bluetooth codec not staying - Samsung Galaxy Note 9 Questions & Answers

US at&t 9.0, unkodified. I can select bluetooth audio settings in developer mode butnthey revert back to default upon disconnection. Any way to make permanent?

Not yet it seems as others have reported the same issue

This is my default Bluetooth Codec on ATT official Pie update. I never checked this on 8.1, does anyone know what it was set to on 8.1 and is this what you guys are talking about?

Here is my snapdragon SM-N960W stock Bluetooth settings on Oreo v8.1.0
Mine revert back to this any time I try changing them. Only one that sticks is Bluetooth AVRCP I can run it from 1.4 up to 1.6. The rest always revert to the same as yours. See my stock note 9 screenshot.

Bluetooth Codec only sticks if an bluetooth audio device is connected and if this device also supports the selected codec. Else the codec always reverts back to sbc.
When I connect my bluetooth headphones for example it switches automatically from sbc to abtx, as this was the codec I last used with this device. Same with other devices and codecs.

note 9 with Sony WH1000 XM3
Just found that if you go to the Sony app:
Sound quality mode = Priority on sound mode
Then go back to developer options the bluetooth audio codec jumps to aptx and stays there.
Not as good as LDAC but better than SBC.

Aptx codec dont work on Oreo keeps reverting to SBC.

Is Aptx codec enable on Oreo?
Every time I change it it keeps reverting to SBC but my headphones are aptx HD compatible....any ideas?
That's because the Note 8 supports just Aptx and not Aptx HD

Thanks for your reply but not relevant because it should work fine hd or not....
And it's the same whith the Sony codec, none sticks and notice that when you change the codec in the developers zone and then you just start Bluetooth without any device paired it reverts to SBC automatically. Someone is able to change it?

In fact, at least for me, as soon as it connects to a paired device it auto selects the compatible codec.
For my MacBook pro it's AAC, for the Sennheiser Momentum is aptX, for the Bose SoundSport wireless is again AAC.

What BT device are you connecting to? For my Sony WH 1000x I have to select LDAC manually as it uses Aptx by default.

Did you try Developer Options.
I checked also I don't see BT codec option in the BT settings. Only available from Developer Options.
Edit: for LDAC I do get this option in BT settings so don't need to use Developer Options. Also Note 8 does not support Aptx HD.

Hi, after april update its working good....
Diference in quality sound is huge...thanks to who try to help me !
Do you have anything else connected to your phone via Bluetooth, at the same time? Like a Samsung Gear watch, Plantronics Headset, ...
If the second device is not aptx compatible the phone will stay in sbc on both/all devices.
I had the same problem but it got solved as soon as the Sennheiser Momentum was the only device connected to the phone by Bluetooth.
After disconnecting all other devices, stop then restart bluetooth. It should connect automatically to your headphones on aptx.
Hope this helps.
You can't enable it on a device that doesn't support aptx. if the device supports aptx it will be enabled automatically in developer settings. When you disconnect it will go back to SBC
You have to turn off the "Dual Audio" option in settings... Will work after that

Bluetooth dropouts when using stereo speakers

This is a long shot.
I have a pair of Bluetooth 4.1 Minirig speakers that can be set in stereo mode. However when in stereo mode one channel experiences dropouts. Running in mono mode is fine.
The issue is with the Nokia 7+'s Bluetooth transmission as when using other Bluetooth enabled devices to power the speakers the issue does not occur.
Anyone else had this issue when connecting stereo speakers or headphones and know of a solution?
I have checked: System > Developer Options > Bluetooth Audio Codecs and tried changing these setting but the changes did not "stick" and problem remained.
Maybe there is an alternative setting somewhere that can be tweaked.
Thanks in advance.

I'm also having this issue: whenever I'm connecting my N7+ onto the car's audio system via Bluetooth I have to change the codecs to the correct one every single time to make it properly work (have sound/audio at all). The settings also don't stick or are not being saved. Also looking for a solution for this, unless an update miraculously fixes it.
Same problem here when connected to my car by bluetooth. Occasionally there is a dropout. This does not happen when my friends connect with their phones (oneplus 5, samsung, allview. or my old lg g4).
Changing the bluetooth audio codecs does not work as it does not remain selected and it switches to default. This, as i understood, happens on android 8 and has been resolved in the Pie beta and should be ok in the final Pie release.
When I raised the issue with the superbly talented nokia tech support they either act surprised as if its an unique issue to you or send you a list of compatible bluetooth protocols. Are we expected to change our cars and speakers to make the phone work?
I had this issue after installing garmin connect. Theres a thread over in the garmin forums (forums.garmin.com/forum/into-sports/garmin-connect-mobile-application/garmin-connect-mobile-android/1375800-audio-streaming-issues) about it. Also on the nokia forums (community.phones.nokia.com/support/discussions/topics/7000022239/). Seems to affect some phones on 8.1
Anyway, I'm on Pie beta now and the problem has gone away.

Bluetooth codec on emui 9

Hello guys
I can't change Bluetooth codec from developer menu. I can only see SBC codec instead aptx(i have bt compatible headphones). Someone have same problem?
Known issue on emui8. Use search.
Done but anyone have this problem on emui 9
I use aptx on my samsung level u pro
this is normal for most devices. most android phones will not allow you to choose bluetooth codecs if they are not in use. even when they are in use, your options will likely be little to none. your device will choose the best codec that is compatible.

