[LG V20 Themes, Apps, and Mods] KUSOsan:
Ive tried literally every version of Viper that I could find on these forums, even the other ones like ARISE and there were some (like NATFs 2505 version) that worked for a few times without having to use the blureset but eventually it would need it again and just wasn't consistent. The V20 is slowly dying off development wise so I have to say doubtful that this is going to be fixed unless the problem gets resolved in the Oreo update.

The reason I believe why JamesDSP works and Viper doesn't is that Viper is extremely old and not in development anymore as far as the original creator being involved (to my knowledge) and JamesDSP is open source which makes it easier for other people to contribute to it.

There is another team somewhere on here that took the latest Viper (at the time) and forked it over to their own version to try and continue development. I'll see if I can find the link but I'm not sure if it fixes this issue or not as I'm pretty much using jamesDSP now (it can increase the gain so there must be something interfering with it when you tried it).

All in all I would recommend trying to resolve the issues you had with JamesDSP and continue just using that and forget Viper as Viper is closed source and not in active development anymore. There have been numerous issues on other phones trying to get Viper to work consistently on Oreo and with the incoming Oreo update for the V20, the issues with Viper are prolly just going to get worst.
[LG V20 Themes, Apps, and Mods] BadToThePhone:
Between us we have probably researched, read and tried everything. I wish Viper was still being updated. I'm going to try Jamesdsp again. I've also tried changing selinux to permissive and that didn't help with Viper. The headphone and speaker phone options work for me in Viper, it's the bluetooth that's the issue. I hope development does continue for this phone. Did you install any other audio mods from magisk with Jamesdsp? Thanks for the help
[LG V20 Themes, Apps, and Mods] KUSOsan:
Right now just running jamesDSP but I've tried combos of that + ainur sauron and the audio patch mod for magisk. You could maybe try Lineage OS for the V20 as I think I remember reading someone got Viper fully working without needing the blureset.
[LG V20 Themes, Apps, and Mods] BadToThePhone:
I'm going to see what else I can find. Have you tried any volume or bluetooth mods or quad dacs? Do those affect Viper? There's has got to be a solution. I'm using the Super V20 rom. Thanks
[LG V20 Themes, Apps, and Mods] Paradoxumical:
ViPER doesn't seem to want to run on Oreo for me just yet, the drivers don't wanna stick after reboot. I'm working on it, gimme a minute.

If you're on Nougat, ViPER does process bluetooth, but XHiFi screws up the names for some reason. You could be playing audio over bluetooth, but it'll show up under headphones or speakers. Not sure what's up with that, a reboot corrects it.

Just make sure you followed the rest of the steps. BusyBox, permissive SELinux, the correct install locations, Magisk or SuperSU, etc.,.

The only other piece of advice I have is disabling AudioFX or any other equalizer if you have no processing at all.
[LG V20 Themes, Apps, and Mods] KUSOsan:
It's just a quirk of the V20. Forget the technical details but remember WETA saying that he could never get Viper to process consistently until you force a phone call after already connected to the BT device. So he made a specific app that just forces a quick phone call to an invalid number. To my knowledge no one has been able to fix this issue %100
[LG V20 Themes, Apps, and Mods] BadToThePhone:
This has been the same for me. Bluetooth and Viper are not working right. Maybe an xposed or magisk module can be made to somehow help the processing issue. Can you send me the link to the new Viper you were talking about? Thanks
[LG V20 Themes, Apps, and Mods] KUSOsan:
I PM'ed it to you earlier. Did you not receive it?
[LG V20 Themes, Apps, and Mods] BadToThePhone:
I got it. I'm going to read up on it.
[LG V20 Themes, Apps, and Mods] MEMO#22:
Is there any chance this will work on Lineage OS 15.1?
[LG V20 Themes, Apps, and Mods] mainmast2:
Thanks, I just switched from a Note5 to a V20 H918 and thought I'd lost 2.3.4.0 forever. This works, the Viper4Android FX app doesn't work but the VIPER4Android XHIFI app does with a stock rooted ROM. Bluetooth works with USBapp, Slacker and whatever else I send it's way. I still would like to find a way to get a system wide PEQ and be able to process impulse response files. This is a great start.
[LG V20 Themes, Apps, and Mods] Paradoxumical:
The reason why you have problems with processing (no processing at all or delayed processing) is because Viper4Android is not installed in /system, you Greenifyed it, or you're running it in compatibility mode.

