You imply it does not sound as good as you expect, so how has it NOT modified the sound as you expect?

If its "sounds the same" then are you sure it is processing? If you change the equalizer, does it respond accordingly?

If it doesn't, then it isnt processing, but if it does, then it does not sound exactly the same.
[Android Apps and Games] vibrantliker:
Let me clarify, the M11 plus DAP sounds the same as my 2 android phones without using V4a, STOCK.

The DAP sounds no better than my stock phone.

Anyone else missing some way to change profiles fast or even better, automatically? This awesome app should really add a quick settings tile, widget or tasker support to make the users decide themselves. This way we could select a proper profile for music, YouTube, streaming to fit the audio depending on the type of media. :good:

[Android Apps and Games] Chupp4 Jo3:
So I can't seem to install this on my device (lenovo p2) whenever I boot the app it prompts for driver installation but never installs it. (says install successful please reboot every time) but after a reboot the lack of driver issue persists. If I check the driver status it says it can't communicate with the v4a service.

Am I doing something stupid or is this an issue with my device? (Running crdroid with android 8.1 and magisk all up to date as of posting)
[Android Apps and Games] Tecalote:
It's the same on Huawei Devices with Oreo - I guess, we would need (for our models) a permissive Kernel to get this app to work..

Mind that if you use PowerAmp, you will need to deactivate the "Direct Volume Control" on "Audio Engine>Advanced Customization" settings, for Viper to install and let its drivers to process.

[Android Apps and Games] Redhawk2000:
I can't say for sure, but I had this. I also use Sauron so I have AML as well. I uninstalled AML, rebooted, uninstalled viper, rebooted, installed AML, rebooted, installed Viper, rebooted and since then it works. Maybe I didn't do every single one of those reboots, not sure. If you don't use AML, then maybe simply uninstalling the mod via Magisk manager, reboot, reinstall, reboot will fix it. I don't have other ideas myself.

[Android Apps and Games] weriwd:
Did you meant 'Master limiter'? No difference when disabled/enabled
[Android Apps and Games] DiamondJohn:
You turn Viper ON & Off via this switch. are you sure it works when its on (or in either case for you)?
[Android Apps and Games] weriwd:
Yes, I'm sure it does work. It applies changes to the loudespeaker (bluetooth buds as well) when turned on/off, but the loudspeaker sounds way better without viper4android. Disabling 'legacy mode' restores everything to stock after reboot, but I can't tweak my bluetooth buds :/
[Android Apps and Games] DiamondJohn:
Im confused by what you are saying. You say "bluetooth buds as well" but then later say "but I cant tweak my bluetooth buds"? Huh?

As for "but the loudspeaker sounds way better without viper4android" then that normally means the settings are not correct (as in how you like them). Maybe post a pictuire of all your settings for your loudspeaker and try and describe what exactly you dont like about the sound.
[Android Apps and Games] weriwd:
When 'Legacy mode' is enabled, I can change all audio settings, and I have no issues with the Bluetooth devices whatsoever.

However, when 'Legacy mode' is enabled, my loudspeaker is sounds awful and unpleasing. No matter what setting I choose it is worse than stock. Also, the volume steps are not working correctly. When it's 1/20 it sounds way too loud, and I can't go any quieter than that, except 0/20 (silent).
[Android Apps and Games] DiamondJohn:
I have NEVER used legacy mode, so have no knowledge of how it affects the sound output or to the sound routing internal to Android. ie the follo0wing questions may help someone else help you.

To be blunt, it doesnt sound like its really working with legacy mode either. Re-reading one of yur earlier posts, you only need to use legacy mode to get your BT earbuds working with viper? Which version of Viper do you have installed?

