[Q] Call volume too loud through wired headset

When taking calls through my headset, the voice on the other end is too loud, even when the volume is set to 1/5. I've tried different headsets to no avail. Does anyone know how I can reduce the volume of the call below the minimum volume setting? The phone is rooted.

you could try changing the entry in the mixer_paths.xml file located in the the 'etc' directory.. you'll need root.
look for..
<path name="voice-headphones">
<path name="headphones" />
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
<ctl name="RX1 Digital Volume" value="84" />
<ctl name="RX2 Digital Volume" value="84" />
</path>
and change the 20 values to 15 and the 84 ones to 83, this should give them the same values as music through headphones.. reboot to take effect, if there no difference change them back

Thank you!

[MOD]{Stereo+deaf mode+mic rec fix} [Volume Mod] Ben Volume v.1

Its simple. A lot of sound mods out there but none of them suited my needs. Each of them had different mods that the other didnt have so i copiled a mixed_paths.xml with @olokos sound mod v 2.5 adding @odl 's mic fix and @dontbelive stereo speaker mod v 2 and made a Monster Stereo Volume Mod. Ben Volume
Req:
Rooted 4.4.4 Stock Sony Xperia Z1/Z1C/Z1S/Zu
Instalation:
Just download, rename the file to mixer_paths.xml and copy the file to system/etc and set the correct permisions.
WARNING:
THIS MOD CAN SERIOUSLY DAMAGE YOUR EARPIECE. DO IT AT YOUR OWN RISK ITS BETTER TO LOWER THE VOLUME A BIT WHEN LISTENING TO THE SPEAKER
DOWNLOAD
PRESS THX IF YOU LIKE IT.

I suggest 87 for volume on both channels. This value is sufficient for louder volume without risk of damage.
The problem with mic occurs when we set more bass for speakers:
Like this: <ctl name="SLIM_0_RX Format" value="S24_LE" />
I'm using S16_LE now, less bass but no problems with mic. @dontbelive is working to get more Bass without trouble for mic recording.
Cheers

mixer paths

The mixer paths is like none Ive seen before. Im headphones there are no RX volume adjustments any where, has anyone cracked this yet? The volume is way to low
Thanks

hey USMC. can you clarify what you mean by "None i've seen before"? what device's mixer paths are you comparing it to?
this is an area of interest for me as i have tinkered with mixer paths but i do not know the results yet because i haven't been able to get my rom working. the RX volumes are in there. look again. not just mixer paths, but the other mixer path files there's 7 of them

I have the HTC u11 and the structure is unusual compared to say the pixel phones. If you were to put the 2 XML side by side you would see what I'm talking about. For the HTC there no RX paths in which to change the volume where on other phones those volume values exist

HPHL & HPHL from what you said before is already maxed out at 20 but where is the digital volume values on the U11? Viper's ROM has an audio boost for headphones, but they have edited almost every mixer path file. I'll compare when I have the time.
The OP3T was also similar to this, HPHL and HPHR were already maxed out at 20. Editing digital volume via a kernel (Such as Flar's) introduced distortion immediately so wasn't worth it.
This is also quite nice to look at
https://docs.google.com/document/d/1NqfEpbhXfXyqRPJoLxtifbEMNCEuVOIokwT5kyjJ2KI/pub

Im sure it isnt structured in the same order, no surprises there but its similar in referencing which is all that matters.
There are 7 RX Digitals from RX1 through RX7 in the U11 mixer, I think RX1 and 2 has something directly to do with headphones, not sure what the other RX's do. Probably another two is responsible for the top and bottom speaker and who knows what the other 3 do..
There is also a dedicated RX for ANC, 44.1 headphones etc. Thats not in the main mixer path

Yeah most of the digital values are set at 84 on the U11 as well, not all. Anything more than 84 and you'll start to get distortion if you're volume rocker is set on the higher levels. The registered values are 0(-84 db) to 124(+40 db)

On Vipers ROM the values seem to be set to 88 for most things.
Using V4A increasing software gain by 6dB doesn't introduce any audible background noise or distortion on my RHA MA 750. Also noticed that in "mixer_paths_tavil" they have removed some lines.