The zip I provided installs the drivers with N.E.O.N and uses an older version of Viper4Android FX for greater audio processing compared to the newer versions and I found it to work/sound better with our Quad Dac. I also included Viper4Android XHiFi because everything else pales in comparision to it's audio reconstruction capabilities.

On a side note, 75 downloads and only two people hit thanks. Now that's highly amusing.

Edit: On another side note, if someone provides me with the original audio_effects and audio_policy files I can probably get Viper4Android to work on Bluetooth without having to use compatibility mode.
[LG V20 Themes, Apps, and Mods] vibrantliker:
That's good to know. I used to use XHiFi for years along side V4A as it gave an extra boost. kind of like dolby atmos. How are the ARISE versions different than yours out of curiosity?
[LG V20 Themes, Apps, and Mods] aaldiar:
So if I have this correct, TWRP is capable of making backups, and it's safe to flash the ARISE/Viper audio mods from the ARISE site? I noticed there's an Exodus DL that's titled LG+BT. I would imagine that would work on the BT problems people are experiencing.
[LG V20 Themes, Apps, and Mods] Paradoxumical:
I have no idea, I've never used it. From my understanding, it's just a bunch of different equalizers bundled together which makes no sense to me. The more equalizers running in the background, the faster your battery dies for a sound quality that probably isn't as nice or sounds exactly the same or(!) a quality that's unable to be differentiated from just good old V4A(s). I also see that it's now system-less? Maybe it's idiotproof, just flash and go without having to change as many settings. You guys tell me.
[LG V20 Themes, Apps, and Mods] slayerh4x:
Yep.
[LG V20 Themes, Apps, and Mods] vibrantliker:
Hard to say what that's for. It's from July.

I'm afraid to restore....did you wipe anything before restoring?

Divine 8.0 works. I'm trying to Uninstall this
[LG V20 Themes, Apps, and Mods] vibrantliker:
What's Divine 8.0?

Here's the xda link. Sorry for the double post. Works great
[LG V20 Themes, Apps, and Mods] vibrantliker:
Can you uninstall with titanium?
[LG V20 Themes, Apps, and Mods] dondadah88:
Yes. That worked but I reinstall divine 8.0 after again and reinstalled the driver and reboot just incase any files got r erased.

This is the best audio mod. And it has dobly atmos no beats but I don't need after seeing what this viper has.
[LG V20 Themes, Apps, and Mods] vibrantliker:
Have you tried ARISE?
[LG V20 Themes, Apps, and Mods] dondadah88:
I don't remember. Tbh with you. I have tried many audio systems. I think arise was with the books of the Bible but I never got it to work right with my note 4 so stuck with divine.
[LG V20 Themes, Apps, and Mods] vibrantliker:
I flashed a version of Arise that's not working right on my V20.

Need to get that uninstalled also.

Does this Divine work on your V20 with no issues, including Bluetooth?
[LG V20 Themes, Apps, and Mods] dondadah88:
I have only used it with blue tooth.
[LG V20 Themes, Apps, and Mods] vibrantliker:
Thanks. Good to know.

---------- Post added at 11:22 PM ---------- Previous post was at 11:12 PM ----------

Dolby working too?
[LG V20 Themes, Apps, and Mods] dondadah88:
I just tried it on speaker and it worked fine
[LG V20 Themes, Apps, and Mods] vibrantliker:
Are you on a V20? Your signature says pixel.
[LG V20 Themes, Apps, and Mods] tnick84:
Probably running google assistant
[LG V20 Themes, Apps, and Mods] dondadah88:
I'm on the v20. I did the build prop for pixel. But got lazy. And didn't complete it. I would of gotten the pixel since HTC made it. And wanted it to live as long as the HTC one or the hd2 but that removable battery sold me in the v20 was to compelling.

[LG V20 Themes, Apps, and Mods] CB620:
So divine is better than the viper that's in the op? And is twrp working now? I have been backing up and restoring through flashfire. [emoji16]
[LG V20 Themes, Apps, and Mods] aaldiar:
I'm still not clear on this, is it safe to flash these things in recovery or are you guys using Flashfire to flash? I'm on the rc8 version of TWRP.
[LG V20 Themes, Apps, and Mods] forty9er:
flashed divine works great thanks!!!!!!

