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!

Hi,
When pairing up with a Loewe Speaker2Go Bluetooth speaker using aptX my Sony Z3 compact defaults to max volume and the volume control is not configurable from the phone (I am aware this is a KitKat "feature"). The main problem is that this only allows a small scale on the speaker between no sound and very loud sound (3-4 volume presses). Has anyone experienced this kind of problem with other speakers and is there a solution? Thanks,

I paired a Bluetooth Stereo Headset, LG HBS-800, has aptX. When they are connected, I can press the volume rocker on the Z3C and it'll pop up a Bluetooth Volume. My headset has its volume control and works independently.
Yeah, same on my Sony Bluetooth Headphones. Volume control via volume rockers both on phone and headphones (independantly).
My SuperTooth Disco 4 Wireless Portable Bluetooth and NFC Speaker when connected, I get a Bluetooth Volume slider. Apparently it uses the aptX protocol too.
No issue here with the Definitive Technology Cube. NFC, Throw, AptX, and Bluetooth all works together in harmony.
It's a bit of a shame for the OP as that item is pretty expensive that it does that, when much cheaper speakers don't. Odd.
It is a shame as the speaker is very good and worked perfectly with earlier versions of android. Based on the compatibility list it has not been tested with 4.4+ though... Based on the previous replies I guess it is not a sony problem as other Bluetooth aptx devices can still be controlled from the phone. For the devices this works with is the volume in sync on the phone and speaker?
My speaker is controlled entirely by the phone, it has no volume controls itself.
Ok, this seems to be an issue with the Loewe speaker and not the Z3C. I've just been to an hi fi store and tried pairing the phone with a number of Bluetooth aptX speakers, including AudioPro T9, AudioPro T10, Marshall Stanmore and the Sony SRS-X9 and with all these devices I could control the volume from the phone as well. Will check one more thing on the Loewe when I get back home - it had phone and media pairing on (not just media like the other speakers) so maybe this is the problem. If not, looks like the firmware on the Loewe does not support Android 4.4+.
I am having a similar issue but it presents itself when going above the 4th notch on the Bluetooth volume on my XZ3C. Volume goes from 0% to %15 to 30% to 80% to 60% and 70%. When my computer connects to the same bluetooth audio dongle it has a smooth range. I suspect it is a problem with the XZ3C protocols that interfere with certain bluetooth devices and not a hardware problem.
I have the same issue with my JBL speaker. I can't change the volume on the speaker without the Bluetooth volume on the phone rising or reducing. It seems that there isn't any independent control using my z3 compact but if I pair it with my LG g2, it works independently.
Same here with the Jensen Scandinavia Buddy. My Z3C cannot control the volume but my Galaxy S2 running Cyanogenmod at 4.4.4 can.
Still an issue after upgrading to Lollipop.
the good, the bad and the funny
Xperia Z3 Compact, Android 5.0.2
I connect my phone to a Philips BTB 7150 home audio system.
- the phone does not change the volume of the audio system upon connect (good)
- i cannot control the volume of the audio system through the phone's volume rocker (bad)
- when i change the volume directly on my audio system whilst connected with my phone, the phone shows the Bluetooth Volume popup and the slider moves in sync (funny)
So there seems to be some kind of control connection, but only one way.
On the other hand: no problems with iOS devices here. When connected to an iPhone the phone controls the system's volume and system volume changes are reflected on the phone's volume setting.

