Ok folks, as you know, the headphone volume could use a little higher output than we have right now. Especially for those of us "rockers"!
So, this little edit will increase the volume to a more desired level. Thanks to ZeroInfinity for the conversation.
Warning! I'm not responsible if you blast your eardrums out, or damage your headphones/earbuds. You do this at your own risk.
That said, your tab should have the following.
A. Rooted
B. /system write privileges
C. A good file explorer (ES File Explorer for example)
Open your file explorer and go to the following folder: /System/etc
Find the file "nvaudio_conf.xml
Open in the built in editor
Scroll down the file about 70 or so lines and you will see the following section;
Code:
<path>
<!-- playback paths-->
<ctl name="DRC Switch" val="1"/>
<ctl name="HPF Mode" val="Hi-fi"/>
<ctl name="Speaker Volume" val="0x39"/>
<ctl name="Headphone Volume" val="0x30"/>
<!-- capture paths-->
<ctl name="Left Input PGA Volume" val="0x1C"/>
<ctl name="Right Input PGA Volume" val="0x1C"/>
</path>
Gee, what's that???
<ctl name="Headphone Volume" val="0x30"/>
Here's the hard part.
Change that 0x30 to a 0x36
This relates to a value from 48 to a new 54.
Save your file, close your file explorer, and reboot.
Blast your eardrums out! :laugh::laugh::laugh:
You can also do this with the external speakers, but I'd be careful with them. Acer isn't known for using quality speakers
EDIT: Use this chart for a Hexdecimal conversion
Cheers!
(don't forget the Thanks button).
Way cool!!!!!
Awesome, MD!
I think we could the volume of the external speakers as well, like you said, but only for a small percentage.

You should be able to. Note you will probably have to tweak each ext speaker setting in the file. Seems there are multiple entries depending on app.
I would advise only increasing by 1 step though and see how it behaves. I've seen speakers go bad on the 50x tabs on a normal basis!
Also, if you're running my de-odexed rom, or have de-odexed your STOCK rom, I have a 30 step volume mode that really helps. Stock setting is 15 steps.
Thanks for tuto. I changed speakers to 0x42 and after reboot the audio stopped (only for speakers) so i changed to 0x39 again.
I try with playerpro, basic media, streaming audio.... and nothing audio One fue speakers

Probably Acer has a limiter in one of the config files. Will have to take a look.
yeah, up to eleven! \m/
For those that just want more headphone volume without the hassle of installing Viper4Android, this is an easy mod that takes literally a minute. The stock S7 (and edge) headphone volume output is very low, especially if you are trying to power larger studio type headphones.
1: Root your device (I used the Chainfire method)
2: You must have a file explorer with root folder access (I used Solid Explorer)
3: Navigate to System > Etc > mixer_gains.xml
4: Important .... take a backup or copy of mixer_gains.xml in case something gets screwed up or you wish to go back to stock volume in the future
5: Edit the following lines in the file under <path name="gain-media-headset"> as below (note, I have changed these values from the original post as these work better)
<ctl name="HPOUT1L Impedance Volume" value="110" />
<ctl name="HPOUT1R Impedance Volume" value="110" />
<ctl name="HPOUT1L Input 1 Volume" value="95" />
<ctl name="HPOUT1R Input 1 Volume" value="95" />
6: Save file and reboot.
This significantly increases headphone output without distortion, although if you do push it too high it will naturally overload the DAC. You can decrease the numbers in the lines above if you think it is too loud. I have tested this on Poweramp, MX Video Player and Spotify and it works perfectly. This does not affect the operation of system EQ's like sound alive.
Please leave thanks if you found this useful to you.

works great with poweramp, thanks for the this!!

This is purely for the headphone volume. The other one changes many other settings as well and you have to push it with TWRP. This can be done with root only.
The XML files from ZuBi's thread can be extacted and copied in the same way. No need for TWRP.
Be careful with that. I tried exactly the same thing. Device wouldn't boot and was stuck on Samsung logo.
Had to flash the unmodified files with TWRP to get the device back.

When you extract the files and copy is necessary to change the permissions or you have this problem.
Do you edit the files in the phone or on the computer? Which program are you using to edit the XML files directly in the phone?
As stated above, I used Solid Explorer text editor on the phone, although any text editor will work. You can also copy the file to your PC, modify there then put back to the phone.
Just make sure the permissions are the same for the returned file or the device won't boot. They should be -rw-r-r

