Android O bluetooth problem with car audio. - Nexus 5X Q&A, Help & Troubleshooting

Hi. I have a Nexus 5x with the latset Android O preview image.
Since I started to test this preview I have noticed that there is a problem with audio to my Kenwood car audio.
With Android 7.1.2 there was no problem. When i start my car the phone connects to the car audio via bluetooth and when I try for exempel Spotify there will come sound with no problem.
Now, when I try this with android O there will come no audio. The only fix for this is if I open up developer-settings and change soundcodec for bluetooth to SBC. Then the there will be sound from the car audio.
Ok, so now I have the fix for the problem. But this is only temporary. Everytime I leave the car and come back I will have to do the same change in the settings.
So, is there a way for me to change this for good? Like change a configfile or similar?
Do anyone know where the info is saved? If so I geuss I could try to change it that way and save the info.
Hope you have understood the problem and that my Swedish SchoolEnglish was understandable...

This is know issue on Android O. Google has already mentioned this in Bugs list or the release.
If you need Bluetooth audio, you should go back to Nougat.

Well. I know it's an known issue. Thats not the question. The question was if anyone knows how to make the settings permanent for the bluetooth audio codec.
//Tommy

I have a similar problem with my Moto 360 Gen 2 running Android wear 2.0
I do the initial setup and everything works great, but if the watch disconnects from the phone because of distance or whatever, it will start prompting for the PIN to re-pair, but it rarely works. I usually have to factory reset the watch, forget the watch in the Android Wear app and start over.

[Q] Bluetooth A2DP issue with Car Stereo

Ok, so here's the deal. I have a rooted T-mo G3 (D851) on a stock rom, out of the box it's been awesome to use with my Pioneer AVH-X2600BT head unit in my scooby. I was messing around with themes a short while ago and then the bluetooth stopped working intermittently. From what I can tell the mix-rate of the A2DP stream changes from 44k to 3hz and all you hear are beeps at multiple amplitudes. The beeps are playing out of the buffer in the head unit until it empties then it resets the connection to the phone. It still plays out these beeps until it's empty even if I disconnect the phone from the head unit.
I don't have this problem with two other iPhones. And previous to my screwing around, it'd work flawlessly since a bought it (launch day.)
Could I have screwed up a mixrate setting someplace? I do have a custom mixer xml for boosting headphone port and speaker audio but I never touched the settings for the bluetooth driver.
This behavior is intermittent and it matters very little what content I'm playing through it. I do notice that when this is happening, no metadata or control is capable through AVRCP either. (i.e. Pandora app can't connect to the phone, no album art, etc)
Sometimes it'll stop doing it and play normally for the rest of the session (drive) after a few minutes and everything is normal. Sometimes it doesn't do it at all and sometimes I can't get it work normally at all.
Here's a video showing the behavior:
http://youtu.be/qYuuTG01x1E
Reset your Bluetooth on your headunit and pair it again with all your bluetooth devices.
I had a similar problem with my LG G3 and my Pioneer AVH-8500 where my Pioneer will not recognize my LG G3 anymore but recognizes my Note 3.
I fixed the problem by resetting my Bluetooth on my Pioneer and had to pair all my devices back to it again.
You will have to look into your Pioneer manual on how to reset your bluetooth.
Edit: I just remembered something.
Did you happen to update or change your firmware.
Some KitKat firmwares are missing the Bluetooth Metadata and will not function properly.
Use autoaudio download it from playstore. This fixes my problem on metadata
Hey thanks guys.
I reflashed the bt radio in my head unit and the problem so far has seemed to go away. Metadata and everything works again.
I appreciate the heads up from another pioneer user.

How exactly did you reflash the bt radio? I have the same head unit and am having problems with it dropping the bt connection to my G3
I just got forced to upgrade my LG G3 to Android 5.0 and it completely screwed up my Bluetooth audio connection in my car.
Bluetooth sync to home audio playback is fine, but BTooth audio is completely corrupted with the Pioneer AVH-X2600BT.
I cant find the instructions on how to reflash my stereo firmware to reset bluetooth settings. I cleared my bluetooth devices in the stereo setup, but to no avail. Can you point me to instructions on a reflash?
I am having the same issue. I have 2 other bluetooth devices that my G3 will connect to and playback is fine for as long as I have battery life. But when connected to my Pioneer AVH-x2600bt, I get constant skipping after 2 minutes of playback. I can pause it for a couple of minutes and when I start playing again it's fine for another 2 minutes. I have done a hard reset on the Pioneer and reconnected my G3 but no change. I have unpaired and cleared all of the bluetooth data in my phone and reconnected, no change. All of the Kit Kat OS devices I have still work fine with the Pioneer but none of the Lollipop devices work. I emailed Pioneer, their reply was for me to take my deck to a service center. That will do no good. One of two things needs to happen, Google needs to update their bluetooth firmware or Pioneer needs to update the firmware for the AVH-x2600bt. Until one of those two things happen I guess I'll be using stone age technology, an auxiliary cable.
Thank you, that is all.
Hello
I can't sent the music to my car radio according to the version of Android. In version 5.0 with different kernel that doesn't work, and with 5.1.1 (blisspop) it works. I 'm preferred the custom rom because I like some features. Someone have a solution or an explanation of why?