[Android Apps and Games] trevtdogg:
not sure how much you want to 'tweak' your bluetooth buds, but if it's just a custom eq setting you could try using the app called wavelet instead. it's made by the viper team, but it's just in the play store for free. it allows you to set a different / unique custom eq default for each audio device that connects, including a separate custom eq for the phone's internal loudspeaker.

obviously it also allows for the default setting for any audio device to be left as system default, so it should do what you want eq wise.

i couldn't get viper working on my phone, so i'm using wavelet instead and am very happy with it!
[Android Apps and Games] weriwd:
Thanks, mate. I tried the Wavelet. It turns out that it works pretty well. The app has almost all of the settings that I have been looking for.

Been using V4A 2.7.1.6 on my Pixel 4a 5G for the past year. All works well except when I try to save a preset, the app (V4A) crashes, and thus no preset gets saved. Any thoughts how to fix this?

Thanks!
[Android Apps and Games] mn1968:
Still no luck with trying to save presets...v4a keeps crashing.

However, I have gotten v4a to work with Android Auto. In settings I toggled on BOTH "Attach audio effects (All sessions but 0)" and "Compatibility mode". The sound enhancements, unfortunately, come thru the "Speaker" settings...but it's better than nothing. At one time enhancements appeared to work via v4a bluetooth settings but I have not been able to replicate that since - audio is always routed thru the speaker settings.
[Android Apps and Games] matt#1:
you can read this comment and check your v4a folder permission. I used to unable to save preset, but after follow him it works perfectly

[Android Apps and Games] mn1968:
Thanks! Works now.
[Android Apps and Games] mn1968:
I have experimented more with v4a and Android Auto. On the phone in Developer Settings I toggled on "Disable USB audio routing". I kept v4a settings toggled on for "Attach audio effects" & "Compatibility mode". I then connected to Android Auto and voila...v4a was processing through the bluetooth settings. I was able to tweak settings and could hear the differences. It was definitely processed via bluetooth settings. This worked for Spotify & Musicolet. When I tried Muzecast , v4a didn't process any audio tweaks. Nor does it work for TuneIn Radio or Audacy.

What's weird though, is now Spotify and Musicolet have reverted back to processing thru the "Speaker" settings - not bluetooth anymore. Even after rebooting the phone and re-starting the car.

Not sure why the bluetooth settings don't process any longer when connected to Android Auto, and why some apps don't work while others do. Very weird.

FWIW - v4a does process bluetooth settings for all apps when connected solely to the car's bluetooth WITHOUT Android Auto, but I have to disable v4a setting "Attach audio effects".
[Android Apps and Games] mn1968:
Just to give a final update...

I have v4a working over bluetooth while connected to Android Auto on a consistent basis. I have AA AIO Tweaker installed and have checked "Disable Bluetooth Auto Connect". The v4a settings I mentioned above remain the same. Now after I connect to Android Auto I need to manually turn on bluetooth from the phone, but I have been successfully getting music processed through v4a bluetooth settings. Spotify and Musicolet work perfectly this way. Muzecast does not process thru v4a until I disable "Attach audio effects". Audacy and TuneIn Radio do not process thru v4a no matter what settings I try...but I don't use those much in the car. They're more like a back-up for if I travel out of state and want to listen to my local stations.

I still don't know why some apps work this way and other don't. They all work as intended when I simply connect to a bluetooth speaker or ear-buds but not Android Auto. 🤷‍♂️

If you don't have AA AIO Tweaker installed you MAY be able to achieve the same results by simply going into the Android Auto app on the phone and disabling "Use Bluetooth". However, I have not experimented with that so it may or may not work as intended...but I don't see why it wouldn't.

Hope this helps someone.

Viper4Android Ain't working on my phone

Hey,

I have Samsung Galaxy M20,

I rooted the device using odin and installed magisk as well, but after i install the apk of viper it says install driver but after installing the driver and rebooting the device viper says that the Driver Status is Abnormal, i tried installing viper thru magisk module but it's still not working.

when i first rooted my phone it was working i installed it thru the magisk module zip. but after that my same phone went into BootLoop so i reset it and now viper isnt working.

