Improved Audio on Oreo Custom ROMs (Ainur Sauron)

I am part of the team for Ainur Sauron, and I am here to present improved audio on the Le Max 2. Sauron has a userconfig which can be adjusted. Download the latest from there and place the attached file at /sdcard before installing. Make sure to remove the '.txt' at the end of the file too! Enjoy :victory:
Impedance is currently set to 16Ω which can be changed to whatever you desire. To set edit the attached sauron_useroptions file and change qc.impedance to whatever your headphones impedance is in Ohms multiplied by 1000 (eg. for 22Ω it would be 22000).
Tested by @I_Raptor_I on his x2, if it doesn't work just send me a log
EDIT: Attached the file

I did not know that anyone else was using Ainur Sauron on LeX2 It really improves the audio quality significantly on Oreo!
Quick question - why does it say "Axon 7" during installation procedure?

Hello GaetanoS.89, first things first uninstall the MK II Magisk module. Now place the given text file in /sdcard folder, then go and flash that module again, it should state that it has detected the user options text file and that's it.

I have not installed magisk n the smartphone.
Can you tell me how I can uninstall it?
Do I need magisk to let work this audio mod?
Thanks

Magisk isn't needed as it'll install with any configuration. All you need to do is placed the attched file at /sdcard (called Internal Storage) and rename it to sauron_useroptions (remove the .txt. at the end).

Did it, and after What I have to do?

@Lazerlord: I tried your mod today by described method.
I copied "sauron_useroptions" into sdcard folder by TWRP file explorer.
Afterwards I flashed latest zip (17.03.) using TWRP. Everything was fine with it during this.
Wiped chache and dalvik and rebooted without any problems.
Result: No ringtone anymore, no message sound, but media sound works fine and was adjustable, no app or menue occoured in regard to your mod. I did not check more.
I could succesfully remove your mod by described method (flash again same file from TWRP)
After removal everything was fine as before :good:

Ah, well could you follow these instructions on the main thread which say "help to extend features". It'll help us fix those issues. :good:
How was the media sound though? Did it sound better according to you?

I removed the "sauron_useroptions" from sdcard folder (as it was described in the file itself, that UO is not mandatory) and reflashed the zip-file again.
With this way everything works !
Will read a little bit the instructions now...
Generaly I have to say I am using Leeco CDLA as headphones atm which are extraordinary by themselves.
So maybe I will use adapter for 3,5mm jack whithin next days and try some user options. Leeco Loadspeaker judgement is difficult imho.
Also new AEX is very good ROM in regard to speaker sound I have to say.

On Oreo 8.1.0. PixelRevenge 15.1 works very well in music playback. He gave me a strange problem. I removed the system camera that I can not install anymore. I had to put another one. I have not tried calls and notifications yet
edit:- Notifications and ringtones ok. In-call audio worsened, the voice is less clear. In speakerphone there is a loud hiss that makes the speakerphone unusable

We're working on a fix for the mixer_paths that'll correct notifications, ringtones, and other audio. I'm happy that you're enjoying music playback. However, the system camera app problem is nothing to do with Sauron it's probably a ROM issue, or possibly even a Magisk issue.

I've installed this Mod by using Magisk 16.0 (v5.6.4) on RR 6.0(22-03-18).
Before I did this I placed the file sauron_useroptions to /sdcard folder.
During the installation Magisk showed that the useroption file was found and used for the installation.
In Poweramp I get the message that there is a problem with app native libraries (libampffmpeg.so).
I don't know whether the error message has something to do with that, but the volume control in Poweramp after flashing this modul is faulty.
Just when the volume is set the half I can hear anything. The volume control steps seems to be broken, but just in Poweramp.(After uninstalling, the issue is gone, but the error message is still sthere)
In other Apps the volume control is normal.
Since I use RR 6.0(8.1) instead of RR 5.8.5(7.1.2) the speaker sounds cheap tinny - Ainur Sauron didn't help to solve this issue. I removed AudioFX, can this be the reason?
It's difficult to describe the issue "cheap tinny", but I think the audio drivers have problems to divorce the difference frequences.
On RR 5.85. the speaker was more "smooth" and the frequences were divorced much better.
Sorry for my bad english and the critic. I think I'm an individual case and other people don't have the problems which I have, but in my case, the Mod seems not to improve the audio quality.

I've heard from @I_Raptor_I that RR already has a loss in audio quality. I advise the use of another ROM and if the tinnyness persists use the attached Sauron zip.
The Poweramp problem is probably due to DVC (Direct Volume Control) in their FAQ they state it may cause issues with 24-bit or HQ audio. The native libraries issue is not related to Ainur as it doesn't touch that file.
About the audio. ROM (which Sauron edits) isn't the only thing that contributes. the HAL and kernel do too, so RR's bad audio may not be able to be fixed or corrected by Ainur but we'll take a look into it.

