[Q] [Stock] Volume mixer_paths.xml Settings

Can someone who has not modded there volume mixer_paths.xml file located in root/etc please tell me the values. If you open the file with root explorer and look and post your settings or upload the file for me please, I would like to go back to stock or know at least mine is stock. It will be about a 1/4 way down on the file mixer_paths file, when you open it up and should look like this below. I am looking for the values. I would really appreciate the help. :highfive:
It will look just like this I just need to know what the values are.

(Guide)(How To) (Lollipop Volume Increase All Varient's)

What's up everybody. This time I bring you a simple mod to increase the volume's on lollipop. What we're going to do is make some edit's in the mixer_paths.xml located in system/etc. Open in Notepad++ or editor of your choice and search for <path name="handset"> . See below for area's to edit,be careful and adjust slowly. Set permissions to 644 or rw-r-r.
Lollipop Guide: Location =system/etc
Only increase levels by a maximum of +10 to avoid speaker damage. On HPHL & HPHR raise levels slowly to avoid damage or distortion.

Fixed lollipop guide and added kitkat,.... Please post your xml when finished so we can share them with everyone. You can also post your stock and I'll update it and post it.Thanks.....

Thank you for this post! I have been looking for a while for a way to enhance the quality of my Bluetooth Headphones (Noise Cancelling Philips SHB8850NC). At the beginning I tried to install Viper4Android on my Samsung S5, but I was not able to make it work because I have the Android Lollipop 5.0 with Knox installed. So the only solution was to manually increase all the gains of the mixer_paths.xml file as described here, and now I can enjoy the best Bluetooth Experience! The bass is now pretty deep with the built-in Samsung player (bass equalizer).

Call mic gain in mixer_paths.xml
I read with great interest "How to increase volume in Lollipop Samsung S5". In my S5 the sensitivity of the call microphone is low: I need to speak with very loud voice.
I have not found in the Italian Forums a way to boost the sensitivity. I would appreciate if you could explain to me what I must variations in file mixer_paths.xml to achieve the required purpose.
I would ask you to be very clear how my experience is limited. If a slight increase in sharp ones the possibility exist too. My S5 SM-G900FD is rooted. Thank you.

Does this work with the exynos version?
I am asking because I use an S5 neo but the mixer_path.xml content is different from this one.

Does this work with g900f?

Stereo Sound MOD for G5 [root]

This file enables earpiece speaker to have stereo sound. And overall it sounds a lot better than original configuration.
Tested only with H850 and H830, do it at your own risk!
You'll need some file manager, I'm using Total Commander in this example. First, go to /system/etc and backup your mixer_paths_tasha.xml file, (it will ask to give root permissions to do that), then delete it.
Paste new file into system/etc and change permissions to 644
Reboot and enjoy stereo!
Download V1.1 for stock
mixer_paths.xml v1.1 for CM 13 -credtis to @nima0003
mixer_paths.xml v1.1 for CM 14.1 -credtis to @nima0003
CM14.1 instructions by @nima0003:
1. Remove mixer_paths_tasha.xml from the etc folder
2. Paste the mixer_paths.xml file (don't worry about the name)
3. Set permissions
4. Reboot
Revert back
If you want to test out with different G5 version, download this file and do the same steps (you may need to rename the file to match your mixer_paths file name) and report if it does work on your model.

Man this is awesome . Works perfectly on my H850.

OK, in order to make it work with CM 13 I had to modify a few things, otherwise it would give no audio. Do you want to post it in the OP or do you want me to make a new thread?

Works perfectly thanks a lot makes it sound a lot better biggest question is lets hope it cannot cause no damage to the earpiece speaker
Great work

works well

So awesome, thank you very much hope this will be incorporated in to muistones patch and the other roms

works perfect with AICP ??
gesendet von meinem LG G5 H850 AICP11.0

Thanks it work perfectly

Just gave it a quick test yesterday. Seems to work very well! Usually use headphones most of the time though and just restored my backup. Just a quick heads up incase it happens to anyone else. After I restored the file I couldn't play videos at all. Kept getting errors in youtube and netflix and such. Needed to change the permissions of the file after restore aswell. Working fine now

amazing sound is like a HTC10 now,I wait this for a time,but now is perfect!

