Hi, Can i use LDAC codec with s22 ultra and Sony WF-1000XM4 ? In the developer options i can't, even if I select LDAC, it remains on AAC ? Any ideeas please ? Thanks a lot
You don't need to go to developer options. Open Bluetooth settings, find the XM4, tap the settings wheel and select LDAC codec (you need to have the headphones connected to activate this option)
That stumped me as well when I first tried activating LDAC as well on my Soundcore Liberty 3 earbuds. xsam123 is correct
Perfect, it works ! Thanks !
Hi!
If you have any other problems with LDAC, even with using developper option, don't waste you time any further.
(I've spent so much time to correct the issue in this way)
Developer solution's won't work.
And you'll not have the choice to enable LDAC in Bluetooth normal user setting
Reboot your Xiaomi with hard reset.
Everything will become clear and operational.
LDAC Choice will appear correctly again.
Best regards
Be sure HD audio is enabled as LDAC codec in the bluetooth device info, in the bluetooth connection app.

Hi all!
I wanted to open up a discussion about the new Oreo features for Bluetooth codecs in the developer section. I haven't been able to find a comprehensive guide or info anywhere that covers how it actually should work, and I don't believe it's working correctly - I would like to explore more with you.
I'm on a Google (carrier free) Pixel, using a fresh install of OPR6.170623.012 - which is working brilliantly by the way.
It seems to me that I can't make the settings stick, if I for example change the Bluetooth Audio Codec to aptX, or modify any of the other settings when I go back in it always reverts to the 'Use System Selection (Default)' option. I'm typically trying this with Bluetooth off, changing the setting and turning Bluetooth on. I've also tried rebooting in-between, as well as different variations. The developer toggle is set to on of course.
It may be my misunderstanding of how this works, but it even if I stay on the developers screen and change the codec, if I turn Bluetooth on and it connects to a device, for instance my in-car Bluetooth audio, which I believe supports aptX, it doesn't care what the codec setting is and displays 'Streaming: SBC', which is of course what I'd expect would be overridden.
The only thing that seems to stick is the AVRCP version. I'm wondering if the Bluetooth HCI snoop log will provide any information?
Have any of you had any experience with this, or have anything to add to the conversation?
Many thanks in advance,
OK so it seems this codec list doesn't allow you to set a 'default', it just allows for modifying the codec during playback?
What I've experienced so far is that it does work with 'Use System Selection' to use the best codec available on the device you are connected to. It also allows you to change the codec to another while streaming/playing. The sub-text under Bluetooth Audio Codec does dynamically change from SBC to AAC.
Example: My headphones support SBC and AAC, the Pixel defaults to AAC on establishing a Bluetooth connection but does allow downgrading to SBC by picking from the list (as a test).
It however doesn't retain whatever you pick in the list if bluetooth is turned off then back on, it basically always defaults to system selection, then auto-picks on every connection. Perhaps this is by design, it is developer tools after all.
I haven't been able to get this to work with aptX in my car yet with my Pixel, even though it is apparently supported?
Also of note: To achieve AAC on my Bluetooth headphones I had to put them into a 'Priority on sound quality' mode and also turn off the Bluetooth phone (i.e. call connectivity, music ONLY) on the Pixel connection to achieve AAC.
are you sure that your car supports aptx? before this developer option it was very hard to actually see the codec being used.
I believe so, the Bluetooth product states that it supports EDR and aptX, but yes, I cannot be 100% certain.
Are you suggesting it should be possible with Pixel and the Oreo build as-is?
What is AptX?
Click here to find out
I noticed that the custom bluetooth codecs( like the aptX, aptX HD, LDAC, etc.) are not working even if we have devices that support it( like earphones, headphones, soundbars, etc.) For example, I own a Samsung Level U wireless headset, which is compatible of aptX codec, but whenever I connect it with my Mi A1, the codec in Developer options switches itself to SBC.
So, I found a workaround for it on OnePlus 3/3T Device Forum. @theduke7 has created a Magisk module which enables aptX/ aptX HD on One Plus 3. I flashed that module, and Voila! The codecs started working on my phone.
How will this help you?
AptX increases the quality of audio transmitting over bluetooth considerably. So you will be able to hear nearly lossless, CD quality audio from your device.
Just flash the below given Magisk module in Magisk 14.0+ and reboot.
For those who can't find the option,
Go to Settings >> System >> Developer Options >> Bluetooth Audio Codec

Just thank @theduke7
Before posting, please check whether your wireless bluetooth device supports any of the above mentioned codecs.

Doesn't works for me...
Codec stills revert to SBC every time I connect my BT headset.
It's a Driftin DBE-301BGY. But I don't know if it's apt-X or apt-X HD compatibe.
No matter wich codec I choose, always revert to SBC....

Your wireless earphones are not aptX/aptX HD compatible, mate. I googled them just now.
Also, the module is sometimes unstable. It reverts back to SBC even when we choose aptX or aptX HD. A simple reboot should solve that problem. After rebooting, before connecting the wireless, go to developer options and manually select the supported codec, and then connect.

