In-call volume and MTK Engineering mode - General Questions and Answers

Is there documentation somewhere about the various settings of Engineering mode of MediaTek-based phones? Lots or articles offer a basic description of it and the codes to enter it, but I haven't found a comprehensive guide about particular settings.
Specifically, I am interested in changing in-call volume. In the Hardware testing->Audio->Voice section, I can change values for NB, WB, and SWB + Receiver, Receiver_SV, HAC, Headset, etc. What do all these refer to, specifically?
One post on XDA advised to change the NB, WB, and SWB values of the Receiver setting, but the result affected the mic volume, which was not what I intended.

This would be great. I've been messing around with it but I think I might have broken in-call volume from MIC with BT headset...
I wish someone could explain it in detail.

Sorry for the late response.Im in the same boat Im no expert .The best I could gather is to Max out all of the fields NB,WB,SWB with the highest numerical values allowed(I entered audio>vol>voice252,240with index of 160)(for audio playback I used no less than 180 for index gain) and for speech enhancement I referred to this other post by "walopower"
https://forum.xda-developers.com/t/...-enhancement-parameters.3082461/post-71643868
basically dropping down to index 3 for calls and raising that to 255 all levels!
Lastly I edited the build.prop (optional)
ro.config.vc_call_vol_steps=30
ro.config.media_vol_steps=30
My gains are not super loud like I would rather it be, only about 3 times as good as stock
Its all very time consuming but it works!
If anyone figures out a way to get the in-call super loud I would appreciate it!

Registry help needed please- SPEAKER VOLUME

I have used the tweaks found in the Wiz/Wiz section (and subscribed to a thread without much response http://forum.xda-developers.com/showthread.php?t=256734 ), as well as other WM6 device tweaks and ones found by googling...my issue is, and no one seems to know what/how...
My internal speaker, the mono speaker used for phone calls, is very low. The tweaks I applied have made the speakerphone louder, and my BT earpiece louder, but if I am in my house, and get a call, I usually dont use BT or speakerphone. I sound like a reverse Verizon commercial...instead of "can you hear me" it is "I can't hear you".
I have used the audiogain tweaks (also known as audiogain cc), and also HKCU\Control Panel tweaks. I have reset my device. My physical settings are cranked all the way up (slider, and volume icon).
Does ANYONE know what reg entry specifically targets the internal single (top of device between flashing lights) speaker to increase in-call volume??
I dont mind being a guinea pig, so if you have any ideas about this issue, I'd sure love to hear from you and try them out.
As always, thanks in advance!
***PS- am using AMPv2 rom with radio 2.37 IPL/SPL 2.26 (if this helps at all)
BUMP
Does anyone have any idea which reg entry may specifically target the single internal speaker? Please and Thank You.
wish I did. that would be the first thing I would fix. try apache forum as well. it is basicaly the same hardware, But I remember that a lot of verizon users traded their's in innitialy, because they could not hear anything.
hERE ARE MY RELATIVE REG SETTINGS FOR YOU TO COMPARE`
HKLM/Software/Audiogain
EAC_GAIN_EMBEDED (mine is set to: 6d)
HEADSET 67
EARPHNE_UPLINK VOL 19
HEADSET_UPLINK VOL 13
RECIEVE_UPLINK VOL 18
SPEAKER UPLINK VOL 10
HKCU/CONTROLPANEL/PHONE
VOL 0X0000FFFF(65535)
You may also want to look at these:
HKCU\ControlPanel\SoundCategories\InCall
HKCU\ControlPanel\Sounds\Loudest InCallVolume
InitVol 0x00000001(1)
HKCU\ControlPanel\Volume
Here are my settings:
Key 0x00010000(65536)
Mute 0x00000003(3)
Ringer 0xfffffff(-1)
Screen 0x00010000(65536
Volume 0xffffffff(-1)
I believe you will have better luck adjusting the volume in HKCU rather than HKLM.
I hope this helps you figure out this problem. I know many of us suffer. Somehow mine is either ok, or I'm just used to it.
Mahalo!!
Thanks for your response. I have played with many of those areas, but perhaps I haven't figured out the right tweaking level yet, so I will go back to those regs and play some more. I will check the Apache section out, perhaps I could gain more insight there. I'll say this...if I finally find the right settings, I should win a front row seat to see Barry Manilow in concert--make my hard work pay off (yes you read correctly, I love Barry!)
I will certainly post any findings. This is a real pain in the ass. I love my wizard, but the speaker issue is frustrating.
Thanks again for your insight.
**EDIT**
HKLM/Control Panel/Volume AND HKLM/Drivers/Speaker both potentially affect volume (I think), but in my rom, there is no settings. I am not sure if the no settings IS the default settings, and am not sure if I can futz with these?? Does anyone have an idea if it is safe to attempt tweaks in these 2 areas??
it is safe if you back up your reg (original)
these settings are in my 588 (which I haven't posted yet) which I will post when it is ready. it is currently being simmered like a stew.
PS. when I was tweaking the camera graphics, I noticed a lot of functions that are not in the registry. about 1/3 of the icons do not show up under any circunstance. which leads me to believe that the program is capable of more than the inhibited registry.
so perhaps I will export my reg for you to try. unfortuantely, I can't post them using opera mini
How about this one,
HKCURRENTUSER\ControlPanel\SoundCategories\InCall \Attenuat ionCategory = 0
The setting was on "2", changed it to "0"

