Anyway to Lower Volume?

hi i have a xtrons PF75AA4A headunit. everythings works great in my audi a4 cabriolet with bose system. i have rooted the unit and installed viper4android so the audio is better than what is was before. The only issue i have with this unit is that the lowest volume "1" is set too high. i would say volume 1 is equal to like 8 or 10 on normal car systems. i cant seem to find an option to lower the volume. if i put the car in reverse than the audio levels go lower but this is cause of parking sensors. Its annoying when im driving and want some ambient music but the lowest volume is too loud.
any help would be appreciated.

the std sound out is fine to power a normal sound system, but the Bose system requires an UN-amplified sound input I have the xtrons in my Silverado with the Bose sound system once I got the AMP powered on I had FULL sound for lack of a better term, then proceeded to cut the speaker out(s) on the harness and added rca male/females to the sound in adapter from the back of the xtrons unit to get sound volume that works. It's been fine since.
quote from a guy on a truck forum
the stock head unit from GM that are Bose the output from the unit to the amp are NOT high level speaker outputs like your regular non-bose head units. instead they are low level rca signals

in Joying in Factory Settings there is a way to adjust volume levels

**** i'm looking for a way to turn it up!

I see that this thread is for lowering the volume, but the fix would be the same if someone needs it to have higher volume by default.
When the HU first starts it always sets the volume to 14 or 15 i think......WHY??? i want it to stay as i left it before shutdown. I don`t think any of the android phones changes the volume when you do a reboot. There are some volume settings inside the "factory settings" menu, but when you change the settings it needs to reboot, and then the problem with no sound and no working buttons comes up, so there is no way to test it, as i have to do a factory reset to fix it.
No wonder there is no restart option by default...
I use my HU with the factory installed stereo "BOSE" with 3rd party AUX unit and i control the volume with my OEM stereo so i need the volume of the HU to be up to the max.
I hope someone finds a fix for this.

it sets it at 14-15 upon boot up to protect your ears.

yeah, i know this but still..... Maybe there is a way of achieving this. Now i remembered that there is as app on the market- "Liama" that you can use to do various settings changes when certain conditions are met. This might do the job.

Any way to keep the volume before the car was turned off. My head unit suddenly gets loud when the car is restarted

Factory settings/other/boot default volume. Default is "no" which persists the volume from last use.

Well my problem is intermittent. Lots of time my head unit would restart with the last set volume... other times it would go to 15

I only have these options in my factory settings

How would you find out what you have and then ask those that have your unit?

Bluetooth Audio low volume

Anybody have a solution to this? I've tried u sing media volume sync and it helps a little bit but the S8 has much lower volume on Bluetooth overall than any other pho me I've used in recent memory. Doesn't matter if I'm using my headset or in the car.

Do you have the volume on the phone turned up??

I've noticed some anomalies around bluetooth audio volume as well. For instance, I can be running Waze and Pandora on my car or though my headset on my motorcycle. Volume settings are maxed out on the phone, with the final master volume being either my headset dial on the bike, or head unit volume control in the car. Pandora never seems to be at quite full volume and just after Waze finished speaking a notification, Pandora volume will increase for a fraction on a second and then be reduced again. It's like there is some type of limiting going on and I've disabled all limit settings that I can find.
This is not just related to Pandora, but other streaming apps as well. And without Waze running, I don't notice increased volume in the streaming apps. Waze just seems to somehow enable the short period of increased volume.

Let's see if we can solve this once and for all. I've been experimenting and I am having some results. But does require an equalizer app. I am using Equalizer FX so I don't know how these steps work on other ones.
Open the app, click the three dots in the upper right > Settings > check "Global audio output mix" it's description reads, "Warning! It does not work for new devices. We do not recommend to use this feature. However this is the only solution for some players." (I am using YT Music)
After you turn that setting on, go back and click the middle tab "Effects" and you'll need to turn on "Loudness Enhancer" then use the slider to adjust it to your personal taste.
You don't even need to have the main page equalizer turned on. Just the main toggle needs to be on, the one right next to the three dots.
This part is just a little extra for those who don't understand the issue. SoundAlive maintains the media volume separately from all other device sounds. In the past we just used Package Disabler, turned it off, boom no more limited bluetooth music volume. Now it seems, it cannot be disabled with going rooted. *Flips table* You can easily demonstrate the issue by making sure you have setting on for the device volume synced with bluetooth volume. Connect to a bluetooth speaker, play a song, then plug and unplug an aux cable into the phone, you'll notice probably a 30% volume difference.

I've noticed the same thing running Waze, it's like something is limiting the output.

FWIW, I've also noticed the same behavior when the phone is connected to my car stereo. I'll have to pay attention to whether it occurs with other devices. I suspect the behavior will be the same. I can pause any playing music and then un-pause it and the music will start at full volume before the volume seems to get limited. I don't have another Android phone that I can try this with and I've never noticed such behavior with either Windows Phone or iPhone.

