Working great in headset mode. Absolutely no sound in speaker mode though. Any one else facing this issue?
[Android Apps and Games] 16luuk:
EDIT: i flashed stock rom again, and installed the viper4android APK again, and it did install the driver. when when i try to listen to audio it doesnt change.(i don't hear a difference)

im using a samsung a5 2017 with rooted (supersu) stock rom.

any solution?
[Android Apps and Games] lauralbaby:
It took me a couple of reboots before switching on Viperfx master switch worked.
[Android Apps and Games] flex1911:
There is no need in quoting the whole OP, everyone understands you without it.
[Android Apps and Games] kalpik:
Are there any updates on the new version which is supposed to fix the FC on switching to Bluetooth?
[Android Apps and Games] shadowstep:
Not yet, the developer announces here (including an update to the thread title) when an update is released in xda labs.
[Android Apps and Games] 16luuk:
I have restarted my phone about 8 times now, it did not change anything

The driver status in app says the following

Driver version: 2.5.0.4

NEON Enabled: No

Enabled: No

Status: Abnormal

Audio Format: Unsupported

Processing: No

Sampling Rate: 0

any suggestions?

since im using a Samsung A5 2017 with stock rom, do i need to do anything else than only installing the app and drivers thourgh the app?

(like disabling the default audio EQ app's or something?)
[Android Apps and Games] lauralbaby:
Did you install from Magisk or the XDA apk? I'm using the latter, along with the magisk Audio Modification Library module.
[Android Apps and Games] 16luuk:
I have SuperSU as root so i cannot use the magisk module. i installed the apk and thus the driver from the apk that the OP has provided.
[Android Apps and Games] Nochaz:
I have v4a working on my OP3T running the latest LineageOS ROM. Installing from Magisk worked for me. My only problems are 1. Bluetooth is not being processed. 2. Pausing the music makes v4a stop processing upon unpausing. I have to keep force stopping stuff to make sure it's processing. I haven't been able up uninstall AudioFX, so maybe that's messing it up. It's a great program though, and I thoroughly enjoy it when it's working. I definitely recommend getting Viper-DDC working. I got a file for my V-Moda M-100s and the sound is amazing.
[Android Apps and Games] hllywd:
I found another work around for when V4a stops processing. Instead of doing the force stop route, go in viper settings and turn on attach audio effects and turn it off again. It does nothing turning it on, and leaving it on, until you turn it off. A little quicker than force stopping viper.
[Android Apps and Games] _conors_:
I have no words to say how much I love this app.

Thank you so much for all your efforts to keep it up, working in Xiaomi Redmi 4A (Paranoid Ten)

Regards.
[Android Apps and Games] Nochaz:
lol a few days after posting this Viper is running fine now. Well actually Bluetooth still doesn't process, but the pause issues are fixed. Very strange!

Guys hello...

I recently installed viper on Pixel experience and works fine as it seems....

Do I also need to install audio modification library and audio compatibility patch?
[Android Apps and Games] gil80:
Hi.

I just upgraded from 2.6 to 2.7.1.6 and I cannot use my ddc file. it directs me to ask for it in telegram. I also don't have the option to load my profiles that I created in 2.6.
[Android Apps and Games] jazzyd1:
Only the location for these files have changed to /Android/data/com.pittvandewitt.vperfx/files. So copy your available DDC, Kernel and preset folders here. Everything should work fine.
[Android Apps and Games] gil80:
no such folder as /Android

Also, I'm missing the menu to load/save profiles.
[Android Apps and Games] Wishmasterflo:
It is inside the DATA folder there.

For loading profiles just press once on the Icon not long press.
[Android Apps and Games] gil80:
so the folder path is: /data/data/com.pittvandewitt.viperfx ?

The /files folder doesn't exist. Should I create it and then move things there? seems odd to have to write to that folder. Why was it changed? much more comfortable to have it in the /sdcard
[Android Apps and Games] MaverickNextDoor:
The "/Android/data" folder is in the root folder of your internal storage.
[Android Apps and Games] gil80:
got it!

[Android Apps and Games] Maflo:
Good morning all,

I used Rootless installer (v4afx-rootless_03.17.2020.zip and i install the Apk for Xda). Everything works perfectly.

