It is using front earpiece for media playback. I tried to gain this effect by using SoundAbout, but when i turned media on earpiece there was no sound from speaker, it was unable to use earpiece/speaker at the same time. It will be great if somebody port such mod to our device Waiting for your anwsers, guys.

Can you share the link pls?
https://forum.xda-developers.com/redmi-note-3/themes/audio-mod-hardware-based-best-audio-t3598455
This is for Snapdragon
if you've only taken a view over the threads section of this device you would've noticed that there are already 2 mods regarding your desire, one which is mine, forgotten, based only on earpiece playback, and the other, still actively developed, which has more features and improvements. Good luck flashing.

Which one gives clarity sound between Dolby and Viper4Android???

Hi Guys! I'm a little bit confused between Dolby Atmos and Viper4Android. I am a Kenzo user and currently using NOS O latest build.
So please suggest me which one should I flash? Dolby or Viper
and please give the best settings for it if you have.
Thanks in advance
Search FIRE SOUND in XDA (in our forum RN3 Pro)
Have Dolby and V4A and much other tweaks.
I love this mod
Edit: Link
Dolby, but you have to make sure that you flash the working version - some versions seem to work but actually do nothing and to make sound virtualizer work is not trivial.
Try Jetaudio music player, their plugins are actually working and doing the job great.

Sound call

you have to use directly the phone close to the ears ,..this i not good .no one is worring about this problem. I use eui couco92 and sound call very low. Please resolve this issue

[MOD][V4a][TUTORIAL] ViPER4Android - How to install

Thread to be closed.
Thanks for the guide, much appreciated!
works great on EvoX too.... Thanks for the tip
I have installed this mod on Miui eu v11.0.11 and it works beautifully. The bass is much cleaner than dolby atmos plus which has very muddy bass. The definition is also way better with viper. The only thing I'm yet to figure out is how to reduce the processing delay. It is noticeable sometimes when increasing volume or changing tracks.
Also when the bass hits there's clearly some hint of attenuation going on which makes me feel that something is limiting the overall output. I will go over the instructions for v4a because it's much more complicated than atmos. After that I can give a proper opinion.
Thanks a lot for this tutorial.

That's normal as every device will be hardware limited on the output gain. Try adding gain amplification, it might help in some cases.
There are way too many options to go through, but you will most likely find what you need.

Don't worry, v4a does not work on his A10 or 11 versions. I tried on both already. I recommend you trying other firmware. PixysOS works well.
On redmi note pro global after doing everything it shows the driver version but the rest is No's neon enabled no too . I'm on latest EU.miui

MIUI 12? I havent tried this on MIUI 12 yet. Global is still receiving the update, so I'm currently using PyxisOS.
EDIT: I've found the "fix" for the issue. Just go to Settings and enable Legacy Mode. This alone worked for me on MIUI 12.0.1 EEA Global.

Turn on legacy mode on Settings
Quick note for all those who like to install every single update out there... The newest version of v4a app (2.7.2.1) was really misbehaving on my 9s running miui eu v11.0.11 so I had to remove it. Every time a notification came in there was a loud crackling noise from the loudspeaker just before and after playing the notification tone. It's as if the speaker is turned on and off just before playing a sound but the popping sound was extremely annoying. Also, the app obviously isn't optimized to work on the rom because it could only work in compatibility mode. Disabling compatibility mode made the app unresponsive and sometimes it froze up the entire system forcing me to hard reboot. Loading ddc and irs presets was hit and miss at best.
Anyone wishing to update the v4a app from v2.7.1.6 be warned. If you decide to update anyway, let us know if it works well for you and your rom setup.
PS: I just stumbled across the ddc and irs profiles for my iems and I'm completely sold. Viper4Android is the king of sound mods. Dolby can't touch a hair on it. I knew that my once timid redmi note 9s was a music giant. It just needed to be woken up and v4a was the adrenaline shot it needed.
I just couldn't live with the crappy sound of the stock rom knowing that the Texas Instruments TAS2562 Class-D Audio Amplifier in my phone was capable of putting out up to 6w of power.

Can you share those profiles? I tried the latest v4a and it wouldn't work. It just wasn't active when I clicked on the chip icon.

To make v4a work just go back to version 2.7.1.6.
DDC profiles are specific to the headphones they're calibrated for. If you try them on different headphones they will sound like crap because every headphone model is tuned differently by the manufacturer.

Actually it works in legacy mode after removing Audio modification library and rebooting.

Thanks. I didn't try that. Is it completely stable?

It is. No problem with notification sound. Didn't notice any instability.

Keep testing. I'm not going to reinstall it just yet. I don't even see a big difference over the previous version. The most notable changes target android 11.

I can confirm this, V4A FX 2.7.2.1 work on 11.0.10.0 without Audio Modification Libary.
I just needed to enable legacy mode, it seems stable and without any bugs.
I will report back in a few days if something is wrong
12/11/2020 edit: yup, everything seems to be fine
Seems like V4A doesn't work on Redmi Note 9S with MIUI 12.0.2 Global, or atleast it doesn't work on my RN9S. I've tried everything mensioned here and on other forums but I always get
Neon enabled: No
Status: Abnormal
Audio Format: Unsupported.
Ive literally ran out of ideas now.
[Update] I finally got it working. I remembered that some years back, in order to get V4A working we had to change SELinux from "Enforce" to "Permissive". So I downloaded SELinuxModeChanger, changed SELinux to "Permissive" and now V4A is working great. To keep V4A working after every reboot I have to change SELinux to "Permissive", which I don't really mind...
Thanks for the update, helped me get v4a processing again on v12. I knew about the selinux restriction but it was so long ago I completely forgot about it. Good thing SELinuxModeChanger still works despite not being updated for 3 years

Low audio on headphones on last update

Does anybody have this kind of problem since last update 11.0.11.0 on redmi note 9s?
I had this problem on stock rom and miui eu but I installed dolby digital and the volume is much better. It's a lot louder and with the dolby presets it seems to have higher definition and much wider soundstage. I use music preset with volume leveler and open eq.

this is not because of the update. this is long issue and permanent, atleast in selective region. solution for this is change your region to st. helena then reboot ur phone
I like to try out new things so I installed viper4android and the results are phenomenal. @Urosz you should skip dolby and install viper. My audio is so much better than it was with dolby. Dolby made the phone louder but it was quite muddy. Viper is a lot crisper and you have control over a lot more aspects of the audio. Try viper and you won't regret it.
Another audio mod I loved is Ainur Sauron or narsil but unfortunately there's no compatible version for curtana.

Is viper in flashable mod format or a magisk module? Can you link to it?

It is not in a flashable zip but it uses magisk to alter system files systelmlessly. In magisk you need to install audio modification library from the online repo and then the viper apk. Here is a thread with instructions that work for installing v4a perfectly. Make sure you follow the instructions to the letter. Otherwise you'll have to start afresh. There's no risk of bricking your device during this installation.

Also, i found that the newest viper does not work well unless you enable legacy mode which I don't like because it means that something in it doesn't work well on our system. I have the previous version which is flawless but it isn't available from the viper download page. I have uploaded it on my mega cloud drive. You can download it using this link... Happy modding. Thumbs up if this eventually solves your low audio issue.
