How to Boost Headphone Volume on Galaxy M20 ? - Samsung Galaxy M20 Questions & Answers

hi ,
My Galaxy M20's maximum headphone output level is low for me. I did search my phone's internal memory and i find 2 files in firmware. ''mixer_gains.xml'' and ''mixer_paths.xml''.
I think these 2 files control to audio hardware gain levels but i dont know which line in which file to must be modify ? Other Samsung models files are different. please help me.
My phone info :
Model : SM-M205F
O.S. : Android 9 Pie / Root
thx...

Try to use magisk modules if available, or tune the dolby atomos options, that one worked for me.

Galaxy M20 ' s maximum headphone output limited by samsung ( approx 800mV peak max ). i edited ''mixer_gains.xml'' file and increase headphone output volume but headphone output immediatly shutdown after first high transient output signal and switch to speaker. headphone output signal is no clipping. 1240mV peak clean output signal but its shutdown and switch to speaker. ( measured by LeCroy WS3024 digital oscilloscope )
i bought this phone 2 months ago but i didn't use it yet because only this reason. please help me.

can anyone help me ?

and i attached these 2 original files.

???

i downloaded 81 apps for headphone volume boost and i tried 38 apps yet. none work ! i think all apps blocked by samsung in new OS. samsung engineers are working for blocking unofficial apps , modes and hardware capabilities. they are no working for make a better device. stupid visual effects , stupid official apps and thats all. this is my last samsung phone ! i will never buy a samsung phone again ! approx 2 years past and i can't use this ****. ****ing garbage phone !

A20 and M20 shares the same settings for earphones so they have the same settings except for the speaker amp. I experienced audio shutdown when I increased the value in mixer_gains.xml so I gone further and realized that the audio threshold and OVP tuning value is set at mixer_paths.xml. The original OVP tuning value is 231 which is not balanced to the gain set at mixer_gains.xml and this causes the audio shut-off as it cannot pass higher than 700 to 800mV peak original set by mixer_paths.xml so I adjusted the value (thinking about the optimized non-audio IC dangerous value) and I managed to increase the maximum gain higher than expected. I tested this with multiple earphones and headphones including AKG earphones and headphones and the sound is clean. Bass is also boosted too.
I edited the xml files posted here so you can try it. I adjusted the values so all you need to do is test it. Be sure to backup the original file in case something goes wrong.
Have a good day!

thank you...thank you...thank you...
your modification is ok ! it's working ! my M20 hp output level is equivalent with my old modified S3 phone's hp output now and no clipping. now i can listen music ! thank you !
but i noticed 1 bug. if i plug a 3.5mm stereo jack-to-RCA cable to my M20's hp output ( for mixer or audio amp input ) and if i turn up volume to maximum , M20's hp out generates very high output and shutdown ! this is basicly open circuit for M20's hp output because mixers and audio amplifiers inputs has >10Kohm , >20Kohm or more higher impedance. can you solve this bug ?
lastly : can you increase volume up little bit more ? i want %10 or %15 more. if you can't do it , no problem. i can use it with this level. if you can do it , it's perfect to me.
i also added some pictures about my test conditions and results.
thank you...

In my A20 device I didn't encounter this kind of AUX bug. Maybe it has something to do with your AUX cable or RCA cable because of its resistance. Bigger wires, higher resistance. So your M20 needs to pump out much higher current in order to meet the peak requirements in the output.

1 interesting note : these phones are look like has not a normal audio amplifier for hp output. todays high power professional audio amplifiers has very high damping factor. ( not old tube amps ) this means amplifier output voltage never change when are you change load impedance. ( without rail clipping ) these phones hp outputs look like has a big serial resistor or some sensing system doing similar job. hp maximum output level is lower when you use low impedance hp and hp maximum output level is higher when you use higher impedance load or open circuit.
high damping factor is important for quality of sound. for understanding this situation need to some another tests but i didn't because I don't want to deal with anymore. i just want high volume music to my hp

This devices do have Over current, Over Voltage, Overheat protection built into their chips. Those protections have sensitive sensors. If you just want higher input from your headphones, stick to what i've edited. I tried to increase the values above 199 and it's terrible. Distortions and the sound chip/amplifier is overheating because higher voltage, higher current, more output but more heat. So I sticked to the optimized values.

ok no problemo. this volume level is ok. thanks to you, I'll be able to use my phone.
now i search a good mp3 player program ( working correctly ofc ) thx

this is interesting topic, good solution. but is it support an external DAC for SM-M205G? on the samsung community says it doesn't support, but is it accurate? I'm about to buy an external DAC and found this tricky answer

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?

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

It won't damage it it's a speaker it's not that sensitive.

Not trying to be rude or anything, but can you please ad an "@" symbol before my name in the OP, like this: "@nima0003" thanks!

Wow! Sounds great. Good work m8!

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)

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="HPHR Volume" value="25" />
<ctl name="RX0 Digital Volume" value="94" />

Anyone know how to make this happen?
Thanks

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.

