Hey do you edit anything in the kernel or just the mixer files ?
[Xiaomi Mi A1 Themes, Apps, and Mods] Rakibboss:
In magisk version it only enables the earpiece and disables loudspeaker.. In TWRP version i think it doesn't work. I'm on Resurrection remix latest build of Oreo
[Xiaomi Mi A1 Themes, Apps, and Mods] berezker:
It doesn't work for custom roms

Only stock
[Xiaomi Mi A1 Themes, Apps, and Mods] Rakibboss:
Then please make it compatible for custom ROM.. Cause a lot of men who are gonna modify their phone will be using custom ROM.

[Xiaomi Mi A1 Themes, Apps, and Mods] Ritwik Rahman:
Please Fix the Bugs Bro...

After last security update... Only Earpiece Works... But the Loudspeaker doesn't... I m on AEX rom with stock kernel

Edit : Found the bug....

Bug is on "audio_platform_info.xml"

Change only the "mixer_paths.xml" and keep the "audio_platform_info.xml" to stock.... Works perfectly...

(On latest AEX 8.1)

Doesn't work properly

I used it on my Mi A1 (running crDroid android 8.1) with magisk but it only swaps the speakers so the main sound comes through the earpiece and little to no sound from the bottom speaker. Please fix because now the sound is worse

Hi Dante63,

It seems you are the only one familiar with the audio issue of Mi A1.

I have a big problem with ECHO when using Video Calls (viebr, skype, etc).

I flashed LineAge OS thinking the original ROM has the issue, but unfortunately the same situation with custom ROMs.

Could you have a look at the issue?
[Xiaomi Mi A1 Themes, Apps, and Mods] justboryata:
An update coming for Android Pie custom ROMS and eventually Stock if it gets released? Was a great mod but it doesn't work in Lineage OS 16 (Android Pie Unofficial).

@OP?
[Xiaomi Mi A1 Themes, Apps, and Mods] Holotic:
Sound only plays through earpiece on LOS16
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
I'll be updating the thread referencing my main soundmod thread, there is a tutorial released for all of you to learn how to make your own if it's not compatible and fix any issues that comes up to you...
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
I'm pretty sure ORIGINAL has all stock files... ?
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
That would require logcat which I don't have time to read unfortunately, as for being familiar is because I relied on feedbacks from certain users that dedicated time to assist me in solving most problems, none of them however reported such echo issue...

I've retired from making the soundmod and made a tutorial and will update the thread to include it...

But hey, why not provide me a logcat, make it very short... Place a shortcut of the app making echo as well logcat app on your home screen...

Start logcat and immediately start the echoing app and make sure you hear the echo twice at least and stop logcat, this will tell me which paths and policy are being used and know where to modify...

I'll release a video for fixing such problems... If you're interested that is...
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
LOS incompatible as I believe either the mixers are different or the kernel is rewritten, either you make it by following the tutorial in my signature and try your luck if kernel was untouched or unfortunately won't work...
[Xiaomi Mi A1 Themes, Apps, and Mods] justboryata:
So this works only on stock kernels?
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
In general, stock ROM because it may not be the kernel but the custom ROM use different mixers too...

Seen and worked on such cases..
[Xiaomi Mi A1 Themes, Apps, and Mods] justboryata:
I don't see where is the tutorial, I would like to build the mod if I can.

[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
Please wait and don't flash anything yet...

I did zip it wrongly...

UPDATE:

re-uploaded the zip files, my sincere Apology for such error...
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
Drive Files Fixed Now...

Sorry for the trouble...

Dual Speaker enables the earpiece when playing media....

I mentioned clearly to make a backup even if I uploaded the original mixers by simply renaming it "*.bak"...

The possible reason it's not working is permissions,

Did you change the permissions of the mixers to 644 (rw- r-- r--)

wrong permissions will fail to read...

Even if you put back the original mixers...

Permissions must be 644 (rw- r-- r--)
[Xiaomi Mi A1 Themes, Apps, and Mods] Hugwalk:
I wonder if this can be used as stereo, instead of mono on 2 speakers?
[Xiaomi Mi A1 Themes, Apps, and Mods] pradhyu69:
yes i did everything right just i used ur uploaded original mixer didnt backup mine.Maybe thats the prob?

will try again with magisk module

with magisk module it works thanx
[Xiaomi Mi A1 Themes, Apps, and Mods] tanapak1:
Tried magisk with 8.1.10 rom and it's working.

if it can be stereo it would be superb.
[Xiaomi Mi A1 Themes, Apps, and Mods] pyaganti:
Does it mean we get stereo effect by using rear speaker for one channel and front speaker for other channel?
[Xiaomi Mi A1 Themes, Apps, and Mods] Ist_2004:
Will it affect , I am using viper4android?
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
As long no noise and crackles, it is safe to use....

If Magisk Module works then it's the permissions of the mixers...

If you want your original mixers to work you MUST change the mixer Permissions to 644 (rw- r-- r--), You do understand what I mean by changing permissions?