---------- Post added at 05:29 PM ---------- Previous post was at 04:37 PM ----------

Update everything works with divine except bluetooth you can still hear it but no change in sound gonna keep messing around with it thanks again
[LG V20 Themes, Apps, and Mods] slayerh4x:
I was flashing in TWRP.
[LG V20 Themes, Apps, and Mods] vibrantliker:
I tried Divine with bluetooth this morning and nothing on Viper or Dolby. I was like "wtf". I rebooted and it worked!
[LG V20 Themes, Apps, and Mods] CB620:
So is divine better?
[LG V20 Themes, Apps, and Mods] digitalart:
Divine is better it has Viper and Dolby in one but separate apps =)
[LG V20 Themes, Apps, and Mods] digitalart:
Had the same problem with BT but changed driver to compatibility, restart and works now. you should try that as well
[LG V20 Themes, Apps, and Mods] xLegacyGT:
My phone doesnt auto rotate anymore or rotate at all. Anyone else having this issue? Im trying to track down what caused the problem. Ive flash this, installed busybox and one click google assistant.
[LG V20 Themes, Apps, and Mods] digitalart:
You checked your toggles and settings for autorotate?
[LG V20 Themes, Apps, and Mods] xLegacyGT:
Yes, lol.
[LG V20 Themes, Apps, and Mods] digitalart:
Sometimes people overlook most simplest thing and there is no reason for auto rotate not working uses your accelerometer is bad. Get an app or something to test it and dig deeper
[LG V20 Themes, Apps, and Mods] tourbound129:
My auto rotate doesn't work either. Rooted, busybox, Google assistant. Kinda odd really. Worked when I was stock.
[LG V20 Themes, Apps, and Mods] xLegacyGT:
Strange. Hm...
[LG V20 Themes, Apps, and Mods] 533y4:
Just wondering if you ever managed to get the mixer_paths working.
[LG V20 Themes, Apps, and Mods] CB620:
Changed the usual paths and a couple dac hifi lines and nothing changed for me
[LG V20 Themes, Apps, and Mods] xLegacyGT:
I used the one click google assistant and hit restore, rebooted the device and my auto rotate worked. Then I reinstalled google assistant and auto rotate still works.
[LG V20 Themes, Apps, and Mods] tourbound129:
Interesting. I never used the one click Google assistant, I did manual edits.
[LG V20 Themes, Apps, and Mods] 533y4:
Ok. Now I'm deff not an idiot or no obligation when it comes to V4A and audio mods in general. But no matter what I do I cannot get V4A to work no matter what I do. I've tried the OP zip, ARISE 2.3.3, and Divine 8.0. The only one I could get working at all is Divine 8.0 but it only works for the first ten or so minutes and then it refuses to process any audio again (even after closing all apps and rebooting device).

Can someone please tell me how you got it working? Any help? Please and thank you!
[LG V20 Themes, Apps, and Mods] digitalart:
I downloaded Divine 8.0 went to recovery cleared cache and dalvik then flashed divine and after that cleared again reboot and it worked no problem. Only Bluetooth had problems but switching to compatibility made it to work
[LG V20 Themes, Apps, and Mods] 533y4:
Im going to try this from a restore i made earlier (pre-viper). This phone (the v20) seems to be the most "tempermental" phone ive ever come across. Seems like everything has to be done in a very specific order/way or the phone freaks out. Very different than my Note 5 and even old G3.

Is it me or is this phone very picky about how things are done (atleast compared to a Note)?
[LG V20 Themes, Apps, and Mods] dondadah88:
It's not completely compatible. I'm guessing to Android 7.0 LG Ui. I flashed it on my note 4. And I was missing the divine version of beats audio.

I went back to my note 4 until this gets finished.
[LG V20 Themes, Apps, and Mods] Faustous:
Had the same issue. Couldn't even find the Motion Sensor Calibration setting. Rebooting fixed the issue for me.
[LG V20 Themes, Apps, and Mods] jeep447:
I'd say if you're coming from long a stretch of only owning Notes or Samsung devices like a lot of people (myself included), there's probably just no way around the v20 feeling kinda wonky or temperamental at first regardless. I didn't realize how spoiled I had gotten over the years being allowed to have a "fearless" attitude thanks to Odin, and it's not like rooting the v20 was crazy difficult or anything but it sure made me feel like a "noob" again in a damn hurry lol. Anyway so far other than a few unexpected things coming up while rooting everything else I've tried so far has been smooth sailing (knock on wood), but at the same time I haven't really done all that much yet either so I guess I could just be in for a treat lol.

