Audio coming from wrong side of Headphones left right swapped - Xiaomi Mi 8 Lite Questions & Answers

I recently started playing online game PUBG MOBILE and i realized that my sound is coming from wrong side of headphones. Then i watched testing videos of left right sounds and realized that my phone have a problem sound is coming from wrong side of Headphones. I tried different headphones but same result, i tried these headphones in other mobiles then i found everything is okay, so the result is my phone is playing audio on wrong side of Headphones. I can't play pubg any body have a solution?
What should i do?
Is there any software option to swap audio?

Try to reinstall again the rom. This should fix your problem

Hello do you got any problem again? Open mixer paths_static.xml using root explorer and invert the RX1 and RX2 outputs.. HOW? Simple.
Your headphones settings should be like that :
<path name="headphones">
<ctl name="INT0_MI2S_RX Channels" value="Two" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RX2 MIX1 INP1" value="RX2" />
<ctl name="RDAC2 MUX" value="RX2" />
<ctl name="RX HPH Mode" value="HD2" />
<ctl name="COMP0 RX1" value="0" />
<ctl name="COMP0 RX2" value="0" />
<ctl name="HPHL" value="Switch" />
<ctl name="HPHR" value="Switch" />
<ctl name="RX1 Digital Volume" value="95" />
<ctl name="RX2 Digital Volume" value="95" />
</path>
You must invert the output. Like this :
<path name="headphones">
<ctl name="INT0_MI2S_RX Channels" value="Two" />
<ctl name="RX2 MIX1 INP1" value="RX2" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RDAC2 MUX" value="RX2" />
<ctl name="RX HPH Mode" value="HD2" />
<ctl name="COMP0 RX1" value="0" />
<ctl name="COMP0 RX2" value="0" />
<ctl name="HPHL" value="Switch" />
<ctl name="HPHR" value="Switch" />
<ctl name="RX2 Digital Volume" value="95" />
<ctl name="RX1 Digital Volume" value="95" />
</path>
And after doing that open your other mixer called mixer paths.xml and look for the next line, edit what I edited
<path name="headphones">
<ctl name="INT0_MI2S_RX Channels" value="Two" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RX2 MIX1 INP1" value="RX2" />
<ctl name="RDAC2 MUX" value="RX2" />
<ctl name="RX HPH Mode" value="HD2" />
<ctl name="COMP0 RX1" value="1" />
<ctl name="COMP0 RX2" value="1" />
<ctl name="HPHL" value="Switch" />
<ctl name="HPHR" value="Switch" />
</path>
This is the original settings. Now you change to this settings:
<path name="headphones">
<ctl name="INT0_MI2S_RX Channels" value="Two" />
<ctl name="RX2 MIX1 INP1" value="RX2" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RDAC2 MUX" value="RX2" />
<ctl name="RX HPH Mode" value="HD2" />
<ctl name="COMP0 RX1" value="1" />
<ctl name="COMP0 RX2" value="1" />
<ctl name="HPHL" value="Switch" />
<ctl name="HPHR" value="Switch" />
</path>
Both of mixer need to be edited like that. I Tested before I share it and it works.
Back up your mixer paths first.
Good luck

[Mod] [Root] Play Media Sound on Front and Rear Speakers Simultaneously

Credit for this goes to @langeveld024, in this thread: http://forum.xda-developers.com/lg-g3/themes-apps/g3-t2936465
I've only modified and tested it for the Sprint LS990 version.
You need to be rooted, and use a root editor to modify the mixer_paths.xml file.
1. Make a backup of your existing file. You might want to make a nandroid backup so if something goes badly wrong you can recover easily.
2. In your root editor, search for the text string "speaker" (with the quote marks). You should find this path:
<path name="speaker">
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="One" />
<ctl name="RX3 MIX1 INP1" value="RX1" />
<ctl name="RX3 Digital Volume" value="60" />
<ctl name="RX4 Digital Volume" value="60" />
<ctl name="RDAC5 MUX" value="DEM3_INV" />
<ctl name="LINEOUT1 Volume" value="16" />
<ctl name="LINEOUT3 Volume" value="16" />
<ctl name="RX3 HPF cut off" value="MIN_3DB_150Hz" />
<ctl name="SPK Amp Volume" value="3" />
</path>
ABOVE the row <ctl name="RX3 Digital Volume" value="60" />
insert this line. I copied the existing RX3 Digital Volume row, pasted it, and changed RX3 to RX1.
<ctl name="RX1 Digital Volume" value="60" />
When complete, it should look like this:
<path name="speaker">
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="One" />
<ctl name="RX3 MIX1 INP1" value="RX1" />
<ctl name="RX1 Digital Volume" value="60" />
<ctl name="RX3 Digital Volume" value="75" />
<ctl name="RX4 Digital Volume" value="60" />
<ctl name="RDAC5 MUX" value="DEM3_INV" />
<ctl name="LINEOUT1 Volume" value="16" />
<ctl name="LINEOUT3 Volume" value="16" />
<ctl name="RX3 HPF cut off" value="MIN_3DB_150Hz" />
<ctl name="SPK Amp Volume" value="3" />
</path>
A couple of notes:
(1) Your values may be different than 60. I've edited my mixer_paths multiple times, and no longer remember what the original values are. If yours are different, you can leave them at your current settings.
(2) RX1 = the earpiece, RX3 = the rear speaker. I set the rear speaker louder to get better balance between the two when the phone is face up.
(3) The sound seems to still be mono, not stereo, but there's a noticeable improvement in the sound quality when viewing videos.
Finally, save the file. Make sure permissions are 0644 (rw-,r--,r--). And reboot.
@meyerweb
The top lines should be like this:
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM RX2 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="Two" />
<ctl name="RX3 MIX1 INP1" value="RX1" />
<ctl name="RX1 MIX1 INP1" value="RX2" />
Then it will be stereo

