Bluetooth or jambox don't know - OnePlus 2 Q&A, Help & Troubleshooting

so here is something odd. I'm running oxygenos 2.1. I have a Bluetooth speaker and when I connect to it, my volume level on the phone remains fixed at about two thirds of max. the icon displayed is also the cast screen icon. this happens when I use spotifyto stream music. now if I switch to say tunein radio, it switches to a Bluetooth icon and I can control the volume as I wish. this is obviously a software glitch but has anyone else experienced this? I want to make the volume lower or higher and can't, hah.

[REQUEST $$$] Change media volume while docked and connected to car stereo via BT

$60 goes to the person who finds a way to get this working!
This is a random issue that I've been having that's driving me nuts. I have the N1 car dock along with a Clarion CZ500 BT car stereo and everything is working fine... BUT I cannot change the media volume over BT while docked.
Why do I need to? Because my call volume is terribly low and I'm constantly changing volume levels on my car stereo and occasionally blowing out my ear drums when I forget to lower it as the call is ending and the music starts up again automatically.
If I had access to change the media volume, I could set the BT media volume at a comfortable level (with Tasker's help obviously ) when the phone is docked and not have to ever adjust my volume!
I'm wondering if this is actually a PowerAMP issue, but I can't seem to test the issue properly because I can't find a music player with a volume control slider.
BTW, I know that this is a docking issue because when I'm simply connected over BT without being docked the media volume changes just fine.
I'm running CM7 nightlies for the record.
Thanks!
PowerAmp seems to have some minor issues with bluetooth. Or it might be the combo of that and CM7 as it does odd things at times for me.
Does your headset try to tell the phone how to change volume, or are you doing it from the volume control on the side of the dock? I find that the built-in music app lets me change the volume just fine from the buttons but that poweramp seems to be a bit temperamental about it. (Although there was an update today that may have fixed it, I haven't checked yet).
My car stereo doesn't communicate the volume change to my device, it just adjusts the stereo volume.
I'm not controlling the volume from the physical buttons because the only ones accessible are those on the dock and those aren't connected when you're not connected to the dock via BT. I'm controlling the volume using the volume slider on PowerAMP.
As I change the volume using the PowerAMP slider, I see the display for "Media volume playing over Bluetooth" and the volume bar changes but it doesn't affect the volume. The only time the sound gets affected is when I get to 0 in which case it mutes.
No one has any other ideas???
Mine just works with my Sony XAV-70bt. I set the volumes once, and it just keeps them working. So my suggestion, sell Clarion, buy Sony. Can i have my $25?
But seriously, a lot of these head units have a separate builtin volume for the handset profile vs an a2dp. Mine has a phone call volume, then a separate BT Audio volume. You might run through your settings, find a different media player, or try another rom/kernel. Are you connected via physical 3.5mm cable from the Car dock to your Clarion, or using a bluetooth connection to it?
BT. There are no volume settings that I can find for the specific profiles.

So you want to be able to control phone volume from the head unit? I don't believe this is possible at this point. I suppose someone could build an interface using the AVRCP profile that would control volume. In theory it's possible.

I just want to be able to modify the media volume when I'm docked and connected via BT to the stereo. It seems as if the OS blocks a volume change when docked and connected to an external BT and I simply want to override that "feature".
As I stated above, if I'm NOT docked but still connected to the stereo via BT, the volume can be changed.
I battled the same issue for a couple of months. Solution: Tasker on the android market.
I have it set that when I dock my phone the media and in-call volume both max out. As soon as I un-dock it everything returns to the previous levels.
It's even cheaper than your $25 bounty
edit: just saw your tasker comment...so do you have it installed? or is it still not enough workaround for you? I have my N1 connecting to the bluetooth on the dock for calls, but i also run a 3.5 line-out into the aux port on my radio for music
Ya it's installed. But I'm running through BT. That's where the problem originates.
Maybe try contacting the PowerAmp dev or leaving a message on the forum on his site?
My BT head unit is in the mail so if you haven't got a solution by the weekend I'll be wanting to try the same combination so I'll check it out then.

I don't think it's a PowerAMP issue. I mean, I get the volume dialog and it changes as I "turn the knob".
Does anyone know of another music player that has a volume slider?
So NO ONE knows of a music player with a volume slider other than PowerAMP? I would like to see if PowerAMP is the culprit.
Obligatory bump.
Alright, I'll pay $40. Someone please!
Dropping too low!
Geez, patience dude. It's not that critical.
To me it is. And as soon as it's off the first page it's lost for good.
It's just frustrating that there are so many good devs here and no one wants to lend a serious hand.
Best of luck to you. I discovered that the volume is automatically reset when the phone is in the dock, regardless of what you set it to manually (even if you change it while it is in the dock, it immediately changes itself back). What you might need to be looking for is a modification of either the car home app, or of whatever protocols are responsible for the volume change.

