Oreo and LDAC support

Hi guys,
I have a question concering LDAC on OOS 5.0 or other custom roms.
I just bought me some 1000xm2 Headphones and thought i can just update my Phone to Oreo and will be able to get some high quality bluetooth music. But it looks like LDAC isnt working. Someone mentioned libaries are missing. U can choose it on the bt audio settings but it wont work.
So is there a workaround for this problem or any custom rom that supports LDAC?
Thx in advance

Hi,
Apparently LDAC codec in OP3T Oreo ROM is working, just it displays wrong information on developer settings
Just now I try my luck to find 1000XM2 but instead of that i found 1ABT, since that one is also LDAC capable so I tried that
Guess what, the Bluetooth codec show in developer settings is show wrong
aptx and aptxHD doesn't included inside the ROM, but LDAC does loaded (see the logcat I captured at attachment, first one is aptx and aptxHD can't load due to lib missing, second one is LDAC is indeed working properly)
But still I do hope that xda would bring this issue up since this is the serious matter that Qualcomm did put OnePlus 3 and 3T on aptx codec enabled device, but then they didn't implement due to "cause prohlem"? This sounds weird for me

Ok, thx for your answer, will try it 2morrow.
Cheers,

aptx HD

Hi, I understand the P20 Pro hardware supports aptx and aptx HD butdoes this work out of the box or does a codec need to be installed? I can see it in the Bluetooth section of the developer options but I can't select anything but SBC.
Thanks

Do you have compatible head phones?

Does the option only change when connected to a compatible Bluetooth receiver? I thought my car receiver was compatible but if that's the case then I guess not.

I had the same issue with regards to Bluetooth defaulting to SBC, after some reading I discovered that it was possible to change the Bluetooth mode on my headphones by holding a button combination, it went from prefer connection to prefer sound quality and unlocked aptx and LDAC on my Sony MDR-1000X. So the P20 Pro is definitely capable of it without any additional codecs.
Maybe read the manual for your device and see if it also has something like this.

I have this problem too.
On my OnePlus One i can change the audio codec, it should not depend on the bluetooth headphones connected. My Mpow Wolverine sounds way better with the One Plus One, on the P20 pro it sounds like sh*** ;any suggestion?

I have headphones that are both SBC and AAC compatible.
Paired to my pixel, aac works great.
Paired to p20, it sutters, skips and is stuck on SBC

I noticed when there is an actual icon just after the Bluetooth device name of my headphones that says 'APT-X', in the phones Bluetooth settings.... My previous Huawei P9 didn't have it or support it so did surprise me a little as I didn't look into it when switching.

On the P20 you can change the BT codec (in developper settings) but the settings doesn't stay...

Yes, same to me.
It's a bit frustrating, seems like i have to buy another Bt headphone, also another usb c headphone.. but that is another problem

Same **** here, guys.
PowerBeats 3 are in AAC with Pixel and S9, but in SBC with my P20 Pro. And I also hate that EQ is not avaliable.
I have emailed Huawei, but those dumb idiots are asking for IMEI and system version... They don't realise, that it's a wide problem....

Contentear Huawei Team, I have purchased my P20 Pro during a first sales week at your store in Singapore. In general, I am happy with it, but, I have COMPLETELY confused with your audio experience. PROBLEM: I own two pairs of headphones: Bose QuietComfort 30 and PowerBeats 3. I don't understand why I am not able to tweak EQ over the bluetooth! S7 was able to do it, old Sony Z2 was able to do it too, but 1000$ phone by Huawei with triple camera and AI can't provide damn equalizer! I don't need any processing by Dolby, I just want to add some bass, because I am lisening to EDM, not a classical music, I don't need a analytical audio presentation. Then, codec selection is broken! PowerBeats are not able to get their native AAC, and Bose are working in SBC mode. What a shame! I can't tweak audio, and I have to listen compressed nonsense. I didn't expect that I will have to deal with such problem in the 1000$ phone. Please, release the software update, I would like to have at least eq.

Has anyone got aptx HD working? Is it much better sound quality than ACC?
Thinking of buying some Sony 1000xM2 which are aptx HD compatible but if the sound quality isn't any better, I won't waste my money

My Sony MDR100's use LDAC and sound great. They have a built in EQ profile that kicks in once they are powered on according to reviews. I could of sworn it was using APTX HD at first but I was mistaken.

Ah, I didn't know the P20 Pro supported LDAC.
Just got to wait for my Bose to sell on eBay now

Tried on a few different headphones here. Seems apt-X is working, AAC is not.
110 firmware.

My p20 pro is on order and not arrived yet, but what you should try is:
1. Clear bluetooth connection of remembered device
2. Enable Developer settings, go to settings->about phone->click on 'buid number' a bunch of times (8?? from memory)
3. Go to: Settings->developer settings->the bluetooth sections and select whatever you want to be the normal
4. Re-connect your bluetooth device. If its compatible then it will default to your previous selection.
At least, this is how it works on my S8, Zenphone 3 deluxe and Oneplus 3T, with my Sony WH-1000XM2 and audiotechnica headsetsand WI-1000X.
But they all have custom roms and i have never had a Huawei so im not 100% sure.

