Guys, I have a redmi note 4g (snap 400, 2gb ram, miui v6 Kitkat).
Having some problems with volume (headphones, mainly - speaker is solved) being a tad bit low.
What ive done to cure it a bit:
edit mixer_path.xml (editing thr rx1 and rx2 volumes)
it increases the headphone volume - problem is distortion occurs
the lines that are involved
changed rx1 and rx2 to 90
Code:
<path name="headphones">
<path name="headphones-lite" />
<ctl name="COMP1 Switch" value="1" />
<ctl name="RX1 Digital Volume" value="81" />
<ctl name="RX2 Digital Volume" value="81" />
</path>
what ive done but didnt work at all:
1. edit the the files inside the system/etc/snd_soc_msm
the 3 files:
snd_soc_msm_Tapan
snd_soc_msm_Tapan_SKUF
snd_soc_msm_TapanLite
(tried out editing these files because it worked on some other devices)
lines involved
(increased rx1 and rx2, hphl and hphr values)
Code:
SectionDevice
Name "Headphones"
Comment "Headset Rx device"

'SLIM RX1 MUX':0:AIF1_PB
'SLIM RX2 MUX':0:AIF1_PB

EndSequence
ACDBID 10:1
EffectsMixerCTL "SRS TruMedia"
EC_REF_RXMixerCTL "SLIM_RX"
EndSection
2. edit the HPHL values in mixer_path.xml file
no effect. It used to work on my moto g gen 1 on kitkat
lines involved
Code:
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
I'll attach my mixer_path file and those 3 other files. I would really appreciate if you guys could have a look and help me out.

Hi, is there something mod to increase the volume of this tab? Ive switch on the xloud bout, i dont hear much difference I'm root.

You could do it by yourself by editing the file "/system/etc/mixer_path.xml". After edit you might need to set file permission to 0644 and clear dalvik cache in recovery. Make backup of your original file though.

Depending what you want? Speakers or headphones. If I remember correctly these lines are for headphones:
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
And again if I remember correctly speakers are these lines:
<ctl name="RX1 Digital Volume" value="84" />
<ctl name="RX2 Digital Volume" value="84" />
<ctl name="RX3 Digital Volume" value="84" />
<ctl name="RX4 Digital Volume" value="84" />
<ctl name="RX5 Digital Volume" value="84" />
<ctl name="RX6 Digital Volume" value="84" />
<ctl name="RX7 Digital Volume" value="84" />
RX1 and RX7 are perhaps those that make differences but try yourself.
Remember to be careful because one can easily damage the hardware if increasing more than speakers can handle.

Do you have any other mods? Only differencies with your mixer_paths are that you have increased "RX1" from 82 to 100, RX2 from 82 to 100 and original file have "</mixer>" this line in the end of the file without quotes.
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 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.

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

Hey guys, I'm working on a headphone jack volume boosting magisk mod, and I'm trying to figure out which value corresponds to the headphone jack. On other phones, things were more obviously labelled, but I can't seem to figure this one out. I've attached the stock 'mixer_paths.xml' file to look through.
I'd really appreciate any help and insight you all may have.
To me lack of conformity with the volume of the headphones, I modified these lines I noticed a reasonable increase. <path name="headphones">

<ctl name="HPOUT1R Input 1" value="ISRC2INT2"/>

How did you save the file may I ask since it's read only even with superuser?

I can edit the '/vendor/etc/mixer_paths.xml' with no problems with root access. I don't know what you are talking about.

Same, I'm on Lineage OS 16, on the Moto X4. Using Magisk, I can get root access, and edit the file just fine. And now, the edits are persistent across updates, so I don't really need to develop this mod anymore.