O update and bluetooth audio

So I had been on the beta version since it was released and participated a few times in the thread here: https://forum.xda-developers.com/pixel-xl/how-to/android-o-beta-issues-t3609335 and others were having the same issue.
The issue is no song/artist information being displayed on my touchscreen stereo, and I cannot use the stereo to pause/skip to the next track (I have to do it through my phone). Ive tried a local audio player, Google Music, and Pandora all to no avail. The deck is a Pioneer double-din AVH-P8400BH.
In my daily car, my phone bluetooth name appears and I can change song ect thru the deck. It is not a touchscreen and it probably 10 years old.
Ive gone into the bluetooth settings and have tried changing the AVRCP from 1.4 to 1.6 (neither work), and audio codec from default to enable optional (neither worked).
Anything else I should try out?
TIA

Ill have to give this a shot!
mine has awful streaming. It has so many skips...snags...audio blanks...whatever term you want to call it....its not "uninterrupted".
I was hoping google IMPROVED Bluetooth. I don't understand why they have this struggle to be honest. Its 2017....Bluetooth is not new technology.
Maybe they should stop expanding their department to provide data to the government to spy on private citizens using smart devices, and they would use those resources to fix bluetooth
Pioneer brand head units in particular I have seen Bluetooth streaming issues when paired to flagship model phones for years...even back as far as my LG G3. I got a Kenwood head unit instead, never had an issue.
As far a the Pixel XL and BT streaming...I have only had issues with dropouts zap sounds or pops, when i am out mowing my back property with my tractor...phone in pocket and BT headphones on. But my previous phones did this...most certainly due to the railroad nearby and high rise high voltage power lines and towers that are above me in that area.

Pioneer uses a cheaper bluetooth and never updates the firmware of the chips to fully support the available Bluetooth profiles even when they are developing their units and new profile updates are available. I have had a very long and annoying history with them to the point where I was in direct contact with their build team after all my complaining. That was back in 2012. Never used another of their products again. :good:
I have the same issue on my Chevy Colorado 2017. Everything works fine on Spotify on my Huawei Mate 9, and iPhone 7. It also worked fine on 7.1.2. Spotify works and music comes through but no info is displayed. I unpaired both things with no success. Frustraring.
I tried unpairing mine as well, no luck either

Have you tried unticking "media" in the profile hitting ok, going back in and ticking media again?

I have not. Ill give it a shot today.
No idea if this problem is related or not but might be worth a check if you have time. First time I put Oreo on my phone it was fine. Then I screwed something up and just ADB flashed the image again. Everything was fine until I tried bluetooth a few days later. It wouldn't connect until ticking that media box many times. Then I flashed the image again and it worked fine again.
So I just got the 8.0 OTA (not on beta). I see in the dev options that it shows what BT codec it is using.
I have noticed that only the option "Bluetooth AVRCP Version:" is the only value that changin it does it stick. The other setting appear to be on auto and revert to auto depending on what device u pair supports.
My first test on my Kenwood KDC-BT762HD it paired fine and it said it was using AptX. Streamed for a few min fine. Then after I got back in the car and it auto paired, music started skipping every several seconds. I turned radio off then on to repair it and it started streaming fine again....but was using SBC according to Dev options.
When I changed AVRCP version to 1.6.....it connects and uses AptX fine. However, the radio display no longer displays the BT media metadata(title/artist), but the controls on the radio still work. I change to AVRCP ver 1.4 and that restores metadata, but then it uses SBC again. (using ver 1.5 results in SBC and no metadata).
I don't really care about the song info not being displayed on my radio....but definitely seems to be something fishy with BT in this new update.
EDIT Update: so now I am noticing it auto re-connecting and using SBC all the time now. WOnt use aptX unless i delete the device and re-pair it. then it works for a few reconnects, but then drops to sbc cagin.
Thanks for posting, I won't be updating. The Bluetooth has never been right and now seems to have regressed.