What did you find when making that change? everything I have read claims it only affects the incall beeps when raising the volume slider, so I haven't really bothered with it...but I have been toying with the possibility, just for sh*ts and giggles, because at this point I have pretty much exhausted the reg entries I can think of.
Thank you for your response. Every little bit helps, and keeps me from just randomly choosing a number out of my ass to change the reg entry to!
Did you try it? It should work. It will "increase in-call volume??" You will not crash your device for trying it.
I noticed only a slight volume increase using the attenuation fix. My speakerphone sounds great though. I may just have to save my pennies and get the speaker replaced==maybe it just gave up the ghost, because none of these reg entries is giving me the volume I need.
Any other suggestions, tips, insight, etc would be appreciated.
BUMP
Still seeking some insight. Apparently the repair shop locally wants to charge LOTS of money for the speaker. The speaker worked fine prior to installing the AMP rom. I like the features of the rom so don't want to swap if I don't have to, but I REALLY do need to fix this speaker volume issue.
Can anyone provide me further assistance/suggestions?
Thank you in advance.
while your at it does anyone know what reg entries are for upping the mic evel to make it more sensitive?
I know mine increased when I tweaked something in the 4 audiogain files...but I don't remember which ones I tweaked. Look through the thread I linked in my first posting it should help.
This is my solution , and on all versions and over 30 devices tested by me.

AudioPara_.csv file -- columns of adjustments

Does anyone know what the different parameters in the columns adjust in the AudioPara_.csv file? Seems like this file, if tweaked properly can fix several sound issues. Some seem fairly obvious but others not.
There also seems to be some kind of compression/limiting going on, loud noises in the receiver will bring volume too far down and then I can barely hear the other person. HTC is probably protecting the tiny speakers, but it seems it's not adjusted properly. Sometimes even first outgoing ring is nice and loud, but the next is soft. Go figure!
This is also true for the outgoing mic. I have had some people say it's too loud from my phone. Sometimes I can even hear my own background noise loud through my earpiece, similar to the mic sensitivity thread. If I talk fairly loud then sometimes the overall volume drops, including my receiver, regardless of the microphone AGC setting.
With recording there seems to be some control from the AGC enable switch setting, but even when it's turned off, there is some sort of limiting. I've tried a few different audio programs to record and they respond similar. The gain controls offered in these programs don't seem to do much. Recording music easily clips the sound! The AudioPara file has controls for CE_REC_INC_MIC and CE_REC_EXT_MIC, which seem like this might control some of this. Again there are many columns of adjustments.
Seems like this file can fix a lot, but it would be beneficial to have a better understanding before blindly trying this and that as many have. Does anyone know where to get replacement speakers if we blow one from the wrong settings? Please share any knowledge you have about these settings and suggestions of where to find out more. It seems like more than just gain and volume that needs adjustment.
Thanks!

