My Microphone doesn't work on speakerphone?

I modified the mixer paths file to make my speakerphone louder but now my caller can barely hear me talk. How do I fix this?

Could someone help me? Maybe if I replace mixer paths file with stock unmodified file it will fix this? But then my speaker volume will be low....

Could be a serious problem. Check if these solutions work. Otherwise contact oneplus for rma

I have the same low mic volume when in speakerphone mode, i tryed the mic mod here:
http://forum.xda-developers.com/oneplus-one/development/mod-oneplus-one-stereo-mod-t2967925
And now the speakerphone mod is loud and clear but loosed a little the volume in normal calls mode.

I'll try to make another mod to resolve this issue. Keep an eye in development here:

My upper microphone doesn't work properly. When I use the telephone with the handsfree function, the other part doesn't hear me.
I have to talk with my lips touching the hole where this microphone is. If I speak only to five centimeters far away this microphone, they don't hear anything at all.
I have tried with several roms, so it has to be a hardware issue.
I would like to know if I can set up any parameter to use the normal microphone even with the hands free function.
I have improved it modifing the file mixer_paths.xml as shown below, but it is not enough
<!-- Analog input devices -->
<path name="hph-mic">
<ctl name="DEC5 MUX" value="ADC2" />
<ctl name="IIR1 INP1 MUX" value="DEC5" />
<ctl name="DEC5 Volume" value="40" />

</path>
<path name="anc-mic">
<ctl name="DEC2 MUX" value="ADC5" />
<ctl name="DEC2 Volume" value="100" />

I'm going to try some of your mods.

Yes, it worked.
I have modified a little bit the sensibility but it has fixed my issue.
I'm still without understan well how works each microphone, but at least I can use my opo as handsfree too.

Earpiece/Loudspeaker Volume Increase?

I would like to increase earpiece sound and loudspeaker sound, which lines must I edit in the mixer paths file?
Thanks.

I did indeed run a sound mod. However, the loudspeaker and in-call sound is still low. Do you happen to know which lines I can manually increase in the mixer paths? Thanks.

It's necessary root?
Enviado desde mi D6603 mediante Tapatalk

Root is necessary with 99% mods available on xda

I believe this is what I used on the Z1 to make the earpiece louder on the mixer_path.xml. it should be the same setting. Don't make it to loud though . I found that if it's too loud it seems to create an echo for the for the other person. That's with the Z1 anyway . Plus you don't want to blow out the speaker either.

Thanks, will give this a try. Having previously having the Xperia Z Ultra, it was far easier!
In the Z3, there are many more lines of code to go through...

^ @ raginginferno, I changed many settings yet no difference. Strange since my previous Z Ultra made a difference.
Many settings including headphones, earpiece, voice calls and digital volume was increased to 91/92. Saved and rebooted but sound is the same.

Microphone sounds very strange - wrong mic being used?

Hi there,
Whenever I record a message on WhatsApp (e.g. audio message to record a song) or when I simply record a video (doesn't matter where), the sound is very... strange. It's just not clear and the volume changes every time etc. I was thinking that the phone is using the wrong microphone to record the audio (the phone has two mics). Looks to me as if it's using the noise cancellation mic instead of the normal one.
Does anyone face this problem as well and does anyone have any idea on how to change this (possibly how to disable the noise cancellation mic)?
Thanks for reading

Hi, Are you using the stock rom ?

Sorry forgot to mention, yes I am using the stock rom. Didn't do any modifications or whatsoever.

Hi and sorry for the late reply, i'm having the same problem with viber, it can access only one mic whatever the position of the phone, i think it's a system bugs, and alcatel must correct them with more OTA updates.
If you think the problem is not a system bug and it's happening only to you you can use the mobile upgrade software from alcatel and flash you phone with the last firmware, because sometimes OTA updates can do weird things to you phone.

It is a software problem. I did a little playing around with the "mixer_paths.xml" and it got better. Unfortunately, I have not yet found the right values.

I suppose root is required for that? If yes, I'll root and try what you did. Every improvement is better than the current state..
Could you tell what did you change exactly?

