Ya, I don't know what it'd be at this point. Only thing I can think of is to check all audio effect files and make sure there's v4a entries in them. Maybe your device has some weird one the zip didn't patch
[Android Apps and Games] NotATreoFan:
I've seen some people post in this thread with a OP7P, so it does work, but they were all rooted.

Thanks for all your help with this. I'll have to decide if I want to go through with Magisk and hiding root from my apps.
[Android Apps and Games] sjamie:
In case it helps anyone, I followed these steps from my good friend [MENTION=5893314]shadowstep[/MENTION] to get Viper 2.7.1.0 working on my rooted OP5:

1. Install ACP from Magisk Repo (skip patching the audio policy and only remove the notification_helper effect.)

2. Reboot

3. Install the V4A 2.7.1.0 apk from XDA Labs and install drivers once prompted by the app after you open it for the first time

4. It will automatically reboot

5. Install AML from Magisk Repo

6. Reboot and profit!

Viper should now process audio consistently even after reboots and without needing to open/close the app.

**Note 1: Make sure you have no traces of any other V4A installation or drivers present; otherwise, the steps above may not work for you.

**Note 2: Dirac is disabled on my phone so I don't know if it would conflict with Viper. If the steps above do not work for you, try disabling/freezing/debloating Dirac.

Hey I have the Jabra too, wondering what settings, irs etc u use cus I've been trying but can't seem to find a good one. Lots of people suggested dbx160sl but I find that even tho it's pretty good it kinda feels like there's slow pass filter making the sound feel trapped where lots of music kicks in if u get what I mean. Thanks!

Here's one for the Jabra elite 65T my brother got them and I was trying to make a decent preset for them.

[Android Apps and Games] Listy2021:
I can't get Viper to work on my Mi Mix 3 (Arrow OS GSI Pie ROM) for love nor money. Followed every guide and tip there is on XDA and elsewhere and it just mutes the phone when the Master Switch is activated in the app! (and I mean mutes it... no alarm sounds, nothing)

Music is shown to be playing and Viper says it's compatible and enabled but yeah no sound at all *sigh*
[Android Apps and Games] NotATreoFan:
Thanks for these steps. I decided to go with rooting after my OP7P kept fighting the rootless method. I was able to get the driver installed and processing with these steps, but I did notice a few things.

First was trying to find the Magisk modules. Had to clear/refresh the cache probably 15 times to get the two I needed to show up. Second was after using my Galaxy Buds over BT for around 30 minutes, the driver switched to Abnormal when I tried playing a YouTube video through the speakers. Disabling and enabling the various options did not help. Rebooted and tried again through BT, and it worked correctly on the same video.

I did not disable Dirac, as I'm not really sure what that is and reading out it online didn't see an easy to do so, nor what other effects it may have.
[Android Apps and Games] shadowstep:
ACP = Audio Compatibility Patch = This fixes music and streaming apps (Spotify, Pandora, etc) that aren't processing audio effects for various equalizer applications through the modification of audio policy. XDA thread here for more information.

AML = Audio Modification Library = This mod allows you to use multiple audio mods at once with magisk. XDA thread here for more information.

For me personally, the rootless method did install the drivers but the driver status was abormal, so it didn't work all (I gave it a shot even though I'm rooted). Then I started experimenting and eventually found the steps that worked for me 100% of the times (the same ones outlined by [MENTION=4204995]sjamie[/MENTION], which are the ones I shared with him).

DIRAC is an audio solution in-built into OOS, and hence it might conflict with V4A. Removing it made no difference to the audio quality for me plus doing that ensured it wasn't conflicting with V4A in any way, since it also affects the audio stream. I highly recommend you remove both /system/system/app/DiracManager and /system/system/priv-app/DiracAudioControlService and then give the steps a shot. Good luck! :good:
[Android Apps and Games] NotATreoFan:
Thanks, I'll give it a shot. I am rooted now, and after a reboot it began working again, so I'm more curious is these apps could have caused the issues when using the speaker output. I'll freeze them with Titanium and report back.

-Edit-

I don't have either of those apps on my OP7P. Checked with Titanium and Solid Explorer.

