Bluetooth music quality

Super new here, I tried searching for my problem but I may just be blind. Thanks in advance for taking the time to help out.
I've got an 06' BMW with a witson android head unit.
The issue I'm having is Bluetooth music audio quality. Oddly enough Bluetooth calling isn't a problem. The upper range of sound is distorting. Don't know if this makes a difference or not, it's connecting to an iphone *hides under table. If I listen to the radio or to a cd (like it's 1997 or something) I don't hear the issue.
I've gone into the factory settings, and adjusted the BT volume up and down and found no change. I've changed all of the volume options, and found no change. I've tried changing the amplifier settings as well and have found no change.

Have you tried factory settings, and turning down BT master volume. Mine was set well above the others, which could cause issues when in higher volume ranges.

Yes, in fact I was super excited when I searched and found the factory settings code, and that the bt adjustment was in there. It was set to +18 I've since set it to 0 and saw no improvement.

I guess my question is this
Clearly, a setting isn't going to fix this, should I just install a new Bluetooth app, or is the Bluetooth app essential to the operating system and I should just install a new operating system??

HI
I have erisin 2046 and my bluetooth music is scratching hard.. quality is very bad
set the master volume down already in factorysettings (126) but nothing changed.

Sounds like a firmware update is required... maybe to android 5.1? If only people answered more often about doing them... (I have no idea how)

I have two units (MTCB KLD, MTCD KGL) and an old clarion HU with bluetooth.
This problem exists all three units. It's not a firmware problem, problably MCU related issue.
I was digging many forums about this, but I cannot find solution.

I have a MTCD unit which is functioning well but the BT streaming quality is quiet bad.
It's quiet easy to do an A and B comparison with our android units so it will be obvious but if you didn't know, you'd think it's ok.
I just think bluetooth streaming quality is generally bad if you don't use APTX

probably there is a problem with smartphone. When I using android one, there is no distorting in upper range. However, when I use iPhone SE, it's hard to hear distorting sound and quality is really bad.

I have the same problem. Very bad sounding, upper range is distorted. I've tried 3rd party Bluetooth apps, but it doesn't recognize the unit as having Bluetooth. Probably cause the Bluetooth chip is in the MCU, and is not actually part of the android software. That's my guess.
Does anyone know if a Bluetooth dongle to the USB will work? I have a spare one laying around.

The bluetooth module connected to the MCU.
The MCU provide the Bluetooth audio stream to the Android OS.
The Bluetooth app can control the BT module through the MCU.
So there isn't direct link between the android OS and the bluetooth module.
Sorry my bad english..

Yeah that's what I was trying to say, maybe we can switch out the Bluetooth module?

I tried, didn't work. I used a usb bluetooth dongle from my pc. Works on the pc, not on the unit. Maybe you will have better luck. Mine still sounds like garbage.

Here the same Problem! Very, very Bad.

Anyone had any luck with this topic? very annoying.

i have this problem on my MTCE XRC unit.

same problem on AE0273B

Audio streaming over Bluetooth App from my iPhone (say from Pandora) is noticeably worse quality than using an app on the HU (say, Pandora App on HU). Do not have this problem streaming to other HUs (like the one built into the Prius) or my previous GTA Kit.

BT keeps stopping

I just noticed that phone is not connected to my bmw car kit most of the time, because BT keeps stopping. Now this is a show stopper for me. This seems like yet another cheap Chinese device which has nothing to do with Nokia.

Any other people who have the same problem? I do need BT all day for headset and connection to an OBD-device..
Gesendet von meinem EVA-L19 mit Tapatalk

I'm connected all day and night to a Xiaomi Mi-Band 2. BT never disconnects from it.
Also when I'm driving, I connect to a 2nd device which is an MPOW bluetooth receiver connected to the car's aux port. Also never experienced the BT stopping or dropping the devices (2 simultaneously, yes, using Oreo beta).
Dunno if this helps or qualifies to compare what you're experiencing.

I experience the same Bluetooth disconnections while using my Parrot carkit. Unusable for now. Running on Nougat oct security update

People report about car connection in other phones too, I think it's might be a OS problem. For me I use bluetooth headphone, never get disconnected. But sometimes have audio drop out when moving.

I have a slightly old ford kit.
Yes Bluetooth on it seems a hit or a miss. Connects and the audio comes for a few seconds and then just stops. Calls or audio just stops to work
I would like to blame the phone since my old Nokia 808 and galaxy S6 work fine but my brother's one plus 3 has the same problem.

Bluetooth audio plays just fine over my Volkswagen stereo BUT the play/pause/skip doesn't work and the song info (metadata) doesn't display.
Really frustrating as it was working so well before on my Huawei P9.
I'm running 7.1.1, really hope Oreo comes quick to fix this ?

