QUOTE=aryanpv;82872831]First, uninstall any viper you have also make sure you completely uninstall audio modification library if you have it installed, not disable, uninstall it and reboot after uninstalling what I've listed.

After you're all booted back up, install viper from labs (link in this thread)(Also, forget about compatibility mode, don't use it) now open viper but do NOT install the driver yet, just open the application then go to magisk and install audio modification library but dont let magisk reboot the phone after it installs. Once installation completed, go back to viper and install the driver and let it reboot. Once booted, go straight to magisk and DISABLE audio modification library (uncheck the box next to it if you dont get what I mean) don't uninstall it. After disabling AML head back to viper and install the driver again. Now once rebooted is the moment of truth, if you open viper and its installed you're obviously done but if it's not installed you have to take this next step: don't install the driver just yet, go to magisk and re-enable AML then back to viper and install the driver.

I hope this helps[/QUOTE [MENTION=6530865]Lughnasadh[/MENTION]

I've actually tried both of your methods before with no success. But I'll probably give it another shot. Does anybody know if the music FX 1.0 that comes with Pixel phones has anything to do with it failing? I doubt it cuz I don't think that happened in the past but just curious.

I tried this method on my 3xl as well, didn't work
[Android Apps and Games] Lughnasadh:
Music FX doesn't affect the driver installation. However, it can affect V4A's processing so it should be disabled.

[Android Apps and Games] Vinayakn73:
Hey guys sorry for this but can I ask if the updated version has master gate with audio channel pan and audio gain support like legacy version, cause 2 or 3 month back when I had checked it did not had these options. I hear less from one ear so it helps me a lot (channel pan option). Sorry for bad English
[Android Apps and Games] surajloharia:
Yes it do have both
[Android Apps and Games] PoochyX:
I believe so

([emoji88]Havoc GSI[emoji88])
[Android Apps and Games] Vinayakn73:
Thank you so much.
[Android Apps and Games] brandontowey:
I tried this method, too, with no luck. It worked previously but ??. Running BlissROM and got a reply on the thread with an attached apk and instructions to reboot three times (I did it by installing the driver three times, kinda vague instructions).

I can't vouch for the apk so removed the attachment though it worked for me. Waiting on a response as to where the apk is from but might be worth trying with the official one.
[Android Apps and Games] Lughnasadh:
Thanks but I don't have a problem installing V4A. It installs normally for me. Think you meant this post for someone else :confused:
[Android Apps and Games] brandontowey:
Oops, wrong person. Thanks.

I was having the same issue on BlissROM. Someone posted in the thread to try a particular apk they attached and reboot three times. I won't attach the apk because I can't vouch for it but I tried it and installing the driver three times and rebooting worked ??*♂️. Might be worth a shot with the official app. AML and ACL and the previous method used to work but didn't this time.
[Android Apps and Games] Shaftamle:
Thanks for the reply. I am starting to think this is just a random luck type thing. I've done so much reading about this and there are so many people that have had no problems and so many people that cannot get it to work. I am far from a coder, developer or Android genius. But I have never came across a mod that I was not able to eventually get to work on my phone except for this. I guess it's just one of those things but like I said I appreciate the response. I'm just clueless at this point. It would be great to get some feedback or direction from the actual developer but Maybe I'll have to email him.
[Android Apps and Games] CamoGeko:
Android has always been about trial and error, I should know have been using it for over a decade.

It's usually dependant on ROM compatibility with the mod itself. When it doesn't work its likely not supposed to due to some specific commits within the ROM.