One question: how do I uninstall it? Uninstall system crashes when I want to delete the application

I need to uninstall it to update my custom rom. (Pixel Experience 10 Plus/Android 10)
[Android Apps and Games] shadowstep:
Dirty flashing your existing ROM will remove the changes done by the rootless zip.
[Android Apps and Games] Maflo:
Thank you. This will delete the drivers installed by the file "v4afx-rootless_03.17.2020.zip" but concerning the installed apk "VIPER4Android Fx"? Unable to uninstall ...
[Android Apps and Games] shadowstep:
I haven't looked at the zip, but if it installs V4A as a system app, it'll be removed too.
[Android Apps and Games] Maflo:
even without installing the driver zip, once the apk installed, it is impossible to remove it. If I want to uninstall it, the uninstaller crashes.
[Android Apps and Games] MaverickNextDoor:
Try using a terminal emulator or ADB to uninstall:

- Get the package name of Viper apk.

- type the following command: pm uninstall package_name

where "package_name" is the Viper apk package name.

XDP-300R

Could someone help me Please.

I have a Pioneer XDP-300R that I've rooted and I can install Legacy Viper4Android. It works just fine with Aux out or using headphones etc. Whenever I try to use USB out then I get ''status abnormal'

I tried updating to this new version. I've installed Busybox and it still won't install it says 'make sure your device is rooted' - but it is.

Magisk module won't install it says that my API is 22 or something.

Is there anything I can do? This device has Lollipop

I was happy with the Viper4Android Legacy but I want to get it to work through USB out. Please help!
[Android Apps and Games] MaverickNextDoor:
Is "Disable USB audio routing" on in Developer options?

Does the "new version" have a legacy variant? The apks I know of are for Marshmallow and above, and you're on Lollipop, so it won't install (ought to give a cannot parse this package error).

Just my thoughts.
[Android Apps and Games] LDBaha:
Disable USB audio routing is off. Should it be On?

I can't install v2.7 because of the parse error thing. I can't find any legacy versions of 2.7.

I found a 2.5 version that installs but then it won't install the driver. The app requests busybox and even with busybox installed it won't install the driver.
[Android Apps and Games] skalnas:
Thanks for the android 10 version, working on my moto g7 power unofficial lineage 17.1. I was able to convert most of my old profiles.

Thanks!
[Android Apps and Games] MaverickNextDoor:
Disable USB audio routing should be off by default.

I don't know, but maybe you can install "osm0sis busybox" (available somewhere on XDA in zip form) via TWRP.

Cheers.

Can somebody provide magisk module zip for the previous version? I just updated my Mi A1 to Pie, but after each reboot V4A just keeps on asking to install the driver.

[Android Apps and Games] Wishmasterflo:
No you need to be rooted in order to get V4A to work.

I have audio fx in my system by default (android 10). Now if I try to flash the viper magisk module (Magisk version- 20.4), will it cause any problem or crush?
[Android Apps and Games] MaverickNextDoor:
No it shouldn't. Installing V4A apk automatically installs its Magisk module. But disable AudioFX via Settings or Terminal Emulator/ADB so it doesn't clash with V4A.

Question about Playback Gain Control

Afternoon all,

I recently moved from a Nexus 9 running LOS 7.1.2 to a Samsung GT2 (T813) which I put LOS 16 on. At max volume videos played back via YouTube (in browser or via the app) on this GT2 are FAR from loud compared to my old Nexus 9. I've never had a need to seek out something like V4A so I wanted to ask --> am I right to assume that "Playback Gain Control", when enabled, is universal across the device?

Audio problems

Hey all... is this still in development or is it finalized? I'm on a Pixel 4 XL (Android os 10) and I was wondering if maybe this app would fix some of my audio problems? I'm having a tough time getting my audio to work right. Some things are extremely loud, like video games and other things are extremely quite, like my ringtone. I would love to be able to get the volume controls separated. If I could stop the ringer volume from changing the loudness of my notification sounds that would be great! Also the audio on my device is not ready that good. It has way too much treble in it for me and needs to be adjusted somehow. Yes, I'm rooted. ;)

Would this work on my device and are people still developing this?