Great info. However I'd like to add a bit of further information:
1) For easy reference, the default values on my phone are 105,105,32,32.
2) The second pair of numbers ("Input 1 Volume") appear to be the digital volume control, i.e. sets the output level of the DAC. It accepts values up to 95. Any value above 95 is ignored and treated as 1. The settings appear to be linear (i.e. 64 is twice as loud as 32).
3) The first pair of numbers ("Impedance Volume") appear to be the analogue gain control, i.e. sets the analogue amplification applied after the DAC output. The values are highly non-linear (115 is more than twice as loud as 105).
4) Adjusting the digital control (Input 1 volume) does not cause any appreciable change in distortion or noise and I would recommend increasing this to maximum (95)
5) Adjusting the analogue control (Impedance volume) drastically increases noise, background hiss, and distortion. Even increasing this a tiny bit (e.g. from 105 to 108) causes there to be a constantly audible background hiss. I would recommend against changing this at all if it can be avoided, unless you have particularly insensitive cans.
Personally, mine's set to 105,105,95,95. That's just below the level needed to max out the DAC and the analogue amp, without the huge increase in noise you get from the 120 setting in the OP.
Wish I knew how to do it
it works well on my phone no problem I edit everything correctly

on the phone use Soild Explorer and set 95,95,80,80 that works for me great great
So what are the values to enable dual speakers?
It seems not everyone is aware of the "High Impedance" mode for the DAC.
It's the best mode and the audio quality seems to be the best.
You can only trigger it with connecting high impedance headphones,
Or, like many here do, hassle your way with cables to trick it into this mode
(For example - i use extension cable+audio technica anc33is = triggers "High Impedance" mode).
Personally i think it is absurd to go through all those tricks just to get good audio quality.
I guess it exist to prevent headphone damage / battery),
But really, i'd like to get the full power from the audio chip, because that's what i bought, without traveling with tons of cables.
Now for the actual stuff:
Any ideas how to remove the software limit and force it into "high impedance" always?
Perhaps some *.prop file, or..? How would you approach this.
In fact @HocqpepaTy has provided a method to triggers "High Impedance" mode without external cables in the DAC-Fix thread.
1. You need root on your phone
2. Using a root explorer, mount R/W and navigate to system/etc
3. Go to /system/etc/mixer-paths.xml (remember to backup it first)
4. Find this part of code, change the value of "headphones-hifi-dac" from "31" to "13" to make normal mode same as AUX mode, also, "0" for High Impedance Mode
Code:
<path name="headphones-hifi-dac">
<ctl name="Es9018 Master Volume" value="31" />
</path>
<path name="headphones-hifi-dac-advanced">
<ctl name="Es9018 Master Volume" value="0" />
</path>
<path name="headphones-hifi-dac-aux">
<ctl name="Es9018 Master Volume" value="13" />
</path>
5. Change permissions of mixer-paths.xml to 0644. (rw-r-r)
6. Reboot.
PS: After reboot, it will not change the text, still showing "normal audio device", but the changes in sound is noticeable.

Found a way to change analog gain value without having to mess around with editing Mixer_paths.xml and what not.
Assuming you're rooted download ALSAMixer from Google Play install ALSA from in the app and make sure you select alsa_amixer controls as your Mode in settings in the ALSAMixer App.
After that search for Es9018 Master Volume and change the value to anything from 0 to 80. 0 being max volume like High Impedance mode is set to.
This isn't permanent and will reset on restart but it's nice to be able to change analog volume on the fly.
Thanks to ivangundampc for this trick.
Thanks also to KosanRio for the alsamixer tweak. I'm curious if the end result is the same (with a '0' value in alsamixer or in /system/etc/mixer-paths.xml)...

It is I believe, plugging in Aux/High-impedance headphones/normal headphones will all give you the exact same value in AlsaMixer as it does in Mixer_paths.xml
finally a superb sound out of the box
:good:
I'm relieved not to have to use an adapter cable with the V10 anymore !
Edit, nevermind.

I ran into this blog struggling with trying to get more gain out of my V10. I'm on MM and rooted. I currently do not hear the quick silence switching between HiFi ESS DAC and back to the SoC DAC. I previously had a V10 that was on LP and I could hear the serious difference. The only output I can get out of my phone is the SoC.
In regards to this mixer paths edit, does the lower number (in this case 13) change the audio gain to output more voltage? Also, you state "0" for high impedence mode. Am I supposed to change the 0 to 13 as well?
I really wish I could understand this more. I have V4A installed and running without issues - which I did in the past on LP. Now I'm just baffled I can't figure out what's going on.
Thanks in advance!

Someone correct me if I'm wrong but I think 0 is for high gain mode. 13 is for Aux mode.
If you don't want to mess with xml you can download the alsa app and play with that a bit.
Head over to head-fi.org there are more forum posts on getting best sound out of the V10.