Sent from my PH-1 using Thebear Blue XDA Labs
[Android Apps and Games] brandontowey:
Yeah, it can be depending on your ROM, apps, etc. The three reboot thing worked first time for me though. I uninstalled everything, rebooted, installed viper and did three driver installs and boom, it's working.
[Android Apps and Games] Caleeeeeeb:
I was actually the one and at this point love to try that method if you have a link to the instructions or can you elaborate on the reboot three times line?
[Android Apps and Games] brandontowey:
1. Uninstall any viper or audio modules you have

2. Reboot

3. Install viper and the driver, let it reboot

4. Open viper again and it should ask to install the driver again

5. After reboot, do it one more time

6. Disable battery optimization after you got confirmation that the driver is working

I've attached the apk given to me, it's an older Dewitt viper that the person who gave it to me said never has issues.
[Android Apps and Games] PoochyX:
Viper functions just fine while battery optimized

([emoji88]Havoc GSI[emoji88])
[Android Apps and Games] brandontowey:
Good to know. Read that somewhere and figured why not?
[Android Apps and Games] Arcide:
I wanted to try your solution, but I get a bootloop when rebooting after V4A install.

Anyway to repeat my question if anyone who sees this has an idea.
[Android Apps and Games] brandontowey:
Have your tried different convolvers? I get weird issues with certain ones and only have 2-3 that I use from hundreds I've downloaded.
[Android Apps and Games] Arcide:
I have tried a lot of them, and I think they all behave the same. I have found one that is just perfect, so I would hate to have to change lol

Edit: Oof, I did find out that there are some way worse than others. Like with some convolvers you can only hear half of the sound (the bell-like sound when moving the media loudness slider in phone sound settings) and then it clicks 5-6 times for the remaining part.
[Android Apps and Games] uudruid74:
What is different about the "super quality" driver from the standard?

Is there any 24bit/96Khz version? I'm really looking for this for an external DAC.

And a quick tip. If it stops processing, turn off master limit switch, flip the "attach session" switch on and then back off again, then turn on maater limit switch. If it fails, try it again. Always works on the 1st or second try.

Turn off the Spectrum Extension and see if that helps.

I normally only use the Joe Meeks convolver. Its my main reason to use Viper!
[Android Apps and Games] Ms0206:
Oops, was in the wrong thread, sorry.

However, Viper works fine...unfortunately it still looses its "channel" here and there (even though I have "audio modification lib" installed by a manual somewhere here).

A simple reboot helps, but I still wonder why
[Android Apps and Games] brandontowey:
I've never used the spectrum extension but I'll definitely try the Joe Meeks convolver. Is it a general one? I mostly listen to R&B and rap.
[Android Apps and Games] uudruid74:
Yea. I forget where I found it, but if you have trouble finding it, let me know
[Android Apps and Games] halfbytecode:
I installed magisk version 2.7.1.6 on AOSiP 10, based on Android 10, on OnePlus 5T.

However, the effects do not apply for some apps, like in the Facebook app.

Enabling "attach audio effects" makes audio stop working in a lot of apps. I get no sound on a lot of apps.

I even tried installing Audio Compatibility Patch, as suggested in the second post, but it does not make it work either. It simply makes the effects work in the apps, where they did not work without ACP, and vice versa. Even after enabling "attach audio effects" I get no sound in a lot of the apps.

This all used to work fine on Android 9 with Viper legacy and ACP.

How do I make it work on Android 10 now?
[Android Apps and Games] brandontowey:
Got it and oooo it's smooth. No drastic changes but it makes everything better. Also helped a lot with the overemphasized highs I was having so I was able to bring back the mids I lowered. I attached it with a bunch of others that I find if anyone needs it.
[Android Apps and Games] bradical711:
Just tried the convolver and omfg it changed everything. Smooth as butter no kidding!! Thank you!!!! 10/10 reccomend to anyone! Insane convolver!!

Set Eq and master to max but still too quiet :(

Only me with the problem?

Im using lineageos 17.1
[Android Apps and Games] MarkusOSx:
you need to reinstall the drivers ;)
[Android Apps and Games] Wishmasterflo:
Yes I guess via Bluetooth tge sound quality is different. Perhaps try to use some other Convolver for bluetooth.

