Only mono sound through Bluetooth - Moto Z2 Force Questions & Answers

I just discovered that my z2f streams only in mono through Bluetooth: the left and right channels are not separated but mixed together. I tried with several sources browser, Spotify, etc.), and at least two bt headsets with all the codecs available, including aptx, ldac.
I'm on the latest Oreo firmware.
Does anyone experiences the same?

Ok, I found it: there is an option at accessibility settings where you can switch the sound to mono, it was on.
Who and why switched it on is a mistery to me.

Android P Beta DP 4: Bluetooth Latency

Has anyone noticed any latency with Bluetooth headphones on DP4? I was on Oreo and previous DP3 and had no issues with my truly wireless headphones. Using Sol Republic Amps Air and Samsung IconX 2018 and they both now have Bluetooth latency with video, was not like that before. I tried changing the codec in dev ops, but for some reason, it keeps reverting to the same codec. Possibly an issue with the headphones not supporting every codec. But my challenge is this was not an issue before.
Looking to see if anyone is reporting similar issues or if I need to do some more internal investigation on my hardware.
Very strange that headphones that worked without latency, now have it with the latest DP. With my Bluetooth headphones and car system (which have never had latency) I haven't gained any issues with any of the DPs.

Bluetooth music bug

I have a pair of Jabra Elite Active 65t Bluetooth earbuds. I had no problem connecting them to my Huawei Mate 20 X L-29 and they auto-connect each time I put them in my ears, but I have an odd problem. When I put them in my ears they say "connected" and play a little tune and I can then receive and make phone calls, call up and use Google Assistant, etc., and the voice audio through the earbuds works fine. But if I try to play any type of music, whether it is streaming through YouTube or Spotify, or even playing a downloaded .mp3 file through the Google Play Music app, I just get the sound of hissing and stuttering in my earbuds, no music. If I go into settings on the phone and turn Bluetooth off and then back on, voila, the music plays fine and continues to do so until I power my phone off and on and then the problem repeats itself, again solved by turning Bluetooth off and back on. These same Bluetooth earbuds auto-connect and play music fine with my Xiaomi Mi Max 3 and with my wife's Huawei Mate 8. The problem is therefore with this phone, not the earbuds. Has anyone else had a similar problem?

I'm not experiencing this issue. Music/calls/youtube all play fine over bluetooth. I have the China version.
My Mate 20 X (China version, EMUI 9.0.0.137) are intermittent playing music through my bluetooth speaker, even the phone and speaker are next to each other. The speaker is fine playing music with my other Galaxy S8. The songs are stored in my phone, so the internet speed is not a concern.
Hey,
I think this very much depends on the pair of headphones. I have the Chinese Mate 20 X, and I own 2 pairs of BT headphones.
My skullcandy crushers work fine. Crisp, loud, in sync. No problems.
My Jaybird Run earbuds will only work for 1 or maybe 2 songs on spotify before losing connection or turning off. They are basically unusable. I'm not sure if it's the phone's fault or whether its more generally a bluetooth 5.0 problem?
I've tested my Jaybird Run earbuds on my old phone and I have no problem.
There are so many factors, its hard to say what's causing this and whether its the fault of the phone, bluetooth 5, or the headphones.
Same with p20pro ( same bt buds) to the point i just go to bt and disconnect and reconnect everytime beforeci start listening .
I m pretty sure its only happening with thid headset since i had a cheap bt headset before and it was fine .

Which buds are you using?
The P20 Pro is using Bluetooth 4.2
So I've done a bit more testing and have now paired my Jabra Active Elite 65t 5.0 Bluetooth earbuds with several other phones, running Android operating systems 7, 8, and 9. They pair and connect seamlessly on both calls and media. But on the Huawei Mate 20 x they connect immediately for calls, but they don't always connect for media playback. Like the chap above mentioned, this happens whether I am streaming music to the earbuds or playing music downloaded to my phone, so it is not a wifi issue. If I can't hear music going to my earbuds when the phone's settings say that I'm connected to them, I have to do one of two things. The first is to toggle Bluetooth off and then back on - in which case they music plays and will continue to do so until I've powered down and reconnected the earbuds. The second way to hear the music is to go into settings/developer options and change the default AAC Bluetooth codec to SBC, in which case I instantly hear music. I can then immediately switch back to the AAC codec (which my earbuds work with) and the music continues to play. There is no way, however, to change the 'default' codec to SBC, as each time you exit developer options it reverts to AAC. Perhaps Huawei could fix this in a subsequent firmware update and that may solve the problem. I'm receiving two more Huawei Mate 20 x phones this afternoon and I'll test it with them as well to see if the problem is isolated to the one phone or if it is a problem with all the Mate 20 x phones.

Your earbuds are using Bluetooth 5.0? That defeats my bluetooth theory.
I really hope Huawei fixes this with an update because it would be nice to use my earbuds with my main phone.
I'm having some bluetooth speak issues - BOSE speakers. However, I don't current;y have the time to find out what or why - Pairs but just doesn't seem to connect properly. I might try to investigate in December

How do active the jabra service background? I tried everything and could not solve the issue to connect to jabra apps to use my sound profile.

