[GUIDE] Volume boost.

So I got the G Pro 2 (D838) about three days back. Outstanding phone but the volume output was lower than I'd have liked it to be. Editing the snd_soc_msm_Taiko file like the G2 didn't do much. Downloaded the Viper audio app (good stuff, but couldn't increase the volume gain much). And then I stumbled on this thread of the G3 which did the trick: http://forum.xda-developers.com/lg-g3/general/guide-headphone-speaker-volume-booster-t2819821
REQUIREMENTS:
1. Root
2. File Manager with Root Access (ES would do)
3. Text Editor (ES would do again; but if you're more comfortable copying the file to PC, something like Notepad++ would do)
STEPS:
1. In the root explorer, go to /system/etc and find "mixer_paths.xml". This is the file you need to edit. As mentioned, you can either do it on the phone using text editor, or copy to the PC and carry out changes there. Backup this file someplace before doing anything.
2. Find the following values and change it (as per your requirement). The below values have been modified to my current setting, and is crazy loud. My ears can only manage levels around 70-80%. So choose to increase values wisely:
Code:
[COLOR="SeaGreen"]<ctl name="RX1 Digital Volume" value="76" />
<ctl name="RX2 Digital Volume" value="76" />[/COLOR]
<path name="speaker">
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="One" />
<ctl name="RX7 MIX1 INP1" value="RX1" />

3. IMPORTANT- Once complete, make sure the permissions are set to rw- r-- r--. This step is extremely important or you'd probably end up soft bricking your phone.
4. Reboot your phone and blow your head off.
DISCLAIMER: Not responsible if you bricked your phone, killed your headphone due to crazy increases, killed the neighbor, swallowed your phone, etc.
ALWAYS BACKUP BEFORE ANYTHING. Set permissions correctly and you'd be fine. Report back with ROM/ model no, and what not if this doesn't work.
PS. The Viper4android app does work after this; confirmed.

What editor did you use for changing values? Did you reset permissions before reboot?

Thanks
Thanks man. I am testing it right now.

How to Fix Low Call Volume & Low Microphone issue with OnePlus One

So, I bought a used OnePlus One last week and the problem I was facing, very low call volume and microphone volume. The opposite person could barely hear me. So I started to Google and found some fixes. But nothing fixed them completely. So I got the real & complete fix.
Should be mentioned, I had the problem on the latest stable Cyanogen OS -YOG7DAO1K6 and this fix, actually fixed the issue.
A phone is firstly a communicating device. If you cannot do calls properly, what’s the purpose of a phone? So, you’ve got a OnePlus One and some of you might have tried different fixes. But still not satisfied with the mic quality of OnePlus One. So what’s the fix?
The solution I came into, took quite a few hours. Just when I was about to quit, feeling dissatisfied with the overall mic quality, I found the solution. This is a 4 Step Solution so you’ve to be patient.
Step 1
You need to have root. Rooting is very easy. Install TWRP, flash SuperSU & you’ve got root. No problem. The tricky part starts here. After rooting downlaod ES File Explorer and turn on root access.
Step 2
Navigate to this file: /system/build.prop
Open with any editor and search for a line that says
ro.qc.sdk.audio.fluencetype=fluence
Change it to
Code:
ro.qc.sdk.audio.fluencetype=[B]none[/B]
Step 3
Now go to /system/etc/audio_platform_info.xml & open it using an editor. Try to find the line SND_DEVICE_IN_HANDSET_MIC and change it like this (Replace 40 with 4)
Code:
...
<device name="SND_DEVICE_OUT_VOICE_HANDSET" acdb_id="7" />
<device name="SND_DEVICE_OUT_VOICE_SPEAKER" acdb_id="15" />
<device name="SND_DEVICE_OUT_VOICE_HEADPHONES" acdb_id="10" />
[B]<device name="SND_DEVICE_IN40_HANDSET_MIC" acdb_id="4" />[/B]
<device name="SND_DEVICE_IN_SPEAKER_MIC" acdb_id="42" />
<device name="SND_DEVICE_IN_HEADSET_MIC" acdb_id="8" />
...​
Step 4
File /system/etc/mixer_paths.xml and try to find ctl name=”DEC4 Volume” within the context (scroll few times because it’s kind of on the bottom part of the file) and replace 84 with 92/94/95 (the greater, the louder)
Code:
<path name=”main-mic”>
<ctl name=”AIF1_CAP Mixer SLIM TX7″ value=”1″/>
<ctl name=”SLIM TX7 MUX” value=”DEC4″ />
<ctl name=”DEC4 MUX” value=”ADC3″ />
[B]<ctl name=”DEC4 Volume” value=”92″ />​[/B]
Step 5 (Optional)
This is an optional fix. If you feel your in call volume (the level of sound you hear when the other person talk) is low than you expect & you want to increase it a bit, download & flash the in call volume booster zip from XDA
This should increase the in-call volume.
Step 6 (Optional)
You should clean up the microphone area with a blower to make sure there’s no physical blockage.
Caution
You need to apply the same tricks again if you update or flash your current ROM.