Can't Change Bluetooth Audio Codec

Why is it the Razer Phone 2 Bluetooth Audio Codec is SBC as default and no matter how many times I change it'll revert to SBC over and over? I'm using Razer Hammerhead BT btw.
The RP2 doesn't contain the licenses to enable other codecs for bluetooth so that's why when you change the setting it doesn't stick.
Maybe try this:

Is your device under android pie 9?
As for me, the SBC codec only happen after android pie 9 upgrade, when I first got it under android oreo 8, it can use AAC but no more than that, was told that Razer didn't get the licenses for aptx or any other higher grade codec. Trying to find out if we even lost the AAC too on android pie, or just my device problem......

Not yet in Pie, mate.
which means you couldn't get the AAC working even under oreo? that's strange......

{REQUEST} help me make a simple Module for permanently setting LDAC bitrate

Heyho! I've been researching everywhere but have not found a viable solution to permanently set the LDAC bitrate on an android Device. I have extremely basic coding skills, so I'd love someone to help me out and make this together.
PROBLEM
When using Headphones that support the LDAC audio codec (developed and support by Sony and Sony Headphones), many Android Devices wrongly default to a lesser bitrate (like 660kbit/s) or force you to use "adaptive bitrate (up to as little as 300kbit/s which is less than even inferior SBC)". Changing the bitrate to the maximum 990-909kbit/s setting in developer options often doesn't work and won't stick when the Headphones are reconnected or the phone is rebooted.
SOLUTION
A Magisk Module similar to "Bluetooth Audio Bitrate Changer" that permenantly sets the bitrate for the LDAC codec (not yet supported by the affirmentioned module).
Let me know if anyone would be interested. Cheers!
Same problem ..
have you found a solution?
Ward,still hoping someone would make it
Im going to ask for it again ;-;
PROBLEM
When using Bluetooth dongle that support the LDAC audio codec (FIIO BTR5), my Devices (s8/poco x3 pro) wrongly default to a lesser bitrate (like 660kbit/s) or force you to use "adaptive bitrate (up to as little as 300kbit/s which is less than even inferior SBC)". Changing the bitrate to the maximum 990-909kbit/s setting in developer options often doesn't work and won't stick when the dongle are reconnected or the phone is rebooted.
Any solution? This doesnt happen in my sony xz since it had option to override ldac sound bitrate from the sony rom itself

Solution: Install sony music center
I use samsung. It was same problem that in developer options it is defaulting to optimized connection.
But when I have installed sony music center app and in app options selected audio quality prefered on device after restarting phone now in developer options it is 990kb streaming is a default when connected to sony xm2.
I hate this as well. I do not fully understand why is this LDAC settings hidden in developer settings in the first place. You buy 400 bucks LDAC capable Sony headphones and you have to connect the BT, go to developer settings to change correct bitrate and frequency every single time as a complete moron.
If anyone capable can bring this (maybe simple) module to magisk I would make a statue for him
Hi, have the same problem.
On top of bitrate, I would like it to stick with constant 44.1kHz/16bit since that is about what LDAC can handle bandwidth-wise. But on my s10 it defaults to upscaling to 96kHz/32 bit, which then loses a lot of bits due to limited bandwidth.

I think you should not be able.
I've been searching everywhere for this functionality, but to no avail. However I've just found a workaround with the Sony Music Centre, so big thanks to whoever mentioned that. To be clear I'm not using Sony headphones. My setup is a Samsung phone and a pair of Fiio EH3's. I did it like this:
1. Installed the Music Center app
2. Powered up my BT headphones
3. Clicked on the 3 dots menu > Music Center Settings > Bluetooth Output Settings > LDAC Playback Quality > Priority on Sound Quality. This setting forces Optimised for Audio Quality in Developer Options.
5. Close the Music Center app. Note do not kill / force stop.
The magic bit is that I can then switch off my BT headphones, and when I switch them back on the 990-909 kbps setting persists. I can even reboot the phone and the setting sticks. The down side is that it also forces 96kHz/32bit. So I'm not suggesting its perfect.
The only action I've found that resets everything is a kill / force stop of the Music Center app. I then have to go back through the process of re-enabling the setting in the app.
Hope this works for others in their setups, at least until someone with the skills makes a proper fix.
Ahh tyvm bro

Thanks for the suggestion. Unfortunately it does not work with WH-1000XM4 and my samsung galaxy S9/redmi note 10; nothing I do seems to make the "optimize for audio quality" stick in developer options after I disconnect/reconnect. It always reverts back to "best effort" when I restart the headphone. Did anybody manage to make it stick with a S9 after disconnect/reconnect?
Alternatively, could you give me smartphone names where the "optimize for audio quality" sticks after a disconnection/reconnection ? Thank you vey much
Bumping this as my phone resetting it's LDAC quality setting when it reconnects to my car bluetooth every time I get in or out of the car is driving me batty. What's the point of LDAC if it defaults to a quality that is worse than SBC fer cryin' out loud?
I was also looking for an app or solution with same requirement , to set the LDAC properties to the highest setting when connecting to my LDAC Bluetooth receiver.
Bluetooth Codec Changer App does this.
Hope this helps.....
