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
Regards.

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 Guys,
I have a headset with qualcomm's qcc5124 chipset, which supports multiple aptx codecs.
But whatever i try in developer mode to change the codec as soon as i leave the menu it changes to default. I also noticed in my phone i only have aptx and aptx hd. I am missing codecs like aptx LL and aptx adaptive.
I have searched the internet and found similar threads but not a solution that works for me.

I think the 7 Pro can't use aptx LL and adaptive, thats why you can't enable it.

If the manufacturer of the headphone says that it supports aptX then by default it will be switched to it when connected.Manually changing them will reset after you exit settings.
Hi Guys, Any solution to enable the audio for galaxy buds?
i tried developer options like disable miui optimisation but it does not work.
Try doing a network reset.
Clear system cache.
I fixed it. It chose the SBC codec by default.. you have to turn on the bluetooth AAC in the bluetooth setting for the pairing

They should work with the SBC codec. Depending what the source is on my 10+ it will either use the SBC or SSC codec when set to default.
So there's still an issue... that's strange.
If you had a Samsung device you could use their SSC codec which has superior resolution.
Does P11 and P11 PRO support a variety of Bluetooth codecs?
I tested it. It is only connected to SBC & LDAC. The devices I tested were three Sony XF-1000XM3 & WH-100XM4 & Bose qc Earbuds.
All SBC and LDAC are connected only.(I don't think they support AAC and APT-X)
LDAC is Sony's proprietary codec so if you connect those that's what will get chosen by default. In fact others have tried on a Pixel 4 to get other codecs selected by Sony headphones to no avail.

I use my WH-1000 XM4 and Pixel 3A in dual device mode and it now selects AAC by default with my phone, when I first got the headphones I'm sure I read in documents that dual device mode was limited to SBC (ie disables LDAC) but maybe a FW update improved things.
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.