I can tell you my past Android phones didn't do this.. The last two were a Droid Turbo 2 and an LG G2.

I do usually have DriveMode (and sometimes Waze) running although I've run experiments without it with the same results. There just seems to be some sort of limiter being applied.

S8+ Low Bluetooth Volume

I've got the same problem with my S8+. Samsung support simply say try resetting the phone, but as the problem was there from new, what difference is that going to make! It seems to be a fundamental issue with this particular model (8 & 8+), as my iPhone7 and my older Note4 don't have the problem.

Same here. I use V4Android, as it's mixed into the CarHDROM v9, works excellently to overcome the system low vole on my 8+

I m not sure if a solution... But I tried disabling Bluetooth Media Volume Sync ( Settings - Bluetooth - Options (3 dots on the top right) - Media Volume Sync - (Turn off) )..
This gives phone media its own volume and the bluetooth device to control its own volume.
The volume is better after this for me.

I'm having the same issue, but I don't have the option for Media Volume Sync as apparently my car's stereo doesn't support that function. Any other ideas on how to get this fixed?

you might be misunderstanding the original poster. I have the s8+ and I did what he was talking about on the phone. On your s8+, you go to system settings -> Connections -> Bluetooth then if you tap on 3 dot top right menu, you will see 3 choices: Dual audio, Media Volume Sync, Bluetooth control history. If you tap on the media volume sync, it will be on but blacked out so that you can't turn it off, so what I did was in that menu select dual audio and turn that on. It will say it has to shut off media volume sync yes/no - select yes and media volume sync will now be off. Then just turn back off the dual audio and media volume sync will still be off.
Sorry that was long, hope it helps.

Fixed!

Thanks! This pointed me in the right direction, although my solution was just the opposite. Turning this on solved my problem. Just a week ago my S8+ had no issues with Bluetooth volume. But I sent it for repairs and they updated the software. After that, the max volume on my earbuds were a whisper. Turning Bluetooth media volume sync on brought it back to previous pre-repair levels. Maybe it works in my case because the earbuds don't have any volume control. I don't recall ever touching this setting previously though.

I also had surround sound on , turned that off and it helped. Sorry if I missed this somewhere earlier in the post.

Grad it helped. However, it seems that i am also back to square 1 after some recent update... Bluetooth audio is just whisper to me now... Specially for videos (be it a video on ur phone or youtube, etc). This is happening to me with a Samsung s8 and a Samsung Level U !!! Reported this to Samsung. Lets c what response i get for it.

Go to settings /general management/ reset/network reset. After this I had to re enter Wi-Fi password but it fixed it. Not my fix found it on YouTube but it works.

Extremely low Bluetooth volume

Hi,
I have an issue with my Samsung Galaxy S8+.
If I try to play music via bluetooth to my speakers, the volume is very very low. The settings are on max and media volume sync can't be enabled.
I tried playing music with my Samsung Galaxy S7Edge and the volume was completely normal and very loud with nothing changed on the speakers.
I also tried this: https://forum.xda-developers.com/galaxy-s8+/how-to/low-bluetooth-volume-car-fix-t3595530 with no result.
My BT speakers: https://www.trust.com/en/product/19367-tytan-2-1-subwoofer-speaker-set-with-bluetooth-black
My S8+:
Android 8.0.0
Stock
Knox triggered: 0
Never did any manual flash. Always just updated it.
Are there common reasons for this or good fixes? Or is it just a software bug?
Thanks for your time!

It's oreo, they messed up the volume and everything audio on oreo, no fix right now I'm going to make a topic to see if it's possible to downgrade back to nougat.

Not just an Oreo thing. I've had the same issue with the Bluetooth in my car as well.

it's amazing that you can't tell the difference at all, it's very noticeable, i am unable to hear anything when i receive calls in my headset either, this latest oreo update is broken.

found something online, it's something to do with media sync, try connecting the bluethooth device, then go to settings, bluethooth, 3 dots and select media sync, select on and make sure both phone and headphones volume is max and restart phone, anyone notice any difference? i'm testing it now.

Yea that was the first thing I have read about when I started searching for it. I wanted to try it, but it seems like my BT speakers are not compatible with it. It says that it isnt compatible when I try to activate it. Not sure if there is a workaround to make it working.