Are people still developing modules for Magisk Manager? When I go to the downloads section in that app there is not a lot to choose from anymore. I just came from a Google Nexus 5 device (back in December) and there were tons of modifications for it but for my new Google Pixel 4 XL I'm not finding a lot of stuff for it. Any ideas or links would be greatly appreciated.

TIA
[Android Apps and Games] Soumy1234:
Yes this is still in development. Updates aren't released often, only when needed. I'm not sure if this will fix your issue with somethings being quiet and others loud, but it definitely can fix your high treble problem.

Magisk repo recently got cleaned so that's why it seems like there aren't many mods. Also, if you're thinking about the Dolby mods, you can find them on XDA, and they work well with V4A. I hope this answers all of your questions.
[Android Apps and Games] marciozomb13:
What you need is a custom kernel with audio settings.

After installation of 2.7.1.6 apk, installed version says 2.5.0.4!

The so called 2.7.1.6 version works like a charm :good:. However, there's a minor nitpick - post installation, the version shows up as 2.5.0.4! I can even see the new changes from the changelog (long press to show description etc.). Unsure if the driver follows a different version numbering from the app, or if there's an old version string lingering around.

Also, is it possible for Viper to obey the font used system-wide, instead of using its own?
[Android Apps and Games] Lughnasadh:
Yeah, 2.5.0.4 is the driver version.

As for fonts, I'm using the Magisk Mod Font changer and it doesn't change the fonts on V4A. Not sure if there is a way for it to obey they system-wide font. Others may know better.

Help does not make me install drivers.

-Installation

1-I install apk I restart the phone

2-I open the program it asks me to install the drivers, I press ok, it asks me for the permissions I grant them it restarts.

3-after the restart i open the application and it tells me to install the drivers.

4-It does this all the time and does not install the drivers how can I fix it?

EDIT: I have the stock ROM firewall 432 eu

[Android Apps and Games] timbuctoo:
Option to save/load presets needs to be explicitly mentioned somewhere in the app

I agree. Seems like an Easter egg the way it's currently concealed! Why can this not be exposed as a menu option, or some button?

I installed HavocOS (Android 10) on my oneplus yesterday. Like always, installing viper is one of the next steps. But it does not work. I can install the app and the driver, but audio is never processed - BT, phone speaker or headset

[Android Apps and Games] lottarake:
Using latest Magisk Canary? If so, need to go back to an older version, ideally 20401, as the newest breaks most modules including V4A. I'm running Havoc as well on my OP7 Pro and reverting fixed V4A and AML not processing anymore.

Does anyone get 48Khz processing over Bluetooth?

My onePlus+1 supports has bluetooth 4.1.

In the Developer Mode I see that I have several bluetooth codecs. The default is AAC. I try to get it to save aptX HD but it doesn't save it, even though I installed aptX HD Bluetooth Hi-Res Audio Codec.

My headphones support aptX HD (Nura phones).

Appreciate any help.
[Android Apps and Games] fastleo63:
I have a OnePlus One, too.

Although in some ROMs the aptX HD codec option is present, I think that it also needs a specific hardware, unfortunately not implemented in our OPO.

The first OnePlus with aptX support was the OnePlus 3.

For more info about compatible products:

[Android Apps and Games] bombadier:
How did you get viper working with android auto? I don't use android auto in my golf because it sounds terrible without viper.
[Android Apps and Games] NotATreoFan:
It uses the BT settings for me, even through the phone is plugged in with USB. When I tried on my last phone, OP7 Pro, I had to force stop the app and start it again while music was playing, but so far [fingers crossed] that hasn't been necessary on this phone.
[Android Apps and Games] bombadier:
Have just had another go with my Pixel 3a trying to get it to process over bluetooth, tried your suggestion of FCing and restarting it with music playing to no effect :( did some more fiddling about, not actually sure what I did but when I opened viper it jumped to bluetooth from speaker and started processing ! have just tried again to get it working and am unable to recreate whatever I did! looking for ideas on how to troubleshoot this?

Thanks for your reply, given me some food for thought and will keep trying over the weekend and see if I can work this out and get it working consistently
[Android Apps and Games] surajloharia:
I usualy face this after a call, try this ...