[Q] Star 9220 engineer mode - audio setting help needed

I'm trying to improve the call quality, specifically what I hear through the main speaker, to make this phone useable. Currently its very tinny.
I found on a russian forum the dialpad code to engineers mode *#*#3646633#*#*. That brings me to a menu:
Battery Log
Touchscreen
GPRS
Audio
Camera
WiFi
Bluetooth
NetworkInfo
Autoanswer
YGPS
AGPS
EPO
VideoTelephony
Display
Memory
IO
Power
Baseband
FM Receiver
SIMMeLock
SystemLog
De-Sense
Matv
CPU Freq Test
BandMode
Can anyone provide an explanation or instructions for these?
I'm most interested in the "Audio" menu. If I select this I get:
K Tone
Normal Mode
Headset Mode
Loudspeaker Mode
Speech Enhancement
Debug Info
Speech Logger
From there I get drop down menus with FIR 0, FIR 1, FIR 2 etc, Ring, Key, Mic, FMR, Sph etc, Levels 0 up.. and two input boxes, one for value (0-255 and another, Max Vol. 0-60.
Any explanations, instructions or help would be gratefully appreciated.
Have searched this forum and google and the closest I can find is this but I can't make much of it, even with translate.

I'm really excited that this might give some useful control to address a problem. I'm suprised that with all the experts out there no-one has responded yet. I'm sure the answer to this problem will help others with tinny phones too. Anyone....?
Did I put this in the wrong place? Not one answer :-(
wish i could help you, im looking for the same answer, except for music, it sounds tinny as heck, not originally but has developed a tinny sound that i feel could be fixed

[Q] Increasing volume

Looking for a good way to increase volume slightly, specifically for the speaker or the bluetooth. I've found tons of great articles that talk about editing mixer_paths.xml. Those instructions work great on nearly every other android phone I've seen...but not the M8. The naming is completely different.
For example:
- Articles say to change the speaker, you need to go to the <path name="speaker"> section and change the volume.
- On the M8, that section is empty.
My guess is that it's different section names than other phones, but I haven't figured out which is which. Anyone know?
If you're rooted you can use V4a audio mod. It has a lot of settings including increasing the gain. Mine is so loud at full volume I actually have to talk over the sound coming from external speakers!

I'd prefer not to use V4a. Tried it, didn't care for it. I'd much rather find out the really easy text change in the mixer_paths.xml
Thanks though!
*Bump*
Currently just using H/K for the volume boost it gives bluetooth. Would love to find out what setting to change to adjust this myself...

Protect headphones by configuring a high pass filter in mixer_paths.xml?

Hi,
I have a rooted Xperia Z5 and I have 32 ohm earbuds that have a very clear bass reproduction, and they sound great with the phone's built-in impedance matching feature (called "Automatic optimisation" in the settings). However, that feature also "enhances" the low end to the point where the earbuds physically break. I don't use any EQ or bass boost, because it's already more than enough.
Now I've seen a lot of sound mods that purportedly boost bass and whatnot, and wanting to do the exact opposite of that I decided to try looking for a tutorial on what all the different settings do and how to change them, which I couldn't find. I tried looking at my own mixer_paths.xml to see if I could make sense of it by myself but although mostly friendly named the settings are pretty cryptic and I'm not sure if I could for instance, if I found something that looks like a high pass filter in the telephony mixer channel, simply copy it to the headphone channel and have it sound right or even work at all.
To clarify, what I want to do is just cut off everything below, say, 30Hz, and then see how high I can go before things start to sound bad, or maybe do a more gentle roll-off if that's possible. I've tried the graphic equaliser but the 5 bars available are way too crude to do something like this. Doing a -1 or -2 on the bass boost slider certainly helps but it affects too much (the range is too high).
So any help on whether or not this is even possible and if so where I should look are appreciated. Thanks!