I don't think this is an Oreo specific problem. I've encountered this bug since marshmallow.
The only way I could get it to reset the volume back to max was when I used crdroid.
The volume would get set very low. I could open the global equaliser via Google music. And the volume would not change.
I would then access the global eq via another music player. Just make a tiny change to any parameters and boom. The volume is now set to the correct level again.
The moment I would use Google music to access the eq the volume would jump down again
My tablet is now on naosp and the volume issue has popped back up.
Doing the same procedure will reset the volume correctly.
It is rather annoying to have to do this.
I don't know what is causing the problem but it looks like the global eq ultimately effects the output volume disabled or enabled

No difference at all with three different devices I connect to. I do have media sync disabled already. Hopefully you get it figured out.

I've done a test on my S8+ now.
I downloaded the latest firmware and flashed it with a complete reset of the phone.

After the flash of it the BT issue is gone. This was done yesterday (4/10/2018). I will report back if the BT issue returns OR in like 2 weeks+ if everything is still fine.
GL everyone

new firmware released by samsung, lets hope this fixes the issue :S, i checked the notes and it does say fix for bluethooth.

do you need root for that though and i never had this issue in nougat, this issue first happened in oreo.
And i have a universal eq setting on a separate app called precise volume which does the same thing.

It dosn't work anyway, still the same, on a good note they have fixed the low volume for incoming calls on my headphones, just the music volume is still crap.
I think my only solution is another set of headphones that support LDAC but they are £300+ lol or to get a Microsoft music player, i have a laptop that even beats what the old volume was on nougat so maybe a Microsoft music player would be a good idea, gonna look around.
It was good while it lasted i guess.

I wasn't rooted before but since then have rooted via magisk systemless root. I can still use pay and bank access etc...
I'm using viper4android now and have also disabled the system EQ.
I have just got connects2 for my car last weekend.
On the odd occasion the volume will drop when opening automate(the driving launcher) which is set to launch playmusic on Bluetooth connection.
But as soon as I swipe down the volume jumps back up.

Yeah for sure but be aware you might loose functionality on apps like banking and payments.
I use magisk to hide root so I can still use those functionalities.
Make sure you read into it first.
I've had a replacement connects2 module fitted today and all is going well.
Viper4android my EQ is absolutely amazing in comparison to other EQ and in my case the volume issue has been solved.
Actually it's really loud as I was used to the lower level.
Steps I took.
Unlock bootloader ( wiped my tablet)
Flash magisk
Install magisk manager
Added selinux module via magisk manager
Added viper4android via magisk manager
Disable global EQ
Set selinux to permissive
Install viper4android driver. Prompts when opening the app for the first time.
Reboot
And it's all good.
The bug with AutoMate seems to be tied to my maps speed prompting notification voice.
If it does revert to no EQ, I drag down from the top bar and it's back up again
I hope it works for you. Plus you now have a very awesome EQ as a bonus

Try enabling Developer mode (press Build Number 8 times). Then turn on Disable absolute volume. This de-links the phone volume control from the headset's volume control. Now you should be able to increase volume on both independently.

THANK YOU SO MUCH FOR THIS. I had two pair of bluetooth headphones. A Cheap pair with volume control and a fancy pair of JBL Frees with no volume control. I could NOT figure out why sometimes the volume was great when they connected and other times it was VERY LOW all the while the cheap pair sounded great when I turned them up. I was at wits end blaming JBL and Samsung when it was a setting for Bluetooth devices.
Thanks again Huyi. Very glad I found this post.

Audio volume issues

So I've got a weird situation here, play back volume for wired and bt Earphones is low, but if I pause a song and hit play again the volume is loud in the first milliseconds.
Also if I am hearing something and activate screen record also I can hear loud, so it seems software issue and I can't find a way to fix it, and I need your help.
I am currently on emui 11 and I think I had the same problem since emui 10.
Already tried bt settings on programming mode and also with dolby sound app (tbh I can't find any difference with the dolby on or off)

No one with P40?

Android auto call volume issue

Had the find x2 pro for a while now and has been fine but have noticed an issue with the volume of calls using android auto and how I'm picked up on the microphone of the car.
I was running a test as I'm with O2 and the signal kept dropping at certain points, so I plugged my work iPhone 12 Pro in and noticed that the call and music volume was much louder aswell as not dropping the call at any point in my ride home (Vodafone).
So I found my old phone from a few years ago which was a oneplus 6, let it run all the updates and plugged it into my car (71 plate suzuki swift) and low and behold it was the same volume levels as the iPhone and much easier to be heard on the microphone so its either a setting somewhere on the oppo or it is just crap with AA. On the oppo I have to set the call volume to 30(max) in the car but with the oneplus and iPhone it was 20.
I have tried turning off use high quality audio in the Bluetooth setting for the car and disabled absolute volume in the development options which has helped the volume of music but still way too quiet on the calls.
Any suggestions of any other settings to turn on/off as I'm close to binning the phone off

Might have sorted it.
Turning absolute volume back on has enabled media volume sync which was greyed out and now its much louder

Update, nope its not sorted so I'm gonna get rid of the phone come January