This was the not very useful advice from Nokia support.
You may have guessed that it didn't work and I'm back using my Huawei... Looks like this phone will be going back to the seller by the end of the week.
Unless Oreo magically comes to save the day. Anyone want to place a bet?

Nokia implemented Bluetooth version 5 so maybe there is a compatibility issue.

Thanks but it was my understanding that Bluetooth versions are backwards compatible? It's a 2012 car stereo and I've tested 2 other Nougat 7.1.X devices which work perfectly.
Music does play from the Nokia but it's the controls and song info that is missing.
I'm back to using my Huawei P9 as my daily driver because of it

So it seems as if there are mostly problems when running Nougat, while it's working under Oreo.
Will watch this thread before going for a new handset. Quite unsure between Mate 10 non-pro, Nokia 8 and OnePlus 5/5t. Dual-SIM is absolutely necessary for me, in Germany they use band 20 (800 MHz) in many areas. As I'm using a Samsung Gear S3 and that OBD-device in my car and furthermore a BT headset, a bigger battery or more efficient device is what I'm looking for.
Seems as if this is getting hard to decide...
sent directly from my mind using my upper extremities..

I'm seeing issues on Nokia 8 with Ford audio in my van. It's not that it disconnects, but when skipping to next / previous song in Play Music, progress indicator continues to move, but no audio comes out unless turn off Bluetooth and back on. Happens when using onscreen skip button, or steering wheel skip buttons. Same worked fine with Nexus 6.

I am using my Nokia 8 for about a week with Ford Ranger (about one year old) and completely there is no any issues.
Regards

A workaround (of sorts) for me is to cycle through the inputs in the car dash (bluetooth, aux-in, fm1, fm2, dab, then back to Bluetooth) which brings audio back and the skip/next buttons work as intended.
Should also clarify that it is not just Play Music. Same issue in Castbox, so not app specific.

Fired up the Nokia 8 last night and see there's a November security patch being rolled out.
This seems to bring my kernel version up to Nov 9 - hopefully this might have an effect on the Bluetooth compatibility and stability?
Haven't had a chance to test it yet but it's going back on Saturday morning if not fixed...

I have only connection problems with my Parrot 3100 carkit. Connection drops when calling. Bluetooth connection drops randomly. Stays connected when not calling. No issues with other Bluetooth devices.
The November update did not solve the carkit issue. Unfortunately. My hopes are on Oreo..

My problems are still persistent on the new November kernel.
I feel like this will be a forgotten device once the Nokia 9 is released in the New Year...

Would any of these Bluetooth developer options help those having issues?

I believe these are Oreo specific and despite the fact the rollout began yesterday it's yet to hit my phone. Fingers crossed, I've extended Nokia's deadline until Monday ?

USB-C to 3.5mm jack problem

Hello, I got my P20 Pro 2 days ago. So, here's my problem. I got a pair of HyperX Cloud II and I want to use them with the phone. When I plug them with the included dongle, the headset icon shows for a second then disappears from the notifications bar. I should mention the fact that I can use the included earphones and some other casual earphones. The interesting fact is that I can use my Cloud II headset without any problem(other than the fact that the volume is quite low) on my mate's Xiaomi Mi 6 with the same dongle. What do you think, is there anything I can do about it, or should I go wireless once and for all?

go wireless if you have the budget, for me i still prefer wired due to i'm too lazy to charge it, i've used the dongle with my MI in-ear pro, and so far it works as intended

I found the headset wasn't always detected and I had to add a setting in developer settings
I have 'Disable USB Audio Routing' set to off and 'Always prompt when connecting to USB' set to off.

Turns out you can use this headset with the phone, but only if you plug in the microphone, and that's a huge problem for me, as I used to casually wear them wherever I'd go. Since I bought the phone, I have switched to some in-ear headphones and I learned to live with this.

Will it be the same with all adapters?

Think other adapters will work with the hx cloud (no mic)?
Cheers

Solution
Hello everybody
I have the same problem with my hyperX cloud 2. To make it works you only have to plug the microphone in headset and after that plug it in the phone.
If you plug out the mic, headset will not be recognized again.
Hope it will be helpful for you. Cya

I have tried with adapters from: Mi 6, Pixel 2, U11. It has to do with the OS, as a matter of fact, they worked just fine without the mic plugged in for the other phones.

But without the mic, with the other (not stock huawei) adapters plugged in to the p20 pro, it still didn't work?
Just making sure it's not the adapter.
Thanks

Nope, the P20 Pro wouldn't detect the headset.

