Huge battery drain since 2.7

Hello guys, after hours and hours of searching for the reason why my battery gets drained a lot quicker suddenly, I finally found the problem: Viper4Android in the version 2.7.

I have a Galaxy S7 (G930f), running a touchwiz based custom ROM and rooted with the latest Magisk and having Greenify as task manager. I've had this software configuration (Magisk + V4A + Greenify) for some years now since my Galaxy S5 and never had problems with it so far, until I updated to 2.7.

I already updated and reflashed the ROM several times thinking that the problem was maybe a ROM problem, but finally I realized that it is not.

While listening to Spotify with the screen off and every other app shut down (using Greenify, V4A obviously not shut down), I am losing almost 30% battery per hour, which is a bit much regarding I currently work a 6 hour shift and thus needing to recharge my phone once during the shift and up to twice a day if I constantly listen to music.

Even while doing nothing (phone at standby, screen turned off, but Ringtone enabled), I experienced a much quicker battery drain than usual.

The thing is, V4A isn't listed in the device's battery management graph, not even as running in background.

After disabling the master switch in the app (not even uninstalling V4A completely), I am using under 10% battery per hour while listening with Bluetooth headphones, which is the usual and normal state.

In standby, the phone would now probably last for weeks.

Is this battery drain a known topic or am I the only one experiencing this problem? I've been using V4A for years now and actually don't want to throw it away..
[Android Apps and Games] mixlex:
Legacy continues to perform more consistently for me, why don't you just switch back as I have. I didn't have the battery drain with the newer version as you have. I had problems when switching from one source to another. It would stop processing and it was difficult to get it processing again. I prefer the older black n cheese legacy version. No problems whatsoever. The newer version must work fine for many users, but unfortunately, not for me.
[Android Apps and Games] Peter.1997:
Will try that, although I always had problems with the old versions. V4A was not processing any more after the phone was turned on for some hours, only changing to compatible mode or restarting the phone worked..
[Android Apps and Games] ryaniskira:
Has anyone gotten this working on Android 10? No matter what I do the driver status is always abnormal and audio format unsupported.

Pixel XL Android 10.
[Android Apps and Games] Wishmasterflo:
Yes it works for me on Android 10 .
[Android Apps and Games] ryaniskira:
How? I've tried installing via the app, installing the rootless driver then installing the app, I've tried the magisk module, everything and nothing will work.
[Android Apps and Games] Wishmasterflo:
I have a guide for this at home. Can post it later.
[Android Apps and Games] KapilNagpal01:
Take care of 4 things it should work

1. Master limiter is turned on. Speaker switch if you are trying on speaker or respective switch if you are using headphones.

2. In settings switch on Attach Audio Effects and also Compatibility mode.

3. Choose pi music player or similar player which gives you option to choose equalizer, from there choose system equalizer and discard players own equalizer.

4. If still issues, force stop music player, viper and then start viper first and then music player. If still says not processing just toggle the switches in point 2 once or twice and master limiter switch It will definitely process.

Wish you good luck.
[Android Apps and Games] sufy1000:
Anybody know how to fix it? It comes in my notification bar as processing (speaker) but when i check in the app it says no for processing.

I've tried installing the audio modification library but still doesn't work.

Google is your friend...you can find anything. That is what I've done.
[Android Apps and Games] sufy1000:
Yeah cheers for that, but i was hoping someone on here could give me an answer as I'm sure they have more knowledge regarding the problem that i have lol
[Android Apps and Games] Fentadroid:
Here you can grab the 2.7.0.0 :)

[Android Apps and Games] sufy1000:
I've tried that version. It worked for like a minute then it stopped working. So it was processing then it said no
[Android Apps and Games] warrencoakley:
Yep same here. Strange. I'll stick with 2.7.10 Just hope they fix the bug of it stop decoding and have to force stop all the time
[Android Apps and Games] sufy1000:
When i install the APK it doesn't install the driver and reboot. How do i make it do that?
[Android Apps and Games] wzlde:
Using AEX ROM on Xiaomi Mi 9. Same behavior as above.

