Hi there,
is there any way to use LDAC or aptX HD on the device with the Stock ROM?
I've checked the Android system files and the libldac is definetly there, just not usable. Only SBC and aptX work.
Is there a chance that LDAC/aptX HD will work with the coming update to Android 11?
Thanks for any suggestions.

Hello.
Sorry for my **** english at first!
for 3 years i had a galaxy s6 edge. Now i have a honor 10, with the newest updates.
I was in the developer settings
there is only sbc, aac, aptx, aptx HD and HWA
when i try "use system settings standard" or " optional codec" doesnt work either
I only get aptx hd. I also tryed all the other bluetooth settings under the codec settings.
It only shows aptx hd on the sony app and in bluetooth connections..
Why pls help, its one of the reasons why i bought the honor 10..
hi, i have haylou gt1 earphone and when connected to poco f1 it only works in sbs codec, if i try with other devices it always connects with aac, i have tried changing the codec in developer setting but it never sticks, can someone please suggest a solution... btw im on stock miui 10.3.7.0 and would prefer not to flash custom rom just to fix this.
I know there is a magisk module that forces the SBC codec to use high bit-rates.
Other than that, bear in mind that developers settings will apply changes only when a Bluetooth device is connected.
Hello guys, I have done small research.
Our s5e device is based off Snapdragon 670 which is part of multiple interesting devices like Pixel phones. Qualcomm CPUs are including support for other codecs (aside of classic SBC) since few years back, however, to get them working out of the box the device manufacturer have to pay license fees. Since s5e is low cost niche device, Samsung didn't bother to do so, however device is completely capable to support it on hardware level. Essentially, we only need few libraries installed, and if you have necessary root permissions, its possible with classic magisk module.
Such magisk module can be found here:

I have validated it on LineageOS 17.1 via Bluetooth logcat and it does report AptX HD when connected to AptX HD supported headphones
Regular AptX also possible? I have a normal AptX BT Speaker, thanks!

Simplest way to confirm on LOS 17.1 is to flash module, open Bluetooth settings of device that you paired to. It should say what codec it will use.
Hello,
Looking for roms or kernels supporting LDAC bluetooth codec. Tried so far:
- Stock - no support at all
- Syberia A11 4.9 - LDAC on the list, but can't choose it after connecting Sony headphones which supports LDAC
- Pixel Experience Plus A11 - LDAC on the list, but can't choose it after connecting Sony headphones which supports LDAC
- Pixel Experience A12 - LDAC works fine, yay!
I will give a try PE A12, but looking for lighter and stable ROM with LDAC support.
Option greyed out on Unofficial Lineage 18.1.

It is greyed out befor you are connected with device that supports LDAC. At least it is on 3 Roms I posted by default. Did you check it with that device?
No, I don't have a LDAC device
Does Redmi Note 9 Pro (Indian) 'Curtana' support LDAC codec and APTX ADAPTIVE for Bluetooth audio streaming?
Please let me know, I'll be buying TWS earbuds based on this. Thanks!
Interesting question... I am searching for a pair of TWS earbuds (aptX-Adaptive or LDAC) and I found some info about the Xiaomi Redmi Note 9 Pro:
- the Snapdragon 720G is compatible with the aptx-Adaptive codec, as mentioned on the Qualcomm official website here with the Bluetooth version 5.1 and Qualcomm Aqstic™ audio codec up to Qualcomm® WCD9385
- aptX-Adaptive should include aptX-Low Latency and it should have retro-compatibility with aptX and aptX-HD devices as stated here on the Qualcomm website
- LDAC too is supported from what i know from Android Oreo 8.0
Searching online I found this thread on reddit about the 9 Pro (Joyeuse) where the logcat of this user running the official EU MIUI of two years ago (MIUI 11?) shows the inizializiation of some codecs, including the aptX-Adaptive.
Since the chipset is the same for both 9 Pro Joyeuse and Curtana (Qualcomm SM7125 Snapdragon 720G 8nm) we can assume the atX-Adaptive codec is supported by both phones.
Now, about the revision of the aptX-Adaptive codec available on the 9 Pro - regarding the sound quality provided by this codec - I did not found something useful for this phone, but only a thread on reddit about the dependancy of the audio quality from the revision of the aptX-Adaptive codec here .
Having a compatible device (earbuds or headphones) it is possible to select the available codec from the phone itself: Settings > Developer Options > Bluetooth Audio Codec and the codecs that aren't supported by the Bluetooth device should be grayed out (reference).
About LDAC it should be compatible without any problem I think - if the connected device support this codec - maybe it is only necessary to be selected in the phone Settings.
I am running Lineage OS 19.1 and the V13.0.5.0.SJZEUXM Firmware (Joyeuse - EU), I have no earbuds with LDAC or aptX-Adaptive to test at the moment, but I think the Redmi Note 9 Pro both Jouyeuse and Curtana should be compatible without any problem with LDAC and aptX-Adaptive. If any user with compatible hardware can do a test anyway, it would be appreciated.