i agree and although i dont get the proper song listing on my car stereo it seems everything else is better. on nougat my BT headset i use for work all day (moto buds) would often stop connecting properly and i would make a call and have to select "phone" then "headset" again to get audio back on headset and om Oreo it happens less frequently

If you switch to a rom that uses the CAF based bluetooth (all lineageos based ones should, crDroid does for sure as that is what I use) implementation this won't happen. Still haven't been able to track down exactly why, but for now I'm sticking with CAF based ROMs to avoid this.
Do any of you guys having this issue have an Android wear watch? I've had heaps of issues with Bluetooth streaming being all "jittery" and just skipping since the update. However, I found this is basically completely fixed when I turn my android wear (LG urbane) off, or at least the Bluetooth on it.
Tried all the developer options for BT but hasn't made a difference. At the moment, my solution is turning off BT on my watch when I'm listening to music. Bit crap but it works.
I have factory reset the watch and cleared BT cache on pixel.
Any other ideas?
Is anyone else still having problems with Bluetooth on Oreo? I was hoping the official 8.1 release would help me, but I'm seeing no change. I have a Kenwood BT952HD, and experience issues similar to what the OP describes. Audio is plays fine, no unreasonable stuttering. But I get no song info, and can't skip tracks. Also, the pairing isn't as automatic. Every time I turn on the car, I have to wake the phone up, and wait for the pairing to complete, which takes longer than usual.
I've tried playing with the AVRCP settings, along with clearing registrations at both ends and repairing, with no luck. Is anyone else still seeing similar issues?
8.1 working fine with my Kenwood BT762HD. I use PowerAmp v2 alpha build 704 app.

Bluetooth issues

Hi. Wondering if anybody could help. When I connect my oneplus 5T to my car I have problems. When it starts to call it disconnects the bluetooth from the car completely. However the call continues on the phone which is a complete pain as you cant use it through the hands free. Car is a BMW 630CI with pro nav if that helps.
Many Thanks
i first had problems to connect to my audi A3 bluetooth ... it simply didnĀ“t find it
after trying again and changing the bluetooth audio codec it suddenly worked ...
Idk if it will work for you, but you can try changing the codec and se if it helps
Hi. Ive tried all 3. It connects fine and I can see my contacts but as soon as I hit dial it disconnects from the car.
Very strange.
Thanks for the suggestion tho
with mine in my car it every now and then gives me this a crackling sound.. Kind of irritating, I'm hoping a software update down the road fixes this.. I've tried all 3 codecs
Having issues with Bluetooth connection on my Prius Prime as well. It always disconnects, I had to disable Bluetooth on the phone and re-able it for it to work.
I experience the same with my Boss QC35. First connection, audio breaks with lots of noise and had to disable it and re-enable it.
Still found no solution. Hope the next update sorts it out as the bluetooth seems a mess.
So after looking around, there are issues with certain codecs and devices connecting being posted in the OP community forums. My Sony WH1000xm2 headphones stutter when using AptX HD. My JBL Everest 750NC's - if you turn the volume up too high, they disconnect from the phone. In my Cadillac ATS, whenever you place a call it'll stay connected, but you won't hear anything, and the other user can't hear you either.
I think they've acknowledged the issues and are working on them, but after putting Oreo on my Moto G5 Plus and Oreo's ability to change between all codec's on the fly (including native LDAC support!) I'm anxiously awaiting Oreo to be 'officially' released.
I'd say just be patient.. I'm sticking with this phone because I think it'll be worth it in the end. Wish I had better news!
so I resolved my Bluetooth issues by flashing FreedomOS. Now there is no intermittent crackling sound now and there is no issues at all ymmv, this was just my experience.
Thanks. Will wait for Oreo and then try different roms if it continues.
on FreedomOS before, it was giving me headache re-connecting to my Subaru car bluetooth, like after you shutoff engine, go somewhere and come back, unless you manually force connecting to the car, it barely auto reconnect back.
And also takes so long to get data sync from my Fitbit chargeHR to the app.
I don't think this kind of bluetooth issue related to what rom we have but the kernel and more specifically BT firmware.
-----edit-------
My friend also got BT issue when he tried to connect to BT headset. Hope Oneplus get something fixed on new oreo or updates
Just an update. Since upgrading to the official Oreo rom my problems have disappeared and my phone now works fine with the car Bluetooth.
Chris
I still have problems. Pause and unpause, and the track restarts. After ending a phone call the track restarts. 2018 RAM, Uconnect
With stock ROM 4.7.2 bluetooth connected only for a few seconds with my Audi A6. With every following stock ROM version it didn't even connect.
I tried every single Audio-Codec and the different settings in developer options - nothing helped. Once I cleared data & cache from the bluetooth system apps followed with a soft brick
Hi all,
Had same issues with my Hyundai ix35 and oneplus 5t (Nougat), tracks skipping, distorted audio in calls, etc... Tried emptying bluetooth cache, switching audio codecs without success. Now I just received the OTA update to Oreo (8.0), Oxygen rom 5.0.3 and it solved the issues!!! Yeay, no more auxilary cable hanging around !