Ok guys, @LazerL0rd is kindly developing a very nice Oreo kernel for our Le Max 2 improving the speeds dramatically and most importantly audio, he has already optimized our Qualcomm DSP, expect a very nice audio experience on Oreo from now on so stay tuned and make sure to thank LazerL0rd for his hard work, he doesn't even have a Le Max 2 and yet he is spending hours making this kernel for us

Magisk viper?
I have installed viper on RR Oreo via magisk and audio quality is now on point with how it worked through flashing viper and Dolby Atmos on the nugart RR via twrp. There are a couple of things to consider though, viper must be activated before listening to music through your app, viper does not work over Bluetooth by default in viper meaning you must go to viper settings and set mode to compatibility from normal and then viper will work over Bluetooth. The last thing, and I can't remember if this was true on nugart but viper seams to only work with music that you have downloaded to your device and will not work with streaming music from the web.

The Same one Which is Present in the Magisk ( Search Audio Modification Library 1.8.1 in Magisk)

Can you please advise if the sound quality of the headphone jack is any good? I got the Axon 7 so really want to know the quality compared to the Axon

Viper and dolby sound really bad on poco for some reason. Too much static noise and random squeaks which hamper the hearing experience. Going to try Ainur and see how it sounds.

I've had LG G3 with Quad DAC or whatever, and Poco sounds the same, if not even better (can go volume to 11, for sure) compared with it.
Sound is clear, good bass on headphones, etc.
It somewhat depends on the music player , good quality headphones, and eq settings, but with all turned off, completely satisfying.

Compared to my LG v20(quad dac) when comes to soundquality i dont miss my LG much its only better by maybe a very small margin. Ofcourse the LG dac has much more volume level because it can drive 600ohm headphones
With other words the pocophone internal audiochip is pretty great actually which was a surprise for me
Im driving my IEMS from audeze with ease (isine 20)

Guide to Viper on 4 XL (Easy)

Here are the steps to install viper with a Pixel 4 XL:
1. In magisk go to downloads, install the audio compatibility patch 1.7 3. Choose volume up for requested settings, although USB can be set as preferred.
2. Reboot
3. Install XDA Labs Viper. Do not open.
4. In magisk go to downloads, install the Audio Modification Library v2 4. Do not reboot.
5. Open Viper, let it install driver and it will reboot.
6. Go to app info for viper, disable battery optimization.
That’s it. Enjoy the audio bliss.

Thanks for this.
Questions;
- For step 1 in your OP (install the audio compatibility patch). Just want to make sure I'm using the correct patch. What version number? At the time of writing I see V1.7.3. Is that what you used?
Also, during installation of that patch, there are a number of vol up/down options that need to be chosen. What did you choose for;
- Do you want to skip audio_policy patching? (Original acp before became 3in1 module) Vol+ = yes, Vol- = no
- Would you like to skip notification_helper remover? Vol+ = yes, Vol- = no
- Would you like to skip usb policy patching for usb devs? Vol+ = yes, Vol- = no
- Use lib workaround? Only choose yes if you're having issues. Vol+ = yes, Vol- = no (recommended)
- For step 4 (install the Audio Modification Library). What is the version number? At the time of writing I see V2.4. Is that what you used?

Thanks. Good questions.
It was 1.7.3 of the compatibility patch.
Volume up to all the options.
Version 2.4 is also correct.
I'll amend the guide to contain this information.

I didn't do the audio compatibility patch part. You reckon that could cause issues? If I were to reinstall, would uninstalling everything and starting from scratch be okay? So far viper does work.

Or you can grab V4A version 2.7, install it, do the drivers 3 or 4 times for it to actually take, profit. I have it working on my phone without any other steps.

As I understand it the audio compatibility patch enabled viper on USB output like for Android auto.
It also makes it so you don't have to reboot repeatedly to get the driver to stick (according to others).

Hello, I followed all the steps and I still getting "No audio driver found"

I got this

Hey OP, do you use Google maps navigation by any chance?
I have Viper working on my 4 XL as well, and with the installation of Audio Modification Library and Audio Compatibility Patch installed, I can get system wide equalization except for one thing, Google Map's voice direction audio.
I guess it's a minor problem but if I'm listening to music and Google is about to alert me the next turn, Viper stops processing and my music goes all flat while Google is speaking, and then for like a split second to a few seconds later after Google is finished speaking, Viper starts to kick in again.
I can't seem to figure it out for the life of me on how to get Viper to still process even when Google is speaking the next turn direction. Has anyone ran into this issue? Anyone managed to fix this?

Mine says "Enabled: No" and I can only sense any change on gain. When I use Bluetooth USB it still says "Speaker" in the notification box?

Last time I checked selinux must be on permissive for it to stick. Gonna try it out and I'll give you all my feedback.

