Can't change Bluetooth audio codecs or - Samsung Galaxy S8 Questions and Answers

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.

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?

Sennheiser aptX HD
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.
Default:
avrcp 1.4
sbc codec
44.1 khz
16 bit
stereo
ldac default=best

When this was brought up before: https://forum.xda-developers.com/oneplus-5/help/whats-to-aptx-hd-aptx-sbc-bluetooth-t3627794
tl;dr set it to aptX HD and hope it falls back gracefully when not supported. No idea why it wasn't set as default...
I don't think the Bluetooth connection issue with your car has anything to do with the codec. Mine has trouble connecting every time regardless of what is picked. It is really frustrating, so hopefully it'll improve with a future update...
Depends on which codec your headphones supports of headphones supports aptxx

If your device supports Aptx (like some High-Rez Audio headseats), go for it .
If not select SBC
Aptx HD in only for Bluetooth 5.0 devices (actually no headsets or car audio system are available on the market with this feature)

Why not just select aptX[ HD] and let the devices negotiate down if it's unsupported?
Hmm my Sony XB650BT seems to connect using aptx hd. It doesn't appear to step down, but maybe it's playing aptx but still on aptx hd? The headset lists that it is aptx.

Unfortunately no because most of the time the AD2P protocol will choose SBC as the default codec if the codec you chose (aptx or aptx hd) is not compatible/available

As far as I know this is true and matches my experiences bouncing between aptX in my car and my non aptx Bose qc 25..

Bluetooth aptX not working

Hello everybody!
As I know our Nokia 5 (Android 8.1) supports Bluetooth audio codecs like AAC or aptX. So I want to use my Anker Soundbuds Sport IE20, which also supports aptX.
The problem is that I can choose aptX in the developer options and I can use it too. But I must choose it everytime if I want to hear music with my BT-headset. When I choose it, it works and I hear a difference to SBC and the same when I choose AAC.
So I want to ask you why my Nokia 5 doesn't choose aptX automatically, because it should do that (as I know)?
I hope somebody can help me with that
Edit: With my old Samsung Galaxy S5 it works perfectly without any problem.

Developer Mode Bluetooth setup not sticking... any solution?

As the title says everytime I setup my preferences in developer mode it reverts back after every song.... Is there any way to fix this?

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.

Does this device (Asus Zenfone Max Pro M2) support the LDAC Bluetooth Codec?

Hi everyone! I just bought the Sony 1000XM4 headphones. The headphones support SBC, AAC and LDAC. However, when I connect to my device (Max Pro M2), I can only use SBC. even though in the bluetooth settings for the headphones, the option HD Audio: AAC (No LDAC) is enabled.
I went to the developer options to set the Bluetooth codec to LDAC (Qualcomm aptX Adaptive Audio), but the setting does not stick.
I don't have the 'Connect to two devices simultaneously' option enabled and the priority is on Sound Quality instead of Connection Quality.
I have tried resetting the WiFi and bluetooth settings but still can't get it to work.
I tried connecting the headphones to the Sony XZs and it instantly gave the option to use LDAC and used it. This makes me wonder if this phone even supports LDAC, even though on the internet it says that it does. I can't even use AAC, I am stuck on SBC.
Does anyone have any idea? Please?

I'm on Havoc 3.11, I don't know about stock ROM.
Yeah, couldn't get it to work on the stock ROM. Now, I'm on Resurrection Remix and it works!

Does M3 support LDAC?

in Developer settings you can choose LDAC and Aptx HD, but when you connect headphones they only use Aptx. why? Software problem?
Or the headphones only can work on aptx.

How is your Bluetooth range? I recently just tried it on my Bt speaker/headphones and the range is bad. If I put it in my pocket or cover my phone with my hand, the music gets choppy right away even if I'm right next to the headphones. Also, I can't even get my bt smart lock to work with it, it just doesn't connect.
try with another player? like poweramp ?