I have put for the lines of code to adjust the volume of the speaker and earpiece, they are set at default values which is considered as safe...

You can adjust it to your needs and report back the best settings without any other soundmods and I'll make it available for other users to download it immediately...

Make sure there are no Noise or Crackles, to avoid permanent damage to either speakers...

Gradually change the values as well gradually increase your phone volume when testing...

Again, Avoid Noise and crackles even if it was minor...

Happy Modding everyone...
[Xiaomi Mi A1 Themes, Apps, and Mods] Ist_2004:
Does this do only enable both the speakers or anything more?
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
Only enables the speakers with lines of code to adjust the volume, Already mentioned which lines to adjust...

Because I don't own the device, I left the values at default which are safe... it's possible to increase the values and remain at safe level...

I'll update the thread now...
[Xiaomi Mi A1 Themes, Apps, and Mods] pradhyu69:
Yes i know how to change permissions.

Dont know may be i made some mistake but its all working now..

Have one question though if i want to remove this i just have to remove module only right? Or i have to replace mixer file?

And i just found this app called earpiece which works with this mod.

It has toggle which disables main speaker (only earpiece speaker works) also has volume boost option.

Could u work on this and make toggle for this mode to disable earpiece speaker ?

Thanx

Sir,

Please add dual app feature for mi a 1 without any advertiesment.
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
That's the problem,

If you disable/remove Magisk Module,

your phone will use the Original Mixers, which you already mentioned they are not working for you...

I suggest you disable the Magisk Module & fix the original mixers since I am still here, I could help, before I move to the next device...

Take a screenshot of the mixers permission...

Application to control the volume isn't universal for all devices,

the best thing I could say is to go back to the person who created this apk or refer me to him/his thread...
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
I don't make applications...

Please, [MENTION=4970751]Rajeev[/MENTION] Kindly assist this user in making his original mixers work if they are still not working as you're more familiar with the structure of the Phone Android Oreo than I am...

it happens to me to, im using manual ways to install it
[Xiaomi Mi A1 Themes, Apps, and Mods] ludditefornow:
Hi, I have just read through this whole thread and I'm a bit confused. Can you please clarify these points.

1. Is the OREO_MAGISK_Xiaomi_mi_A1_DualSpeaker.zip working with Magisk in Nougat? I see where someone tested it and they said it worked.

2. Is the Magisk install changing any system files long term or just changing system files like usual?
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
So Magisk and Manual are the same, You're not using Android Nougat, and your WhatsApp is updated to the latest and not beta from (WhatsApp Official Download), not the PlayStore as PlayStore update are always delayed...

It shouldn't work on Nougat because Nougat uses files in Path (system/etc) while Oreo uses in Path (system/vendor/etc), perhaps he tweaked it...

A1. I am not sure about the file structure if they are the same, so please upload your mixer_paths_mtp.xml for me so I can compare and verify...

A2. changing system files like usual...

It shouldn't but if you hear noise or crackles either you decrease the sound from Dolby MOD or you edit and lower the volume levels in this MOD...

I'll Consider making an Application but it will take a very long time since I am making SoundMods for many devices...
[Xiaomi Mi A1 Themes, Apps, and Mods] jack404:
Im running on latest Oreo, i am using Play Store version, before iam replacing the mixer i can play voice note on whatsapp, but after it i cant
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:

[Xiaomi Mi A1 Themes, Apps, and Mods] Rajeev:
Sorry my friend. I went to Kerala (my native). I don't have A1 with me now. Using Honor 6x
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
No problem, I'm also doing a mod for Honor 6x I could use your help since you know how loud the earpiece could reach, current tester is new, I'll PM you the details if it's not a problem...
[Xiaomi Mi A1 Themes, Apps, and Mods] Rajeev:
Sorry my friend. That Honor 6x is not mine. Its my wife's mobile. Its pure stock. Not rooted :o
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
No worries, I'll keep trying with my tester...
[Xiaomi Mi A1 Themes, Apps, and Mods] ludditefornow:
Here's the file. Change the extension back to .xml. It was located in system/system/etc as well as system/sbin/.core/mirror/system/etc... I'm assuming this second location is the other slot (A or B) on this phone.

Also, could this xml file hold the key to the hissing sound we assume is caused by the built in amp as noted here:
[Xiaomi Mi A1 Themes, Apps, and Mods] Sachin1998:
Can u contact me machaa .. me 2 frm kerala.. want to know about mods of mia1 ..
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
The needed file should be located in system/etc for Nougat... Other paths are not required...

I'll have a look as soon I'm done from what I have in my hands...

DualSpeaker = phone speaker + earpiece...
[Xiaomi Mi A1 Themes, Apps, and Mods] gougous3:
Completely working on Nougats first December patch.