I'd be content with using the Usonic headphones if they weren't so crackly at the high end, sibilant songs sound harsher than they should.
On another note, HTC have done something to the mixer paths that has now ruined editing volume steps. On the original firmware, I could set volume steps via Magisk modules to anything I wanted, and it worked fine for the 3.5mm adapter. After updating to 1.13, the volume steps simply repeat once you go past step 15, which is rather annoying. (It is also busted in Vipers ROM).

I forgot about RX0, there's 8 RX's.. anyhow
Actually the before and after is reversed. HTC added in the Comp switches to the path names. if my memory is right and assuming things haven't changed since then the volume step controls are handled in the framework.jar, I've applied code on the increase volume step mod before on previous devices.
Besides HTC didnt really alter the mixer path too much from update to update to warrant breaking the volume step so I don't think mixer path has anything to do with it at all. the few tweaks HTC made is related to headphone output.
Also for Usonic try editing the ANC(active noise cancellation) values then maybe reduce the RX and increase the HPH

Right I've done some actual testing

unless maybe try turning off the ANC OUT enable switch to 0?
anyway. so there is no difference editing the headphones path and headphones 44.1 path? also try editing the initial HPH settings back to 20 too. they originally had it at 20 but changed it to 16 on the latest version.
that's what i have set on my Sprint DK11 rom. 20 for all HPH. 84 on ANC, HP and HP 44.1 paths. glad to know there is an audible change with ANC

We have lift off in terms of editing audio levels with the USonic Without ANC enabled
I accidentally deleted a comma over the value hence it didn't register when I tried it.
Code:
<path name="headphones">
<ctl name="SLIM RX2 MUX" value="AIF4_PB" />
<ctl name="SLIM RX3 MUX" value="AIF4_PB" />

[B]<ctl name="RX1 Mix Digital Volume" value="74" />
<ctl name="RX2 Mix Digital Volume" value="74" />[/B]
</path>
I set both to 90 and I hear no distortion, of course I didn't max out and in fact will lower it. The USonic is super loud now. Either way, all other mixer path edits seem to be ignored. The USonic headphones don't change at all until you edit the mixer_paths_tavil.
Next step, trying to do the same with 3.5mm adapter, so far all my efforts have failed. 3.5mm adapter doesn't get louder or quieter regardless of what is done.

So the ANC path works for the Usonic with ANC on and the headphone path is also for Usonic but with ANC off?
Headphone 44.1 is a no go? Just to clarify and confirm. Thanks for testing! Yeah 90 must be a little too loud, 84 is more neutral but louder than 74 that's for sure.

Yeah ANC path for ANC on and headphones path for ANC off.
44.1 doesn't seem to change anything at all

and the headphones path doesn't do anything for the 3.5 mm headphones as well when listening to USonic and regular headphones side-by-side?
hmmm i wonder what else would change it without altering values all over the place.

Yeah editing the headphones path doesn't seem to touch the 3.5mm headphones at all. Lowering the value to 10, the USonic without ANC enabled is barely audible. Plug in the adapter and the 3.5mm headphones volume is untouched.
I have no idea where the values for the adaptor or external audio devices would be. There is a ton of USB_AUDIO references in the files but they all seem to have a value of 0 or 1.
I can't really find how it is implemented on other devices either.

Time to put on my thinking cap lol
I thought i2s would of had something to do with it..

more than 84

I forgot about RX0, there's 8 RX's.. anyhow
Actually the before and after is reversed. HTC added in the Comp switches to the path names. if my memory is right and assuming things haven't changed since then the volume step controls are handled in the framework.jar, I've applied code on the increase volume step mod before on previous devices.
Besides HTC didnt really alter the mixer path too much from update to update to warrant breaking the volume step so I don't think mixer path has anything to do with it at all. the few tweaks HTC made is related to headphone output.
Also for Usonic try editing the ANC(active noise cancellation) values then maybe reduce the RX and increase the HPH

On the Nexus 6 I took values from 84 to 100 with no problems with distortion or clipping, and as far as the other mixer paths go, most of those arent adjustable. I will keep tinkering and let you know if I find a combo that raises headphones to an acceptable level
I think I have it narrowed down now enough to say that once I find out which MP addjustments are the "master controls" of the entire XML we will be good to go

You can edit the mixer path tavil which will boost ANC/USonic headphones but believe me when I say the USonic does not need to go past 84 unless you are trying to damage your hearing or the headphone drivers themselves.
As for editing loudness from the 3.5mm adaptor. That is routed to USB_AUDIO which has no editable settings unless you re-route the sound to a SLIMBUS mixer path. By all means give it a go though.

