Dear users who already decided to try Oreo roms, have you seen any settings related to Bluetooth codecs? Any signs of aptx or LDAC codecs?
Yes, seen but not tried.

Thank you. Can you report later if it's working or not?
LDAC works

Don't know sure about aptX as i didn't feel the difference in quality, but i can confirm that LDAC is working on Nitrogen OS (in pretty much all versions since it came out with Oreo). I am using the Sony MDR 1000X and it uses LDAC by default now, after oreo update. You can also manually change the codec from Bluetooth settings (turn LDAC on off for that audio device) or through developer settings, where you can choose the codec and even the bitrate, sampling rate etc etc. And it changes on the fly, so you can really feel the difference. LDAC is well worth it. But I've seen that on the highest quality, you need to be close to your device, else the sound can drop out sometimes.

Thanks for making effort and clearing things up.
LDAC is working perfectly on my OP3T with OS Beta 16.
Viper4android doesnt work though when headphones are connected with LDAC. I am using MDR-100ABN. Thye have LDAC and OP3T is streaming perfectly on that codec.
When I use my Jaybird X2s, codec switches to SBC automatically. Viper4android works on my X2s. I am not seeing AptX option in developer settings.

greetings. Does the mediapad m5 support aptx or other high quality bluetooth codecs? Thanks!
"It does..." Well it's listed in the developer settings, however each time I enable one of them it reverts back to the default one... Maybe I am doing something wrong, but I could not get it working.
Also, keep in mind that wifi and Bluetooth don't work well together.
Yes it does, I like the sound from my m5 more than from s9, when it comes to Bluetooth performance. I played with s9 settings but couldn't come to the sound m5 gives via Bluetooth. Don't even know why they are sound so different.
Aptx and aptx HD are listed in the developers option. But I have no compatible devices to test it. I have a Sony AVR that has LDAC but it appears the M5 doesn't have LDAC codec integrated, even though it should be baked in Android Oreo.
thanks for your answers!
I have read the the device is support LDAC Bluetooth.
But when I change Bluetooth codec in developer setting to LDAC it got no sound. Testing with my fiio btr3 the indicator light change to white thae mean I using LDAC but got no sound.
The only codec that work is just sbc, aac and aptx.
Anyone know how to enable LDAC or just tell me that it not supported LDAC yet.
PS. When using the other codec it has worst quality than it should tho compare to my Nokia8. Why this happen?

Bluetooth speaker/device should support also LDAC. Not only the Smartphone that have a LDAC capability

i have the same issue. I have Sony wh-1000xm3 headphones. When i switched the LDAC codec. Sound just gone. Is anyone found a solution for this?
I search for it and found the samsung s9 s8 etc. phones have similar kind of problem. They have a solution for this. They just turn off the "dual audio" feature. But i cant find that setting in A3.

Same thing, @kaelthasxx. I'm also trying to setup my wh1000xm3 with the Mi A3 and there's just no way of making ldac work. Not to mention that using aptx gets me an awful quality. If I run a frequency response test I get a lot of crackling at frequencies around 17-20khz with aptx.
The best quality I managed to get out of this setup was using sbc, which is a shame since the headphones support all the way up to ldac.
I think this is some issue with the OS (I'm using the phone's native Android One), since in theory the BT soc of this phone should support these technologies. Hope they fix it for Android 10.
I had install custom rom and it work just fine. Can't wait for official release tho

What ROM are you using? The official one doesn't even support aptx properly (I get a lot of distortion using it with Sony's WH-1000xm3). Not sure if I should flash a custom ROM or pray for a fix in Android 10.
Anyone have a solution for this, just got some Sony Bluetooth cans for xmas and bow have same issue...
Is it confirmed fixed in Android 10 (ie a month or so factory fix all going well) or should I just go custom rom and fix it now (although the whole reason I went a3 was to get a stock Android device)
If I was to go rom route what's the suggested rom? I'm assuming a3 and a3 lite use the same base rom package?
Thanks to all in advance

I can't confirm for LDAC, but AAC doesn't work, it always revert to sbc. For now is better to try a custom as bluetooth codecs never worked for me.
here you go! was also waiting for long months to access any better then SBC...
A3 with A10 stock, April version + Sony XM3, latest app version
--> AptX is on!
checked developer settings and this confirms. AptX is shown on (its not AptX HD by the way). trying to select any better eg LDAC wont stick when return from setting, also no codec effect.
at least something... good luck guys!
No

Any update on this? How does the phone do with the latest firmwares?
(I plan to get Sony headphones)
Mi A3 with Android 11 here. No LDAC option, best is aptX but the WH-1000-XM4 dont support it so... best codec is AAC.
Hey guys,
I have connected my A3 to a roidmi in my car and i have noticed there's a very poor audio quality over a blurtooth. I have also checked it with a stereo in my living room. Does anyone else got a same problem? How to get over it?

Ya i do have this problem, its a bug that hasn't been fixed yet. Turn volume down by 3 steps and you will be fine.
just enable developer options and set it to the highest quality, by default it is using the lowest bandwidth with the lowest quality
There is an even more serious bug with this phone and Bluetooth : if you get a call while streaming audio to a Bluetooth headset, music stops as expected, but then playback fails after the call has been ended. You need to reboot in most cases in order to get back music playback.
Tested with several Jabra and Plantronics headsets and different music players.