Great!
Hey!
Great, i just wanted to create a topic about this and found this topic.
So i have digged out a bit different solution, some might find this useful too:
blog.kopiascsaba.hu/2016/06/fix-one-plus-one-a0001-low-speaker.html
(Can't post link jet...)
But now i will check out your solution too.

Hey! I think SND_DEVICE_IN40_HANDSET_MIC is a typo, it is SND_DEVICE_IN_HANDSET_MIC originally! Correct me if i'm wrong!

I did steps 1,2,3 but am unable to do step 4 as my code is a little different. My mic works now but it's quiet. I messed with changing the other volume values and it made it worse. My code is below.

Sound Mod. Turn your galaxy note 3 into a stereo dual speaker phone!

Sorry, I deleted how to do this, because apparently it was stepping on someone's toes by not asking or giving credit. I just figured out how to pull one of the features out of a rom I liked, because it works well as a stand alone "app" or "mod", and thought people would enjoy it. I wasn't aware of the copyrights and ownership of ideas on here. So the person who deserves all the credit and praise has posted it somewhere on these forums, I'm sure you can find it. I wasn't aware of that when I posted mine, so my apologies to them. Just make sure if you post something useful to people, search through xda, and try to find the people or person that originally created the seeds for that idea, and ask them if it's ok to post what you intend to, and most importantly, make sure you give them credit and praise. Developers are very protective and proud of their work, so before posting anything, make sure that you ask, praise, and reassure everyone where you got it from, so they and others will also give them many praise and respect. No matter how small the mod you are posting, or helpful, or even insignificant, please follow the rules.

We have this post is it the same .

Sry

No i suggest just asking the mods to merge posts if they think suitable or leave yours as is .

can I install the mod on another phone ?

I would like change balance - is any app, when i can do it ? (fust for speakers, not for headphones)

Refer all questions to original developer.

Here is the same mod, edited so that it works with LineageOS 14.1 (SM-N9005 LTE Int).
Here are the changes from the original file from the rom.
Code:
<path name="spk">
<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="RX1 MIX1 INP1" value="RX1" />
<!--<ctl name="RX1 MIX1 INP2" value="RX2" />-->
<ctl name="RX7 MIX1 INP1" value="RX1" />
<ctl name="RX7 MIX1 INP2" value="RX2" />
<ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX1" />
<ctl name="HPHL DAC Switch" value="1" />
<ctl name="DAC1 Switch" value="1" />
</path>
INP1 (left channel) goes to RX1 (ear speaker)
INP2 (right channel) doesn't to RX1 (ear speaker) [because it's commented out]
INP1 (left channel) goes to RX7 (big speaker)
INP2 (right channel) goes to RX7 (big speaker)
you can set these as you like, I found that this way, I get maximum volume, while retaining the stereo effect.
The next important lines are within Play Scenario
Code:
<path name="speaker">
<path name="spk" />
<ctl name="SPK Status" value="1" />
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
<ctl name="EAR PA Gain" value="POS_6_DB" />
<ctl name="RX1 Digital Volume" value="86" />
<ctl name="RX7 Digital Volume" value="74" />
<ctl name="SPK DRV Volume" value="8" />
<ctl name="COMP0 Switch" value="1" />
</path>
HPHL Volume, HPHR Volume and EAR PA Gain are needed so that Ear speaker starts working (I didn't hear a difference when changing EAR PA Gain to POS_3_DB, but let's say this is louder - also this setting is being used by the phone when you click extra volume in the stock rom during calling with speaker).
RX1 and RX7 set the volumes (0-100) for the Ear speaker and Big speaker, accordingly.
HOWTO:
Copy mixer_paths.xml to /etc, (backup the original), and set permissions to -rw-r--r-- (as all other permissions in the folder).

After a week using i found bug, not working when using internet call like whatsapp. So i revert to original.

The sound of caller is verrryyy LOUD so people around me can hear my conversation!!!

How I can make lower speaker on phone call?
When I receive a phone call, the sound of caller people is veryyyyyyyy LOUD as much as my around people (with 6m distance) can hear sound of caller :'( also my ear pain :'(
My device is root,magisk,xposed
Thank you for your help.

Simply by pressing the volume down button during call will lower the volume of the ear piece.

thank you for your answer, but I've enough experience about "pressing the volume down button during call"
the sound is verrryyyy LOUD even the call volume is on minimum :'(
I guess, it's related a value in a .conf or .xml file in android system .

Is this question HARD? any answer?!

I guess you can edit the xml if its related which is mixer_paths.xml if im not mistaken

thank you so much for your reply, but which param is related to "sound of caller" volume?!

What is valid value range? is the 80 minimum? can I set it to 40?!

How to remove hissing sound at low volumes Galaxy tab 4 [root]

Bought so many different headphones to only be dissatisfied with that static noise.Recently found out a fix gets rid of the problem.
•Before you begin make sure you have root and file explorer (I used es file explorer).
1. In the file explorer go to /etc and find mixer_paths.xml ,make a backup of the file just in case.
2. Open mixer_paths.xml
3. Find:
