Hi,
I've the OP5 128 GB, in the setting and advanced, we have an option Bluetooth audio codec. In this step we have 3 codec we can try :
* aptX HD
*aptX
*SBC
By default, SBC is select, but do you have try others ? what's the best ?
Sometime, i loose the bluetooth connection in my car and i must to off/on the connection.
Thank you.

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..

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?

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
Anybody know how to enable Qualcomm aptX to work with Bluetooth headphones?
snapdragon 430 does not support aptx codex, even you have aptx library.
maximum codec for bluetooth is aac codec, you need enable this in bluetooth device setting > HD Audio.
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!
