Dude the speaker volume isn't low it's good and loud enough. Our speaker is a mono speaker that means no stereo but you can install dolby surround or viper4android and so on. I hope i could help you a bit.

Thanks OP it's working on mi mix 3
[Xiaomi Mi 8 Themes, Apps, and Mods] bluviper:
Magisk Flash? is that a module? or are you referring to Magisk Rooting app itself?

Im on Mi Mix 3, is that even possible?

---------- Post added at 03:40 PM ---------- Previous post was at 03:23 PM ----------

did you perform the steps on the first post?

or did you also install Sphinx Kernel over Mi Mix 3?
[Xiaomi Mi 8 Themes, Apps, and Mods] lucaci.ed:
I don't know if there is Sphinx kernel for MI mix 3, but the mod is a magisk module, so you could just try to add it manually. If it doesn't work or it's buggy, just remove the module.

However the module was made for mi 8, consequently it couldn't be optimized for your device
[Xiaomi Mi 8 Themes, Apps, and Mods] bluviper:
yup, that is sad. but someone did it on his Mix 3.

but then again, think ill wait further for the proper MOD
[Xiaomi Mi 8 Themes, Apps, and Mods] lucaci.ed:
I just had a research and it looks like the mi mix 3 has a function called super earpiece. If you already reached the maximum volume steps and you press one more time volume up, the earpiece I boosted by almost by 30% the audio level.

It looks like the mi mix 3 earpiece is much better and louder than mi 8, so in my opinion you could safely try it (remember the hardware of mi 8 and mi mix 3 are 90% the same)

---------- Post added at 10:58 AM ---------- Previous post was at 10:11 AM ----------

Probably won't work, for me on miui worked just with Sphinx. Before the version with update audio libs, you and Andrew tried to help me on telegram, but it never worked..
[Xiaomi Mi 8 Themes, Apps, and Mods] 954wrecker:
Thats interesting, I simply installed the Magisk module on my mix 3 and it worked fine.
[Xiaomi Mi 8 Themes, Apps, and Mods] lucaci.ed:
Just check if the sound has distorsion while it's maxed, also during a call try both earpiece and speakerphone. After that please post a review for the others with a mi mix 3
[Xiaomi Mi 8 Themes, Apps, and Mods] apokit:
Fe
[Xiaomi Mi 8 Themes, Apps, and Mods] bluviper:
I just dived in. installed the module via Magisk. rebooted. and i have the stereo setup.

playing at FULL volume... no distortion at all. atleast on EDM and POP. not into ROCK or METAL *lol*

thanks again sir!

all I need now is sound boost. i got it all stereo. but its still soft. i need to crank it up full. but notifications are kinda soft.

there are lots or things going here to boost. just dunno where to start
[Xiaomi Mi 8 Themes, Apps, and Mods] lucaci.ed:
Now just ask [MENTION=4561985]acervenky[/MENTION] what value you have to modify to boost the volume level, I suggest you to go soft while you are increasing values for example: if the master volume is 75, try to set il 76 and check the sound before you go 77

[Xiaomi Mi 8 Themes, Apps, and Mods] cool400:
How does this mod compare with VIPER4Android FX? There's a Magisk-module for V4A.

Do you guys use this for sound-output via the inbuit speaker, or for sound over headphones/bluetooth?
[Xiaomi Mi 8 Themes, Apps, and Mods] 954wrecker:
this mod is only for sound out of the earpiece
[Xiaomi Mi 8 Themes, Apps, and Mods] cool400:
So, you mean when I hold the phone on my ear? Not the speaker at the bottom?

Can I install this mod together with V4A without killing one or both of it?
[Xiaomi Mi 8 Themes, Apps, and Mods] darkwader18701:
Dude dual speaker mod activates the earspeaker too, you can listen music and the sound comes from both speakers. Im using the viper mod that i posted (link) because the viper module from magisk caused distorted sound, that means it depends which rom you're using and so on. On miui no distorted sound but on aosp roms yes, understand? [emoji1787]

Hello guys, please test out the attached AML compatible version. This will be a universal zip to enable stereo speaker mod for all the MI devices running on SD845 platform :)

[Xiaomi Mi 8 Themes, Apps, and Mods] HenryLeonheart:
Can someone tell me the steps they took to make this mod work on Xiaomi.eu latest version? Tried installing on magisk 18 v1 and after it not working, tried v2. Still haven't tried the way for custom roms according to the op since u wasn't sure if it could be considered a custom rom or not. I have sphinx 2.3 installed. Also had some audio mods previously installed but removed them all to see if it could be an incompatibility. Thank you.
[Xiaomi Mi 8 Themes, Apps, and Mods] najabi:
Hi.. Thanks for the mod! It works for me, but I'd say volume on earpiece is quite low.. I can barely hear it, I have to put on earpiece to check that it sounds.

I am on 9.1.3 EU, Sphynx 2.3 kernel and Magisk 18 stable.
[Xiaomi Mi 8 Themes, Apps, and Mods] riyosakura:
Will this mod shorten the lifepsan of earpiece?

I read about earpiece as speaker can shorten the lifespan of the earpiece.

Its something like this

Is this true? Can anyone confirm this technically

Thank you.
[Xiaomi Mi 8 Themes, Apps, and Mods] nfsmw_gr:
Lol no, people on xda have used these kinds of mods for years with no issues.

Only problem you could have is if you set the volume too high to the point sound distorts.

Besides you can easily clean your speaker grills with off the self specialized cell phone port cleaners, or just a toothbrush and some isopropyl alcohol. (tried it myself, works fine)
[Xiaomi Mi 8 Themes, Apps, and Mods] riyosakura:

Is the OP one called v1? What improvements on v2? If I update the Custom Rom, do I need to remove this first?
[Xiaomi Mi 8 Themes, Apps, and Mods] Hanslau:
Great work, thanks OP! Is this a true stereo mod or does it just play mono sound from both speakers?
[Xiaomi Mi 8 Themes, Apps, and Mods] fattymcdirty:
The AML Version sadly doesn't work when using V4A and Dolby Digital PIE - could u adjust it so it actually works? :)
[Xiaomi Mi 8 Themes, Apps, and Mods] louis-JYG4t:
This is indeed just mono playing through both speakers.

[MENTION=4561985]acervenky[/MENTION]

Are there any bugs present in this mod at the moment? Call problems, bluetooth sound,...?
[Xiaomi Mi 8 Themes, Apps, and Mods] lucaci.ed:
It works with the Sphinx kernel!

I already talked about it since for me the mod wasn't working without the kernel on MIUI eu
[Xiaomi Mi 8 Themes, Apps, and Mods] IURII G:

I tried this with my own made dual speaker mod and at first boot it also didn't work on stock miui music player.

Then I rebooted to try all of this again but the stock miui player played through both speakers directly.

I found the culprit that brake my bluetooth audio. In my end its pix3lify mod.

Without the mod, bluetooth audio is working properly.

My setup is LOS 16, with viper4android magisk module and a couple of other modules.

I've asked for the problem in pix3lify thread, but no answer yet atm. I thought there is some problem with call screening which is included in pix3lify mod.

If you on pixel experience maybe the problem is with the call screening feature which is included in the ROM.

thank you. I have viper4android and the bluetooth audio is working properly.

What rom are you using?

Did you use pix3lify mod?
