A lot of that will depend if your headphones can support those bit rates. Its 50% on the headphones. Could you set those options on another phone with this headset? Also, did you stop the music while changing bit rate?
EDIT: I just tried it on my phone with some cheap bluetooth headphones. The3 settings dont stick but I also know that these are cheap headphones that will not support some of the advanced features.
EDIT2: When I use a better set of headphones, with Apt-X for example, I can change the settings and they stick.

Thanks for the reply will play with the settings and see

Nothing works

I have also run into this issue and reverted back to stock because of it plus other reasons.
You could solve this issue (errr work around it) by using Tasker and configuring Tasker to toggle the settings in Developer settings for you when a BT device is connected. I haven't done it, but I know it's possible as Tasker can do almost anything with Root access.
Good luck.

Probably... But I don't know how to use Tasker ?

I have the T-Mobile edition. I had the same issue with my BeatsX, which use AAC. Audio was pretty bad.
I didn't find a solution to the problem despite researching for days, but when I flashed the international OxygenOS the issue seemed to have fixed itself, and my dev options show the headphones using AAC like it should.
I don't know if this would fix your issue, but that's my story with the same prob. Setting for example the AptX codec with my BeatsX doesn't work because, iirc, the codec isn't support by the headphones themselves. So the setting gets reverted. Maybe your headphones only support that specific codec as well.

Default Bluetooth settings

I'm trying to find out if there is a way I can automatically make my bluetooth use a default 'on' setting of having both handsfree AND stereo streaming enabled?
The reason is that I recently bought a Sony head unit for my car which is BT enabled for both calls and music streaming. It's superb and is really easy to use in that respect and works very well indeed.
The problem is though that when I turn on BT on the phone, whether manually or by a profile switching program, it switches on with a default of hands free enabled, but not the music streaming function (A2DP?) so every time I want to stream music in the car I have to go to Windows>Settings>Bluetooth, then activate the stereo streaming option in the bluetooth control app, and this is really frustrating and fiddly.
I just want it so that every time I turn on BT (no matter by what means) that both these BT options are enabled automatically.
I have a sneaky suspicion that it's an easy thing to do and I'm just overlooking it so apologies if that's the case! I have found a setting for "Connect separately to Bluetooth hands-free and stereo audio devices" and I have unchecked this, but it has not helped.
Can anyone tell me how to do this please? And sorry if it's totally obvious! If I can't do this with the default phone settings, is there a suitable bluetooth management app that would solve it?
On a slightly different but related note...
The other thing I really want with BT (as per other peoples threads on this subject) is for Bluetooth and Wifi to switch on every single time I plug the phone into a charger.
I've tried 3 different profile switching apps now, and whilst they are pretty good I can't get them to behave 100% how I want, but more importantly they all seem to cause a very noticeable increase in battery drain. Some are better than others but I just can't hit the happy combination I want to justify all the hassle of setting them up and having less battery etc. I wonder if mortscript can do what I need. Presume so, so I'll have to have a look into it.....
Thanks anyway!
Actually - apologies but I think I found a couple of useful threads about this now that for some reason I missed when I was searching earlier. Doh!

Need help solving audio over bluetooth issue

Did a search and couldn't find anything related to my problem.
I have recently gotten a SM-G950U1 variant of the S8, everything is working fine except for when the phone is connected to bluetooth. On bluetooth, all audio plays over the call channel versus the media channel. I've tried on two different cars and a JBL speaker, all with the same result. Turning off wifi calling helps this only slightly, as the audio is still muffled sounding unless I disable the "Call Audio" switch in each specific connection in the bluetooth settings. Obviously, ticking this switch off for the speaker isn't really an issue, but leaving it off for the car connections is a significant setback.
I'm just coming from an S6 that was on 7.0 that didn't have this issue. The phone is not rooted and I don't have a smart watch or anything like that. I did boot into safe mode and I think the issue was cleared up there, but was still active on my phone when I booted back to normal, with all of the accessibility options and permissions reset as a result. But other than the Samsung Sound Assistant app --which I deleted to see if it was the cause (it wasn't) -- I don't have anything that would change the way default audio functions would work, and I can't think of any specific app I have or a setting I may have ticked that would've caused this.
Have you tried using seperate audio settings? I think it might help...