That's what I'm willing to pay for.

Auto-resets Bluetooth In-Call volume to a level that is really low.

When connecting my new $80 BlueAnt T1 headset, to my rooted Android phone running Bionix V with voodoo always resets the "Bluetooth In-Call volume" to a level that is really low. It seems to be dependent on the type of headset I use. On some headsets it's set to 100%, others to 0%, and others somewhere in between. During a call you can set the volume to a comfortable level with the hardware volume buttons on the phone, which persists during the same bluetooth session. However, once you disconnect and reconnect, the volume level is at it's "default" level again.
In the mornings, when I connect my bluetooth to my phone, I get a brief message "Adjusting volume for bluetooth", which denotes that there is some type of profile setting that is unique for that headset.
This problem can be very annoying when using a hands-free system for the car for example, because you always have to take your phone out of your pocket to adjust the volume, while driving. This issue creates a dangerous situation rather than preventing one. When receiving a call, I must now look at AND adjust my phone volume every time a call is accepted while I drive. The bluetooth in-call volume NEEDS a way to be set and retained, before someone is badly injured or worse.
The correct behavior should be that it stores the bluetooth in-call volume level for every bluetooth headset that is connected.
I've done some research on the internet, but it's very clear that many people are having this problem with a lots of different headsets.
It very well might be an Android problem, but that doesn't explain why I'm having this issue with the BlueAnt T1, not my other headsets.
I have a Samsung Vibrant with Android 2.2. Is anyone else having this issue?
Okay! It seems I found a workable solution (kind-of). I downloaded the free app 'Volume Locker' from the market. Volume Locker locks your sound volume levels inplace, to where if you accidentally change your levels, it puts them back in place where you locked them.
Now, what I did is I called someone using by bluetooth headset, I had to manually turned up the 'in-call bluetooth volume' then I activated the Volume Locker app.
Now, everytime I call out using my Bluetooth headset, I don't have to KEEP turning up the 'in-call bluetooth volume' that resets everytime I disconnect a call.
I hope the Android engineers who make these OS updates will recognize this BUG and develop a fix. For right now, I can use 'Volume Locker'.

Low audio volume after finished using bluetooth and turning it off

Did a search and didn't see this problem discussed...
My Moto X Pure has great audio volume by itself through its own speakers, until...
My problems arise after turning on bluetooth, connecting to something such as my car's radio or my Vizio bluetooth sound bar, listening to music a little bit or even a while and then turning off bluetooth and just using my phone normally. When I return to using my phone normally, my audio is so low. I can barely hear any notifications, lock/unlock sounds, music, etc. All volume sliders are still turned all the way up but still, low audio.
Again, this only happens after I've used bluetooth audio, stopped using it and returned to regular phone speaker operation.
The only fix I've found, and it's not a fix obviously, is to reboot the phone. Audio is back to normal, loud after the reboot. But then connect it via bluetooth to something and play music, stop, turn off bluetooth, the audio is once again verrrryyyyy low even though all volume sliders are all the way up.
Anyone else having this problem?
Android 6.0.0 here.

I noticed that the volume when the voice reads a message is a lot lower then say the map direction or music app, also when i receive a message the notification is blaring. I know its not a phone but an app issue just wanted to see if anyone else has issues with it. Oh also i feel like the Bluetooth media kinda skips or lags every now and then. Have you been able to get the screen mirroring to work?
Some of the AA volume settings are controlled by the head unit/car. The only way to adjust them is the change the volume while the sound is playing. I had a problem of the directions being too low. I just had to turn up the volume using the car's volume knob while a direction was playing.
I use Tasker to exert more control over the individual volume sliders. For example, the volume slider for Bluetooth is hard to get to (if you can find it at all). In Tasker, I've created a task in which if a Bluetooth device is connected, the Bluetooth volume is then set to the maximum level.

Ill give it shot, I mean i have the blue tooth turn to max and the AA message read back is blaring. How ever if im connected via USB then the read back is too soft if the head unit is turned down. I guess you cant always get what you want.

The subject's volume decreases by itself spontaneously

Hi all! Is there anybody alive here? I have a question to duscuss...
Has anybody experienced the following thing?:
It's something like it is for Bluetooth connected devices, when the phone decreases the volume automatically after connection. But in my case I have no any Bluetooth devices connected. Moreover, I don't use them at all. And the effect appears spontaneously(at any time while the audio is playing) when I use the youtube app, google podcasts app or any other application that plays audio. It doesn't matter if it has video+ audio or just only audio. And if I increase the volume manually after the phone decreases it, after some time it happens again and again. It’s like the poltergeist controls the volume of my phone. Any ideas?