Is it possible to get 96khz over LDAC to work? Currently V4A works only with 48khz, and I didn't find any way to make it work with 96khz

Also, question for developers: is it possible to get v4a drivers work without root( i mean create an app that would work like wavelet)? It would be great as viper is the only reason for me to root.
[Android Apps and Games] vskr1:
You can try to set SELinux mode to Permissive. For example, using this app.
[Android Apps and Games] usaradark:
Is this supposed to work on ringtones and system sounds too? Whenever I get a call my settings revert while my ringtone plays, and since my DAC is pretty powerful, it becomes very loud since I use V4A to lower the overall volume.

Using a ZTE Axon 7 on Android 9.0 for reference
[Android Apps and Games] bombadier:
Unless there is something special about your device then no, viper should not affect system wide sounds as far as I know, custom kernels can boost the volumes though

My camera doesn't work after I installed viper. Could anyone help me? Device Mi 9 SE.
[Android Apps and Games] mily-manson:
finally i do root my head unit and install v4a,

but i have some issue,

1- its only speaker mode work with less option and my car head unit need full option, i read in this forum the lock feature able with 2.5 version and remove in last version, is it possible return back?

2- v4a works just with default music player, and wont work with like poweramp or chrome play music ..., can its work all around device sound (like online radio or app)?
[Android Apps and Games] Shaftamle:
Well this literally might be one of the best and most useful responses I've seen in a while. So I'm wondering since you seem to be pretty well versed in this whole thing. Does the new 2.7 V4A app work with majest 20.4 or does it have to be 20.3? Cuz I can't get this thing to work for the life of me
[Android Apps and Games] MajinBoo17:

is it work on poweramp or other application sound?

because i remove v4a 2.7 and download 2.5 from v4a website and lock mod is work now, but its not process on poweramp.! (even i disable DVC and enable MusicFX and v4a no process)
[Android Apps and Games] ManuelR9:
Hello guy! I am with my OP3T and android 9 stock 9.0.6. I am root with magisk 20.4 and when I install the V4A it won't let me use it, I have the problem mentioned in the post. I have SOLID PRO installed but I don't see the path /magisk/v4a/system/etc/audio_effects.conf to be able to copy and paste the file, in which folder is it?

And it doesn't let me copy the APK file to my mobile, either way, I don't know what happens.

Thanks crack!
[Android Apps and Games] MajinBoo17:
I recommend to use v.2.3 over 2.5 ,since v2.5 has a bug with the clarity feature ,which not always works.

disable MusicFX and poweramp build in Equalizer. Or try ViPER in compatible mode. However the best and easiest solution is to use pulsar music player it's simple lightweight,quick overview, has no unnecessary features and works with ViPER perfectly

Hi there! is this Viper4Android working in Xiaomi Mi 10 ? i would like to know in order to install it . thanks!!
[Android Apps and Games] mily-manson:
SO, you mean

2.3

better than 2.4 either 2.7, (No 2.7, No 24, Just 2.3?)
[Android Apps and Games] MajinBoo17:
Actually there's no big difference between the versions. The big difference is whether you use V4A or not.The quality between the versions is a small thing and more a placebo than a difference

I'm not sure what you mean by copying files to specific folders. I've never heard of that. However when I was on 9.0 all I ever had to do was install the app and then the drivers. Instead of using 2.7.1.6, go to majest modules and look for viper FX. That's the older one that was built by the original developers which I believe still works on 9.0 and seems to be a much more straightforward.

@Team_DeWitt

Look man, I know it's not your job to troubleshoot everything. I know there's a thousand phones out there and a hundred different Android versions and you have your own life. But I'm asking if you could possibly put your two cents in on this whole issue that so many people seem to be having.

I posted a screenshot a few days back but Viper consistently comes back saying status: abnormal

Audio format: unsupported.