Can't change Bluetooth audio codecs or

I got the Oreo update and in developer options you're supposed to be able to change the codec, samplerate and a few other things to improve Bluetooth audio. However when I select a codec it doesn't change. It defaults to aac. I wanted to use Ldac. Tried aptx hd and Samsung hd as well and they don't work.
I have the same issue. When you select for example, AptX, the settings don't seem to stick.
Any suggestions? Thanks!
Same here on S9+ cant change codec, always goes back to AAC

Try deactivating Bluetooth, then change the codec. Should work. Cheers
Which codec is best? AAC was my default.
Sent from my SM-G965F using Tapatalk
Apt-X is the best. That being said, the bluetooth device you connect too has to be compatible. Maybe that's why it switches back to AAC for you. (It sticks to apt X in my case)
Same problem here, it doesn't seem to stick. Even if I disable bluetooth. After closing and re-opening developer options it reverts back to SBC.
Any fix?
For me it only changed when a device was actually connected
Mine does not stay after I change it, it goes back to SBC.
Yo, everyone. I use a sennheiser gt 4.40 with aptx with s8. If you want to enable aptx. first go to BLUETOOTH settings, click the 3 dots. disable the duo bluetooth audio and then go to the developer settings, you will see it's working. but to be honest, I find no difference between these. LOL
Cheers

Finally! Disabling dul audio is what allows the setting to work on my Note 8. Using Forza Metallo headphones there is a VERY noticeable improvement when using aptx!
The audio codec is switching back from LDAC because your bluetooth headphones/speaker doesnt support LDAC. Same would be the case with APTX HD.

My problem is my stereo in my car is older and needs to use the SBC codec to stay connected with any reliability, but the phone automatically switches back to AAC when it connects to it. If I switch it back to SBC after it connects I have no connectivity issues but if I leave it on AAC it disconnects every 5 mins, won't display some track information, etc.
Duo bluetooth audio is not enabled, I have changed settings with both bluetooth and duo audio off. It will accept the change to SBC, but it reverts back to AAC when the stereo connects. The phone will not accept any change to any other bluetooth developer option either, when I exit the developer options and go back in they all are reverted back from my changes. Quite frustrating.

Just logged cause of this solution, thank you comrade, this solved the issue.
on the s9 plus u can only change to profiles whilst playing sound through the bluetooth headphones and only codecs the headphones support. when you re-pair it will auto select the best codec the headphones support anyway so no need to change it at all. i would leave this setting alone unless you want to dowbscale the codec (as it picks the best one for your bluetooth device)
Codec change on S8 does not stick
I have tried the dual audio status trick mentioned above for Note 8, but it doesn't work for my S8. I can select AptX in the developers section, but when you return to that section, the codec selected reverts to SBC. I have a pair of earbuds that supports AptX. Is Samsung pulling a fast one on us?

Worked for my s8. I am using it with a fiio q5. Aptx sticks after duo audio disable.
My S7 kept reverting back to aptx after I used LDAC With mij Sony 1000mx2.
There is an extra setting in the bluetooth settings for that headphone (tap the little)cog) to enable LDAC.
Switching that on worked for me.
where is this setting Dul Audio?

Hi all,
I can choose all the settings in my Umidigi A1 Pro but when connecting BT settings go back to default SBC. Android 8.1 has as far as I can see no more 3 dots or dual playback.

Samsung S8 Crackling Bluetooth audio and Bluetooth Codecs

Hi Guys.
I've seen a number of posts on this subject so here's my story and my experience thus far.
I've been using an iPhone 7 since it came out. I've been very happy playing music in my car (Fiesta with SYNC2 system) all this time. My significant other has been using an S8 for some time, and her music always sounded 'crackly' (for lack of a better word) in the car. I thought this was just her Spotify or something.
2 Days ago I bought my own S8 and I had exactly the same issue.
Now from some research I've been able to deduce that this is down to the Bluetooth Codec the phone uses. I changed mine to aptX yesterday and the music quality was great. Didn't sound like a 200KB MP3 downloaded in the early 2000's anymore.
However...
Last night I had to reboot my phone for reasons, and the developer options reset completely, which I believe is normal behavior. But now I can't set my Bluetooth Codec anymore? I change it, the moment I close the menu, it reverts back to SBC. I tried this with Bluetooth off, Bluetooth on and not connected, Bluetooth on and connected, no joy. It keeps reverting. Same goes for all the other Bluetooth settings (i.e bitrate).
So gentleman I ask you humbly, wtf? Why does the settings not stick and is this normal behavior? Is there a way I can force it to use AAC or aptX once more? I really have come to enjoy this phone but playing music in my car is a very very big factor and since AUX and USB (can't seem to play Apple Music/Google Music via USB) isn't an option, I'm stuck with Bluetooth.
Thanks in advance,
Have you made sure dual audio is disabled???
If not, go to Bluetooth, turn it on, hit the tripple dots in the top right and tap on "Dual Audio"
Make sure it's off and now try changing to AptX or whatever codec works best for you.
Disable / re-enable Buetooth and see if it sticks. (Try rebooting too)
Also, Bluetooth codecs will automatically change if the device you're connecting to doesn't support your choice of codec.
Keep me posted