In theory the Bose QC 35 ii headphones support both SDC and AAC but I can't select AAC in the developer settings. Are others having the same experience?

Yeah I get the same issue with the bose headphones but ldac works when I connected to a sony speaker

Im in the process of buying some earphones that supportthe newer aptx low latency codec as I will be using them for gaming aswell. We know p20 pro supports aptx and aptx HD but does it support aptX LL

Yeah just received my Anker SoundBuds Curve headphones and it shows aptX next to the connection in the bluetooth settings. I guess AAC isn't supported as it's not listed on Huawei's tech specs page- https://consumer.huawei.com/uk/phones/m/p20-pro/tech-specs/ I also don't see aptX LL on there so I supposed that's also not supported

I've changed nothing. Only installed .128 Firmware with funky Huawei. When I connect my Ultrasone Sirius Bluetooth Headset there is automatically a aptx-Icon near the name. Nothing to change in developer-settings. See my picture on instagram:

Change Bluetooth Codec

Hello guys !
I just updated my MIUI ROM from Android 8 to Android 9. Since I have this one, my Bose QC35 II connected via Bluetooth uses the SBC Codec, which delivers a bad quality comparing to AAC. I tried to change this via the developer options, but when I set to AAC it always comes back to SBC. When I was on Android 8, I had the AAC.
Do you know how can I change that ? I'm on MIUI 10.1.1.0 Global
Thanks a lot, hope my english is understandable

I didn't find a solution, always on SBC Codec which the sound quality quite bad. If anyone has a solution

Isn't Aac a iPhone/apple thing....?
Anyways you can force a specific output mode in developers settings.
My mi8 on global beta defaults to aptx when using my Bluetooth headset.

No it isn't, it's a classical codec. I tried to force it, but it always goes back to SBC, here is my problem !

What I meant is that aptx is superior in every way.
But I guess the BT device your using is aimed at iphones and doesn't support aptx ?
Maybe try and switch to global beta and check if the issue was fixed.

Same thing on my mi mix 2s. While everything works just fine with an Nvidia shield and Android pie. So it's xiaomi fault. I'm Very disappointed because SBC is really inferior.

Try developer mode!

Already tried on dev mod, doesn't change anything. When you set on AAC, the phone simply doesn't care, hope it will be corrected in an update !

Now I am having the same problem and couldn't find any solution. In Developer options, my arrangements revert to old ones when close, they don't stick. I have Android 8 MIUI 10 Xiaomi Mi6. Via Magisk Manager, I flashed codecs and necessary modules to my phone but nothing's changed. when i connect my JBL Free to my phone, SBC logo right next to the earphone's name is there. Before I lose my mind, someone please help me! I am inexperienced to this complex Android world :crying:

I'd start by posting in the correct MI6 subforum

You can use PowerAmp, it can force better audio codec (by cable and BT).

Have you tried it ? It doesn't work

Just a quick update, since the last update 10.2.3.0, i've got the AAC when using my Bose QC-35 The sound quality is waaaaayyyy better than before. Thx Xiaomi !

I didn't receive BT fix with my new update and I dont believe I will I bought Sennheiser Momentum True Wireless Earbuds and I rarely have stutters thanks to aptX but if codecs were good I would have perfect connection with these earbuds.

I'm afraid you just have to turn on BT in order to change BT CODEC

bluetooth codec not staying

US at&t 9.0, unkodified. I can select bluetooth audio settings in developer mode butnthey revert back to default upon disconnection. Any way to make permanent?

Not yet it seems as others have reported the same issue

This is my default Bluetooth Codec on ATT official Pie update. I never checked this on 8.1, does anyone know what it was set to on 8.1 and is this what you guys are talking about?

Here is my snapdragon SM-N960W stock Bluetooth settings on Oreo v8.1.0
Mine revert back to this any time I try changing them. Only one that sticks is Bluetooth AVRCP I can run it from 1.4 up to 1.6. The rest always revert to the same as yours. See my stock note 9 screenshot.

Bluetooth Codec only sticks if an bluetooth audio device is connected and if this device also supports the selected codec. Else the codec always reverts back to sbc.
When I connect my bluetooth headphones for example it switches automatically from sbc to abtx, as this was the codec I last used with this device. Same with other devices and codecs.

note 9 with Sony WH1000 XM3
Just found that if you go to the Sony app:
Sound quality mode = Priority on sound mode
Then go back to developer options the bluetooth audio codec jumps to aptx and stays there.
Not as good as LDAC but better than SBC.

Bluetooth codecs

Hello. I'm looking for new-ish phone that supports best BT codecs for my headphones . I can't seem to find info if Note 9 suports LDAC and Aptx HD

do you know how can we check that?
if you know, I can check that and tell you.

Probably you are right.
You need to connect the desired headphone and then check if the option is avaiable.

Im on android 11, All codecs show up in it. The ones which are not supported are greyed out.
I connected Airpods, they support AAC and SBC. If Redmi note 9 supported AAC , it would not be greyed out. Same is for others, tho my headsets do not support the other codecs, they are greyed out because they aren't supported by the device.

Hmm that's shame ,guess I'll need Pro version. That website is not always right btw - it says my Honor Play has LDAC which it doesn't. And why it only shows phones from 2018 and back with LDAC selected ?
