnt...sometimes the driver is active and sometimes even when i enable it its not..What gives?

Not sure what to do anymore its enabling itself on will randomly....I got the F320S model not sure that it matters tho...any suggestions?
[G2 General] alex72:
I'm using Scott's CleanRom D800 on AT&T. No problems with it. Maybe you should ask developer of ViPER4Android in original thread. It's much more experienced crowd over there.
[G2 General] xdabbeb:
I'd love to hear your thoughts on this if you try it out. Considering the g2 and one of my questions is a viable replacement for the xlouder/noozxoide setup I'm using on my gnex.
[G2 General] alex72:
No, I didn't. If ViPER4Android keeps working I'll never try anything else. It's that good for me. I can't believe what I'm saying because I change things all the time. Oh well...
[G2 General] lattiboy:
Same issues here. I installed busy box and rebooted, then, I reinstalled Viper. So far, so good.

It's so good you REALLY miss it when it stops working.

No idea how these guys seemingly beat HTC, creative, and thx at the dsp game. It's really stunning.
[G2 General] livebyknight:
Finally got it working and it's great. Makes a world of a difference. Reverb and headphone surround are sick on my shure in ears.

[G2 General] alex72:
Thanks for chiming in and telling us what you did to get it working on LG G2. Enjoy the music!
[G2 General] alex72:
What was the problem? How did you resolve it?
[G2 General] alex72:
He already reported back on 3rd page.

"Just got out of my ride after listening to some tunes and man does this really clean things up. Absolutely blown away by the sound coming out of my stock system. From soul to trance to hip-hop, it all sounds great. CLEAN CLEAN CLEAN. As if I couldn't love this phone any more....lol

I highly recommend that you read through the original thread and go through each option to see how it impacts the sound so you can tweak it to what sounds good to YOU. Very very customizable. Blows nooz out of the water, quite frankly." by nismology
[G2 General] alex72:
Go to system/app and mount R/W. Place ViPER 4.x apk in system/app folder with Root explorer or similar and set permissions as rw-r--r--. Reboot. Start the app and install driver....Reboot again.

what is the best profile and irs (speaker) for lg g2 ?

New version (v2.3.3.0) is out!

It includes couple new features like Viper-DDC and Spectrum Extension...Check it out!
[G2 General] ffejy462:
Just curious; after installing the newest version, what does everybody's sampling rate indicate on Bluetooth? Mine is 44100, but I could've swore it used to be 48000. Installed super quality...

Phone speaker playback it's 48000.

Stayed 44100 after enabling aptx also.

Same as yours. In all instances.
[G2 General] bigsnack:
Is there a way to set-up that if I have headphones with a mic plugged in one sound profile is used, while if I have headphones without a mic plugged in another profile is used? I ask because I get pretty great and loud sounds from my headphones(which do have a profile), but then when I use the aux port in a car sound is on the low side, specially when compared to the radio and CD played from the car. Any suggestions?
[G2 General] alex72:
If you mean that V4A automatically recognize different headphones plugged in and choose different profiles based on that, there is no way to do that. You gotta manually load , previously saved profile. Best course of action for you is to make AUX audio specific profile and load it every time you connect with your car stereo. Best ways to raise volume are to raise Output Gain in Master Gate (Limiter) section and to use loud IRS files, like any Studer +6dB. You can play with FireEqualizer as well.

If you're looking for shortcut, you should visit official V4A profile thread and search for similar AUX audio profile set up.

http://xdaforums.com/showthread.php?p=42584030
[G2 General] bigsnack:
I thought there might be a way since my phone recognizes the difference between mic'd headphones and headphones without it. Not to mention if I had say had it plug into the aux port and volume is at it's loudest on the phone, and then take it out and plug in headphones with a mic port, volume is at the level I had it set when I last had mic'd headphones plugged in. But thank you for the reply I will check that out. Thanks.
[G2 General] jrgilbert79:
I'm on an lg g2 vs980 Verizon 24a kit Kat. This works beautifully for Bluetooth but when listening on headphones it works for the first song then stops processing as soon as the song changes forward. If I hit back on the song that was working on my headphones out continues to process.(work) looking at build.prop as suggested for lpa stagefright or tunnel decodes they seem to be missing from the config. 24a KK seems to get sound settings from system/etc media config conf files. What are the suggestions for getting persistent processing on headphones? On a side note speaker on the phone never processes from what I can tell. That included music speakerphone calls pie ringtones.

Edit: Made viper a system app worth TiBU and used app settings in XPosed framework to make viper a resident application forcing it in memory. Didn't change results.
[G2 General] alex72:
What music player are you using? Did you try with some other music players? Anyway, first thing, look where TiBU placed V4A as system app. System/app or system/priv-app? If it's in system/app use TiBU to make it user app again, reboot, uninstall V4A driver first then uninstall app itself. Reboot. Using Root explorer or similar app, mount R/W and place V4A 4.x apk in system/priv-app folder. Set permissions to rw-r--r--. Reboot. Open V4A and install preferred driver. Reboot again.