Worth to mention that Legacy version makes call sound (Viber, WhatsApp) choppy and impossible to hear.

So I'm trying to get Viper4Android running on my MTCE Dasaita PX6 headunit running the stock ROM. I've rooted the system via the adb "injection" method (SuperSU). Root access seems to work fine for everything I've tried.

So then I downloaded the Viper4Andrid files (ViPER4Android FX 2.7.1.0.apk) then install

I select OK but found message " Installation failed at the patching system"

Any idea what I'm doing wrong here?

Thank you in advance!
[Android Apps and Games] DiamondJohn:
Have you tried running SELinux Permissive?

Also, getting a logcat of the installation failure would help.
[Android Apps and Games] watchdog69:
I use terminal emulator for select permissive by type

su

setenforce 0

getenforce

then it show permissive alrady but still " Installation failed at patching system"

I uninstall viper4 then install again result it same " Installation failed at patching system"

Please recommend I don't know where is the logcat file has save?
[Android Apps and Games] warrencoakley:
What why is it typed into terminal please?
[Android Apps and Games] jamesta:
I installed V4A with Magisk, I absolutely love it! I love you guys? lol. It says I have version 2.7 installed but using Driver version 2.5.0.4

Do I have the most updated version? I'm on Motorola One Zoom - Android Pie

Any feedback is appreciated!

Thanks
[Android Apps and Games] Soumy1234:
There is no 2.7.1.0 drivers. Viper development was originally stopped at 2.5.0.5. Don't worry, it's supposed to be like this.

[Android Apps and Games] lollilol:
Thanks for your help, but since then I gave up installing v4a.

Yesterday i tried it again (on a clean setup, installed a few days ago) and everything went very well. It's all working now, I just had to install the app, give root (with magisk) and reboot.
[Android Apps and Games] Anova's Origin:
Viper 2.7.1.0 is working well on my OnePlus 7 Pro running stable OOS 10. I updated from stable OOS Pie without wiping (and rather foolishly without disabling Magisk modules) and everything seemed to work at first. However, Viper seemed to break Bluetooth audio, as no sound was playing at all through Bluetooth headphones. Deleting and re-installing all of my Magisk modules (including Viper 2.7.1.0) resolved the issue without the need for a factory reset.

Viper is currently fully processing audio (local playback, YouTube, and Spotify) going to: the on-board speakers, passive wired headsets, USB DAC wired headsets, Bluetooth speakers/headphones, and Android Auto. Viper appears to be more reliable after the Audio Modification Library Magisk module was installed. The Audio Compatability Patch Magisk module did not appear to affect anything, so I ended up disabling it without apparent issue.
[Android Apps and Games] sufy1000:
This is such a major issue with viper now that sometimes it just doesn't process. Had so many problems with it.

They've definitely changed something.
[Android Apps and Games] killoid:
is there any ota survival zip available for this? everytime i flash my rom, i have to reinstall the driver. it is quite bothersome.
[Android Apps and Games] jamesta:
Everything working fine except YouTube through phone speakers, I have to manually switch the master limiter notch off to hear YouTube audio. Should I reinstall Viper and try again?

I can't live without this app lol
[Android Apps and Games] mrrocketdog:
ok , need a little help here.

moto e4 plus. rooted with superSU. Slimrom 7.1.2. selinux permissive.

download and install VIPER4Android v.2.7. click on app. opens with message "no driver found would you like to install now .......". click on "OK". starts to download , gets maybe a ⅓ of the way and app force closes everytime.

so ; went to twrp and flashed "VIPERAudio+Super+Quality+NEON+Driver+3.0+Universal.zip" rebooted and got same results. next ; went to twrp and flashed "VIPER4Android+2.4.0.1+NEON+Driver+Universal.zip" with same results.

is this a magisk only app? should selinux be enforcing? am i missing the boat altogether?

any ideas/help/links/suggestions/shot-in-the-dark?

thank you all. :cowboy:
[Android Apps and Games] Gordietm:
For reason v2.7.0.0 works perfectly on my OnePlus 7 pro. When I try and update the magisk module to v2.7.10, I lose the driver.
[Android Apps and Games] DiamondJohn:
A logcat of the failure during install should help.