Works great! :laugh:

if any interested, here the patch what all modified (CM13 only)

[Q] Volume Boost?

I'm guessing you boost the volume by modifying mixer_paths_tasha.xml file. I've tried the usual suspects below already with no effect:
1) initial mixer settings
Code:
<ctl name="HPHL Volume" value="25" />
<ctl name="HPHR Volume" value="25" />
<ctl name="RX0 Digital Volume" value="94" />
<ctl name="RX1 Digital Volume" value="94" />
<ctl name="RX2 Digital Volume" value="94" />
<ctl name="RX3 Digital Volume" value="94" />
<ctl name="RX4 Digital Volume" value="94" />
<ctl name="RX5 Digital Volume" value="95" />
<ctl name="RX6 Digital Volume" value="95" />
<ctl name="RX7 Digital Volume" value="94" />
<ctl name="RX8 Digital Volume" value="94" />
and 2) headphones
Code:
<path name="headphones-44.1">
<ctl name="SLIM RX3 MUX" value="AIF3_PB" />
<ctl name="SLIM RX4 MUX" value="AIF3_PB" />
<ctl name="SLIM_5_RX Channels" value="Two" />
<!-- [email protected],2016/4/7,use 24bits to get rid of 16bits innate noise -->

<ctl name="RX INT1_1 MIX1 INP0" value="RX3" />
<ctl name="RX INT2_1 MIX1 INP1" value="RX4" />
<ctl name="RX INT1 DEM MUX" value="CLSH_DSM_OUT" />

Mic Problem Low Recording Volume

I just own Mi a2, bought it second hand from other people.
Atm i'm using Pixel Experience ROM.
My proboek is about Low Recording Volume.
I tried to record my voice via whatsapp audio recording and 3rd party app recording, but the result is a low volume voice recorded.
I was using stock ROM with magisk installed and Quickswitch module installed. I noticed low volume recording sound so i thought it was because the rom and then i flashed PE, but the problem still remain.
The funny thing is, if i record a video through stock camera app or through instagram story, the sound does recorded properly, not low voice volume.
Anyone know how to fix this? Do Mi A2 have two mic, since video recording can record voice good, but calling or recording the volume is too low? Thank you for your answer.

For me its hardware related. I take it to service center and they clean the mic, the problem solved.

I don't think mine is hardware related. It doesn't happen when i use Easy Voice Recorder app, it happens when I use stock camera app to record.

i have same issue, anyone has fix for this?

Introducion
Same problem here: Mi A2 on Pixel Experience, but I had problems also with the stock version.
Since I've got the root and I remember that with my Nexus 5 (old good times) I had the possibility to change gain in kernel settings. Here, I cannot.
Then I remembered that I also heard about mixer_paths.xml file, that if changed, can change the gain of speakers and microphone. Since I'm not able to identify what parameter should I change/increase, I went to Google and searched for some infos. Unfortunately, every device has "its own" mixer_paths.xml, and it changes.
I found for example a guide for Nexus 4 here and something with Samsung S5 here.
How to
Important:
Before ANY modification, keep TWO copies of your mixer_paths.xml original file. Two because I was stupid and I lost my first one, and the second was already broken ¯\_(ツ)_/¯
I'm not responsible for any loss and damage, nor hardware nor software related.
Remember to save the mixer_paths.xml file with EXACT SAME PERMISSIONS as it has before modification. Since, again, I'm stupid, it has the 0777 permission (all checked in FX File Explorer)
Tested only on Pixel Experience QQ1B.200105.004 on Mi A2, 64+4GB
Experimenting here and there, I found that increasing some values effectively changes my gain, but I'm not sure why and what precisely. Gain works great on IM, like Telegram, but I'm still not great (but better) on camera videos.

I attached also my current mixer_paths_8.xml - just rename it and remove that "_8" if you want to use it as-is.

My voice recordings were very bad when player back in the recorder app. The problem solved by this method:
• in the Recorder app, go to settings (the gear/wheel).
• disable "use receiver to play audio"
• done.

I just formatted my phone and switched from CRDroid to Lineage OS. The mixer_paths.xml file is somehow different, but I manage to fix it out.
To fix low microphone on Mi A2 on CRDroid just use my comment above.
