Bluetooth audio quality

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).

Is APT-X Working or Not?

Hey guys,
I'm running freedom os and recently got a pair of mdr-1000x's. The headphones support aptx and aptx-hd, as does the ROM. Is there a way to determine what codec is in use over bluetooth? Everything sounds amazing, just wanting to make sure I get the best bang for buck.

It's working for me. I have the LG-HBS-780 BT neckband set and was able to tell it works by trying it on 2 different devices. My Moto X Pure doesn't have AptX enabled but FreedomOS 2.9 does. The sound difference was incredible!! I don't have ARISE / Viper4Android installed, decided it wasn't needed.

also for me with m1bt philips
lastest beta 8 from oxygenos
developper option, network, lastest choice is support hd aptx/aptx, check if enabled
regards

Yep there is noticeable difference! (Changed from Open Beta 8 to 4.1.5)

I'm assuming this toggle is available only on Beta 8? I'm on 4.1.5 Freedom OS and I'm not seeing it under dev->network.

My own MDR-1000x work fine in beta8 BUT when WiFi is also active might sometimes have lost packets (and sound cracks), that gets fixed if I disable WiFi.
Quality is definitely better than on default SBC but is still clearly inferior to a wired connection (as long as you are using a good FLAC as a source). So I am waiting for AndroidO and LDAC (which 1000x does support :good: )

If you're on an open beta > 8, or a Freedom CE build based on a >OB8 build it should be working. Stable Freedom is just based on the stable OOS builds and it does not work. I found a magisc module that added the drivers, but I wasn't convinced it worked right so I gave up on it.
If you use a catlog reader you can search for codec while you're playing audio through blutooth, it should say aptx or SBC. If it says SBC then aptx is not working.

Was able to look at the logs and see SBC. I'll look at the magisk module. Thanks for the heads up.

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 ?

Huawei Mate 10 Pro and bluetooth headset with distorted sounds

I bought a new bluetooth headset with APTX, but unfortunately the Huawei Mate 10 Pro phone doesn't work properly with it. If I use the equalizer bass boost in any MP3 player, the sound becomes distorted. I can choose only SBC or APTX bluetooth audio codec on the developer settings and this fault is present in both settings.
The headset works perfectly with other types of devices, for example Huawei P7 with Android 6, Samsung Tab A6 with Androud 7.0 and Huawei P20 Pro with Android 8.1.
Did anyone else experience same thing?

I have more or less the same problem..
Low volume and poor quality..

What version are you running? (Kernel compilation date) this was solved for the European variant a few months ago already.
Anywho yeah you only will be able to choose between SBC and aptx since EMUI doesn't support AAC yet. (Even though the Huawei free Buds supposedly works with AAC ?).

4.4.23

My phone improved Bluetooth quality with an update that came around begining of begining of April and it was released to everyone around May, it was the B137 for C432 (European variant), and I think it got better now with the B142 (may/June update).
Try to see on firmware finder if there is an update available for your phone, and if you can force the ota, cuz this should've been solved long ago.

My phone (C432 too) has B142 firmware. I refreshed it last week from B135.
Now the build number of my phone is BLA-L09 8.0.0.142(C432)
I must wait the official upgrade, otherwise I will lose the guarantee.

Tried resetting the phone back it its default?
Every update I made wasn't via OTA it was a clean install via funky Huawei, so idk if this matters.
Send your phone to repair if it doesn't get better

Just have some awesome news, B146 update finally adds AAC support for BT audio.

distorted and very thin sound when using the equalizer was solved after getting android pie 9.0.0.159 (c185) yesterday here in KSA. before i have the same problem in all Oreo firmware. :good:

Interesting, my experience is the opposite. Nice audio with 8, dirty and tinny articles in the audio after.

Mi 8 Low Bluetooth Volume

Hello Everyone!
So after changing from iPhone 8 Plus i bought an Mi 8 , brand new , and using Oneplus Bullets Wireless.
I've noticed that the Bluetooth audio is so low that i can hear others better, than my music.
De paired, re paired the devices, activated Absolute Bluetooth Volume, tried restating the phone, i made my region To India, tried everything what i can find on the web, but still no changes.
Is there any Kernel or Rom which removes this feature? I'm using the latest MIUI i would stick with the original Rom so a kernel fix would be great. If its cant be fixed by kernel can you guys link me a good rom to use?
Thanks.

I had this problem.
I downloaded R.E. equaliser from the Playstore.
Now my Bluetooth volume and speaker volume are great.
I used the presets but turned the gain up,that's all.
This is a great equaliser for people like myself who aren't rooted,a couple of pounds to buy but well worth it.

Any other solutions?

I also have this issue. Did anyone find out anything?