If you guys have any solutions please reach me out

(im trying installing viper on the same device)

I am not able to view my old profiles. I tried the fix and flashed it in twrp, it did copied and corrected some files but when I open viper it doesn't show any preset. Files are present in the directory. Please help.
[Android Apps and Games] TheMystic:
Thanks very much for this.

On my OnePlus 8T, I have to install 3 modules (probably in this order), last one being your zip:

I have tested these multiple times on Oxygen OS (both Android 11 & 12, including on clean OS installs), and I can confirm this works on OnePlus 8T. Nothing else is required.

Process to follow:

Flash ALL 3 modules in the attached Viper4Android12.zip using Magisk in the order noted above, even if you don't need Dolby Atmos (you can turn OFF Dolby from System Settings later if you don't want to use it). It is important to flash this Dolby zip because many OEMs include Dolby Atmos in their OS, and flashing this somehow helps prevent the infinite loop of V4A asking to install drivers.

No need to reboot until all 3 has been flashed. Reboot after the 3rd one is flashed. V4A won't ask for driver installation even once. It will just work in Legacy Mode.

Points to note:

1. V4A works only in Legacy Mode

2. Dolby Atmos works too

I'm including all 3 modules in the attached zip.
[Android Apps and Games] TheMystic:
@shadowstep

Are you satisfied with the audio quality from this V4A mod?

I only notice a small improvement. I rooted my device ONLY for installing V4A. I must say I'm pretty disappointed given the results.

I use it only over Bluetooth (Sony wf-1000xm4) and it isn't worth the effort, including other disadvantages of unlocking the bootloader.

Is there anything that can be done to improve the performance?
[Android Apps and Games] DiamondJohn:
Simply installing the mod does very little if anything. The real power comes in when you modify the settings to what you want. Have you set anything up?
[Android Apps and Games] shadowstep:
Like @DiamondJohn said above, just installing V4A won't do anything for you. You'll need to play around with the options, presets, kernels, etc. For me, it improves the quality (of the phone speakers) enough for me to stick to it. For Bluetooth devices, it varies from device to device. So a same preset/option may make one device sound better while a different device worse. There's no "best" present, since everyone has a different ear and like different tone of music (bassy, neutral, etc.).
[Android Apps and Games] TheMystic:
Yes, i did play around with the settings. While I notice differences when making changes, the end result lacks the 'wow' factor.

The Sony Headphones Connect app also has its own Equaliser. Show we keep either that or the one that comes with V4A off?

I remember the first time i installed V4A in 2015 on a Samsung Galaxy Note 2, there was a significant improvement in audio quality. The experience was just amazing (I was using wired earphones then). That phone died on me a few months later, and I believe V4A was the most likely culprit.

This time I'm using the bluetooth earphones. I have done some basic changes like Master Limiter, Playback Gain Control, Spectrum Extension, Equaliser (I find R&B the best among available options for the music I hear), etc.

While each change makes some difference, the end result simply lacks the 'wow' factor. I remember very distinctly how the experience was earlier, and how it is now (same songs, same files).

My wired earphones aren't working using the Type C port on both my phones. I'll have to buy a new adaptor. The earphones themselves are fine, although old now. I wanted to compare the difference of wired vs wireless.

Where do you think is the problem? Could it be that my previous experience set my expectations too high? Or is V4A not very effective over Bluetooth? Or is this V4A mod not as good as other versions?
[Android Apps and Games] shadowstep:
You should keep all other audio mods/equalisers off. Too many cooks spoil the broth.

Not sure V4A can cause a phone to die. Yes, the speakers can go kaput, but that should also be a rarity.

Audio devices have come a long way since 2015, so I get what you mean. Some of them already sound so good that the improvements V4A can make is marginal.

Like I said, the audio devices these days have generally become so good that improvements using V4A can only be marginal. V4A works fine for me over Bluetooth, but my Bluetooth earphones don't need as much of tweaking as my phone speakers, so the improvement is also marginal for me. This has nothing to do with this V4A mod - the app is using the same (closed sourced) drivers from the original V4A app, so.