First of all thanks for the link it's definitely appreciated but just a couple of quick questions.. I'm rooted with twrp and busybox installed but I haven't tried any audio mods yet, so if I start out trying this one first should I still delete the audio_effects.conf file like it says in OP before flashing it? Or is that only needed for Viper? Just thought I'd check. Thanks

[LG V20 Themes, Apps, and Mods] Lmax579:
I flashed it and when I go to xhifi it gives me a message that busy box is not installed (which it is) then when I press OK it closes, what do I do?

---------- Post added at 11:14 PM ---------- Previous post was at 10:28 PM ----------

Fixed, what are the best settings as far as output that won't break my phone speakers?
[LG V20 Themes, Apps, and Mods] tnick84:
Man I wouldn't push these speakers too far imo...I did the mixer_path edit changing speaker value from 84 to 90...now they are blown. That god for the warranty lol should get my new v20 tomorrow. Its seems to me that LG went with some cheapo speakers...thread lightly when tweaking
[LG V20 Themes, Apps, and Mods] Lmax579:
Aww damn, I have it on stock but I'm using viper XHiFi, should I keep it on stock or lower it down?
[LG V20 Themes, Apps, and Mods] tnick84:
As long as there isn't any distortion you should be ok...I don't know about long-term though...if I want louder speakers now I'm just gonna Bluetooth to external speaker...
[LG V20 Themes, Apps, and Mods] Lmax579:
That's a good idea, might as well
[LG V20 Themes, Apps, and Mods] tnick84:
Maybe someone can create the surround sound mod to utilize the earpiece speaker with the loud speaker...that would definitely make things sound better...I'm willing to test since I already have a blown loud speaker and a new v20 on the way

I would do it myself but I don't know what lines to add where...been trying to find that but no luck. Anyone?
[LG V20 Themes, Apps, and Mods] Lmax579:
That would be nice
[LG V20 Themes, Apps, and Mods] Lmax579:
For some reason I see it saying that it's not enabled and that processing says no, what am I doing wrong?
[LG V20 Themes, Apps, and Mods] digitalart:
There is a such mod already which makes V20 as a stereo speaker phone :)

Can you explain how you fixed this? Running into the same issue.
[LG V20 Themes, Apps, and Mods] thegameksk:
If we use bluetooth, what version of Viper can we use?
[LG V20 Themes, Apps, and Mods] crazyc78:
Has anyone got this to work over Bluetooth? I'm wondering if it's a known issue and if it does work what steps did you take to get it to work.
[LG V20 Themes, Apps, and Mods] Lmax579:
I didn't fix it, I'm trying to get help on fixing it
[LG V20 Themes, Apps, and Mods] Paradoxumical:
Did you both follow the installation steps provided in the OP to a T?

Particularly the step that tells you to install BusyBox to /system/xbin?
[LG V20 Themes, Apps, and Mods] Lmax579:
Yes we did, and it says enabled : no

Processing: no
[LG V20 Themes, Apps, and Mods] Lmax579:
This is what it says
[LG V20 Themes, Apps, and Mods] Paradoxumical:
That's normal for XHiFi while there's no audio to process (you're not listening to anything), play some music and it'll change.

I see the play button in your status bar, does that application have a built-in equalizer?
[LG V20 Themes, Apps, and Mods] Nitemare3219:
Nope.. thought it said /system/ when it installed. I used BusyBox Pro smart install which went to /su/xbin. That's probably why it didn't work. But now I have a new, bigger issue.

I tried doing Smart Uninstall. It failed after 1 second for an unknown reason. I tried to do it again and said it lost root access. Reboot my phone and root is now gone. Tried flashing SuperSU in recovery again, and it did not fix my root issue!?

Ugh. I have a fairly fresh TWRP backup with root (no other mods) that I plan on restoring when I get home. That should get me back to square 1, right?
[LG V20 Themes, Apps, and Mods] Linsolv:
Having the same problem. I did notice, though, that I had forgotten the step of deleting /system/vendor/etc/audio_effects.conf.

After fixing that, the app itself seems to work, but it does still give me the same error (BusyBox installed to /su/xbin). Very odd.
[LG V20 Themes, Apps, and Mods] Paradoxumical:
Yes, however there was no reason to do the uninstall. You should have simply installed to /system/xbin and BBP would have automatically removed it from /sure/xbin.

