[Q] Xperia V: Low Bluetooth In-Call Volume

Hey together,
I own an Xperia V and want to use it in my car to be able to make calls without touching my phone.
In my car I have a Becker igo8 navigation system (active 43 control).
The problem is that even if I set the volume to max at the becker and the xperia, the in-call volume is really low.
Low means enough when the car is standing still, howewer no way to hear something at 30km/h or more.
I'm currently at Rizal's Rom (Lovins X Z2, A.2.5) and here are the things I've tried:
--> Practically any app on the appstore --> none boosted the volume
--> Viper --> Really nice, however regarding bluetooth it only boost the music volume not the incall volume
--> Modified the snd_soc_msm_2x_Fusion3-File. I've tried manually editing the parameters (RX Digital Volume) and also
used modified versions by other authors.
With a modified file I had it louder for one week. Then I wanted to write an android-app which changed the settings. By the time I was finished, the volume did reset itself to standard values (I don't know why), meaning that again it is pretty low.
I can't reproduce what I did to get it load again. I sat in my car for hours, trying to change parameters, save, reboot and test by making a call.
Next try: using the AlsaMixer-App from the market. While a call was active (mailbox) I changed __every__ setting which included "volume" in its name, I could find to the max that alsamixer told me. While I could change the speaker-volume this way, I wasn't really sucessful regarding bluetooth incall-volume.
One setting "Voice Rx Volume" I could change in between 0 and 5. When setting it to 5 it didn't change, however when I lowered the incall-volume with the slider and then increased it again, the volume was louder. Loader in this case however isn't nearly enough to make a call while driving. It also isn't nearly that load as it was before when playing around with the snd_soc-file.
One note: while I did all those tests, I was on Rizals old version of the rom. Now I am on the new version A.2.5). Don't know if that makes any difference.
This is why I am asking you for help. Any ideas? I would really love to be able to make calls, as it only is a matter of volume...
Cheers

One note:
Adding ro.config.vc_call_vol_steps=10 to build.prop also doesn't change anything.
I could find out via logcat that:
the "stream" responsible is "Voice RX Volume". Apparently 0 is the maximum, the higher the value the smaller the volume. Via alsamixer 5 is the lowest, by using the buttons on the phone in call, logcat displays level 100 at minimum. 0 is the maximum in both cases.
So, how to actually boost that Voice RX volume? I cannot find it in snd_soc_sms's fusion3-file.
Any ideas?

Hi Elarion,
Did you ever find a solution to your low call volume? I have the same problem on my Xperia T, volume on the Bluetooth headset is ridiculously low and I need to fix it!

Boost Output Volume on 6.0

If youre like me and you like listening to your music with good headphones and want to feel that bass rumble in your head, you might have noticed that with the update to 6.0 (In my case to B565) the output volume might have gone down considerably and that now the max volume isnt just enough to make you eargasm. So i researched a lot and found out that the max volume settings are set in some .xml files located in /etc and /system/etc but the thing is that with huawei phones we dont just have to edit a single .xml file to raise our max volume, we have to edit a whole crap ton of them depending on our region, vendor, model etc.... So instead of having to open all those files and edit just the correct string, i found out that AlsaMixer (Available on google play) works just fine with out devices!! I also found out that the max output on 6.0 is stuck at 80% dont know why.
So, to get your 20% of max volume up, all you have to do is open AlsaMixer (or all those other .xml files if you like doing things the hard way ) and edit the lines:
-HISSC_SMT_HSL_GAIN (this is left headphone gain)
-HISSC_SMT_HSR_GAIN (this is right headphone gain)
Their default value will be 12, just go ahead and set that value to 15 which is the max value and enjoy your new volume
NOTE: There are tons of other strings you can edit to increase output of speaker, earpiece, etc...etc... but since I didnt need to increase these I didnt take the time to find out their variables, but if youre interested on increasing the speaker volume just open the .xml files and go to speaker and find the gain variable and change it with Alsa.
Hope I made your day

Do you know how can i set plug in/out -> music player on/off or music play/pause??

You might be able to do that with Tasker or a similar app. ALSA is only in charge of the sound.

tested and working good. only thing i noticed is that after i modify the value it wont save for the next time i use the player so i have to edit and apply again.
really thanks for sharing

So looking into AlsaMixer, this is an app for a rooted device. Is there any alternative methods? I just got my phone finally back up and going again after an IMEI loss and am a little scared to do anything further in the system like that.
Also the fact that the description on AlsaMixer doesn't say anything about supporting MM... Has the had any issues for you?

I dont think there are any other *effective* methods out there that dont imply rooting your device or something of that behaviour sorry. And yes it does support it, at least for me even though it says nothing.

Not a worry... I'll just have to build the courage up to rootmy device :/ ah well. Thanks for responding so soon

and this works only for headphones? i also want to increase volume on speaker

I think you can, but have to find the proper string for speaker

Exactly, you have to find the string for the speaker. (Be careful though because you could cause damage to the speaker)

which is the line for speaker gain?

You solved what? We already know about dolby atmos, but this is different.

Yes Dolby Atmos gets a little better sound quality than stock. But it doesnt boost output volume in any way or form. For that the only thing that works is editing the ALSA setting but for the speaker I dont know which string you have to edit because as i said im not interested in listening music through my phone speaker, i was just interested in boosting the volume from the headphones which I thought were too low. Anyhow I discourage everyone who wants to boost their speaker higher than stock, as this phones speaker sounds pretty high, even too high sometimes and you could risk damaging the speaker or braking it.

is it even possible to boost without root? i guess not. but app can probably deliver higher sound.
for root users theres usually a xml file in system/etc i can't tell which one it is since i'm first time huawei user but if u got root why not use viper4android it boosts the volume like

I would like to boost the volume only for my headphones. Which xml files should I edit? I am thinking of using a file explorer to edit the values on OP for this.
Thanks in advance.