Oh and u might want to add some of these, IF present in headphone path:
<ctl name="COMP0 Switch" value="1" />
<ctl name="DAC1 Switch" value="1" />
<ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX1" />
<ctl name="HPHL DAC Switch" value="1" />
<ctl name="HPHL Volume" value="30" />
<ctl name="HPHR Volume" value="30" /
Great find.

These will complete a proper configuration, but only if these line's are also found in the headphones path.
Cuz I pasted it from a note 4 path xD
I've made several surround sound mods for several device's (S5, xperia SP, LG G3, and put some time in others who wanna make it for LG G2 and note 4) and in almost every case some of these line's and maybe others may be needed for proper surround sound.
But it is very important to not copy my work by using line's found in some of my mods.
Every mod is device specific and therefore in every device may be other lines be used.
The base principal is the same for any device but it is very important to look in the headphones path and speaker-ear path. Use only those lines.
The lines I posted above are (as I said earlier this post) lines from a note 4, but may appear in ur stock headphones section or so.
The note 4 lines I posted as example will tell the earpiece to play better and louder and will help you to create real stereo effect. (At least, that's what I found out by trial and error)
If u want me to make an test version, send me the file and I'll look into it :thumbup:
Thanks. Attached my mixer_paths file. I haven't had time today to look into it and see if I have those lines or not.

Anyone have tihs working on ZV6? I am running stock ZV6 and cannot get this working. Tried editing myself and tried downloading one in post. It doesn't play anything out the front speaker.
You're on a rooted ZV6?
I'm using it on BarRin, which is a slimmed down ZV6, and it's working fine. Did you make sure permissions were set correctly after modding the file?
One more thought: Did you make only the changes in post #1, or did you also make the changes in post #2? I could never get those to work correctly.
Has anyone tested this on CM12?
Yes sorry assumed that I was rooted is implied to be even attempting this. I have only done post 1 mods, not trying to get stereo going. Permissions are correct, etc. It's not a big deal the increased sound level worked so that speaker by itself is much louder now anyway.

How can I make notifications louder?

I have the volume settings maxed out.
Audio while video plays seems acceptable though.
I think I found my own answer. Edit /system/etc/mixer_paths.xml values with root.

But which lines are you editing? I'd like to know this as well.

I changed a couple from 81-84 to 90 I think under the speaker parts.
Volume on calls is kind of low too. Maybe I'm just getting old ha.

No, I agree with you that the call volume is low for the most part. But which values did you change and under which categories? I know you should change "RX1 Digital Volume" for some (or is it RX2?). No idea, that's why I'm curious what you did.
It's close to the bottom of the file. There was a section with speaker in quotes. I was surprised that at the top it said some rx defaults were 84 and they were set to 81.
I'm trying 90 and I changed my notification sounds.
Kind of followed this

which values would you change to raise headphone volume?

I'm not even sure if what I did did anything. Just save a copy of those two mixer XML files first.

I didn't attach anything. There are some 81, 84 I switched to 90 and a 89 to 93.
I only care about the speakers for now. Updated to 2.1.3 to see if that helps also.
I tried to edit mixer_paths.xml but I really don't know where to modify. In the Oneplus One guide is easy to modify. On our phone is more complicated. I want to modify only In-Call volume.
Below are all the options that are related to the volume. I think that the In-Call volume is on "handset" and "voip-handset" and "anc-handset".