As for SELinux, enforcing will increase your chances of an issue. I personally run enforcing because viper works with enforcing and its generally more secure.

Hi,

first thank you for this great port of v4a....it is really working and it is much better than install v4a, then busybox, then selinux swich and then install driver :)

But one thing i have missing so i must go back to original v4a :(

I need to load and save headphones profiles. I have now profiles for 4 different headphones and i need to swich profile quickly :(

This is only one that is missing for me....i have no problem with purple/white menu :D

Why do you think you can't do that?
[Android Apps and Games] ShawnRose:
audioserver testing

So, as is regularly commented here sometimes audioserver starts up without loading v4a for some reason. The solution is to kill it: but I found there's actually a way (That probably requires root) to detect if it's loaded.

If audioserver didn't load v4a for some reason, it won't show it in the maps for the process. So, find the pid, check to see if it has libv4a_fx.so in maps, and if it doesn't, kill the process.

audioserver="$(pidof audioserver)"
( grep -q "libv4a_fx.so" /proc/"$audioserver"/maps ) || kill "$audioserver"

There's an example. I don't know if that works everywhere: maybe some versions of android restrict maps usage, or even procfs access even with root: but it might be a good idea for the app to at least try detecting it. Failing that, a simple "if it isn't loaded, try killing audioserver and waiting a second before testing again and then if needed showing the error message" would be helpful.

Hello guys. I tried searching on the thread and on Google but couldn't find any info on rootless. I always used V4A on my rooted phones, but since I got this Motorola One, I have been avoiding rooting it because of the Android one program.

My question is pretty dumb, but I just want to know how is V4A rootless is coming along and see if there's anything I can do to help (depending on the status, maybe testing it in alpha, beta, etc.).

[Android Apps and Games] NM99:
Tried flashing it via Minimal ADB and Fastboot, but had this happen:

error: cannot determine image filename for 'v4afx-rootless_08.18.2019.zip'

I imagine this is because either the OEM or the bootloader is locked... Not really sure if unlocking one of both of them will stop me from getting the android one updates for my motorola. Guess I have some deciding to do.
[Android Apps and Games] CornholioGSM:
....after one day of testing.

THANK YOU AGAIN FOR THIS KOTLIN VERSION OF V4A.

Hi --

I've been reading a lot of the posts on this thread and tried a bunch of things and no luck.

I'm on a Google Pixel, Stock w/ Android 10. Rooted w/ Magisk (full)

V4A installs fine, but no matter how many times I try to install the driver and reboot, I'm always asked to reboot to install the driver.

I followed some of the suggestions on the thread and tried using ACP - Audio Compatibility Patch, and with that, the driver does install, but I get No for both Enabled and Processing. I also tried the method of using AMP and also tried using 2.7.0.0--all, no luck.

Any suggestions?

When it installed and showed "Enabled: No" did you flip the Master Limiter switch to enable Viper?

Only then it will indicate if it's processing correctly.

I tried that too and got it to work in that the driver is installed, but when I play music, both the Enabled and Processing say "No".

Yup, flipped the Master Limiter switch, still No's for both (see attached).

Just wanted to make sure since I forget that occasionally. I guess at this point you have disabled or de-installed the Audio Media Library? If so try to activate/reinstall AML. That normally fixed it for me during q-beta/10 on the p3xl.

Driver not Installing

Hey just updated my Poco F1 to MIUI 10.3.8 yesterday. Today when I opened the Viper app to change some settings, it says that the driver is not installed. So I press the install option, the phone reboots.....and the driver is still not installed. I tried uninstalling and reinstalling the app. Tried to do it on Magisk. Nothing happened. Also went to the root folder and renamed the audio_effects.conf file and tried installing the viper app again. Nothing works

MIUI 10.3.8. Anyone else facing this problem ?

Also just found out that after renaming the audio_effects file, I can't rename it back ?? Used Solid Explorer and FX Root explorer. None of them can rename the file back ?? I renamed the file from "audio_effects.conf" to "audio_effects.conf.bak". But can't rename it back now
