Can someone comment on the bluetooth audio quality on OmniROM 4.4.2? I tested it today and, to my ears, it sounds much worse than 4.3 (either CM or Omni).
I tried searching around but there were conflicting opinions. So I'd like to know what people around here think.
I too feel that audio quality over Bluetooth was better a few weeks ago.
There were one or two builds where it got really bad but it's OK now but not as good as it once was.
It may have been the use of GravityBox which I used for two or three nightlies before canning it again but I'm not sure.
I use Omni on a Sony Xperia Z so this is only in regards to this phone.
I'm now sure that the audio quality over bluetooth is worse than it was a few weeks ago.
Today I flashed CM11 to compare BT audio quality and on CM it was so much better (like it was on Omni when I started using it).
On Omni there is almost no bass at all and highs are a bit distorted whereas on CM audio over bluetooth (Xperia Z with Sony SBH20) sounds almost identical to directly plugged in headphones.
Don't know about Sony but on oppo the problem was using too old blobs which derped the ACDB setup.
So this can be really a device specific issue
Unfortunately this depends on the device maintainer to
1) test and confirm it
2) try to fix it
I dont know what the maintainer situation for the Z is at the moment

humberto is coming up to speed, but the Z isn't particularly well maintained right now. Doesn't help that I can't even FIND mine at the moment... I'm not sure where it went.
Most of the Z guys are trying to solve the camcorder issues properly. (I don't like Thomas' approach, there's got to be a cleaner solution esp. since all third-party cam apps work OK...)

If it is a blobs issue, can anyone comment on the I9300 (Galaxy S3) and bluetooth audio?
I have newly installed yatour box with bluetooth receiver on my car and the sound quality over bluetooth from I9100 with Omni is really bad.
The sound is almost crackling on some quiet places. Sound is perfect if connected to yatour's aux input with cable.
I have to test it with another transmitting device (without Omni) to rule out problems with the bt receiver though.
Bluetooth audio quality is pretty awful on the N7000 too, with my sony mw1 the n7000+omni 4.4.2 is distinctly bad compared to any other bluetooth source I have (phones, laptop, pc).
Just to open with this - I really like this phone and have been enjoying using it. Aside from the fairly poor WiFi range and the flaky NFC it is otherwise a really nice phone. There's just one other issue I have which is extremely frustrating:
I can't use it with my Airpods. Or at least, I can connect it but at some point the sound will crackle and cut off. If I wait it will occasionally crackle and come back on again but will cut in and out in a way that would drive anyone mad. I've tried fiddling with Bluetooth settings in developer options but it doesn't seem to make any difference. I've even tried a factory reset.
The Airpods work absolutely perfectly with every other device - no issues with the iPhone (expectedly) nor the S8, G6 or even my laptop. I can't 100% rule out a fault with the Airpods but given these facts it seems highly unlikely.
I wondered if anyone else used Airpods and had experienced issues and found a solution.
Not too interested if you've had no issues with your device, nor what you think of Airpods - I just want to see if I can get to the bottom of this, or the Nokia will have to go back.
Many thanks
Similar problem
Got a similar problem with my apt-x receiver.
Every few minutes the connection drops for a very short time.
The airpods don't support apt-x, but maybe it's the same problem.
My receiver shows a connection via apt-x, , but you can't find any apt-x support in the Nokia 8 specs.
But I had no problems with a friends portable speaker (non-apt-x).
I went back to cables

I’m wondering if the Nokia 8 just has rubbish connectivity, generally. If the Bluetooth chip is part of the WiFi chip then this would figure as it has the worst WiFi connectivity I’ve seen in recent years
Are you running Nougat or Oreo? From what I've heard, a lot of the bluetooth issues have been fixed in Oreo.