Any suggestions/ development in terms of making the ear-piece & speaker louder by modifying the mixer_paths?

[MOD] Stereo sound mod

Stereo mod for xiaomi mi4c (libra)
Based on [OFFICIAL] sources Lineage OS.
Includes:
1. Connecting stereo sound "Speaker - Main Speaker" [LEFT-RIGHT] respectively.
2. Increase the volume of device. (I recommend to use it in conjunction with viper fx with "speaker otimization" enabled.)
3. Increase the sensitivity of microphones.
DISCLAIMER:
I just report to work on [official]lineageOS I am not responsible in any way for anything that happens to your device. You do so at your own risk.
However, it works for most users without problems.
Installation:
You can install a couple different ways including extracting the files included in the zip and manually pushing them to system/etc, set permissions to rw r r, and reboot or just flash the included zips in your custom recovery.
CREDITS:
Cozzmy13 - He made LineageOS port and achieved official support. I used these source files.
kevinkvothe - Thanks for the first port of the stereo mod on our device. So I use some of the developments from his mod.

STEREO MOD
REVERT TO STOCK
With love from Belarus

Anyone tried this? I'm still on MIUI 9. Will try it when I get back to LineageOS.

Yeah man, it works as advertised, thanks. Would you be able to tell me (by line # or title) which values I need to change (I'm guessing the ones which are 93 now) for headphones and earpiece? I may want to increase them.

can you make this stereo sound mod for meizu pro 7 (flyme 7)?i will be glad if you can

Sadly this method doesn't work on Android Oreo and Pie Can someone make one for Pie? It'd be really great!

How to make call audio work with custom rom

Using squid2's XML files from his github I was able to get phone calls working on all of the ROMs I used, I'm also using Google dialer instead of factory.
Replace the current ones in the system/etc folder and reboot and calls should work.
https://drive.google.com/file/d/0Bzk7IAINn5jfbmFDUG5HaEFTLUE/view?usp=drivesdk

The only problem I'm having is call audio is kind of low and I'm not sure exactly how to make it louder.

In stock ROM, there is: /etc/mixer_paths.xml
I imagine it is in the custom ROMs as well. If so, copy & open the file in Notepad++, then edit line 737 (or look for <ctl name="RX1 Digital Volume" value="84" />
84 is the stock level. Increase it to what you'd like, but don't go crazy. I made mine 88. Save the file and replace it on your phone. Set permissions to rw-r-r and reboot.
You can also edit overall speaker volume by editing lines 25-31, 35,36
<ctl name="RX1 Digital Volume" value="84" />
<ctl name="RX2 Digital Volume" value="84" />
<ctl name="RX3 Digital Volume" value="84" />
<ctl name="IIR1 INP1 Volume" value="84" />
<ctl name="IIR1 INP2 Volume" value="84" />
<ctl name="IIR1 INP3 Volume" value="84" />
<ctl name="IIR1 INP4 Volume" value="84" />
<ctl name="DEC1 Volume" value="84" />
<ctl name="DEC2 Volume" value="84" />
Again, don't go crazy as you could blow your speaker or your ears.

The one I have used works well at the proper level of sound for the boost version. I legitimately believe that there are minor differences with parts in each Moto E4 variant. (I had this issue with the camera back then with the LG Volt {Virgin vs Boost})

CDMA?
Edit: wait, I'm in Qualcomm, pretty sure these are all CDMA right?

No. Only sprint (and all Sprint mvno's) and Verizon are CDMA.

You could probably limit your max volume that way. Seems risky and unnecessary though. Why not just turn the volume down?

the minimum volume is comfortable but some people while calling mentioned that they are hearing their own sound back as an echo (may be their sound is being picked up by my microphone )....so i was thinking that reducing it below minimum level could solve it.

Wrong section brother.

No, that's a network issue. Nothing to do with your device's volume in any way. It happens to my wife occasionally on her e4. Usually in certain locations. I know it's the network because it happens with her other phone as well. In her case, it's Sprint (or Sprint mvno).