Dude, I'm not a developer. I just found out that this module works for our device, and so I posted it here, giving necessary credits.
And I don't get any noise in my earphones. Can you try a fastboot rom flash without wiping data?
Does it work on custom ROM?
On Oreo 8.0 all works fine, aptx and aptx HD.
At Oreo 8.1 (July Update) - only aptx is working. U can select aptx HD in the Developer/Audio settings, but dos not have any effect.
Any suggestions?
it only works if the xiaomi was rooted. Without root the APT doesn't work even more if you installed the drivers and modified the build.prop
What do U mean? Pls explain.
Magisk 16 Up and running....
Think ist's a 8.1 Bug, HD get -1 priority

I did it manually and I added into the build.prop located in system:
persist.bt.enableAptXHD=true
persist.service.btui.use_aptx=1
persistent.bt.a2dp_offload_cap=sbc-aptx-aptXHD

This way you have to flash stock system.img before ota will work again. Just to keep in mind.
Does this work for Pie? I recently updated my MiA1 to Pie a few nights ago.
I'm trying to use this on my Sennheiser 4.5BTNC headset.
can anyone confirm whether it's working on latest Pie STOCK rom for mia1 or not? I want to install this, can anyone confirm & help me?
Xiaomi mi A1..aptx or ldac on Pie
Anyone got a guide for getting aptx or ldac working on Pie...
Hi.
I've seen barely any mention of this issue.
I've tried several ROMs like Bliss, Havoc and Evolution, all of them Q.
I have an EarStudio E100 DAC which supports AptX and AptX HD, which were working perfectly well on Android 9.
I was able to select the right codec from Developer Options and the sound would be much better and SBC or AAC, but now on Android 10, there is no difference whatsoever. I can select AptX HD it does not stick and reverts back to the lowest quality codec.
Any idea on how to solve this?
EDIT:
On Reddit, from user CoolGeek71, I found out that selecting the capabilities FIRST and only after that selecting AptX HD inside Developer Options, Android will use the requested codec. So, instead of selecting AptX HD only as it was on Pie, I have to select before the "Bluetooth Audio Sample Rate" to 44.1kHz or 48kHz and "Bluetooth Audio Bits per Sample" to 24 bits. Only then, stupid Android 10 will use it.
Once again, Google making simple things harder to use.
I noticed that if I change the developer settings for Bluetooth codec it automatically changes it back to defaults after I close out of the settings.

This stupid problem is also present with LDAC quality settings as well. I use the Fiio BTR5.
Interestingly, Beta 8 fixed this issue. However this bug has reared its ugly head on the newest 1.0.3.1 again.
I was thinking of buying this phone, until I realized it "presumably" doesn't support the LDAC audio codec [Info from bluetoothcheck.com]. I want to know from an actual user, is this true? Because, I saw on YouTube, that for someone else it actually did work.
Any answers will be appreciated!
Why would you buy this phone to use with wireless earphones?

Well, mostly I would use the headphone jack, but, occasionally, at the gym or while running, it's more convenient to use bluetooth earbuds (And, I don't mean some kind of a mid tier ones, I would be using 1MORE ANC Pro EHD9001BA)

I can confirm LDAC works with my Sony 1000XM3 headphones on both the V50 and G8.

I have also tried the the DTS:X feature on my LG V35, but for me, particularly, on wide instrumental or detailed (heavy metal, etc.) genre songs, it interferes too much with the sound equalization. Therefore, I like to keep it flat and original, but I understand the appeal/it's a personal preference.:good:

The Side to Side option works best for me. I listen to all kinds of stuff, also make some of own ?
Information for people who have LDAC headphones and cannot turn on this mode, and in Developer Options they have "Bluetooth Audio LDAC Codec: Playback Quality" greyed out
Applies to Android 11
You have to go to Settings-> Connected devices-> Bluetooth-> select the device - enter its settings (gear on the right) -> Connection type and change from Most stable on Best sound quality.
From now on, if the device supports - you can choose LDAC or AptX HD, which are inactive by default, because the phone pairs devices by default in "Most stable" mode.
I fought my Sony WH-1000XM3 an hour before I found it out ...

Hello, I have the same problem on another device. For some reason, the "connection type" option accessed by clicking the gear isn't available on all devices.
I managed to make it show up on the WH-1000XM3, but I don't know how, and know that I'm using another similar device (Fiio UTWS5 for the curious), I'm stumped as to HOW access this option.
I did however, successfully forced aptX (not HD though) codec through developer options, but that's it.
May you help a noob?
Thanks!
Strange Question.
OFC yes!
Any way to enable all of the bt codecs that are supported by the processor but disabled by samsung?
Can only select SBC.
Bt device needs to support the codec.
Some apps use only sbc.
If the app and device use the blanked out codec try clearing system cache, a network reset, turning Developer options off then back on.
Make sure you didn't disable a needed service, turn off global power management.
The problem is Samsung disabled the high res codecs. Even with a supported device, it can not be selected.
LDAC and SCC should be available.
No APTX HD.
I got ldac working. Thanks

"When you connect a bluetooth device, this will automatically switch"
Welcome to XDA
English only please per forum rules.
Best to check it in Developer options when connected and using to verify the codec in use if set to automatic detection.
Samsung also hides a toggle in Settings - Connections - Bluetooth - your Bluetooth device. This is how I got LDAC working on my Soundcore Liberty 3 headphones.