My model is L29
To set the Jabra Service to run in the background (or any app for that matter) go to Settings / Battery / App launch, scroll down to Jabra Service and de-select "manage automatically". That will force it to run in the background all the time. It only uses a tiny amount of memory. You will know when you've done it correctly when you put your Jabra's in your ears (which turns them on and autoconnects them) and you see the little "Jabra Service" icon displayed on the top left hand side of the phone.
The L29 I ordered for my wife's Christmas present arrived today and the Bluetooth media connection problem occurs on it just like it does on my L29. I've tried the Jabra's on five or six other phones now and the problem playing media audio only occurs on the Mate 20 x. Must be a firmware glitch.

Don't you have the same issue with jabra and mate 20 X? Do you have another jabra model than elite active 65t?

I do face the hissing and stuttering during play every time when I am near any electronic stores. This issue has been following me from my previous IPhone 8 Plus before getting this Huawei mate 20x.
After pairing up with huawei mate 20x, I still have similar issues like the description above. But it serves me well when I go for my run and gym. I still use wired earpiece while commute to avoid suspicious look talking to myself. Jabra elite active 65t, is my sports companion only.

Thanks. I've just bought thenm and I'm facing stuttering and interruption while watching prime video while in the subway. I previously had zolo liberty and had zero issues while in the subway. To be fair I always have two devices connected to the Jabra. I'm wondering whether that's the problem...but reading your answer I guess they don't seem to have a rock solid connection anyway.

I agree with that remark that you stated. Therefore, I always used a wired even though I have jabra elite active 65t in my gym while commuting.

Audio Codecs

So i ride a R1 and bought a Cardo Slimtalk bluetooth speaker system for my helmet, and one of the users in their forums suggested i switch the bluetooth audio codec, in dev options
So i go and change it from "Use system selection" which is usually "SBC" to APTx or LDAC and it switches back immediately, what gives? how can i take advantage of this?

The jabra seems to have aac, try that. Should work fine automatically, otherwise use the app if available on Android.
And if the dev settings won't stick, you can't force it otherwise. Some devices have apps which can be used for them and also to force things like that (Sony for example does this)

Bluetooth audio quality question

Hello. I change phones alot and have noticed that some phones(all android) have better bluetooth playback than others.
I had a oneplus 7 pro before this phone and the bluetooth quality to my truck was great and had no issues but with this phone the highs sounds scratchy or like if the speaker is bad. But if i connect it with a wire connection it sounds great. Everything with the 2 phones is the same. On both i was using the galaxy watch and pretty much the same apps. On a previous phone the note 8 i had the same issue but it was a different car. Seems like its the way samsung handles bluetooth.
Has anyone had this issue? If so was there a fix?
Thanks

What do you mean?
The only two things I think about is the codec used that may be different across devices, and the Bluetooth settings that sync the phones volume with the headset (the differences are noticeable).
Since no DAC is used in Bluetooth, I don't think it can comes from them, for a same headset.
On Samsung phones you should run the adapt sound process. Try this.
I tried with the sync volume off too and no improvement.
I looked for the adapt sound and my phone doesn't have that setting. Or is it something different?
It's in Sounds and Vibration 》 Advanced Sound settings 》Sound Quality and effects 》 Adapt sound
You have to do this in a quiet place and ensure to answer honestly. If you can't hear the beeping press no.
After doing this the sound quality is night and day difference.
Ok found it. Ill play with it a bit. Thanks
I've had issues sometimes with audio being piped through the "Calls" Bluetooth channel versus the "Audio" channel so worth checking as the quality is obviously night and day.
I also like enabling Dolby Atmos on my Note 10+ for music so worth playing with too. Additionally, I recently found Samsung's Sound Assistant app which let's you customize a bunch of sound settings so worth checking out as well:

Is there an easy way to tell if the audio is going through the call channel?

Easiest is probably just uncheck calls in your phones BT settings for your truck (and make sure audio is enabled). If the sound is still not great then this isn't the issue.
Sorry to respond to an old thread, but I was wondering if any of this fixed the OP's problem. I followed all the recommendations here and on other threads but have not been able to solve my recent Bluetooth audio problem. The sound has been terrible lately.
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 being fixed on my side.
From what i see online, people have given up on Samsung and opted for Rooting their Samsungs and installing Viper4Andriod.
Has any one done this and can confirm that it fixed the issue?

Anyone out there with True APTX headphones?

Gotdamn huawei mate 20x sounds like **** when I connect my ANC wireless headphones, I'd have to manually disable and enable Aptx which leads me to believe it's the gotdamn phone and not my headphones. Is APTX bugged? I NEVER, EVER though digital music can sound like a scratched CD

I have the same issue! Every since one of those 9.1 updates the Bluetooth in general has gone to crap. I found it that if you go into developer settings and change the sample rate to 44.1 kHz, it fixes the problem... So far. https://photos.app.goo.gl/iYm6PTULB3jMp1Cn9