Hi Corey,
Thanks for the response. Unfortunately, the above didn't work Dual audio was disabled, I enabled it and disabled it again. I tried changing the codec and bit rate but the result is the same, the moment I close the menu or turn on Bluetooth, it reverts back to SBC and Best Effort bitrate. I should mention that when I turn on the Bluetooth, it doesn't connect to anything, the only paired device at this point is my car.
Interestingly enough, if I don't close the menu but just hit the middle button, the settings will stay as is and the audio is great. What I haven't tried yet is closing the menu after a 'good' connection is made to the car. It may be that the setting sticks but the menu says otherwise. But I can definitely confirm that if I close the menu and then connect, the audio is garbage.
As for the compatibility of the car's Bluetooth, well it's a Ford SYNC2 system which from what I can see is actually quite basic. I am starting to this the problem isn't as much the codec, but rather the bitrate at which the phone is playing/sending music across the Bluetooth.

I'm not gonna' lie, I'm not very impressed by the Bluetooth on the S8... or Bluetooth in general.
It's lousy most of the time, mine always distorts and especially around emergency vehicles... (Could be interference from their coms???)
If possible, just stick to good 'ol copper wire
I can't imagine wireless audio not ever being interfered with and will always stay wired.
Also, try a music app called Poweramp.
It has many settings involving latency etc. It has a trial for 2 weeks and is worth EVERY penny if you decide to buy IMHO.
Try the build version first, if that doesn't have settings that you need, try the alpha version.
It has lots of latency settings etc
I'm guessing higher latency = better results as it has more time to be pushed over BT before the sound is reproduced.
I'm probably wrong though.
Can't beat lots of settings tho aye.

Morning Corey,
Yeah so my situation at the moment is to have my old iPhone in the car at all times as a glorified bluetooth player. I've also gone out and bought an auxiliary cable for when the iPhone's battery dies on me (happens more often than one would think). And to have a charger for the iPhone, charger for the Samsung and aux cable for the Samsung all plugged in becomes really messy.
It must be something to do with the Bluetooth 5 feature. I don't know what version the iPhone is (cba to check) but it works like a dream.
Wish we had some form of backwards compatibility or a feature to force an older version with Samsung. Just sucks buying a phone which is really not cheap in ZA just to have the music sound like a 300kb MP3 played on Winamp with the treble bars turned up all the way.
I'll try out the app you suggested mate, thanks!

No worries and if you are referring to a USB cigarette lighter charger/USB charger then try the multi-cables.
Try one of these: https://www.amazon.co.uk/Poweradd-L...coding=UTF8&psc=1&refRID=59QBSADVWM0NKGZGTQ4K
sorry to drag up an old thread, i have the same problem ( sync2 too) and it is same issues. I have noticed that even though its bad its tolerable bad. then i add my samsung watch and becomes awful.

Bluetooth sounds issues with car

Since moving to the S10+ from S9+ , I noticed the audio quality on the car bluetooth cracks at certain points. (Example, listening to Tron Legacy - Overture towards the end).
I have done some research and tried changing the codec but it always reverts back. I would have thought with the latest update this would have been fixed!!!
Anyone tried anything else?
You cannot change the codec. The developer setting is not true or real - it is automatically detecting what the car and the file are able to play to the phone.
I don't know why people think that matters.
My bluetooth has no issues with quality. How old is the car? Is it using like Bluetooth 2.1 or something?

My car is a 2016 registered car, i've connected my wife's iphone and the sound is better, i have also connected my s9+ (refurbished as the s9+ is an insurance replacement due to my s9+ being stolen and i am selling it) and the quality is better.
Maybe I should download the firmware and reflash?

One time a few weeks ago my sound was kind of quiet and I wasn't sure why, I eventually forgot about it but a few days later I was messing with settings in "Sound Assistant" and the regular system connections, and I did something with one of the controls like Media Volume Sync or maybe in dev settnigs for Disable Bluetooth Absolute volume, and everything got WAY louder.
Also, sometimes you may need to reboot after making those big changes just because any phone can glitch and not apply right.
If you don't have Sound Assistant it's in the Play Store and the Galaxy store:
https://play.google.com/store/apps/details?id=com.samsung.android.soundassistant&hl=en_US
I'd try looking at these things and enable\disable:
Media Volume Limiter
Media Volume Sync
Disable Bluetooth Absolute Volume (Developer settings)
Dual Audio setting\toggle
Dolby Atmos On\Off? Auto?
Let me know if any of those help I'll reply when I see if you quote me!

I've tried the Samsung app and the other options nothing improves the quality. I have downloaded the last firmware and flashed, still having the sound quality issues.
I have also updated the firmware on my car but that hasn't changed anything, but its definitely the phone that is an issue, i've even dug out my S7 and paired it to the car with no issues. When I connect the S10+ via aux the quality is much better.