Tested it out and need selinux permissive.

Just curious, does your viper still process when using Google maps navigation while playing music? My viper cuts out whenever maps is about to speak the next turn direction, and right after it's done speaking, viper will kick back in either right away or a few seconds later. I did recall trying to switch to permissive but that didn't seem to work

I don't use maps I only use Waze but without the audio so can't really tell. However I think I already had this issue, it's because it cant process some apps like when your on the phone with someone. If I use it I'll try to check

What do you mean by selinux needing to be on for it to stick? The processing? I ask because last night in my car the music didn't sound like it should. Opened V4A and flipped a toggle off then back on and all of a sudden the sound changed to what it should sound like. This happened at first on my Pixel 3xl, but later wasn't an issue at all. Not sure why.

It was for the installation of the driver in order to make it stick.
For the issue you're having, check the battery optimisation option and make sure it isn't on. I had this before and changing that fixed it.

Tried doing this and unfortunately viper still didn't process maps navigation audio :/ Thanks for sharing though!
My viper installation was able to stick without the need of changing anything related to selinux, just audio compatibility patch and audio modification library did the trick for me (minus maps navigation ofc)

[GUIDE] Get perfect surround sound from phone speaker with dolby atmos and viper4a

INTRODUCTION
*WARNING USE AT YOUR OWN RISKS*
Though the poco F1 has stereo speakers, the earpiece is sort of weak in comparison to bottom one and so the sound quality falls short when compared to other phones with dual speakers. With this guide, you can make your phone sound much balanced, immersive and better. Basically what it does is increase audio coming out from earpiece by using viper in combination with Dolby. Also this does not increases sound from earpiece beyond max level but instead reduces volume of bottom speaker slightly so it will not damage your speaker
REQUIREMENTS
Any custom rom with magisk and permissive SElinux
STEPS
1. Flash permissiver zip or use SElinux switcher to make SElinux permissive for Dolby module to work
2. Flash viper4a rootless zip in TWRP
3. Flash v4afx zip in magisk then reboot and test if Viper4A is successfully installed and working
4. Flash ACDB zip first in magisk then flash dolby audio zip and then reboot. You should now have moto audio app installed and working.
5. Put XHR WideFX irs file to main storage/Android/data/com.pittvandewitt.viperfx/files/Kernel
6. In Viper, enable convolver then choose the file to enable it.
7. For dolby, the default settings (smart audio) is great but personally I use film mode with surround sound and volume leveller enabled.
I have tested this in evolution X rom and it should work in other roms also. For stock rom it may require a custom kernel. If Dolby Atmos doesn't work then try Dolby Digital instead.
If you face issues like Dolby getting disabled automatically then heading to viper settings and switching Attach Audio Effects toggle or rebooting the system fixes it. If dolby app force closes then reflash it and clear catch after installation

on STEP 2, when i installing viper4a rootless in twrp it say done but i got red warning it say "unable to mount system"
so it is successfull or nah ? i confuse
i already installed v4afx via magisk ( STEP 3 ) and it working.
BUT
It this thing ? should i ignore it since my viper4a working ?

On first choose no then select patch (new logic) then again choose no for notification helper and select remove volume listener library
Even if you skipped it wouldn't matter much because ACP is used just to fix audio not working in some apps and it does slightly enhances audio quality and volume.
For usb dac you can choose yes if you don't use wired headphones from usb c port
For viper though, you shouldn't get that warning
Maybe problem could be in your twrp
Manually mount system in twrp then try flashing again. If it didn't work you may have to reflash recovery
But you said that it is working? Did you tested the audio also? Because the magisk module only installs the app and some configs. The drivers are installed from recovery. You can also tap on the chip like icon button in viper and it should show the driver info and enabled as yes properly

Yes even tho i got warning, but it properly working. I already use it like 6hour, all is working fine.
but when i installing Dolby Atmos, i got bootloop and force me to bootloader. but when restarting phone i can access twrp, just removing them in module via twrp everything is back normal.
but i think it doesnt support latest MIUI Global 11.0.4 ? i got stock MIUI11
Anyway, after wiping module via twrp my viper now doesnt have driver on the app. i already doing the exactly same step 1 - 3 to install viper and it didnt work rightnow. driver still doesnt work even tho i tried installing this many times.
I already go to viper4x thread, someone say need to overwrite 2 file ( post-fs-data.sh & sepolicy.rule ) but still doesnt fix driver.
maybe you know how to ? :laugh:

Dolby Atmos is known to not work as of now in stock kernel or roms for many devices as it is still under development. You can try dolby digital instead
But are you getting the same error on twrp for viper? With system not mounting?
Unfortunately I don't have much idea for viper so I can help you till the limits of my knowledge only

Anybody make it work with Pixel Experience ROM 10.0'
Hi, I want to install it and I have Pixel Experience ROM 10.0 Official. I'm curious if anybody successfully instaled it on this ROM.
Thanks