I'm on pixel 3xl stock 10.0. June update. Majest 20.4 and I have tried absolutely everything under the sun. If there's any logs that I could send you or any way that we could try to resolve this that would be great. Because as much as I absolutely love this app, beating my face into the wall everyday trying to figure out what's wrong is just not worth it. I'm pretty sure there would be hundreds if not thousands of other people that would appreciate your input since you are the new developer. But this is a widely known and reported issue that seems to be unsolved for the most part.

Thanks

I have been running fine on lineageos17.1, just follow the android 10 guides in this thread itself posted by users, try disabling any audio effects apps in your phone, prebuilt or otherwise or just switch to lineageos and try the same
[Android Apps and Games] mily-manson:
actually 2.3 not work on my unit because i install driver 2.5.0.4 and i think it not work with v4a 2.3, so i install 2.5 and its work like charm and i can lock mode in headset.

but i like va4 2.7 new UI how can i tell a4a developer to add lock mode in this version?

And a question ?

in the first post say " Car mode / head unit detection for better support "

what is that?

Amazing module, but sadly i couldn't get it to work with my bt headset... Every other option works and it does improve sound a lot, esp with wired connection (same headset that i use with bt). But i'm using bt 90% of the time... So just ended up uninstalling it.

EDIT: Reinstalled everything again and disabled aptx HD audio thing in bt headset settings and now it works. Will test it from now on and report back in a few days.

Only works when enabling attach audio effects?

Since switching from MIUI 12 to AOSP Extended (Android 10) viper only works when enabling "Attach audio effects" in settings. (Without it switched on it says not processing. Sounds fine but with that switch enabled other apps like Instagram don't play sound at all. I already tried audio compatibility module for magisk, doesn't do anything for me. Have had this problem on various other AOSP-based ROMs before so I can't be the only one with this issue.

I'm using Xiaomi Mi Max 3 with magisk rooted AOSPExtended.
[Android Apps and Games] eXtremeDevil:
Hi, after a long time without using it, I've started playing with Poweramp again. Also, I've always used Viper. Right now I have latest version on Magisk. As Iong as I can remember, PA has its own audio engine, DVC, and if enabled, once music started Viper would be disabled. That's how it worked back in the days I used PA. But now, it seems that both engines are running at the same time. Is it normal behaviour? Because I don't know if maybe DVC is malfunctioning and not actually applying anything. And if it is, is there a way to disable Viper for Poweramp only? I would like to use only PA audio engine by now. And no, I don't have the compatibility mode enabled in Viper.

Thanks in advance.

Why do you think it would work? You have 4 different settings pages in V4A: headset, speakers, bluetooth and usb. Chromecast doesn't fit in either of those.

[Android Apps and Games] DiamondJohn:
If it is a true systemless Magisk implentation, then removing the magisk module should remove all the drivers, the app and the configuration changes.
[Android Apps and Games] halloarno:
If casting from your Android phone in settings, then viper is processing as speakers.

If you remote Google cast with the help of a compatible app, then there is nothing processing in your phone so neither viper.
[Android Apps and Games] Shaftamle:
Definitely not going to work with Chromecast. Your phone just acts as a remote. Chromecast works off your internet which is why you can start a video and then leave the state and the video will still keep playing. I guarantee this. It's the exact same thing as a Sonos speaker. The only way viper will work with a Sonos speaker is if you use the auxiliary port. Because Sonos works off your internet you're basically using your phone as a remote control for it
[Android Apps and Games] halloarno:
Well, your partly right. Chromecast acts the way you say, but also like this. I garanty it works for several years now. Play audio (or video) on your phone, goto settings, find casting (for me: Bluetooth&connection/casting), select your chromecast.

Now your audio is captured from your device, including equalizereffects like viper and processed through cast.

Viper detects this as normal speaker sound. With viper legacy you can pin the soundeffects, to p.e. Bluetooth, so you have more options. Unfortunately that option isn't available on viper from team the Wit.

Im new to v4a, but on v4a notification system it says processing all the time even no playback on the speaker. Is this normal?