-Edit 2-

After another reboot, V4A is processing for both speakers and BT, allowing me to switch between them also. Next test is Android Auto when I get to my car.
[Android Apps and Games] Joe199799:
Hey stupid question I'm guessing you need TWRP to install the rootless version still? My brother wanted to use viper but he can't root his Sprint S8 (unless there's a method I'm unaware of) but I'm guessing at the bare minimum you need TWRP. Still pretty cool there's a unrooted option thanks.
[Android Apps and Games] jdpal111:
[MENTION=6037748]Zackptg5[/MENTION] any thoughts on this? Can I get you more info to help troubleshoot? Thank you!
[Android Apps and Games] DiamondJohn:
you don't need TWRP, but you will need root via Magisk.
[Android Apps and Games] Joe199799:
No I meant the rootless version I should said that thank you though
[Android Apps and Games] NotATreoFan:
I'm able to use AA with V4A and control it with the BT options.

How to uninstall driver?
[Android Apps and Games] fossean:
I had the "driver not installed" problem with viper 2.7.1.0. and successfully fixed it with this command in terminal

But after a few weeks of Viper working perfectly, the "no driver" problem recurred. This time when I ran the above command in terminal emulator I got the error "-c: not found". If I remove the -c option and instead run the commands below, it gives no error and viper immediately begins working correctly.

Can anyone who understands this please give a hint what's happening here. I think I understand that the -c option passes the command to the shell, but I don't know why we need to do that. And I don't understand why it once worked but now doesn't :(

Running NitrogenOS Pie 20190806 on a OP3T; rooted with latest Magisk and busybox installed.

Incidentally, I found a great Magisk module called 'Daily Job Scheduler' that allows commands to be run automatically at boot or scheduled to run daily at any time. Works perfectly.
[Android Apps and Games] marcdw:
V4A does. I don't use Magisk on any of my ROMs. A few use V4A 2.7.x just fine. As far as the extras, like ACP, AML, and the like, I too would like to know if any helper tools work on other roots other than Magisk (SuperSU, Lineage su).

[MENTION=320479]NotATreoFan[/MENTION], I forgot about this, it may be the problem for you. This is built into the app but requires root I believe

Hope someone can help

Trying to set this up on an android head unit and although I have root the installation of the driver fails, I believe the app cannot access system

So can I install the driver manually? Manually copy files over to the system?
[Android Apps and Games] DiamondJohn:
the "-c" at the start of the line makes no sense to be there. The first word in a command shell is the command. There is no "-c" command. It is formatted as a parameter/option (with the "-" sign in front) which would be placed after the command, which is "killall" in this case.And further, I do not think the killall command even has a "c" option/parameter, so would not work or may even be complained about if placed after the command.

Nice UI and finally the service isn't stopping after the phone is on for a longer time.

Overall good, but I am missing a few features: Adjustable gain (usually had +6dB for bluetooth devices), Channel pan and the ability to save profiles.
[Android Apps and Games] fossean:
Thanks for the clarification. I think there could be quite a few people running the incorrect command 'su -c killall -q audioserver' as it has been quoted several times, earlier in the thread.

To reiterate, running it as below fixes driver error immediately

Will the ACP mod help to stop random pops and other impurities I hear with streaming apps?

I use more high end headphones and good headphone amps. It feels when I listen through the headphone amp, I'll hear random crackles and pops.

I'm able to adjust gain and save profiles. For profiles, make all the adjustments you want, then tap the BT icon, then New Preset. Enter a name and the adjustments you made will be saved under that name.

Have tried Audio Compability Patch, etc. Still no fruits

Does anyone have anyway to make this work?
[Android Apps and Games] marcdw:
That command is correct when entered as a single line as written. But in your previous post you ran su first to open a root shell then tried to issue the killall command starting with -c, which ofc wasn't necessary.

So all is fine actually. You just initially didn't issue the command as written.

To wit, less interaction with the single line.

su -c commands [ENTER] done.

vs

su [ENTER]
commands [ENTER]
exit [ENTER]

[Android Apps and Games] DiamondJohn:
===edit - as above by [MENTION=6046143]marcdw[/MENTION] that i missed reading before posting ;)===

Wait a sec! you had su followed by a line feed.

The correct line

su -c killall -q audioserver

which is very different to your incorrect lines

su
-c killall -q audioserver

The -c is a command parameter to the command su, as in the correct line, NOT the start of the killall command as you had it.
[Android Apps and Games] fossean:
Oh, now I get it. I've actually learned something here today. Much appreciated!
[Android Apps and Games] Peter.1997:
Thanks for that answer, the profile function does indeed work like that, didn't know it. For the gain though, there isn't an option to adjust it on my phone, like it was in the old V4A versions. I have the newest version from Magisk repository (installed through Magisk Manager) and the last option point is AnalogX. My current workaround is setting all EQ bands up to +6dB.

I also don't have the option to set a dark theme like it is shown in the 3rd screenshot of the first post in this thread.