How to change the first microphone to second microhpone in "mixer_patchs.xml" ?

How to change the first microphone to second microhpone in "mixer_patchs.xml" ?
Hi Friends
I have damaged the front microphone to talk but the second microphone is working.
I would like to change to make the system does not use a microphone first during a telephone conversation
I would like the system to use another microphone during talks.
I think that the microphone config should be placed in the file mixer_patchs.xml
The problem is that I cantdistinguish which microphone is named.
Please Help.
Phone Xperia SP but I think that this file is for all android device.
mixer_patchs.xml
<mixer>
<!-- These are the initial mixer settings -->
<!--
NOTE: For all the mixer controls added under usecases or sound devices
-->
<!--
we should have an initial mixer setting (default value)

I need this on my Z3C, whith Zq like look, UP!

How does /etc/mixer_paths.xml TinyAlsa ctl/path routing work?

/etc/mixer_paths.xml is apparently related to TinyAlsa (https://stackoverflow.com/questions/26923301/understanding-mixer-paths-xml-in-android).
The file can be edited to reroute or alter audio. "adb root && adb remount && adb push mixer_paths.xml /etc/ && adb reboot"
The file starts with a series of default parameters. I assume each corresponds to a hardware/ALSA value or rounting preference.
XML:
<ctl name="Voice Rx Device Mute" id="0" value="0" />
"id" is used when multiple controls appear under the same name. It's like an indexing scheme.
<ctl name="Voip Mode Config" value="12" />
<ctl name="SLIM_0_RX Channels" value="One" />
<ctl name="SLIM_0_TX Channels" value="One" />
Then there are a series of profiles, which override default parameters.
XML:
<path name="headphones">
...
<ctl name="HPHL DAC Switch" value="1" />
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
<ctl name="RX1 Digital Volume" value="82" />
<ctl name="RX2 Digital Volume" value="82" />
<ctl name="COMP1 Switch" value="1" />
</path>
I observed that changed "RX1/2 Digital Volume" changed the output volume. "HPHL/R Volume" had no effect.
Some paths include an inner "path name=" tag. I assume this inherits settings.
XML:
<path name="voice-line">
<path name="voice-headphones" />
</path>
<path name="voice-headphones">
<path name="headphones" />
<ctl name="COMP1 Switch" value="1" />
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
<ctl name="RX1 Digital Volume" value="78" />
<ctl name="RX2 Digital Volume" value="78" />
</path>
--------
Now the kicker... What do path names mean?
For example, "headphones" obviously means headphone port, and "speaker" means speakers.
However, there are literally hundreds of speaker, headphones, headsets, handsets, mic, sidetone-iir, tty, etc... How does Android choose which path to enable?
If I'm trying to decrease headphone volume (for earbuds), which settings do I have to change? "headphones" only, or some unknown set of options?
I noticed an interesting <path name="ADSP testfwk">... What could that mean?
A Google search took me to http://www.perkel.com/x/snd_soc_msm . Searching `snd_soc_msm` took me to https://android.googlesource.com/pl.../4765c43/libalsa-intf/snd_soc_msm/snd_soc_msm... The log link references "mako" (Nexus 4), not my Nexus 5X (this is the first commit the file appears). Additionally, the file is not available in "master" branch (replace the hex with master), as apparently libalsa was removed.

---------
Yes change "headphones" only
<ctl name="RX1 Digital Volume" value="82" />
<ctl name="RX2 Digital Volume" value="82" />
I don't want people saying "change headphones only".
I'm a programmer. I want to know what the different options mean, which files in the Android source code associates different phone/call/Bluetooth states with different audio paths, and documentation on which paths are used/unused, and when.
Because I want proof that my ears won't get blown out when I get a call, or some app happens to output audio to the wrong path, etc.
Did you ever find any documentation on this? There seem to be many posts about changing this or that, but where are they getting the information from on exactly what is what?