P20 Pro does not detect my headset or dongle
I have this problem and until now I cant find a solution. Phone is charging with any charger though and it just happened all of a sudden. I already tried doing a hard reset but no good. I am using the Europe version. Single Sim GPU Turbo updated.

Can confirm plugging the mic into the headset solves the issue.

Same headset here. If you don't want to use them whit the mic in, use Lesser Audioswitch app. You can choose the audio output source with the app.
Work for me.
Also, don't forget to manually switch back to speaker after you unplug your headset.

Has anybody discovered a fix for this yet where you don't have to plug in the mic? I just got a P20 pro and it is disappointing that I am unable to use my headset with it.

HUawei P20 Pro not able to detect headphones?
I've been using Apple headphones connected to the Huawei USB-C adapter on my Huawei P20 Pro....it was working fine for at least 5 months.
But last week when I plug in my headphones the icon shows up for a second, then disconnects in a few seconds. Now it's a consistent problem.
Has this happened to any of you? I don't know if it's the adapter or my phone...
Thanks in advance to anyone who can help!

Hello enable dev options / tap 5x in About phone-Built number
Than in dev options enable Always prompt when connecting to USB.
Hope this helps I got mine working

bluetooth issues

I am having bluetooth issues where phones tends to forget about the paired devices and I have re pair them all the time.
Is it me or others are having the same issue? And if someone was able to find a solution to the issue?

Mine seems to have been fixed after updates

I have the same issue with my car

Which N9 version? exynos/snapdragon?
Which software version?
I'm using exynos with N960FXXS2ARK3 and no problems

If you are rooted, install magisk module called libsecure_storage ,it will fix BT pairing issue.

I don't have this per se, but I have a problem where it will regularly connect a phone/music device (car aux adapter) in only phone mode, and I'll have to disconnect/reconnect twice to get media audio...and even then sometimes it will use the "phone" codec that sounds like CRAP for media. Will have to reboot phone to fix that.

Serious problems with bluetooth

Hi,
I hope to get here some suggestions....
I change from a SONY XPERIA XZ Premium to Huawei P30 Pro. With my SONY device I have never a problem with my Fossil Smartwatch and BT-Headset.
Now, with the Huawei my smartwatch is not able to connect the phone. Only once I got a connection, after I make a factory reset of the smartwatch. After going in flight-mode an reenable the connection, the phone see my smartwatch, but does not connect to it.
Does anyone have an idea what's going wrong?
Is there a serious support-page from Huawei to get a real support?
Thank you

In all honesty I've had three Huawei/Honor phones and they all have had issues with connecting to my Fitbit. It's very intermittent sometimes takes a while to connect. Some days it doesn't at all.

I'm checking and testing some powersave-options - it is very unclear. I think there must be the reason for it. Must make exeptions for wearOS and maybe the problem could be solved.
Never had this "problems".

Never really had any problem with my Mate 9 Pro and so far my P30 Pro works well too. Only tried my car and Bose Quiet Comforts so far thought.

You have connected only one device. Smartwatch AND headset/caraudio at the same time is/was the problem.
As I said, I've make some changes in the power-setting regarding the WearOS-app.

Using 3 Garmin Smartwaches/Tracker, a car hands free, bluetooth speakers and headphones without any problem so far.
Also did not had any problems using multiple at the same time of these together

i had problem connecting my P30 Pro to my car, it can identify the device but prompt for password that P30Pro never response!!

Huge problem
connects to a Bluetooth headset but there is so much stutter that's only one problem! The major problem is that it will not make Facebook or Whatsapp calls via Bluetooth and even if I click the Bluetooth icon it switches back to local speaker. I tried everything
Unpair and reconnect
Reset network settings
Clear Bluetooth cache memory and data
Everything!!! Still no solution, I even factory reset the phone and still same problem, I tried 5 different Bluetooth headset also. Please help with any suggestions

did you looked in the pairing options, whether the device is using phone AND media protocoll? Doesn´t seem like that

Yes I have, YouTube works via the Bluetooth, phone calls work, pretty much everything else does except calls via apps like Whatsapp and Facebook messenger, Skype etc

Did you try changing to 5g wlan instead of the 2,4g I never had that problem in 13 years apple. There also it worked perfect at 2,4ghz.
Dont ask me why that does not work for huawei p30pro. Btw. Samsung s9 also does not do a good job at 2,4.so maybe a android10 thing. Bluetooth also works at 2,4ghz...but how can that work for apple??

Had this Bluetooth issue since day 1.
Using Bluetooth to anything works fine for 20ish mins then stops.
Disabled all battery restrictions like we have to do with the apps to keep them open (in both places) I did a general one, still the same issue.
It's stupidly frustrating and so damn annoying.
I've been gutted about this phone since I got it, sadly stuck in a contract for another 12 months