The only thing it is lacking is channel separation (Earpiece acting as left and Speaker acting as right)

It would also be great if the volume difference between the two got smaller

Stereo recording would be the icing on the cake.
[Xiaomi Mi A1 Themes, Apps, and Mods] Alyx89:
ok so i patched the magisk module but no changes. any extra steps i need to take to make it active and working?

edit: whatsapp voice msgs not working for me after patching the module
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
I'll have a look but as far as I know earpiece has always been mono-left as for the speaker, are you sure it's right, install from the playstore any "left right speaker test" & see if it's mono or stereo...

Patched as in volume levels?

For Whatsapp voice notes issue, I Don't Have Testers, Any Volunteers?
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
I had a look at the mixer file, they are identical to the original mixers provided...

Oreo and Nougat are the same, I'll make a TWRP and Magisk for Nougat...
[Xiaomi Mi A1 Themes, Apps, and Mods] Alyx89:
As in installed it as a normal magisk module, as for testing sure just send me the fix with instructions I'll do my best. Thanks
[Xiaomi Mi A1 Themes, Apps, and Mods] gougous3:
I don't need to install that, I've already tested it, it's mono. It's totally possible though, there's a mod out there that brings the Earpiece in stereo but it's not for our device.
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
It's all depends on the speaker, take my phone for example Samsung Galaxy Note 8...

the earpiece is mono-left... one thing I could investigate is to make the earpiece play mono instead of stereo...

you see, when the phone settings is set to play stereo, the speaker will play left & right accordingly,

but the earpiece has only left and thus when right output is played, nothing comes out from the earpiece,

I could try forcing the earpiece to always play sounds regardless....
[Xiaomi Mi A1 Themes, Apps, and Mods] gougous3:
I think you misunderstood me, our problem is that we are actually just playing mono audio from 2 different sources (earpiece is playing both left and right channels, the speaker does that also) when we should play it stereo (so earpiece gets only left channel and the speaker gets the right channel, or vice versa)
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
So you want me to disable the speaker left channel, so you have the earpiece as left & speaker as right?

You'll lose quality...
[Xiaomi Mi A1 Themes, Apps, and Mods] ludditefornow:
Maybe make a different magisk option that gives ear speaker left channel only and main speaker right channel only and name it accordingly.

Keep the current Magisk creating of having left and right channels running through both speakers as the other option.

Thanks, that works. I will check and see if levels can be adjusted up on both speakers without distortion.
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
Once the whatsapp issue is solved as I ran out of testers, and some other testers aren't responding to test the fix,

If I am done from fixing the issue, I will try to make the other Magisk Module for left right speaker experience...
[Xiaomi Mi A1 Themes, Apps, and Mods] just.rixter:

[Xiaomi Mi A1 Themes, Apps, and Mods] Rauchy988:
The same problem.
[Xiaomi Mi A1 Themes, Apps, and Mods] ludditefornow:
When you mentioned "earphone" in the OP, did you mean "handset"?

[B]<path name="handset"[/B]>
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RDAC2 MUX" value="RX1" />
<ctl name="RX1 Digital Volume" value="84" />

The only path name I can find in the XML thAt is set to 84 is 'handset"... Is this correct?

Also, can you shed any light on the line regarding 8.5 volts?

<path name="speaker">
<ctl name=[B]"Boost Output Voltage" value="8.5V"[/B] />
<ctl name="Left Feedback Enable" value="ON" />
<!--
<ctl name="DRE EN" value="1" />
<ctl name="Ramp Switch" value="0" />
<ctl name="Amp DSP Enable" value="1" />
<ctl name="Amp Volume Location" value="0" />
-->
<ctl name="Speaker Volume" value="5" />
<ctl name="Digital Gain" value="56" />
<ctl name="Left Channel Enable" value="1" />

This might affect people with hissing noise. Also, if the amp is 10 volt, why is the output set to 8.5 volts?
[Xiaomi Mi A1 Themes, Apps, and Mods] Sachin1998:
Can u give the Link for fixed one ?
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
Unfortunately, something is wrong, I'll take the link down to rebuild the mixers from scratch...

Patience please and sorry for the trouble...

Original mixers will be available...

No the DIY is to be applied on the SoundMod I have created, in the path "speaker" you'll find what I highlighted, as for the voltage and other things I can't really do much but investigate and try because I don't have the phone... If you want to be the tester, please PM me a recorded video of the hissing sound if possible and explain further about it...

Currently the mod has issue, once I'm done solving the issue... I'll see about the hissing...

Again I apologize to everyone...
[Xiaomi Mi A1 Themes, Apps, and Mods] gougous3:
I think I won't lose quality if I set the volume levels right. In fact, it would be the contrary
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
Very well, let me just fix this mod and I'll make the left right MOD you want...
[Xiaomi Mi A1 Themes, Apps, and Mods] Dante63:
Fixed sound issue, some apps you'll hear dualspeaker & some single speaker, it's kernel related, not in my hands...

Thank you [MENTION=5366227]black_arashi[/MENTION] for your help and the photos, I have used them already...

As for the Stereo Mod:

I'll have a look and see if I can do the left earpiece right speaker magisk mod...

PS: I'd like to know more about the hissing sound...
