Bluetooth LDAC or aptX codecs not working on 9.6.7.0 - Xiaomi Mi Max 3 Questions & Answers

With the global version 9.6.7.0 (OEDMIFD) neither LDAC or aptX are working. Even when trying to enable them in developer options.
I'm using it with my shanling m0 DAP which shows the codec being used. With my other phone running Android 8, LDAC is activated. Here only AAC works.
It also works on my friends Pocophoe running MIUI 10.
Anybody got it running or will I have to wait until MIUI 10 is out?

Hi, did you managed to solve this problem? Have you tried updating to latest V10.0.1.0.OEDMIFH to see if that fixed the problem?

Yes, I updated last week and LDAC is working perfectly fine now. Thanks for asking

Bluetooth audio codec support?

Hello, can anyone who bought Moto Z Play confirm it supports aptX audio codec and successfully play audio through an aptX connection to an aptX supported audio device, or confirm it does not? On the official pages and GSMArena specs I saw only A2DP which is SBC codec.
I wrote to Lenovo tech support and they responded they don't know anything about aptX then suggested me ask aptX team. So wrote another e-mail and seems that the response will be slow. So does anyone can kindly prove it here? Thanks you.
There is another way to confirm, one can check if there is a file named something like libbt-aptX-ARM-4.2.2.so under the path /system/lib/ which means this device supports aptX codec. Can somebody confirm this?

There is a file with the exactly name you said on that folder. So i am inclined to think it has support to aptX codec.
Even the first Moto G supported aptX, last years Moto X Play supported aptX, even though Motorola did not mention it anywhere. Somehow they never talk about aptX but one can take it as granted.
Weird how aptx support almost never seems to be marketed or even mentioned. It costs money to license, you'd think hardware makers would at least tuck the info somewhere. Not that I'm implying that this phone absolutely does support it, as much as circumstantial evidence would suggest. Only way to be sure would have someone with one of those devices that light up some indicator when it's supported test it and chime in.
I'm using Moto Z transmitting to Cambridge BT100, and the LED on the Bluetooth dongle blinks every 2 seconds. That means apt-x is ON!

Does Mi Mix 2 supoort Aptx HD Bluetooth Audio

Anyone know if Aptx HD supported by the device out of box or not
Im intersting more for the global rom,not the chinese one.
Thanks.
I tried Aptx HD connection of WI-1000X with Global ROM(MIUI8 V8.5.1.0) and Chinese ROM(MIUI9 7.10.12).
As a result, although connection could be made, sound cutout always occurred.
There was no problem with SBC Codec connection.

Huawei Freebuds on Oneplus 5T

Recently I bought Huawei Freebuds and it works quite well.
However, 5T can't connect with freebuds by AAC codec even though freebuds supports AAC codec and other bluetooth 4
.2 devices works through AAC very well.
Is there anyone who have connected Freebuds with 5T through AAC codec?
Alredy asked to Oneplus bughunters and submitted my bluetooth logs, but haven't received any replies for a while.
Hey! Same problem here. Shame they don't support AptX... The video lag is horrible...
Same here.
Many problems (1s decal, some bad connexion ...)

Glad that it's problem for everyone, just not for mine. Thought mine is defective.
I sent bluetooth log to Oneplus dev team and it was submitted to JIRA. Hope there would be an relevant fix on future OOS or firmware update for Freebuds from Huawei.

Apt-x support

I can see it in developer settings but does this phone officially support apt-x? My Bluetooth earphones have apt-x as they work with my p20. Thanks all
I got it to work by flashing the apt-x enable magisk mod for OnePlus found here