Use the playback music controls xposed module.Its awesome and you can also change tracks using volume buttons if you like. The autoplay option is in the settings.

I've found out how to boosz permanently, I guess... System/etc/audio/hissc/mixer_paths_ALICE.xml
Open it with a text editor, and change HISSC_SMT_HSL_GAIN + HISSC_SMT_HSR_GAIN from 12 to 15.

Hello, it's not so safely but it's working but you need to edit the sames files but the one with R too, few lines after (left/right).

Volume Boost Note 8

Is there a way to boost the volume without Root?
Thanks for any help!

need that too!

First make sure your media volume limiter is off, then go to equalizer and push all frequencies to max, that should give you about 10 dB extra.

Can't promise that it will work but they're is an app called SpeakerBoost that I've installed
..... Seems to work

how do you do that

settings/sounds and vibration/sound quality and effects
actually just go to settings, click on search functions (circle with with line on the bottom, top right corner) and type media volume limiter, or whatever function you're looking for

I try it, but continue with low volume. My previous Note 2 had louder audio.

ok

Just a comment, my 950F does not have a media volume limiter option

Download "Speaker Booster" on the Play Store. Hope this helps

I tried pretty much everything but nothing really actually worked. If you use the SoundAlive profiles or boost the EQ it just limits the two top volume levels from working.
I have now rooted and manually changed the mixer_gains.xml file and it's amazing now. super loud with no distortion at all.
Sadly rooting is really the only way to go. Dunno why Samsung limit the volume so much when the DAC is capable of a far better volume output. It's the one thing that really lets this handset down.

Can you link me the mixer paths you used?

All you need to do is change the values in mixer_gains.xml as per the screenshot. Root only of course.
This is only for the wired headphone volume.

After trying about 5 models of headphones and being ridiculously low volume in all of them (especially in Spotify and YouTube videos), I found a expensive solution, but that has solved the problem withoutroot, i have bought the Jaybird X3, very good quality, very good volume and good insulation, despite being in ear.
I still think that with normal headphones, such as those that come in the box of AKG, Xiaomi Piston 2, Sony STH32, Sony SBH24 or even the great AudioTechnica M40X the volume is ridiculously low on this mobile.
Greetings.

It is ridiculously low, and has been on Samsung mobiles for a while now. Seems they need to protect us from ourselves. sad.
As stated above, root and a simple change to a text file makes one hell of a difference.
Another good solution is an external DAC like the Creative E3. It works well too and no need to root.

Hey, I'm with you all ; the volume of the note 8 is low. Now I tried every GD volume app on the play store and none work. I kept looking and I found one that works: Music Equalizer and Bass Booster by Coocent. This app no **** will increase volume. I swear.

Could you please advice if this would work if you use Bluetooth devices, such as speakers or headphones? I mean it is so annoying that samsung actually achieve year over year to have worst volume... just when you think it couldn't get worst.
I would appreciate if you can let me know!

I followed your tip, but in my 950F, exynos, this app in fact decreases the volume! It may only work with snapdragons

Mixer_paths.xml explanation

Hey everyone,
I'm running AEX 6 on my Zuk Z2 Pro, but I'm noticing that during calls, especially with Skype and WhatsApp, the volume is too high. I have them already on their minimum.
I searched the net and found out that I can modify the mixer_paths _tasha.xml file to reduce the volume. Unfortunately, I couldn't figure out what all the "paths=" mean and which ones I have to edit to reduce the volume.
I need to reduce:
1) In call speaker volume
2) In call headphone volume
The normal volumes, ex. when listening to music, are perfect, just in-call the volumes rise automatically even if android says they are low.
I'm looking forward for your help ?

im also trying, in oreo this is impossible i think, system wont react on any values i put in mixer path.
in nougat roms i just edit rx7 value, but in oreo this wont work.
you can also try some kernel editor, and there should be some section to adjust sound levels if kernel alows for that.

volume steps to big / media volume sync off?

I have a sony z3c with a broken microphone. So I thought, I can use this great phone as an music-, podcast- and audiobook-player. Just ike the Sony NW A100.
But when I connect a bluetooth speaker or headphone to that device there are only 15 steps to increase or decrease the volume. And the lowest volume possible is way to loud to listen podcast late at night on my JBL go 1 or 2. Also the volumechange between two steps is to heavy.
Normaly I use my Samsung Galaxy S8 to play audiofiles. There are also only 15 Steps to change the volume. But I can change “media volume sync” in the bluetooth advanced settings to change the volume of the smartphone and the speaker separately, which fixed my problem. On some sony smartphones in the developer options you can toggle "Disable absolut volume", but on my z3c this option is nowhere to be found.
But that’s not possible on the z3c. I tried apps like “Precise Volume“, some tweaks in the Xposed framework and ViPER4Android. Even some custom rom. But nothing worked.
With some tweaks or ViPER4 Android I could get the volume lower (by reduce the output gain or lover all frequencies in the EQ). But then, when I change the volume, sometimes 2 or 3 steps remain on the same volume.
Does any of you have any Idea how to help my with my problem? It’s been two month now, that I tried everything to fix it, but till today, I don’t found any solution...

idk exactly, but maybe you can take this a hint for furter research on that topic:
