[Q] Choppy music on blue tooth headsets

I'm having a problem when streaming music over my blue tooth headset while being active (walking, running, moving about). When being still. it's fine and wired headsets are fine. I have the VZW DevEd from Moto. I have spent a lot of time in their chat and on the phone with them and in fact I lost root because they made me go back to stock and take the OTA because they don't know what it could be. So after all that, they want me to send it in for repair. I don't have another phone so that isn't possible. They really have the poorest customer / tech support of anyone I have ever dealt with (actually VZW is quite good). I really believe that this isn't a problem with my phone. I think it is a problem with all Moto X or maybe just VZW Moto X and there is no way to get Moto to check it. Anyone that can test this please give me feedback as to if works or not. I used Google Play Music and Pandora.
Edit: Choppy should have been used to describe the problem.

[Q] Moto X Bluetooth driver downgrade?

I use a Sony SBH80 Bluetooth headset that skips for one second every time I press the power button to lock the Moto X or when the screen locks out due to timeout. This issue is not present when the SBH80 is paired to my iPhone 5s. Both the Moto X and SBH80 support and use APTX, where as the 5s does not.
Sometimes, it also skips briefly when I'm on a bus and it hits a bump. Again, never happens with my 5s.
Normal troubleshooting has not revealed any solution. Turning off all radios except bluetooth has no effect, increasing Audio Buffer Size and/or Audio Thread Priority does not help and neither does disabling BT DVC (direct volume control) or DVC. Bluetooth is set to High Priority in PowerAmp.
I have tried with Google Music, PowerAmp and Neutron, all exhibit the same issue regardless of settings (which I've tweaked to hell and back in an attempt to troubleshoot this issue).
I have two Moto X 2013 on 4.4.4, one is completely stock rooted, the other is stock rooted + debloated. Stock kernel. Both exhibit the issue.
As I have two Moto X's I don't mind if my secondary gets hard bricked in trying to downgrade the Bluetooth Driver. Does anyone know how I could achieve this?
[edit] Disabling APTX by renaming /system/lib/libbt-aptX-ARM-4.2.2.so.bak results in broken Bluetooth (won't turn on). Renaming it back worked in enabling bluetooth again. Will proceed with injecting 4.2.2 bluetooth related files in to my spare Moto X once I verify if their last modified date is different.
[edit2] searching through /system, all bluetooth related files have very basic config commands that I doubt would help =( I think the actual driver is in the kernel and I'm unsure how to take it apart

All Mate 10 Pro have Crippled Bluetooth

I have noticed this is a widespread issue and I've decided to raise it. This needs to be fixed and Huawei should stop ignoring this problem. The Bluetooth is basically crippled and locked to SBC. I've tested multiple devices and all exhibited this behaviour. Why is it ignored? Are all the reviews fake?

i read that Bluetooth options in pixel dont stick too. so it must be some wierd oreo crap. you cant even change gpu renderer. it always defaults back. best way to handle that is to chat with huawei support and check it out.

I don't use Bluetooth very much but it appears to be the same for the regular Mate 10 as well. I'm currently using my virtual desktop so I could not test if after changing the setting in developer mode does it stick after a reboot?

this confusion is due to a lack of follow-through. all oreo devices have this "issue". it's not an issue at all. if a connected bluetooth device supports these codecs, the best one will automatically be selected. it is not limited to huawei devices. this is normal and does not affect functionality. you should take down this thread so no one throws any fits for no reason.

Well mine switches to aptX automatically when I connect to aptX-compatible devices. However you are correct that I cannot manually change it in developer settings.

Further testing has shown this issue not to be an issue, I've managed to successfully connect to an APTX device and the codec was selected. Video removed. Apologies for this confusion.

Doesn't matter, it will still randomly switch to loudspeaker and the quality will still be terrible.

I don't have any issues regarding Bluetooth for now, haven't really tested aptx I think, but it worked fine otherwise. And never switched to loudspeaker or so

It's not crippled, it's buggy.
SBC and aptX have high noise floor and specially on SBC, it causes some deformations to the Audio.
AAC is totally broken.

Good for you, people here all have Bluetooth problems:
https://www.android-hilfe.de/forum/...oth-problem.853624-page-19.html#post-10970173

I have no issues with my Bluetooth headphones, the Sony WH-1000NX2
The highest quality of transmission is selected automatically, LDAC, that's 990 kbit/s
It's the best Bluetooth can do in the Audio section.
The Sony headphone App confirms the LDAC connection

i am trying my friend's MDR 1000x. i tried both SBC and LDAC. Now I can't go back to LDAC. Help please

Aac not working on p20 pro, works fine on the pixel 2

Bull****.
AAC No longer works on my head unit and my Bose QC35 Headphones.
It worked perfectly before 8.0.0.128 update.
Factory Reset does not work, nothing works. It refuses to use anything else than ****ty SBC.

they are reporting issues with many devices on that forum. android has always had some issues with bluetooth. huawei is no exception. my samsung and sony devices were the best by far. i think it's because of improvements that they make to the android system.

Anyone on b142? Can you comment on if the Bluetooth audio quality is better?

Can anyone confirm if b142 solved sbc problem? I think aac is stilo broken, but sbc quality?

Solved.

I don't have a clue what you guys talking about with all those 3 and 4 letter/digit combinations of names but i feel I've gotta share i use Bluetooth all day long for different kinds of profiles and i mean all day long, and to say this doesn't fail nearly as much as nougat did would mean i imply it does fail to a certain, however small, degree, which isn't even close to being the case, so... But i do notice the in band ringing settings don't stick just like they don't stick in my Oreo S5...

I've had Android phones since 2012 and the Huawei mate 10 pro is the only one with Bluetooth issues. Constantly dropping parts of songs when connected to my mazda 6. Infuriating to say the least. The most expensive phone I've ever had....

Use 2 Bluetooth-devices at the same time?

So as far as I know the Sony Xperia XZ1 Compact is capable of Bluetooth 5.0, on other brands like Samsung with Bluetooth 5.0 you can connect 2 Bluetooth-devices at same time. As example you can listen on 2 bluetoothspeakers simultaneously. Is there any possibility to do that on Sonys Stock Software as well?
Thx in advance

Of I look on my cellphone (XPZ) there is in the Developer Option an option to change the count of BT DEVICES, but I didn't know if it's work or not

Well I tried this once before but now it worked. Now I can connect to both devices and switch audio between them and the device. So thank you:good:
Do you or anyone else know if it is possible to play audio on both aswell. In sound settings I only can switch like stated.

Meshing, connecting to multiple devices, is down to Bluetooth V5. But that doesn’t mean application developers are going to design audio streaming to multiple devices. This is pretty complicated and a bit niche, I mean why would you want to?

Audio quality drop on bluetooth

Hi everyone
Little bit lost on this and not sure if it's just me but hoping someone can help or point me somewhere. I have a s10+ UK edition. And a Samsung galaxy watch.
When I connect the phone to the car the audio is low quality and hisses a lot. When I put the watch into plane mode. Cutting it off from the phone. All is normal.
Have never seen this happen before. Any ideas?
Thanks

So you have bluetooth connected to the watch and car at the same time?
If so, my guess would be a setting in the watch for the volume of music. Or in the phone, go to settings / bluetooth / advanced / dual audio. Select it and play with the settings to setup what to do when two bluetooth audio devices are connected

Had the same problem with my cheap external bluetooth to FM adapter.
Turn on Developer Options and adjust the bluetooth profile while connected to your car audio.
Having Dolby Audio set to auto might also have an impact.

Thanks for the advice but no luck so far.
The settings under developers let me change when nothing is connected but they revert back to sbc soon as I leave the menu. And they are locked out when connected.
Also dual audio does nothing.
It only has the issue when the watch is connected.
As if its taking the bandwidth.

@ninjatiger26
@theanykey asked you to change the AVRCP version.
You can only change the audio codec from the default one (SBC) to something like aptX if your receiver supports it. And yes, you can not change the codec on the fly while playing.

Apologies for the delay, has been a mad few days!
Sadly changing the AVRCP didnt help on all versions.
It seems there maybe a weird one however on the codec. It reverts to SBC which from a bit of muddled googling is all my receiver supports. from non iPhone devices. However, it takes AAC if its a iphone.
Seems odd to me however they would limit it. Like i said this is from googling so maybe incorrect.
the stranger part is however i paired up a Oneplus 6 and the watch all was fine on SBC codec. its just watch and the s10+ it has an issue.
Admit very lost on this one.

I'm having the exact same issue. I've got an S10 Plus and a Galaxy Watch Active (both in the brazilian versions), and there is a noticeable crackling and loss of quality when I play music on my car stereo while the phone is connected both to the car and the watch. If I put the watch in airplane mode, the issue is gone.
Also, it only seems to happen with my car. I've tried to replicate the issue with my Sony WH-1000XM3 headphones and an Anker bluetooth speaker, but with those devices there is no noticeable loss of audio quality.
I've tried resetting bluetooth setting, messing with the codecs in developer options and pairing both devices again multiple times.
Anyone got any ideas?

See if the problem persists when you only share your Bluetooth audio to your vehicle and not calls, contacts, or messages.

Just tried it and still got the same issue... I've pretty much given up by now.. hoping for a future update to solve this..

Why not Google it?maybe you will get a solution for this problem.

Same issue here on my s10+. When playing any audio in my car via BT i hear the distortion/hissing noise especially when the song has a higher treble frequency.
I have just about tried all fixes i could find on Google, and no luck.
When connecting to my ear buds (Jabra Elite 65t) it disappears and checked in developer mode that it supports to AAC for BT Codecs.
But when connecting to the car it reverts to SBC.
The issue clearly lies on Samsungs side, as my brother has a Huawei p30 Pro, also has bluetooth 5 and plays amazingly well in all aspects (Bass-Mids-Treble).
I know I'm posting this almost a year later, but i am desperately looking for a fix.
SN. I have recently updated my phone to Android 10, despite all the complaints to Samsung from many users... Sadly this issue has not beeing fixed on my side.
Does any of you still have the same issue?

I have the same issue with S9(android 10 ui2)
- no dou audio diable option
- bluetooth conected only to my earphones, with no car.

I’ve been a Samsung phone user since the S5 and this issue persists across all their phones since at least that one. The only real solution is to avoid the SBC codec or turn off your watch while listening to music. It will never be patched as it’s been going on for over 6 years. In the early days Galaxy phones only really used SBC so you couldn’t avoid it.
APT-X and AAC are your best options. Good luck finding those on a car system. You can easily find headphones that support them.