UPDATE: I made it work! I'll add a reply below.
This might be a bit of a stretch, but I don't suppose anyone has managed to get bluetooth hearing aids (that support the ASHA protocol) working properly on this phone, either with OxygenOS or an aftermarket mod? I'm at my wits' end trying to work out why my mum's aren't working for calls while media audio is completely fine.
Stuff we've tried:
I've tested her hearing aids on my own OnePlus 7 Pro and they work absolutely perfectly. Media audio is fine, call audio is fine.
I tried looking at her phone's logcat output, from vanilla OxygenOS, and there were a *lot* of exceptions being thrown from the BluetoothAdapter constructor, from all sorts of apps. It seems that the static getDefaultAdapter() method was constructing a BluetoothAdapter incorrectly, which implied it was an OxygenOS bug.
And so we've just installed the LineageOS build from here, which I was certain would work - no joy. The issue is exactly the same; when the hearing aids are selected as the output device, no sound comes out of them, and the phone's microphone is disabled. With my own phone, it (correctly) uses the phone's microphone as the audio input.
Since media audio is fine, I presume it's not a hardware problem with the bluetooth adapter in the phone? But since the hearing aids work fine with my phone, running vanilla OxygenOS, it can't be an issue with the hearing aids, and since LineageOS fails in exactly the same way as OxygenOS, it surely can't be an issue with the operating system. I'm really out of ideas.

I managed to make it work!
Apparently OnePlus in their infinite wisdom didn't bother to put the hearing-aid and hearing-aid-mic audio route paths in /vendor/etc/mixer_paths_lagoonqrd.xml (that file name might be LineageOS specific - my own phone has two mixer_paths_*.xml files and neither of them are called that). I've attached a Magisk module with my fix in case it's useful for anyone else.
Please note: I've only tested this with LineageOS 18.1 and it's a modification of the LineageOS file I pulled from my mum's phone; I have absolutely no idea whether it'll work on OxygenOS.
Update: I've now tested on stock OxygenOS 11.0.16 (EU flavour) and it needed an extra line added, which I've now added and I've replaced the download here. Now it works perfectly on both OxygenOS and LineageOS!
I have absolutely no idea what I'm doing and this is provided "as-is" and nothing is my fault etc.

Hi,
I have the same problem with my nord 2 and oxygen 11, so do you think that if I root my device, and install your magisk module it they will work?
Thanks

Almost certainly not, sorry! The files seem extremely device-specific - but by all means give it a go; if your device happens to use the same mixer_paths file I'd expect it would work, and it certainly won't do any harm, apart from needing to wipe your device in the process of rooting it.
I'd be happy to try and make a module for you though if you can work out which mixer_paths file your device is loading and give me a copy of it. I should probably have written down my method in more detail for people with other devices...
I'll check exact commands and update this post with them later on, but essentially, if you restart your device and immediately dump adb logcat output to a file, you should be able to ctrl+F for the string "mixer_paths" and you'll find the phone loading audio routes from one specific mixer_paths_something.xml file during startup. If you then pull that file to your computer with adb (it's located in /vendor/etc, I can't remember if that logcat line has the full path or not) and post it here or DM it to me, I'll make the modifications for you. (And I'll actually document my method this time for future people.)
Also, if you need help with any of the above then please ask! I'm trying not to make assumptions about your level of expertise.

Hi, thanks for your support,
first of all... my symptom are: the bluetooth connect to my hearing aid through the Hearing aid helper in the settings but there don't show nothing connected, but from this point ahead, I can't hear nothing from the phone and no one can hear me through the mic in a call, for this reason I thought it's the same bug, what do you think?
The problem is that I don't have the phone rooted yet, also it's coming the first open beta OS12 for the nord 2, even if it's for the indian version, if it will work I would get a try, but if it is not , I'm will stuck with that beta until it will output the Final OS12.
Anyway I have got from my non rooted phone the LogCat.

