[Q] AptX - GPe

Please bear with me.
**When a device has AptX, on Bluetooth connection, the Bluetooth volume is automatically set to Maximum. I sort of know this because all my AptX devices do this.
I know the hTC One had AptX on its original firmware (and did the above**). I updated to Android 4.3 and subsequently converted to rooted GPe (now with a custom kernel ([Kernel][Jan29][Sense4.4.2&JB/GPe]teaMSeven2.3.6[Flick2Wake|TapWake|BLN|Hotplug|OC|Pano360] by tbalden)
From what I seem to remember Android 4.3 did not seem to have AptX (above**). I contacted hTC and they seem to suggest it had AptX compatibilty and suggested I wipe the cache (but converted to GPe before I could try that.
My current set up (Rooted GPe with tbalden's Kernel) does not seem to do the above** and my understanding is it does not have AptX
My question is does the official GPe has AptX support and is there at to check?

check logcat for apt-x or Bluetooth entries when you connect aptx enabled Bluetooth headsets. use catlog for easier filtering. you'll either get sbc or aptx mode..

Is APT-X Working or Not?

Hey guys,
I'm running freedom os and recently got a pair of mdr-1000x's. The headphones support aptx and aptx-hd, as does the ROM. Is there a way to determine what codec is in use over bluetooth? Everything sounds amazing, just wanting to make sure I get the best bang for buck.

It's working for me. I have the LG-HBS-780 BT neckband set and was able to tell it works by trying it on 2 different devices. My Moto X Pure doesn't have AptX enabled but FreedomOS 2.9 does. The sound difference was incredible!! I don't have ARISE / Viper4Android installed, decided it wasn't needed.

also for me with m1bt philips
lastest beta 8 from oxygenos
developper option, network, lastest choice is support hd aptx/aptx, check if enabled
regards

Yep there is noticeable difference! (Changed from Open Beta 8 to 4.1.5)

I'm assuming this toggle is available only on Beta 8? I'm on 4.1.5 Freedom OS and I'm not seeing it under dev->network.

My own MDR-1000x work fine in beta8 BUT when WiFi is also active might sometimes have lost packets (and sound cracks), that gets fixed if I disable WiFi.
Quality is definitely better than on default SBC but is still clearly inferior to a wired connection (as long as you are using a good FLAC as a source). So I am waiting for AndroidO and LDAC (which 1000x does support :good: )

If you're on an open beta > 8, or a Freedom CE build based on a >OB8 build it should be working. Stable Freedom is just based on the stable OOS builds and it does not work. I found a magisc module that added the drivers, but I wasn't convinced it worked right so I gave up on it.
If you use a catlog reader you can search for codec while you're playing audio through blutooth, it should say aptx or SBC. If it says SBC then aptx is not working.

Was able to look at the logs and see SBC. I'll look at the magisk module. Thanks for the heads up.

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,

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 !

Oh great! Now I am on MIUI 10 MiRoom 9.3.14 custom rom. Can we apply 10.2.3.0’s bluetooth codecs to my rom? I do not want to switch my rom but if It is the only solution I will switch

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

Question Use LDAC and Dual Audio

Hey there,
so I've ordered the Sony WH-1000xm4 and Linkbuds S, both with LDAC, but no aptX support.
To not be trapped in bad functioning SBC/AAC I want to activate LDAC to listen to my .flacs and co.
Heard I have to go for customROM to do so, as I do have Android 12, but Xiaomi does not support LDAC.
Also, Dual Sound, which means I can play one song on those two headphones simultaneously from one device
is supported by Samsung software wise, which means a customROM should also be able to do so I guess.
Xiaomi launched something similar a year back, but just for 1-2 flagships and you can connect at the same time,
but not play music at the same time with the headphones. (Both of mine have multipoint btw.)
Do you know of a customROM that matches both wishes?
Thaaanks

+1, after a long research i have no solution ford Dual Sound or dual Audio. Any mods or custom ROM to do that?