Again, install BusyBox to /system/xbin. NOT /su/xbin.
[LG V20 Themes, Apps, and Mods] Lmax579:
Yes it does, it's poweramp
[LG V20 Themes, Apps, and Mods] Paradoxumical:
ViPER4Android is pretty finicky, especially on such a new operating system. Try disabling it, or testing it out with something like Spotify.
[LG V20 Themes, Apps, and Mods] Nitemare3219:
Mine is working now after I did that restore. I should mention though, that for whatever reason, Busybox Pro (stericson's) would not install this time at all. I had to download a different installer and use it instead, which worked fine.

The XHIFI V4A app does not work - it says it needs root access. I have obviously granted it, and root works, but the app refuses to believe it has access. The standard V4A app works fine and is processing.
[LG V20 Themes, Apps, and Mods] Paradoxumical:
Refer to step six in the OP. You're getting that warning because XHiFi looks for SuperSU in /system and Android N requires system-less root. Tap anywhere on the app (except for the pop-up dialog) to make it go away, and XHiFi will work after you select your settings.
[LG V20 Themes, Apps, and Mods] Nitemare3219:
Jeez.. that step went right over my head too! :silly:
[LG V20 Themes, Apps, and Mods] vibrantliker:
Has anyone compared this version to Divine? Are they pretty much the same?
[LG V20 Themes, Apps, and Mods] slayerh4x:
This Viper version has been working great for weeks now, but one issue. I cannot get it to work when I play a FLAC file. The "Driver Status" says unsupported and not processing.

Has anyone got this working with a FLAC file?
[LG V20 Themes, Apps, and Mods] Linsolv:
I guess I misread OP! It still complains about not having an SU binary, but once I click the back arrow, it works fine.
[LG V20 Themes, Apps, and Mods] vibrantliker:
How is this working on blue tooth? With Divine, I have to reboot everytime I want to use blue tooth for V4A and dolby to process. Is anyone having that problem here?
[LG V20 Themes, Apps, and Mods] mcdavid:
after installing 4 or 5 versions of Viper, I decided to use the flashable zip from another thread to go back to stock. I then installed the zip in the OP. The zip installs two versions, the original viper and the XHiFi version. I can't get the XHiFi version to work. So, I disabled it.. But the original viper works perfectly with BT and wired headphones. It is processing 100% of the time.
[LG V20 Themes, Apps, and Mods] vibrantliker:
Do you try Dolby also?
[LG V20 Themes, Apps, and Mods] mcdavid:
No
[LG V20 Themes, Apps, and Mods] digitalart:
I installed Divine 8.0, Viper with Dolby and my Dolby stopped working. Clearing cache and data don't help lol. Viper is great on compatibile to work with BT. Not sure why Dolby stopped. Is there any separate zip to flash just for Dolby?
[LG V20 Themes, Apps, and Mods] mcdavid:
I don't know. I only installed what is in OP. Dolby is not a part of it.
[LG V20 Themes, Apps, and Mods] vibrantliker:
Just search Dolby in XDA and you'll find versions to flash.
[LG V20 Themes, Apps, and Mods] digitalart:
I found a thread bit not sure if it's safe to flash on out v20
[LG V20 Themes, Apps, and Mods] dondadah88:
I was flashing xtreme viper Divine. An a word. And I guess I had a lot of clutter. So I used titaumin back up and removed it then flashed divine 8 and I'm good again

[LG V20 Themes, Apps, and Mods] deltafire006:
Weird I can use Viper XHiFi but I cannot use V4A it says effect control failure, Try to reload the driver and is not enabled, tried reinstalling the same issue happens.

[LG V20 Themes, Apps, and Mods] chronos7:
Yes it does, but today I had to restart the phone to get it going again. This is only my second day with it.

Awesome thanks for the information now I'm excited to flash this!!
[LG V20 Themes, Apps, and Mods] vibrantliker:
What's up with that? That's been my only irritant with V4a and this phone. Viper oftentimes won't automatically start on Bluetooth unless you reboot or plug in a headphone jack then take it right out. Wonder if it has something to do with the dac.
[LG V20 Themes, Apps, and Mods] Mahrenballz:
I've been using Divine and bluetooth always works but what's weird (unless I'm just missing something which is always possible) is that whether I plug in headphones or connect with my bluetooth headphones, the only section in V4A that works is the bluetooth section but it still works and says processing on both?