It definitely does sound like the same issue!
Cynically, I think it's very unlikely OnePlus will get it working with the OxygenOS 12 beta - they don't care about anything besides whatever current flagship is. Honestly, given my experiences with my own OP7Pro I wouldn't dare to install a OnePlus beta; even their actual releases are barely fit to be called betas.
Your logcat output doesn't seem to have the line specifying the mixer_paths file. You need to restart your phone with it already connected to your PC, since the line appears right at the start while it's booting up, and I think it gets flooded out of the logcat log very soon after the phone has booted up. You definitely don't need a rooted phone to get this info - my own phone's not rooted.
Here's what I did:
Connect phone to PC, get ADB connected and make sure that the phone is set to always allow USB debugging from this PC.
Restart phone.
As soon as the computer registered the phone as disconnected (I was going by the "USB device disconnected" sound but if you're deaf or hard of hearing I think it's when the screen has gone black), I started logcat piped through grep. (I'll explain that last bit in a sec)
ADB should wait for a device to connect.
Around when the OnePlus bootup animation starts, the phone should connect to the computer and almost immediately you should get a line from logcat.
If you're using Windows, this Powershell command will filter logcat output and it'll just output the line you need:
Code:
adb logcat | Select-String 'mixer_paths'
If you're using Linux (or MacOS, probably), you can use grep instead of Select-String:
Code:
adb logcat | grep 'mixer_paths'
The output line you're looking for should look like this (generated from my OP7Pro):
Code:
04-27 14:36:30.932 907 969 D msm8974_platform: platform_init: Loading mixer file: /vendor/etc/mixer_paths_tavil.xml
So in my case, you can see the file I'm looking for is /vendor/etc/mixer_paths_tavil.xml and I can pull it from the device using ADB:
Code:
adb pull /vendor/etc/mixer_paths_tavil.xml
The mixer file your device loads will almost certainly be called something different, but obviously just replace the "tavil" bit with whatever your one is called. If you post that XML file, I'll try and fix it and put the fixed version into a Magisk module for you.
Note: If your file is called mixer_paths_lagoonqrd.xml then that's the same as the Nord CE so the Magisk module I already posted should work for you.

Bad news,
There isn' that file, and of course isn't called from the boot process.
I have got the all the boot log, but i don't know if there are sensible data inside, and anyway even if there aren't I would send to you directly.
I'm contacting you in private.

hi Qualx ,
you can help me for the the Hearing aid , i have onePlus5T android 10 OxygenOS 10.0.1 , root with twrp and magisk.
Thanks a lot ( sorry for my bad english )

Hi Qualx,
thanks for adding instructions on how to extract the mixer_paths file. I've attached mine from my OnePlus 6 running crDroid Android 12. I tried copy-pasting the 3 hearing-aid entries to the file, re-zipping the magisk module with my modified .xml and installing the module, but had no difference in functionality. Could you take a look at the original file and work your magic?
Many thanks!

Hello, recently after 5 years of using the hearing aid, took a new one for testing, with bluetooth function. Oticon hearing aid. It suits me very well, but there is a small but, Audio Sharing does not work on my phone Xiaomi Redmi 8 Note Pro. My android version 10.0 and bluetooth version 5.0, all as required. I have read the forum and found out that changing the operating system on the phone can help, but I don't know what exactly needs to be done. I plan to try putting ArrowOS and see if ASHA will be supported.

Hi, most success I have noticed are
ported OOS 11 ROM if available for your device
if not available you need to try with Android 12/13 custom ROM(s). [i prefer A13]
Please note its just not ROM which need ASHA feature enabled but also config needs to be set in source Device tree (Device specific configs to enable BLE options).
Also most imp hearing aid option dont appear under Accessibility until and unless you enabled the Bluetooth meaning if BT is turned off then option will disappear automatically and you dont find it anywhere.. turn-on then it will come under Accessibility.
Please go thru this link, recently I helped few to get the Audio streaming fixed.

hi @Qualx ,
i send message but no answer.

Hi, I have a OnePlus 6 and tried to modify the mixer file, but it doesn't work.
There is no sound when calling.
How do you know what to put in the path entries?
Edit: The file (mixer_paths_tavil.xml) won't attach. So here is the first part of the file. I hope that is enough to get the necessary info
Spoiler: mixer_paths_tavil.xml

Seems I'm in the same boat. Running LineageOS 19.1 on my OP6. It seems to connect fine but no streaming, even when the BT hearing aids are selected/active as output. Sound is sent to the phone speaker instead of the hearing aid.

Finally managed to get it to work. Seems A12 just doesn't like OP6 when it comes to ASHA.
I just flashed LineageOS 20 (A13) and I can now stream audio to my hearing aids (Oticon More 2).

But can you make and receive calls?
I updated to LOS20 today, and music streaming works.
Calls are still mute (as is the phone's ear piece, only sound during calls is from speaker).

No luck with that yet unfortunately.

It shouldn't be that hard, now that media is played.
Since the input has to be from phone anyway, the mixer just needs to route phone output to the hearing aids -- which, in fact, the dialer pretends to do: I can select the hearing aids, but no audio (and everything gets rather sluggish until I switch back to speaker,which hints at high CPU usage, supported by logcat's innumerable lines of
Code:
E audio_hw_primary: start_input_stream: cannot set hw params: Invalid argument
).
I got the nagging feeling, @AmarnathNR is attempting exactly that.

Hi there, I have a Xiaomi note 11pro 5g (veux) Do you folks here think that I can try a similar approach to get my heating aids streaming Audio with the phone ..the phone streaming audio to my hearing aids like you successfully did?

I got asha protocol hearing aids somehow connected to my xiaomi note 11 pro 5g (veux) with a pixel experience extendet and also with the evolution X rom for veux.
Everything works but only calls are not possible with streaming support.
I find it strange that whatsapp calls via asha connected hearing aids are no problem with both roms, ringtones play, media play everything is nice but no phone calls ??
Any Ideas ?