I'm interested in buying the Idol 3 4.7" but have been put off by the poor audio recording quality; I tried it for myself in a shop and video clips had weird-sounding audio. To me it sounded as if noise cancellation has been enabled, meaning that it attempts to eliminate all background sounds in preference to loud speech (normally a person's voice would be very close to one of the microphones when making or receiving a phone call), but in other circumstances it would get confused because any voices (if present) would often not be much louder than other sounds.
Some phones have an option to disable noise cancelling (perhaps under "Call settings"?), though of course you would have to re-enable this feature if you wish to make/receive calls in noisy environments. I had a quick look in the Idol 3's settings (stock ROM obviously) and couldn't find anything that obviously related to noise cancellation. Reducing microphone levels might help as previously suggested since it's then less likely to detect 'background' sounds (and compensate accordingly) but that still won't eliminate the effect altogether.
If not in the settings, perhaps there's some other method of disabling noise cancellation? Would a custom ROM have this feature?

I'm also having sound quality issues, with awesome player there is audio microcuts and recording quality is a mess. However, with nu player microcuts are solved but not poor audio quality when recording. Even though i updated from 010 06 to 010 07 it persists, performing a clean upgrade (not through OTA).
People are reporting the same in reddit https://m.reddit.com/r/idol3/comments/3im55s/is_alcatel_going_to_fix_the_idol_3s_horrible/

Any new info on this? Was thinking of buying this phone. Did anyone test with CM?

microphone got only problems with recording when the subject is too far away. no problems during the call. i think this is hardware problem because we got much updates and no result
and is only one defect from this phone.

I find all of these statements kinda odd because I haven't had any issues with stock rom at all with recording, but on custom roms I had issues with apps other then actual camera apps, facebook messenger being an example, it sounded like it was under water. I assumed it was using the mics wrong, but going back to stock I haven't had any problems at all again.
Did anyone try turning off the JBL audio effects out of curiosity? Im not sure if that could actually effect the mics but you never know.

In 010 08 firmware version, still facing this problem while recording audio. Tried to disable JBL audio without success.

Any new info about fixing this issue ?

If I use built in microphones it sounds dreadful. However, using jbl earphones the sound recorded is very good (clear and with no cuts).
So, my point is that is a hardware problem or maybe noise cancelling or a mix of both. At least i figured how to "solve" the problem but is unpleasant wearing all the time the earphones.

Galaxy S7 (and S7 Edge) easy headphone volume hack *root* Tested on SM-G935F Exonys

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!!

Is there a difference between this and Sound MOD by ZuBi182?

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

But if you figure out how to do so these changes will "theorically" swap the call mic to the voice recording mic.

on oreo and pie, editing file in /vendor/etc will result the value to revert back to its default.. so, i stay on nougat for the time being and not use any tasker or create my own magisk module.. i found the line to swap bottom mic to use top mic but it causes other caller to hear themselves while calling..
so, in short;
1. microphone works but it only use rear mic (if you use voice recording app with multiple sources for recording, select main mic as source, it will use rear mic because its already swapped as main mic)
2. whatsapp voice message and audio recording works but you may have to talk to rear mic or talk louder
3. call works but other caller may heard themselves..
here are the line in mixer_path.xml in /system/etc/
find these codes and change dmic1 to dmic3 and DEC7 to DEC6
Code:
<!-- TX Main-mic D:4 dB -->
<path name="handset-mic">
<path name="dmic1" />
<ctl name="DEC7 Volume" value="88" />
</path>
<!-- VR MIC 1st D:22 dB -->
<path name="voice-rec-mic">

</path>
<!-- Unprocessed MIC 1st D:2 dB -->
<path name="unprocessed-mic">
<path name="dmic1" />
<ctl name="DEC7 Volume" value="86" />
</path>
and find this line in build.prop, change it from fluence or fluence pro to none;
Code:
ro.qc.sdk.audio.fluencetype=none

Great you could solve it!!, It will be helpful for lot of people.
Did you try to apply some air pressure with compressed air inside the mic "hole / notch" near the charging port? Some users reported it works, because the mic's diaphragm gets stuck and doing this will release it.

Did that but no luck.. my first pixel got same problem.. then i returned it and get another one, it also has same problem.. luckily, experimenting with mixer_path succeeded..
