[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!

Bluetooth aptX with external speaker

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?

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:

Question The issue with the sound via Bluetooth in the Xiaomi Redmi Note 10 Pro phone.

The problem appeared after the update to MIUI 12.5.1 Global Stable.
The crux of the problem:
In Bluetooth headphones with the Dolby Atmos option enabled, the volume of music tracks changes all the time depending on the dynamic range of the composition (even if the "music" parameter is left), which is incorrect and distorts the author's idea. If you turn off Dolby Atmos, you get an unacceptable sound. Like the headphones are losing synchronization, the panorama is disturbed, the sound is very distorted, which is simply impossible to listen to.
Temporary solution:
Open the Sound Effects menu → Adjust the sound for headphones → Turn on and then turn off the function. If the "Headphone Volume Control" function is not available for wireless headphones, the following helped me: connect wired headphones → turn off HI-FI sound. Then repeat the steps described above.
This solution works until the subsequent switching between audio applications. The problem has a programmatic nature, and I hope to be fixed soon.

Thank you so much!!! I was desperate to fix this, now it works!

The Mi Note 10 has a weak Bluetooth modem. In our experience, simply using the device with Bluetooth headphones connected can cause audio drop outs. These occur randomly and even with the Mi Note 10 right next to multiple sets of Bluetooth headphones.

Yes I also face this problem many times in my Redmi Note 10 Pro Max,the sound volume fluctuates when connected to Bluetooth speakers or earphones, temporary solution is that you have to disable Dolby Atmos and use Hi-Fi Sound,it will not fluctuate.

Question Audio via Bluetooth is faint and lower volume

Dear users of Pixel 7, moderators and audience.
I have recently moved from a different Android device onto the newly Pixel 7 recently and I have noticed that my headset has a lower volume at maximum output from the Pixel 7 compare to my older devices.
Is this normal or is there a way to maximise the volume coming from the Pixel 7?

I'm fine with bluetooth audio on my P7, no difference comparing to my previous P6Pro or any other phone I owed.
Only in rare cases - noisy environment, low volume of original audio/video source - I use Volume Booster GOODEV https://play.google.com/store/apps/details?id=com.goodev.volume.booster.
Be careful, putting slider too far to the right will hurt your ears

Try disabling absolute volume and see if that helps...
Developer Options>Disable absolute volume>Enable

Hi Lugh! I tried this feature, it did help boost the audio, but losses control of the slide when pressing on the Bluetooth device.
In short, when I have "Developer Options>Disable absolute volume>Enable", my AfterShokz AS800 (headphone) has volume control. When I press them, the volume bar is not changing on the UI of Pixel 7, but I can definitely hear it going louder in the device.
In short, even if I slide the UI to 100%, I can basically boost another +100% which is a little strange... Any idea if this is a bug? Any idea how to submit bugs and glitches to Google?

When I disable absolute volume, I do two things:
1. Turn the Bluetooth volume level on the phone to maximum.
2. Control the volume from your Bluetooth device.
Otherwise it goofs my volume levels for my headset and car.
Also I use the magisk module JamesDSP so I can modify the output volume, effects, etc.
Mostly for the built in speakers. They're either too loud or too quiet. At night, I reduce the post-gain, so that media etc doesn't bug people around me.
Hope this helps