You are right about build prop entries. I don't have custom recovery so I couldn't flash back missing build prop entries and I didn't wanna do it manually because I don't need it anyway. V4A works for me without those edits.

BTW, V4A drivers should be installed in system/lib/soundfx folder.

View attachment 2696993

Edit; Reference

http://xdaforums.com/showthread.php?p=52037899

And last thing is that you should un-check Resident option in App settings module because you don't need it if V4A is installed in system/priv-app folder.
[G2 General] jrgilbert79:
I'm kinda suck using music unlimited since I have a yearly subscription. But it works so well with Bluetooth I don't understand how the headset can act completely different with a diff output but same player. I did your recommendations and it seems to react the same way
[G2 General] alex72:
If you have custom recovery, you could try flashing back those missing build.prop edits. Search original thread for it and I'll try to attach it to this post as well. Maybe it'll help with Sony music unlimited. Who knows...

Edit; Found it! Flash in custom recovery and let us know if it worked for you.

Unfortunately, I think you gotta do it all over again to properly try this tweak. I mean, you gotta uninstall V4A, install Busybox (if you don't have it), flash attached zip in custom recovery and then reinstall V4A in system/priv-app. Hope it helps.
[G2 General] alex72:
Did you solve your driver install problem? If not you should try this...

Fix for V4A driver install bootloop. With Root explorer or similar app, look for a file named libv4a_fx_ics.so in /system/lib/soundfx/ and delete this file, then reboot. Then, open V4A and install preferred driver, then reboot again. It should fix driver install bootloop problem.
[G2 General] trungbeo:
Thanks, I'm gonna try this.

I Have to delete the after installing V4A right?
[G2 General] alex72:
Yes but only if V4A asks you to install drivers every time it starts...again and again.

Edit; Reference post from [MENTION=1028003]churapa[/MENTION];

http://xdaforums.com/showthread.php?p=52053806

1.- Before installing a new V4A version, from within the still running app, uninstall the driver and Reboot your device.

As soon as it has Rebooted, delete the old V4A from where you had it installed originally and check if the supposedly uninstalled driver (libv4a_fx_ics.so) is still in your soundfx folder (it shouldn't be there) if it still there, as per Joe suggestion, delete it because it somehow wasn't properly uninstalled and reboot again after doing this.

2.- Also check if it is listed in both effects.conf files, sometimes is deleted in just one of the two and that is where the infinite loops asking for driver installation starts (from my experience it is usually the one located in \system\vendor\etc\ the one who gives trouble); if is not listed, include it with your phone's text editor.

Bottom line:

- Make sure the driver (libv4a_fx_ics.so) is uninstalled from the soundfx folder.

- Make sure you deleted the old V4A apk from where you prior had installed it.

- Make sure the driver is listed in both audioeffects.conf files.

And, lastly, always reboot after uninstalling both the driver and the old apk (it means reboot every time you perform any uninstalling or deleting step).
[G2 General] jrgilbert79:
With this and priv app installation it works 100% with Google music still only Bluetooth with music unlimited. Thanks everyone. It's Sony's issue I believe.
[G2 General] alex72:
I suggest to seriously re-consider other popular subscription music services. IMHO, Spotify and Google Music All Access are best out there. Sony music unlimited have problems even with Xperia devices.

BTW, you probably looked but you should look again in Sony Music Unlimited audio settings and disable any audio enhancement it may exist there because it could cause problems with V4A. For example, PowerAmp won't work with V4A unless you disable Direct Volume Control. Maybe you have something similar (or another DSP). Disable everything. V4A alone is more than enough.
[G2 General] ffejy462:
I'm on same phone, and having zero issues. It should be in priv-app folder although.
[G2 General] alex72:
He's been having problems with Sony Music Unlimited app. Are you using same music player?

Edit: xdadebb's 24a, no build.prop edits, aptx enabled, priv-app folder, appsettings module 'keep resident'
[G2 General] trungbeo:
Tried and still doesn't work:

1st attempt:

Can't uninstall driver (bc no driver was ever installed) so I delete the app, install V4A, delete the file, install driver (reboot after each step)

2nd attempt

Delete the app, delete the file, install V4A, delete the file again, install driver

3-n attempts

Playing around with file permissions, delete/install driver but never get the driver installed

Still asking for driver everytime...

Try the APK on my galaxy S4 and it works right away, no need to delete anything? Maybe problem related to the G2 only
[G2 General] alex72:
Did you check both effects.conf files? If driver is not listed (after installation) in both effects.conf files, you need to manually add missing line with your phone's text editor. I attached picture of how it should look in text editor on previous page.