Thanks for the reply! I tried out the Alsa app, but when I select the controls (not scontrols) nothing appears in the list. Not sure what I'm doing wrong? I granted it root access. The error I get is: "error: only position independent executables (PIE) are supported."
I think there's something wrong with the ROM in general. This is complete stock with only root. Previously I could tell when the DAC was enabled by a short period of silence, and the volume would then be reduced. Also, when the volume was at 0 it was at the far left and would go all the way to the right as "max", and when it's on it would start at 0 at the far left, then only go to 75 (which is the DAC's max volume setting).
The confusion here is I can't get any difference in sound no matter what I do. Even if I trick the DAC into aux mode, nothing changes. Trying to adjust the balance in the HiFi settings page does nothing.
When I had LP installed, it worked PERFECT. I used the DAC only on flac files when I was home sitting in my chair, and would leave the DAC off for mp3's and Spotify while traveling because the volume would go higher to overcome the aircraft noise.

Yeah does seem rom related with the error from alsa and nothing happening. Like its not getting enabled. Since your rooted, can you make a twrp backup, then do a factory reset and see if that does anything.
You could also try flashing the two roms available for the device. I'm like you, stock rooted. But I'd probably make a backup and try Andy's rom just to see if it's software related.

Thanks for all this. Worked like a charm. No more bs with extension wires. I swear it sounds even louder and cleaner with just the headphones plugged in without the extension cable.
Just curious. Has anyone tried any other value, like 12 or 14. Why 13?
Hi,
My V10 not recognized the high impedence ear Phone.
The only way is modify The values on System file?

Hi all.
I'm using CM13 SultanXDA ROM (latest build).
The in-call volume is low and I can barely hear the other side. What should I edit in mixer_path.xml file, or any other file to increase the volume?
Thanks!
Edit the file in /system/etc/mixer_paths.xml
Around the line 571 you will find
Code:
<!-- Analog output devices -->
<path name="ear">
you are in the right section, so in the same section around the line 576 you will find:
Code:
<ctl name="RX1 Digital Volume" value="84">
Change the value (84) to an higher number I tried 100 and it's very loud, It think 92/95 could be enough.
Thanks.
I now seem to be having another issue.
When on speaker mode, the other side cannot hear me... WTF?
Oh, that never happened to me.
Did you change the fluence type to "none"in build.prop?
yes I did.
not really helpful
This mini guide is for users who want to modify the ear/handset speaker volume for their Xiaomi Mi A1.
* You need to open one of the following files with root permissions:
(For STOCK) "root"\system_root\system\vendor\etc\mixer_paths_mtp_global.xml
(For CUSTOM) "root"\system\vendor\etc\mixer_paths_mtp.xml
* Find <path name="handset"> (Hint: It's near the bottom). Modify <ctl name="RX1 Digital Volume" value="88" /> for a value closer to 100 to increase the volume (92 works fine for me) or lower that number if the ear speaker is too loud for you.
* You can also modify the "Digital Gain" value within <path name="speaker"> if you want a louder bottom speaker. In my case the default is 56 and I increased it to 64.
* Save without changing the format (UTF-8 if the editor ask), and reboot.
Tested on two Xiaomi Mi A1 under STOCK 8.1 and Lineage OS 15.1, using Magisk Manager 16 (for root access), and Hootan Parsa's MIXplorer.
Best regards. [Sorry for my bad English]
Thank you
It works
Mine was set to 83 and I felt it too low and increased to 108. It's Really loud. Will scale it down

I don't think you can apply this fix without rooting, and rooting is probably the best thing you can do anyway; I can't stand a smartphone without ad-blocking, for starters.
i changed the value to 92 and rebooted and still no change in the call volume so i changed it to 99 and rebooted but still nothing and now it is 130 and nothing changed the volume is still very low
what should i do please help
it works !
it works perfect!
my value is 84, i change to 74 and the volume of the call is finally OK!!
THANK YOU VERY MUCH !!! YOU SAVE MY EAR..
:good::good::good::good::good:
I updated the post with proper instructions for Stock after I went back to it about a week ago. It was a little confusing since both files exist even after a full-format clean install but the system doesn't read the same file than LOS.
cool! can this also be done for the MIN volume? so basically how silent the first step after mute is?
Thanks ALot!
It worked as expected. it was frustrating attending calls with low earpiece volume had to keep earphones around.!!
Also
can we unroot and relock the boot-loader without affecting these changes? just like the case we do while installing google-cam and unrooting/re-locking doesn't affect camera2api or eis.
Hello, i would like to know if I apply this mod the phone will be able to receive OTA updates.
Thanks
Antonis
I can confirm OTA updates work just fine for LineageOS + MindTheGapps + SuAddon.
On the other hand, Stock + Magisk require to uninstall Magisk before OTA or it fails.
Followed the instructions, but now I have no audio at all.
Any chance to do this without root access?
Used this after my in ear volume was so soft after the July update. Turned the value up from 84 to 99 and it worked perfectly. Thank you so much this saved me a lot of money instead of getting a new phone!