Open terminal and type su -c killall audioserver

And then toggle the attach audio effect toggle. Or just for luck force close the viper and re run

This worked for me
[Android Apps and Games] NotATreoFan:
Unfortunately it's a little inconsistent on some devices. I'm not using AA that much at the moment, with barely driving anywhere, so we'll see if it keeps working this well.
[Android Apps and Games] nousernamesorry:
Hey, I'm having a small issue.

I recently installed this on my OP6T, and it says everything is installed, and drivers enabled,normal and supported. But when, I tweak the eq or anything else for that matter, nothing happens to the audio. It stays the same.

Unless, I go the settings and turn on "Attach audio effects", then I can notice the difference and it working. But that makes other apps not work.

Suppose if I'm using YouTube music in the background and the music is playing, and if I decide quickly watch a video on instagram, the music will stop, but the video won't have any audio, same goes for YouTube in browser, but if I pause the YouTube music and clear it from my recents, then the instagram/YouTube videos will play normally in audio.

I'm assuming that's what "attach audio effects" does.

But if I disable that, none of the effects like the eq or viper bass etc work. None of them are applied, and it shows processing "no".

Am I missing any step?
[Android Apps and Games] :
how to use ainur audio n viper at same time?

can this combo make conflict
[Android Apps and Games] surajloharia:
Flash Audio Modification Library (AML) .. It won't conflict as it works on Unity

---------- Post added at 01:03 PM ---------- Previous post was at 01:01 PM ----------

Turn on compatibility mode from Viper and attach audio effect as name implies will attach the effect to only single app you are using in foreground and have you flashed AML ??
[Android Apps and Games] nousernamesorry:
Yea, tried compatibilty mode. Effects work, but switching apps issue remains.

If I use AML, my bluetooth breaks completely.

Without AML, bluetooth works, but if im listening to music on youtube music, and switch to instagram (or any other app) youtube music pauses, and instagram video stays muted even though it has audio.

( Tried compatibility mode - same issue, tried attach audio effect - same issue, disable compatibility mode - same issue, disable attach audio effect - same issue)

( AML installation breaks bluetooth audio, normal phone speaker works, but bluetooth audio does not work)

Please help me out, this is driving me nuts.
[Android Apps and Games] NotATreoFan:
Did you follow the steps I posted? They worked perfect for my 7T Pro.
[Android Apps and Games] nousernamesorry:
Followed your post step by step.

That nearly did the trick, but if i switch to bluetooth and try to play youtube music. And scroll through instagram/other app, and a video plays, youtube music pauses, but the video on the feed remains muted though i have unmuted the video.

Only happens for bluetooth, everything else works fine. Any clue what am i missing?

Inversely, if i am using youtube app, and switch to youtube music to play it. Youtube app stays paused, whereas the youtubemusic app starts playing, but again without audio. To get my instagram audio working again, i need to restart instagram. Then it works. is this a bug?
[Android Apps and Games] shahfaishal:
On A10, it was working well but since AML got update to v3.5(54), it stopped working (screenshot provided). I uninstalled them and tried installing them but it still says NO in both ENABLED and PROCESSING tab in settings. Take a look as i tried twice!
[Android Apps and Games] NotATreoFan:
Looks like the few times it worked has come to an end. Had to run some errands today, and V4A had no issue when bouncing between multiple BT devices, but once I tried AA, it would not process. No luck with a force stop or playing with toggles in the app, either. However I was able to get it working again over straight BT without a reboot or anything. Just seems to be very picky with AA.
[Android Apps and Games] mixlex:
Are you able to try going back to the earlier AML version?
[Android Apps and Games] Aaskereija:
switched from omnirom (worked perfectly fine) to lineageos (android 9) and can't get it working, it works right after boot but if i start another app it stops working. tried everything even with audio library. It's on a Sony Xperia X
[Android Apps and Games] bombadier:
Aye this is a game of frustration that I am not going to play, nothing I try seems to work and am starting to think that one time it worked was actually because AA wasnt properly connected, the phone was paired with the car, the minute AA connects it kills the bluetooth connection and music sounds rubbish because Viper is being bypassed, wish there was some constructive way to troubleshoot this, viper is meant to be capable of working over USB, why not with AA? Grrrgh!!!