"2.- Also check if it is listed in both effects.conf files, sometimes is deleted in just one of the two and that is where the infinite loops asking for driver installation starts (from my experience it is usually the one located in \system\vendor\etc\ the one who gives trouble); if is not listed, include it with your phone's text editor."

BTW, what ROM/Android version you're on?
[G2 General] trungbeo:
I'm on CloudyStock 1.3

Yes I did check both of them, they are fine with the path pointing to the same file
[G2 General] alex72:
So, you are still on Jelly Bean, right? Are you planning to switch to Cloudy Stock 2.0 (Kit Kat) soon? Last 2 versions of V4A are geared more toward KitKat compatibility, I guess...You can try one more thing to make it work with latest V4A (2.3.3.0)...uninstall V4A again (make sure that driver is not listed in system/lib/soundfx folder) and edit build.prop files following instructions in post #218. If it doesn't work, install older version of V4A (2.3.2.2) which worked for me on Jelly Bean flawlessly.

http://www.mediafire.com/?z1mqg58hz1sfais
[G2 General] trungbeo:
Actually I'm on Android 4.4.2 and V4A 2.3.2.6

Should I try 2.3.3 or downfrade to 2.3.2.2?
[G2 General] alex72:
If 2.3.2.6 works for you, than stay on it 'till you change ROM or new version of V4A is released.
[G2 General] trungbeo:
Yeah but the point is the driver won't install actually :D
[G2 General] alex72:
Then try 2.3.2.2...If you have custom recovery you could flash build.prop edits for KitKat I posted couple pages back and than try latest V4A 2.3.3.0 again...

EDIT

I attached flashable zips for custom recovery (only for KitKat ROMs) so you can try this way if you have custom recovery.

i just want to share my current setup.: AOSB 1.3.2 + Viper4Android 2.3.3.0 = perfect audio for me.
[G2 General] evilboygenius:
After enabling V4A, i only get reduce in volume. I chose Super audio quality while installing the drivers. Someone please help me out. Im on stock ZVC on my LS980.
[G2 General] alex72:
Which music players you tried? No change in volume levels? Something must be completely off because ViPER4Android could be unbearably loud.

There are many ways to increase volume in V4A but I'll tell you couple of them...

First one is Master Gate (Limiter) settings and Output Gain. Set it to 4dB or more...

Second one is loud irs file. Use Convolver and any Studer +6dB irs file.

Third one is FireEqualizer. Raise the bars...

Watch out for your hearing! Settings above could cause serious damage if you're not careful.
[G2 General] evilboygenius:
I used it along with poweramp. Disabled all functions of poweramp equalizer and enabled musicFx (for V4A effects). There is difference in sound but it's less loud than stock when V4A is enabled. I had tried changing options in V4A. I installed the latest 2.3.3.0 and selected super audio mode. I wonder if it's BusyBox issue. Drivers seemed to have installed fine. BTW I'm on ZVC kitkat.

BTW its says "Processing: No" in driver status. Was it supposed to be "yes"?
[G2 General] alex72:
While you play music, processing should be yes. Most likely, you forgot to turn off Direct Volume Control (DVC) in advanced audio settings of PowerAmp. Uncheck it and follow my instructions (just as guidance) for raising of volume levels.
[G2 General] evilboygenius:
I had already disabled DVC of Poweramp. I tried setting Master Gate gain to 6dB. No help. Same thing happens with play Music as well. With V4A enabled, I simply cant get sound as loud as stock. BTW i already tried installing V4A as a system app as well. That didnt help either.
[G2 General] JRJ442:
In Viper, hit the 3 dot menu button to open Settings -> Then select UI Setting and choose Expert.

Then try the extra loud option
[G2 General] evilboygenius:
Yeah I tried all these already. Should I give the old versions a try?
[G2 General] JRJ442:
You could. But the new one should work. This is first time I've heard of it making a phone quieter. I had to turn the Master gate limiter down because it was too loud. There has to be a setting somewhere you're missing. Do you still have PowerAmps equalizer activated?
[G2 General] evilboygenius:
Nope. I don't have it activated. Anyone here who has latest 2.3.3.0 working good on ls980 zvc? If so I will tot back to stock zvc and give it a try again.

P. S. I did flashed the patched kernel via AutoRec. But it was giving me white static lines. So flashed the bootstack to fix it. So I should be back on the Stock kernel right?
[G2 General] alex72:
Wow. First time to hear this kind of problem. Everything works in V4A but unable to raise volume in multiple music apps...Probably kernel problem, like you suspect. Hopefully someone will chime in with LS980 and tell us what ROM/kernel combo works without problems with ViPER4Android.
[G2 General] evilboygenius:
I just tried V4AFX with a fresh 4.4.2 tot install. Straightaway installed V4AFX 2.3.3.0 as a system app and also BusyBox v1.22.1-Stericson. Still I cant achieve any better loudness than stock. Infact it is less louder. Tried changing every adjustments in V4AFX but everything in vain.