INTRODUCTION
Though the poco F1 has stereo speakers, the earpiece is kinda weak in comparison to bottom one and so it doesn't give that true stereo like audio performance (surround sound) compared to other phones with dual speakers. But with this guide, you can make your phone sound much balanced, immersive and better with Dolby Atmos and Viper. It actually feels like if the sound is coming towards you and not from the side
This requires the XHR WideFX irs. This is the only one I found till now which worked so perfectly with atmos after testing 500+ irs files.
REQUIREMENTS
Any android 9+ rom with magisk and permissive SElinux
STEPS
1. Install Audio Compability Patch first in magisk then reboot
2. Flash viper4a rootless zip in TWRP
3. Flash v4afx zip in magisk then again reboot and confirm if Viper4A is successfully installed and working
4. Flash Dolby Atmos zip file in magisk (you can download it from guitardedhero's post also for new version) and reboot. You should have both Dolby Atmos and Viper4A working at this point
5. Now to get that stereo sound effect, put XHR WideFX irs file in main storage/Viper4Android/Kernel folder
6. Open Viper and enable convolver then choose the same.
You can now test the sound and enjoy the stereo sound effect. It is best for gaming or while watching movies.
I have tested this in evolution X 4.0 rom and it should work in other roms also but I am not sure for OOS. For stock rom it may require a custom kernel. If it works in your rom then please comment down below so that others could also know it.
If you face issues regarding Dolby getting disabled automatically then heading to viper settings and switching Attach Audio Effects toggle or rebooting the system fixes it.

I have personally tested it in PE pie and Evo X 10 version. But this one should work in any android 10 based custom rom as long as you don't have any other audio mods installed conflicting it or else you may require AML also.

Thank you, in that case I think too that should work fine with Pixel Experience 10.0 ROM.

Viper is working fine but after installing Dolby Atmos and rebooting i am stuck at Fastboot, had to remove the dolby module.
Is this related to Miui 11 or some selinux problem??
Please suggest some workaround.

Will this work on miui 11?

Looks like it doesn't work in miui as of now
But you can try dolby digital instead which is also good. Dolby Atmos is still like an early release and currently only works in custom roms and kernels
But remember to choose the IRS file in viper. That makes the earpiece work more balanced. Dolby is just to further enhance the sound quality.

Same is happening in Evolution X I'm stuck at bootloader..
It's not even working in a custom rom.

Works perfectly with Pixel Experience (Android9) + No Gravity Karnel.
Thank you, so wonderful!

Thanks for stereo convolver file, but dolby atmos giving bootloop on miui 11.0.6 android 10

I'm running Pixel Experience Plus Android 10 on my poco. I've managed to get V4A to work but when I flash Dolby Atmos and reboot the device and try to open it nothing happens and after some time and after 10-15 attempts of trying to open it a crash message appears. I also tried installing Dolby Digital Plus for Android Q but that crashes as well

Make sure that SELinux is permissive as they will not work in enforcing
Flash permissiver zip file to fix it
I am also currently on PE+ latest and have not encountered any such issues
My recommendation is use Dolby digital instead as it is more stable (v7.2)

Thank you very much Sanek.
I hope this time I will manage to use your mod.

How can I set this mod up? I don't understand how to do it and I've never tried to do such a thing. Please someone help me. And does it work on miui global 11.0.1.0?

need an unlocked bootloader, the presence of magisk or twrp , if you are not familiar with these words, then do not think about modification yet

Yes I have my bootloader unlocked, I have magisk, and I have TWRP, the thing that I do not understand is what is that mixer_paths and where should I put it. That's what I don't understand. Do I have to flash the module, and then the module creates a folder where I have to put the mixer_paths in?

Same here. Latest xiaomi.eu rom and nothing happened but on the other hand the sound on earphones was totally disabled so I removed the module and everything became fine again.

Yeah, this is what I couldn't understand at the beginning as well, but later sanek posted 2 download links, one of which leads to a zip file download. This is what we need. After downloading it, you can just flash it (zip file) using either TWRP or magisk.

Doesn't work
I'm on last beta rom from xiaomi.eu

Works great on PE rom. Thanks

Is it possible to make it work on eu?

Got this working on LineageOS 17.1 before I swapped it to another Rom.
Didn't run into any issues, I will say it was difficult at first to determine if it did anything, I could hear something extra but it was hard to identify I had to get my heavy case that makes blocking the normal speaker silent to figure it out. Once I did I could notice the difference more critically.
Overall, it did add a bit more to the top end I would say.

Bug found on Crdroid 6.6
Mod disables after headphones are inserted and removed. Reverts to only using single bottom firing speaker. Any way to fix?

Pretty nice mod. I would like a bit louder the top speaker, but it sounds great.