[FIX] In call echo and noise from top mic pocophone

If you are in a call and the other person hears himself or noises when the top mic is touched, by hair or hat..., you can try this:
[ROOT needed]
Edit this file:
\vendor\etc\mixer_paths_overlay_static.xml
find this sections:
<!-- Dual MIC devices -->
<path name="handset-dmic-endfire">
<ctl name="AIF1_CAP Mixer SLIM TX7" value="1" />
<ctl name="AIF1_CAP Mixer SLIM TX8" value="1" />
<ctl name="CDC_IF TX7 MUX" value="DEC7" />
<ctl name="ADC MUX7" value="AMIC" />
<ctl name="AMIC MUX7" value="ADC3" />
<ctl name="CDC_IF TX8 MUX" value="DEC8" />
<ctl name="ADC MUX8" value="AMIC" />

<ctl name="SLIM_0_TX Channels" value="Two" />
</path>
<path name="speaker-dmic-endfire">

<ctl name="AIF1_CAP Mixer SLIM TX8" value="1" />
<ctl name="CDC_IF TX7 MUX" value="DEC7" />
<ctl name="ADC MUX7" value="AMIC" />
<ctl name="AMIC MUX7" value="ADC3" />

<ctl name="ADC MUX8" value="AMIC" />
<ctl name="AMIC MUX8" value="ADC1" />
<ctl name="SLIM_0_TX Channels" value="Two" />
</path>
and add this lines, so they look like this:
<!-- Dual MIC devices -->
<path name="handset-dmic-endfire">
<ctl name="DEC8 Volume" value="0" />
<ctl name="DEC7 Volume" value="92" />

<ctl name="AMIC MUX8" value="ADC1" />
<ctl name="SLIM_0_TX Channels" value="Two" />
</path>
This will set top mic sensitivity to 0, noise cancellation will not work but you can adjust "<ctl name="DEC8 Volume" value="0" />" as needed to have a little noise cancellation, default is 84. I've set it to 0 and i find it very good, no complains about the sound quality.
Also I've set 92 as the sensitivity for the lower mic, and it helps a little. Adjust <ctl name="DEC7 Volume" value="92" /> as you wish, default is 84.
I don't know if this is the best solution, but it helped me, so I share
* to make changes to this file, you need to mount vendor and system in twrp (in twrp>mount>check both)
** please report this bug using Settings > Feedback > and check "Issue" and describe the problem you are having, hopping that Poco devs will look into it.
*** I've built a magisk module to apply this fix, it makes it easier for those who flash roms frequently.
Heyy @wizard8400 i have one other problem, the mic doesn't work in calls on speakerphone but works well with normal. Do you know the fix for this?? I've tried both miui and other custom roms and have same issue.
@ayush.gl I don't think I can help, but for starts you can test if is a hardware problem: go to CIT (tap a few times on kernel version) and test main mic and top mic, I think you need headphones(simple ones, without mic on them) . From what I have tested it seems that on speaker it uses the top mic, in normal call it uses both mics, mainly the bottom one and the top one is for ANC.

hi....thanks for the fix...was plagued with this issue for a while...quick question...this is safe correct? also if i still want noise cancellation instead of setting it to 0 i can set it to like 60 so it wouldn't be so sensitive? thanks

I have tested the mic, it shows passed. Mic also works with recorder, cam, whatsapp calls. Only for calls on speakerphone it doesn't work. Any suggestions

Hey guys, i'm rooted and copied the overlay file to a different location and edited it with es datei explorer, but when i try to copy it back to vendor etc it always says vendor write only and i get a error. What to do to make it writeable. Permission is granted for the datei explorer.....dunno what to do. Have this echo and its really annoying for the peoe i call
Edit: solved it by mounting vendor in recovery and copying my modified file into vendor/etc folder
I'm having the same issue, even at low volume. But I can't find the file specified. Do I have another issue?
@Zundrium
I don't know what ROM you have, I'm on xiaomi.eu latest beta(weekly). You have root and mounted system and vendor in twrp, right?
Please help me I do not know how to do it please help me thanks
@calandula
what you don't know, how to edit the file, how to root? If one of those, then you need to search or open a topic about that operation, else will talk off topic and is not a good practice to be offtopic on a forum. ex.: I can't explain here how to root pocophone f1, there is already a topic about this.

If one of those, then you need to search or open a topic about that operation, else will talk off topic and is not a good practice to be offtopic on a forum. ex.: I can't explain here how to root pocophone f1, there is already a topic about this.

I don't know what ROM you have, I'm on xiaomi.eu latest beta(weekly). You have root and mounted system and vendor in twrp, right?

I used LineageOS and PixelExperience, both have the same issue, when rolling back to beryllium_global_images_V10.2.2.0.PEJMIXM I experience no issues.
I can also confirm that this isn't a firmware issue, I installed fw_beryllium_miui_POCOF1Global_V10.2.2.0.PEJMIXM in all cases.

Have done the same tests and getting the same results. Seems to be OS related and not firmware.
Cool you made a magisk module! If install it is it permanent? Or when i remove it it gos back to normal?
@Mooatreides magisk module is systemless, you can enable / disable this fix to apply/revert the file. After flashing a new version of the ROM and magisk, this fix is applied, or not depending by the state of the module.