I wonder if yours is wonky, my Wi-Fi is excellent and i get get 75Mbit down 19Mbit up over 5Ghz through 2 brick walls, a floor up and at the opposite end of the house, i have not missed any payments using contactless via NFC and Bluetooth works fine via an Anker Bluetooth speaker and my JBL Bluetooth headphones.
Sorry for digging an old thread, but I still have the same problem even after a bunch of software updates.
My issue with the AirPods is that they do not work after they connect. I take them out of the case, they connect (as expected), but as soon as I start playing something the music/video pauses and the sound switches to speaker (if I press play again it plays out loud). To make them work I need to go to bluetooth settings, disconnect them and connect them again. Then they will work almost flawlessy (minor intrerruption from time to time).
I have no issue with other BT speakers. I also use the AirPods with an iPad and laptop and no issues there.
My Nokia 8 software is up to date. AirPods firmware the same (checked on the iPad).
I tried re-pairing after each software update. I tried changin BT settings (absolute volume - dev settings; contact sharing and HD Audio: AAC) but no improvements.
Any ideas what else can I try?
Search for Oreo and Bluetooth problems. It seams to be a general issue for this Android Version. I have problems connecting my Phone with the car, too.
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?
https://www.youtube.com/watch?v=x-sifkojUqw
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....
Hi, got a Huawei Mate 10 Pro BLA-L29 8.0.0.136(C185) and a Shanling M0 as a Bluetooth receiver. When I get them connected using LDAC, there are two menu sections where I can set the audio quality to be fed to the M0. One is the Developer Options where, apart from selecting the BT codec itself, I can set sample rate at 44.1 to 96 kHz, bit depth of 16 to 32 bits per sample, and stream bitrate at 330 to 990 kbps. These settings behave in a weird manner, always reverting to default every time I disconnect the BT or even while it's connected. The other instance is the properties of an individual BT device where I can set the LDAC playback quality to either "Optimized for audio quality" or "Balanced audio and connection quality".
Problem: if the BT device is "Optimized for audio quality", I only get decent transmission if stream bitrate is set to 660 kbps or lower in the Developer Options. Inversely, if the latter is set to 990 kbps, it only works decently if the device-specific setting is "Balanced audio and connection quality". If both are set to maximum audio quality, the playback starts gagging violently, interruptions happening up to twice a second if the phone is active and like once every five to ten seconds if the screen is off (the two devices 5 inches away from each other with nothing but air between them).
I brought the Shanling M0 to the nearest Sony store and paired it with a demo phone with LDAC audio quality set to 32/96 at 990 kbps and it worked like a charm without a single hiccup.
Anyone else has this issue and/or aware of a fix?
I have been to a number of stores since the original post and was able to pair my Shanling M0 to various devices:
1. Huawei P20, Android 8.1, Bluetooth 4.2 - same problem.
2. Samsung Galaxy S9+, Android 8.0, Bluetooth 5.0 - no problem.
3. Samsung Galaxy A6, Android 8.0, Bluetooth 4.2 - no problem.
Apparently, Android version is not responsible for the malfunction, neither is Bluetooth version. It's the manufacturer.
Crap, crossing fingers about having this issue fixed. Have you reported it to Huawei customer service and Shanling's one ?
Thank you for the feedback. I'm interested in this small DAP (nostalgic for my beloved Sansa Clip), even if I'm quite sure I probably won't use the Shanling M0 as BT receiver.

If you ask me, you should just grab your money and go get it, because it works fine with other phones than Huawei. Even with mine, if I set it to "Balanced audio and connection quality", it's doing great. Actually, the LDAC standard bitrate of 660 kbps is amply sufficient to deliver music from major streaming services like Google Play Music. Whatever the problem is, I don't believe it's Shanling's fault, because the intensity of gagging depends heavily on whether the phone screen is on or off, which has nothing to do with connection quality.
As to the DAP itself, I find its sound signature and stage presentation nothing short of amazing, at least on par with my favorite Hidizs AP100 and far better than vivo Xplay6 or anything else I tried. Sansa Clip+ is nowhere near. The way I feel right now, I'm far more likely to ditch the Huawei phone than the Shanling DAP, because there are reasonable alternatives to the former, but not the latter.

Indeed, I started following Head-fi.org's thread few weeks ago, this device looks great.
I currently own a Cowon Plenue D for more than 2 years, I'm quite happy with it: relatively small, great battery life and sound. But I'd like to have a smaller good DAP I can bring with me when I run, or simply don't want to suck smartphone's battery. I bought a Sansa Sport Clip+ (BT DAP) one year ago, crappiest DAP I ever met...
What's your battery life experience using BT head/earphones wiht this DAP ?
Hello there,
Just to share the using LDAC experience with a mate 10 pro (BLA-L29 145 (C432))
I have a Sony headsets (WH-1000XM2) and it works just fine, I'm able to use LDAC perfectly, sound is very good but you need to be close to the phone, 5m apart and it starts to break.
I know its not the same situation, but this is my experience.
Best regards.
And the volume?
Mine with my sennheiser 4.50 BT NC is very low..

I have no such experience, I only use M0 as a BT receiver with wired IEM connected to it. I never even bothered to measure battery life, since it's more than two days of my regular use, i connect it to a USB port earlier than I need to charge.

If you want to control volume on your headphones, you need to set it to maximum on the DAP. The rest of it will be the responsibility of your headphones' integrated amp - if the volume's too low, then it's just not powerful enough, there is no way a bluetooth source can fix that, as it does not transmit loudness.

Thank you very much indeed, because that's exactly the diagnostic step that I missed. Need to try that to locate the problem more precisely. Are you sure that the LDAC playback quality setting in your bluetooth device options was at "Optimized for audio quality"?

Where is possible to maximize the volume on the DAP? Simply with volume buttons?

I would suggest that you go to the Shanling M0 thread on head-fi, there's a company representative on that forum who's very cooperative, you should describe your issue to him. I wish I could give you a hand, but my experience is limited to operating the volume wheel on the DAP.

Yes... it has to be... or it wont use LDAC at all... it will use APTX or something else... LDAC is only used on the setting "Optimised for audio quality".
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 !

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
