OK, I found the links at the bottom of the article

I tried it ut still no sound at all

I uninstalled fix and driver, but viperfx seems to have uninstalled itself

When I try to play music i get this popup

"couldnt play the track that you requested"

I dont know if it makes any difference but I cannot see this directory: /system/etc/snd_soc_msm
[G2 General] alex72:
After you clean up with ViPER Fix app you should reboot into recovery and flash one of suggested Viper Audio zips from post #810.
[G2 General] alrikki:
Yes, I'm not sure how I do that.

I thought I used this root method

http://xdaforums.com/android/development/guide-root-method-lg-devices-t3049772

and not sure if twrp will work with it, I have not installed a custom recovery yet will try to in next 24 hours- but is it too late for me to install a custom recovery?
[G2 General] alex72:
Never is too late but you gotta be careful and follow proper procedure for your phone firmware version. If I remember correctly, I used AutoRec tool for KitKat.

Remember, it's not necessary to have custom recovery in order to have ViPER4Android so if you're not sure how to install TWRP you can try to install previous version of ViPER4Android and choose driver with highest audio quality. Maybe you'll have better luck with it.

I did flash in recovery ViperAudio 4.7.1 zip, I used Autorec.

Now there is no sound. And the driver for V4A doesnt install

popup says driver version 0.0.0.0 /no/no etc

I tried viper 2.3.4.0 also,not sure that it installed.It said failed in red on autorec, same same

I am on lollipop

BUT my only concern right now is to get sound back, for my phone calls etc, so I want to restore asap,easiest way, even if its factory reset or reinstall lollipop ROM
[G2 General] alex72:
I know you don't have sound from your first post #809. I tried to help you with your problem without re-flashing your current ROM but I'm out of ideas right now.
[G2 General] alrikki:
thanks for your help

I just tried to reinstall lollipop, but autorec didnt show up, I suspect I did a factory reset

Some apps are still there, including Viper, but still no sounds

I guess I need a new fone!

I can't find V4A Folder

Hey guys.

I have V4A 2.4 in Ressurection Remix ROM (so, Marshmallow), in a Galaxy S4 Mini.

Viper is really awesome, listening to music became a great experience after I finally rooted, but I want to use some IRS and I just can't seem to find V4A folder... It's nowhere in my internal storage neither on my sd card. I searched manually, using ressurec. Explorer, searching using Windows Explorer when I connect my phone... It's just nowhere. I've even tried to created the folder myself, and I did in some different places (to cover all the possibilities), but it still tells me that the IR Sample Directory storage/emulated/legacy/ViPER4Android/Kernel is empty... (I tried creating folders in different levels of this path, lots of them, none worked.) Could you please guide me on this?
[G2 General] TheHaso:
Go to phone settings, apps, select viper4android, permissions and enable the save data permission. There's only one, just enable it.
[G2 General] mateusonego:
It was already enabled. But I deactivated it, and re-enabled, but nothing changed...
[G2 General] alex72:
Maybe you didn't create /ViPER4Android/Kernel folder at all. You can do it automatically and I explained how at the bottom of OP.
[G2 General] mateusonego:
I've done that tons of times... Just to clarify, I enabled all the permissions when I first installed, then I tried to let it create the folder doing exactly that which you mentioned on the end of OP, but I still couldn't find the folder neither through the stock File Explorer nor through Windows Explorer when I connect my smartphone. Then, I tried to create it manually, so I created lots of folders to try to make it find it. I created folders in all levels of reading of the path it exhibits when it says the folder is empty. Yet, it's still saying the folder is empty... So i tried disabling and re-enabling etc... tried to access the IRS, thinking that it could create the folder, but got no success, and all my created folders are still there, with my IRS files, but it still says the folder is empty...

Can't Copy Files Into Kernel Folder

I'm trying to get V4A working by copying files to the Kernel folder but the copy fails. In ES File Manager I get the following error:

/storage/emulated/legacy ViPER4Android/Kernel/2x.wav open failed: EACCES (Permission denied) I tried this many times but copy failes everytime. I tried using Root Explorer but the app does not see any folders in the Viper4android folder, no Kernel folder. It won't let me create the folder.

I'm running Dirty Unicorns 10.4 on my Galaxy Note 3. I had it working but tried installing A.R.I.S.E. Exodus Aroma. I could not get it to work so I I reinstalled V4A 2.3.4.0. That's when my problems started.

