Increase bluetooth volume - OnePlus 7 Pro Questions & Answers

Is there a way to increase my bluetooth volume? I've paired three different earphones but the volume is very low in all cases. I've rooted my phone so I'm wondering if there is a tweak I can install to fix the maximum volume block.

years ago I did this on rooted Motorola phones by simply editing an xml file. You might hunt in the forums for the phones I've had.
I assume you messed with the bt settings in the developer options

How to increase the speaker volume ?

Hi Guys,
I find the volume is too soft when the phone is switched to a speaker mode. Anyone knows how to change it ? the System and Ring volume bar is already at max.
I used to owe an Omnia...but sold it off because i hate the touch keypad.
Omnia has this code *#0002*28346# that can change all the speaker, earpieces and ring tones.
Does TP has similar code ?
Look for solutions...thanks

I think there is no resolution for low speaker/headphone voice level yet...
yeah no solution as yet...
The sound volume is also a bit lower,that I am using normally(another HTC devices descibed below). I was all the time very happy with HTC's loudness,but Raphael is really too silent. Only one solution now I see,turn on speakerphone mode and turn the device around.with the display outside. So you can call also in discobar.
Sad..Sad...

Guys there is a way to edit the registry on a touch pro to make the volume louder, I had it on my old touch pro, but I just had to get a new one from the insurance company. As soon as I find it I will post it here
I just got my Fuze a couple of days ago, and noticed how much lower than my tilt the speaker volume was. I was ok with it, but is nice to hear someone has a reg hack for bringing the volume up on it. I'll be waiting for this post!
HKLM/Control Panel/Volume AND HKLM/Drivers/Speaker both potentially affect volume
or try this cab, it should work, havent tested it tho
On GSM devices, there is a set of AudioPara*.csv files which are normally found in the kitchen OEMDrivers folder - the contents end up in the .\Windows folder as hidden files). Use the device File Explorer (show hidden/system files) to confirm that AudioPara*.csv files exist on your CDMA device.
1) If they do exist, search the XDA forum using these keywords:
Arup Audio Boost CAB
2) If they do not exist, a CDMA chef may be able to offer some insights on how volume levels are handled for CMDA devices ... afaik, should be the same.
Using a registry editor, search for the .CSV file(s), it will yield the registry key that may need to be changed if you wish to point to a different .CSV filename in case you wish to return to the default file without resetting your device. In all cases, be cautious, tweaking the AudioPara to extreme ranges can damage the device or your hearing.
HTH,

[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...

Disable Absolute Volume Developer Options feature doesn't work in Pie

Just got Pie on my pixel 2 xl. Since Bluetooth Volume control is horrible on pixel devices (i.e. Volume level 3 too quiet, level 4 too loud, annoying) I was pumped to find the "Disable Absolute Volume" developer option in 8. In Android 8 that option would allow for more precise control of Bluetooth volume since it separated Android and bluetooth device volumes. Well, in Android P that option is still there but DOES NOTHING. Changing the volume on the BT headphones also changes it on the Pixel. I have tried all the usual tricks like removing all paired devices, rebooting, etc. Argh. Anyone know a trick to get this working again? If not, does anyone know of an app that can achieve this without ROOT? (I use Anroid Pay a ton and don't want to root and lose that).
Got the same issue on xl2. I was told that it works, but the behavior changed. It is now intended to disable or enable individual volumes for each connected device, as opposed to separating the headset volume rocker from the phone's volume setting. Sucks on many levels, not much can be done about it.
Thanks for the response, but NO WAY

Thanks for the reply, but I can't see how what you are saying is accurate. 1st, the saving of individual bluetooth volumes has been widely reported as a new feature in Pie, and I can't find anywhere that states that the feature has to be turned on or off in Developer Options.
Even IF what you are saying is true, there is no way they would bury a toggle for saving bluetooth volumes in the Dev Options, AND hijack a feature named "Disable Absolute Volume" to control it. That does not make any sense.
"Absolute Volume" is the "feature" that ties changes to the volume on a bluetooth device directly to the phone (or tablet) volume. They wouldn't dig into the code of the "Disable Absolute Volume" and totally change its' function but not change the name.
Okay, first, the use of all caps is unnecessary. Second, it’s not a matter of what I’m saying as true or not true, as I stated in my post, I was told, plain and simple. I’m equally frustrated about the button not working, it’s messing with the audio quality for sure. Good luck finding answers.

Don't want to get into a flame war here, and I really do appreciate the response. I only all-caps'd 2 words for emphasis. I stand by my thoughts above. I would have to guess that whoever told you was mistaken, since it really makes no sense.
Agreed, and yes, it does suck because the volume is a mess. Hopefully google fixes it soon. cheers.

Bluetooth headphone volume

Any devs out there know how to adjust Bluetooth volumes like you can do with wired connections via mixer paths xml files? I've looked everywhere In the file system and found nothing.

Maybe the Bluetooth hardware on headset is responsible for volumes not the phone. You can change profiles in developer options try changing and see if you found something working.

Yea ive tried all of those as well, posted here to see if any dev has an idea but you're probably right. I wish they didn't get rid of the damn headphone jack.

Just to make things clear are you trying to boost the volumes or equalizer?? If that the case then viper4android does that job.

Boost music volume?

Hey guys!
I’ve been running my Note 10 plus stock since I bought it and I feel it's now old enough for a custom rom.
My biggest gripe with the phone is that I am unable to list to music LOUD with Bluetooth headphones.
I have the normal volume limiter disabled but I am sure it would be able to boost the volume even more.
A couple of years ago when I owned the LG V20 I had the phone rooted and was able to edit and XML file if I remember correctly and could boost the volume to any limit I wanted.
Is there a rom or any other option that let's me do this on the Note 10 Plus?
Thanks in advance.
