Bluetooth codec issue - Xiaomi Poco F1 Questions & Answers

hi, i have haylou gt1 earphone and when connected to poco f1 it only works in sbs codec, if i try with other devices it always connects with aac, i have tried changing the codec in developer setting but it never sticks, can someone please suggest a solution... btw im on stock miui 10.3.7.0 and would prefer not to flash custom rom just to fix this.

I know there is a magisk module that forces the SBC codec to use high bit-rates.
Other than that, bear in mind that developers settings will apply changes only when a Bluetooth device is connected.

Bluetooth stability issues?

Hi folks,
I bought a Honor 8X last week, and until now I'm very satisfied, except for one thing: Bluetooth stability.
I use Bluetooth earbuds and speakers on a daily basis, and on all 3 devices I use, I'm encountering regular drops and stutters during audio playback.
I'm using the same devices with my previous phone, a OnePlus 3T, and I didn't get those issues (well, not BT related issues, I had other ones with that phone )
I'm also regularly having troubles to connect to my Anker speaker.
Anyone else is having this issue?
I use BT headset most evenings watching TV etc no pertic brand just cheap ones and not noticed any issue also had my 8x a week nearly

I am facing same issue. Device paired but media audio and input device are disabled. Only showing device is paired
I don't have this issue, it's probably because of the software. If it's not solved with an update, then who knows what's causing the issue.

I don't have this problem. It may be related to your bluetooth device. What is the bluetooth device you use?:○

Well, he said that the bleutooth device worked perfectly with OP 3T, my guess is that the current software of the 8X is the issue.
I fixed this by changing the bluetooth codec used in the developer settings.
1. Enable developer settings
2. Change the Bluetooth audio codec to SBC from aptX to SBC

When I go to developer options, bt audio codec options are grayed out. Can't change anything...
honor 8x cannot find or detect sony wi c300 bluetooth headset...although honor is very good when using it...i am very satisfied but i only regret in terms of connecting bluetooth headset.
I have no issues with bluetooth, the range is better than my previous huawei P8 max and it doesn't randomly disconnect.
What case are you using? Metal bumpers may look cool but they kill bluetooth and cellullar signal.

Hi
I have the same problem and I'm happy to know I am not alone, on French websites I have not found this topic. So my bluetooth headsets are a model called Fozento, Version Bluetooth: V4.2.
And my speakers are Ultimate Ears Boom.
With both I have the same problem and that is very very annoying.
i have the same issue with my bluetooth devices (Bose, JBL)
Hi! I´ve got a weird Bluetooth problem, i hope someone could help. I´ts about data transfer. I tried to send some photos to my work PC from my new 8X. Did not work, it sends a few percent of the photo and then I get an error message "BluetoothStackserver crashed" or something like that. New, up to date PC with the newest drivers, Win 8.1 64 bit. Well, I tried with different other devices, Galaxy S9plus, Honor 7x, Note 10.1 2014, and even my old Surface Pro (also with 8.1 64 bit) it works with everything but my PC. (And my PC works also with all of them). I brought it home, added to my wife´s PC (older but high spec laptop) and also doesn´t work but this time without error messages. I tried to connect to her phone (some LG) also works perfectly. Sending, receiving. I literally tried everything, newest drivers, reboot, but nothing seems working. Any ideas? Thanks in advance!

Same issue with mine. APTX stutters and is unusable. When I pair headphones that use APTX, I have to turn off APTX and revert to SBC to enjoy listening to music (which is an inferior codec). Something wrong with the software and APTX codec. Hope Honor fixes this in next update.
I am facing the exact problem with honor 8x. Usibg avantree tws 120 and Changing to sbc seems to disable the issue temporarily till i reconnect the buds and forget to revert to sbc as it automatically sets beack to aptx. Worth mentioning i have another galaxy phone which doesn't manifest the problem.

Bluetooth audio codec disabled

I'm trying to change Bluetooth audio settings on developer options, but they're all disables.
Anyone knows what happens or how to enable them?
Screenshot attached.
I think you have to be connected to one audio device to get those settings accessible, they're greyed out for me as well. As I'm still waiting for my Freebuds 2 to arrive, I haven't tried myself. One reported issue with this is that those settings do revert back each time you disconnect your device, thus you have to set them every damn time you want to connect your headset.
bluetooth and audio is terribe for this device... so out of sync
You do need to be connected to a Bluetooth device for those options to be selectable but it won't let you choose options that aren't supported be the connected device.
I think since Android Oreo Android automatically selects the highest quality codec that the connected device supports which is why the option to select a default codec is no longer there.
When a device is connected you can manually select options that are supported using the developer options.
I haven't had any Bluetooth issues with my M20P. Sound quality is fine, everything connects with no problems and there are no sync issues.
If someone is experiencing issues they might want to try booting into recovery and wiping the system cache.
My M20P connected more quickly to my car Bluetooth after I did that.

I have completely the opposite. This is the only phone you can watch netflix or youtube on through bluetooth which doesn't take the video and audio out of sync.
As for the OP, you can't force a bluetooth peripheral to use a coded it doesn't support.
BOSE for example uses AAC or SBC.
Ok mine are the jaybird runs .. work fine on every other device except this.
I have a range of bt devices. Two Fiio device with LDAC, Aptx-(HD) support and a Sony wh900n with the same. When connected is automatically uses LDAC (best available quality) , but in the Bluetooth setting I can switch to aptx-hd (more stable connection)

Xiaomi Mi Box S can't pass-through HD audio formats?

From what I've been able to achieve, the Mi Box S appears unable to pass-through neither Dolby TrueHD or DTS-HD.
Dolby Digital and regular DTS work fine though.
Can anyone confirm or deny?
Thanks in advance!
yes I have the same problem
have anyone found a fix for it?

[Guide] Enabling AptX/HD support

Hello guys, I have done small research.
Our s5e device is based off Snapdragon 670 which is part of multiple interesting devices like Pixel phones. Qualcomm CPUs are including support for other codecs (aside of classic SBC) since few years back, however, to get them working out of the box the device manufacturer have to pay license fees. Since s5e is low cost niche device, Samsung didn't bother to do so, however device is completely capable to support it on hardware level. Essentially, we only need few libraries installed, and if you have necessary root permissions, its possible with classic magisk module.
Such magisk module can be found here:
https://forum.xda-developers.com/apps/magisk/module-aptx-hd-legacy-devices-armv7-t4081693
I have validated it on LineageOS 17.1 via Bluetooth logcat and it does report AptX HD when connected to AptX HD supported headphones
Regular AptX also possible? I have a normal AptX BT Speaker, thanks!

Simplest way to confirm on LOS 17.1 is to flash module, open Bluetooth settings of device that you paired to. It should say what codec it will use.

Roms/Kernels with LDAC bluetooth codec support

Hello,
Looking for roms or kernels supporting LDAC bluetooth codec. Tried so far:
- Stock - no support at all
- Syberia A11 4.9 - LDAC on the list, but can't choose it after connecting Sony headphones which supports LDAC
- Pixel Experience Plus A11 - LDAC on the list, but can't choose it after connecting Sony headphones which supports LDAC
- Pixel Experience A12 - LDAC works fine, yay!
I will give a try PE A12, but looking for lighter and stable ROM with LDAC support.

It is greyed out befor you are connected with device that supports LDAC. At least it is on 3 Roms I posted by default. Did you check it with that device?
No, I don't have a LDAC device