I did a clean install of Dirty Unicorns with nothing else installed except V4A and I have the same copy problems.

Before installing Exodus the V4A folder was in data/media/legacy/Viper4android/Kernel I was able to copy files there. I don't know why the location changed. Anyone have a suggestion on how to fix this? - Thanks.

[G2 General] Grady:
Is there a nice sweet spot setting for this? Like, which sound profile (out of the ones from the zip in the OP) is the best for the LG G2? Or maybe not best but most recommended? Could someone list out each of the options/check boxes/settings that they have selected? Also, does this affect the sound quality that comes through when talking on the phone?

Thanks!

Less is more.

I have Viper Clairty enabled with XhiFi setting and -3.5db. Then I enable Viper Bass with natural default, 50hz crossover, and +10db depending on what I'm listening on (earbuds, studios, car)

Viper Clarity is the real star of this program. I don't mess with convolver stuff as it's just too much DAC and tends to warp the music. The rest of it is interesting in a technical way (reverb, binurial, ect), but isn't really worthwhile to most people in most situations.

i haven't streamed anything. came from an iphone 5 so i have nothing to stream through google yet. loaded about 8 gigs of music from my itunes folder to the music folder on my G2 using the android transfer on my macbook pro. yesterday it would only work with play music and today both. maybe it needs time to settle in. i have no idea because i didn't change anything. i even turned it on an off with the checkbox. other than the noticeable improvement in sound there is a short delay before it kicks in and you can adjust the eq settings from the app. the phone speaker will not work from the stock player but bluetooth does. i have no idea why but i suggest checking it every so often or use play music to be sure. i just happen to like the stock music app.

just tried it with my wireless headphones and it's not working yet it worked all day in the car with the stock music app. probably best to use play music or another app for now it seems

Bugs/Issues

1. Driver status in FX Compatible Mode always NO. Driver status will show YES in normal mode. (No fixes)

Trouble Shooting

1. Uninstall driver, reboot. Reinstall driver, Choose correct driver, reboot.

2. Don't use compatible mode yet, go to sound settings>music effects> and choose v4a(either fx or xhifi).

>>>Test on several players.

3. If not working, switch to compatible mode, reboot, go to sound settings>music effects> and select something else other than v4a.

>>>Test on several players.

4. If not working for some players, activate safe mode, reboot.

>>>Test on those players. If no help, then the player is not compatible. Give up and use a different player for music.

- Driver status shows "Enabled: No, Processing: No", but i already turn on effects and playing music?

A：In FX Compatible Mode, driver status will always show No, but its working.

In Normal Mode means installation problem. Re-install and make sure you did it right.

- Can I still install V4A if I already using other sound mods?

A: Yes, after installation, open V4A app and switch to FX Compatible Mode.

New Viper version (2.3) Coming Soon...

V4A Development Progress (Updated 29-Sept-2013)

FX version:

1. Fixed bugs from v2.

2. Added mystery feature #1, phase 1.

3. Added mystery feature #2, phase 1.

4. Upgraded equalizer to minimal phase equalizer. (Strongest EQ in the world)

5. Optimised speaker sound system, phase 1. Makes all rubbish speakers competitive with iPhone 5.

6. Reconstructed driver installation, app will automatically determine your CPU type and install corresponding drivers. Then, you must choose "Sound quality priority" or "Battery saving/performance priority".

Note: CPU without VFP can only choose "Battery saving/performance priority".

When "Sound quality priority" is selected, V4A is divided into Standard version and Intermediate version.

"Sound quality priority"

1. Standard version - Better Sound quality than previous v2.2.x. EQ using "Minimum phase" type equalizer.

2. Intermediate version - Best sound quality , pure audio without any traces of noise, however requires quad core processor and high battery consumption. We suggest to bring a power bank together. (Release somewhere in v2.3)

"Battery saving/performance priority"

- Sound quality same as previous v2.2.x. EQ using "FIR" type equalizer.

7. Redesigned drivers' architecture logic, remove safe mode(Safe mode no longer needed in this upgraded driver)

8. Added USB audio output support (Such as USB sound card, speakers, headphones)

9. Fixed bluetooth headphone detection/identification problem.

10. Added auto detect CPU type for driver installation.

11. Updated driver installation module, increase installation success rate.

12. Improved background noise problem, for CPU with VFP or better (90% CPU in the market, you can use 3rd party apps to check CPU information whether VFP or NEON written anywhere)

13. Secret - Hugely improved 1 feature.