Xperia Z3 Compact D5803, Android 5.0.2 (Nordic stock ROM, no hacks)
Home hi-fi system with Philips BT adaptor: phone can control the BT audio volume output (as expected)
Home mini hi-fi system: phone can control the BT audio volume output (as expected)
Car BT audio system: phone can control the BT audio volume output (as expected)
JBL Charge BT speaker: phone cannot control the BT audio volume output (oops) ; I need to use the speaker's volume control
So, quite a few gadgets work well, but in fact my JBL speaker suffers from the same problem, which I never realised before.
Is it a speaker BT standards problem ?
Or is there something in the phone's BT implementation that needs refining ?
Same Problem here
I have the following problem:
I use the Z3 compact with a Sony BM-10 BT audio receiver. When a make a call with my BT headset which is not set to maximum volume the volume of the music is set to maximum from time to time afterwards. Also the volume slider shows the BT symbol or loudspeaker or the throw symbol randomly. I tried many things to solve this as pairing the BT devices again. Anyone any idea?
When my phone is connected via Bluetooth to my car's hands-free kit, some audio could do with being made a little louder.
For example the navigation prompts from Google Maps are plenty loud enough, but some audio-book MP3s played via MD Player and phone call audio could do with being a bit louder.
I have the volume on the Note 8 and the hands-free kit on maximum.
Is there a way I can apply an audio boost when connected to that particular Bluetooth device (or have it controlled via Tasker)?
There seem to be lots of audio boost/control apps in the Playstore, but many seem to allow control of volume for a device without the ability to boost the volume above "normal".
I tried "Precise Volume (+EQ/Booster)", but the boost function didn't seem to make any difference.
If it makes any difference, I'm using Android Auto when connected to the car.
Bump - Anyone?
the only app in the play store that I have found that actually boosts the volume on this phone without being rooted is one called "volume Booster Goodev"
be careful, though, as it can really crank the volume up..
Thanks for that .... had been looking for a volume boost on the headphone out without rooting and this seems to do the job perfectly.
i have 2 different sets of bluetooth headphones over the neck.. one is bluetooth 4.2 other is 5.0 evertime i go to use them its at 50% volume.. i have checked and recheck ever setting pertaining to volume audio and bluetooth.
It's to protect what ever your connect to. Have you turned on your car and your radio is still atthe volume you left the car previously at and it scared the crap out of you?! Having it set at 50% saves both speakers and your ears.
There's a thing in android nowadays where it'll learn the volume preference per device you connect and next time you connect also it'll start from there! I don't have this problem for my car and I've not noticed on my earphones as well... When my phone is connected to the car, it's at 100% always!
You could use Bixby Routines to set a pre-defined volume level when you connect to specific devices, as well as any other changes you'd want.
I have it max-out the volume when it connects to my car, since the car has separate volume control.
I recently got this smartphone, and one of the very first things that I noticed is that volume thru headphones is very low, this affects the 3.5mm jack, USB-C audio and even bluetooth. It is in fact much lower than on the previous Redmi 9 which I compared with.
Doing some measurements (by playing a tone and measuring with a multimeter) I found that if I plug a male to male 3.5mm jack to the headphone, it will play audio thru, however none of the settings for headphone will be enabled (meaning that the phone doesn't think that I'm using headphones) if I then connect headphones using an adapter it will play at full volume no problem.
The 3.5mm2 jack puts out 0.8Vrms when there is no headphone, and 0.25 Vrms when it detects headphones. (way too low for many headphones).
This means that the phone has a feature that lowers its max volume by 10 dB when using headphones, that is why it also affects bluetooth audio.
For those that want to test it, if you plug a 3.5mm2 extension cord to the headphone jack, and then you plug headphones you will find out that the max volume is much much louder.
Hopefully there is a way that I can remove that feature all together.
I already tried changing the region, disable absolute volume, etc. None of that worked.
Follow up:
I found that what causes the problem is the equalizer effect that Xiaomi added to the phone.
Every time that the smartphone detects headphones it enables the equalizer, the equalizer has a range of +10dB and -10dB.
They implemented the EQ in such terrible way that +10 dB is actually -10 dBFS and -10 dB is -20 dBFS.
So if I increase the volume at say 100 Hz, it is now able to output 0.8 Vrms at 100 Hz. However if I increase the volume in all bands the EQ does nothing and it stays at -10 dBFS. meaning the issue is still present.
There is no option to disable the EQ, it is just flat by default but they didn't add an option to turn it off.
Edit: I tried disabling com.miui.audioeffect thru ADB and while it was disabled, the volume is still low.
No idea if there is another APK that I could try.