Any LS980 ZVC 4.4.2 user who got it working? Please share your BusyBox and V4AFX version combination.

EDIT: Headset does have the sound amplification. But phone speakers only lowers the loudness.
[G2 General] KayIslandDrunk:
Is anyone having issues with viper randomly toggling on and off with KitKat? I'm using it with the stock Verizon KitKat and it'll randomly stop for about 10 seconds and re-enable itself. I never had this issue with jelly bean. I have it installed as a system app and use Spotify for music.
[G2 General] ffejy462:
Install into system/priv-app instead of system/app.
[G2 General] KayIslandDrunk:
It already is in priv-app
[G2 General] ffejy462:
Does it do it on different music players /sources?

Google music has issues on KK I've been seeing.

Poweramp needs to have dvc turned off.

Some stock music players need build.prop edits to function properly.
[G2 General] jrgilbert79:
It's less loud by default because of the shape of the music equaliztion. However put it in advanced mode and increase the dBm at the bottom under master gain.
[G2 General] KayIslandDrunk:
Do we need the build.prop edits on KitKat as well? The OP reads like that's only needed for jellybean.

I only use Spotify for music so I haven't tested other players. I just know it used to be fine before the KitKat upgrade.
[G2 General] alex72:
I was on stock Kit Kat and I had similar problems with Google Play Music (even worse) and I solved it by installing a new ROM, CloudyPro II. I just tried Spotify for half-hour and it plays perfectly as well. If you decide to go this route, when V4A asked to edit build.prop files to disable LPA, I decided not to do it so I skipped that step and just installed Super Audio driver. BTW, by default, in CloudyPro II ROM LPA is set to false (disabled).

In LG G2 stock Kit Kat ROMs LPA entry is not present (missing). If you wanna stay on stock, you could uninstall ViPER4Android completely and flash thru custom recovery missing build.prop edits and after reboot you could flash V4A as well. It will install as system app in priv-app folder. I attached zip files couple pages back, I believe in post #609.
[G2 General] KayIslandDrunk:
Thanks for this. I'll give it a try and report back.
[G2 General] KayIslandDrunk:
So it's working fine for wired headphones now but Bluetooth is totally messed up. It disables and re-enables itself about every 30 seconds with ten second when it's not enabled.
[G2 General] alex72:
Oh, my goodness... Usually, Bluetooth works without problems. I can't remember when someone reported problems with Bluetooth...and I mean here and in original thread as well. Is that only happening with Spotify or with other music apps as well? If you experience that problem only with Spotify try with "fresh" re-install of Spotify app. If you have same problem with other music players, delete Bluetooth profile for your headset and re-pair again. If it doesn't help I'll look for other possible solutions. BTW, did you enable aptX codec in your phone and if not, do you know is your Bluetooth headset compatible with it?

EDIT

I just checked my build.prop and lpa.use-stagefright and tunnel.decode are set to true and my Spotify plays perfectly trough my Bluetooth headset so I suggest you do same set up.

I am on Mahdi ROM and Viper has stopped processing on any music app. I have it installed in system/priv-app. None of the build.prop edits are applicable to me because those lines aren't there... Any suggestions?
[G2 General] alex72:
If you have custom recovery, you could flash attached files in post #609.

http://xdaforums.com/showthread.php?p=52106530

Before flashing, make sure that you completely uninstall ViPER4Android (driver and app itself) and reboot afterwards. Soundfx zip contains super audio quality driver and if you want to install any other driver just don't flash that 3rd zip file but install your preferred driver when prompted to do so. Hope it helps.
[G2 General] JRJ442:
Just because the lines aren't there doesn't mean they don't really apply. If they aren't there, sometimes you need to actually add the lines. I flash that zip that [MENTION=652669]alex72[/MENTION] linked to all the time on Mahdi and V4a always works. With Mahdi it depends on whether you run compatible or normal though. If you use compatible, it works fine. But if you run normal with most music players, you have to plug in the headphones first for it to start processing. Why I don't know. That's the only ROM I've seen where you need to plug them in first.

Hi guys i need your help. I used superlight Rom before and Viper was included and it worked great. I tried pardus Rom it didnt work with pardus Rom. I thought maybe roms fault.

Ps: the installation was successful and yes i did a restart
[G2 General] alex72:
What is your favorite music player? Did you try with some other music players? Probably, you'll need to flash build.prop edits to get it working with your favorite music player.

With PowerAmp you need to disable Direct Volume Control and enable MusicFX in Settings-> Audio-> Advanced Tweaks

Then in the Tone/Volume screen make sure the MusicFX switch is on

Should work then. Try that and report back