Are you sure it's actually doing this? Because when I switch Bluetooth to using another codec or higher quality, then hit back button, then go back into dev options, all the settings are back to default, so I don't think it actually does anything. I have a Bose qc 35, which is supposed to support aac.

Try this Magisk module and increase the bitrate of SBC codec. You might need to experiment a little to find the best value for your setup. Start at the max (or just use the recommended value) and gradually decrease until it's stable. High bit rate SBC can have higher quality than APT-X (HD) - you will need to disable "HD Audio" in Bluetooth device setting to force usage of SBC.
I was using it with Mi A1, but haven't tried with A3 yet.

Btw. changing BT codec in developer settings never worked for me, not sure what's the purpose of it
Same problem for me. My bluetooth headset sucks at this device. I hope we can find an easy solution immediately

Its not the bitrate, it happened with me many times before so i can tell, phone boosts the volume past max for some reason which causes distortion, reducing volume fixes the issue

I'm trying this module. I turned on Bluetooth snoop logging to see if I can see what bitrate I'm actually getting connected with. There is text .log file enough which is only few bytes and a larger binary file with
cfa extension. You don't happen to know what format this is, do you?

CFA is a binary btsnoop file containing all the packets related to BT connection. It should be possible to open it on a PC in Wireshark. I couldn't find a way to open it on Android directly.

In my case (JBL Free X), this is not an solution, it's only quite better, when i set bitrate higher than 574
I think I have found solution for this problem. I have installed miui 11 on my mi a3. Then I have installed magisk and gjf_bt module. Noises no more. For some reason this module doesn't works on stock rom

I have the same problem... after a factory reset it worked for a week ... now the problem returned ... did anyone find a solution?
Our phone was announced to be capable of aptx and aptx HD. I own two different bluetooth receivers with aptx HD enabled. But when I connect the phone to them, it uses only aptx, as the connection info on our device and the LEDs on the receivers reveal. This behaviour did not change from Android 9 to 10.
My wife has a Mi A2, and with this device aptx HD works on both devices under Android 9 and 10. Is there a hidden way to activate aptx HD on our phone? Meanwhile I think our phone is heavily neglected by Xiaomi because such features present in a Mi A2 mysteriously vanished.

It's on developer settings.
Also, if forcing aptx HD is not working or has bugs, remember to report it.
This was the first thing I tried, but predictably switching to aptx HD in developer settings has no effect (I wonder what use these settings have - I never heard that someone succeeded in activating codes this way which his phone didn't choose automatically).
Update: I changed to crdroid 6.6 - and now aptx HD works flawlessly.
Hi sir, today I've got issue with connection to Fii0 BTR3K - no sound from PowerAmp which I was using for weeks without problems before. I did security update from May yesterday (yep late a bit) and got this issue. Fortunatelly to me I have SBH50 from Sony to test everything on low profile SBC connection. Lucky to me, I did another update to August security patch for Android 10 today.
Now I have Aptx LL ([email protected]) working with BTR3K (purple indication on LED). What I learned from today: Do not touch Dev settings! By misstake Dev settings could store your input as wrong data in 'system default' for application (PowerAmp in my case) and lead to missfunction. In my case PowerAmp was reading [email protected] even from non-aptX device. Second: actual condition of connection could be changed during SW initialization. So test your player SW and try to reset it as I did.
For specified [email protected] I am using Hi-Res output of PA. I am pretty sure in numbers as I can hear the difference between SBC and aptX, and hear difference with 16 to 24 bit resolution change (by enabling\disabling tone processing in ounput pipeline). To enable 24 bit in PA you should disable \reset to default dithering method.
I think AptX-HD isn't fully supported by 2 reasons: no real benefits over LL profile + licensing catch.
Hope you will learn something from my evidence
I have haylou gt1 plus earbuds. Apart from bad connection , the buds are aptx-HD compatible, one of their selling points. When i go to developer settings to check, aptx is used. When I change it to HD, it detects the change, nothing happens, and when I go back, and enter dev settings again, it is still on aptx . I think that's time to throw it in the sea... it's already blue
Sapper Morton said:
Your earphone doesn't support AptX-HD, that's why when your manually change to it using Developer Options, the codec isn't selected; use AptX or AAC, as advertised by Haylou.

It's weird cause all reviews I read, specifically said aptx-HD, but you are right. It's only aptx. Nevermind. My mistake !

Cause I'm on miui 12 and i have lots of issues. First left and right connects to the phone at the same time and then i have volume problems
I am almost ready to pull the trigger on buying this phone but just wanted to be sure of the audio options first.
If I pair my BT headphones and go into developer options then I can set the Bluetooth codec to aptx. Does this mean that the phone supports this? I have seen reports that aptx is not available on Samsungs but this seems to contradict that.
If I have to go into dev options and enable it myself - that is fine.

In the dev settings, there are these options:
SBC (active for me)
AAC
aptX
LDAC
Scalable Codec
But I'm not sure if aptx works. I'm using SBC with the Buds+

I tried it with my Haylou GT1 Xr that supports aptX recently and it worked just fine. Looked under dev settings and aptX was showing as currently used codec. You should be fine.