I started from scratch but the issue persists.
I am having the same issue in my car. It no longer displays track information and the connection is not very stable. I will try switching the codec and report back.
i don.t have any volume control from the phone basically when i connect it to my car stereo
i can control the volume for the first 4-5 clicks ... and then the slider moves but there is no difference in the volume
i have to turn the volume from the stereo almost to the max
whit my old samsung tablet works great ... i have maybe 50% more volume then with my phone
tried all codecs ...

Bluetooth problem after update to 8.0

So, somewhere in May I received the automatic update to Oreo 8.0. Hurray! Sadly though, that's when my bluetooth problems started:
It connects to my car, as normal. And I can make and receive calls, as always. But during the call my bluetooth connection with my car would just drop. If the person on the other end of the line is patient enough, I can just reconnect while driving and continue. But it will drop once each minute. It's very frustrating. This worked flawlessly before the update.
Funny thing is there are no issues at all when playing music of a portable speaker. I can even play spotify through my car's speakers without problems. The problem only presents itself during calls on the carkit. To make sure it's not the car, I tried some other phones. My wife's samsung, also with 8.0, worked perfectly. So does my daughters Iphone with IOS. My car is a Volvo C30 from 2012. It has built-in phone connectivity.
What I tried:
- Unpairing and pairing again.
- Hard reset. In combination with re-pairing.
- Using the developer options to use Bluetooth AVRCP 1.4. In combination with unpairing and re-pairing.
- Using the developer options to use Bluetooth AVRCP 1.5. In combination with unpairing and re-pairing.
- Disabling automatic bluetooth/wifi scanning in the location settings.
- It even went to the repair center for a different issue (unresponsive touch-screen) and the repair notes stated that they also installed the newest software. So I had hopes that this would resolve my carkit issue, but it didn't.
Do you guys know any more tricks for me to try?

			
				
I have an XA1 ultra with Oreo 8 as well (build 48.1.A.2.21) and I'm experiencing the same problems, but adding that mine disconnects also when streaming music. Other problem I'm experiencing after the Oreo update is that,when using my watch (LG G Watch R) paired with the phone, the sound streaming is just crap, with lots of jumps and bad audio quality. This is so frustrating that I'm seriously considering buying a new phone ( not from Sony, of course)

Bluetooth and Car Audio

Anyone else having issues with connecting the 7T to their car and getting audio going out of it? My OG Pixel didn't have a problem, but I have to toggle off/toggle on Bluetooth and then manually tap the car's bluetooth listing to get it to actually 'connect' the audio portion.
Rather annoying, considering I'm only in the car for a few minutes at a time, this either eats into the time entirely, or makes me sit in my car for a couple minutes before even driving to fiddle with the bluetooth settings.
Car has stock headunit, 2015 Evo X. Like I said, original Pixel XL had no issues, but this is annoying. I've tried changing bluetooth versions to no avail. I can see it connecting and dropping the bluetooth connection fairly frequently while staring at it and trying to 'get it going'. But once it connects, it stays there.
My bluetooth headphones (Some knock off cheap Chinese ones for $20) don't seem to have an issue.
My connection to my aftermarket stereo is fine. Just seems a little quieter than my last phone. Connecting is kind of slow too when I start my car but it is automatic.
I don't have any issues with connecting to all 3 cars (2014 Honda Accord, 2009 Pontiac G8 Gt and a 2018 Honda Fit) but I do agree that the volume seems a little lower than my previous phone (Galaxy S8).

Hmm. Weird. Is there anyway I can check for logs to find out what exactly is happening? I haven't rooted, just don't know if it's something I can naturally pull from Android as a whole.
I had the same issue, but when I made the phone discoverable and initiated bt from the car stereo it seemed to work.
I also set a custom pin , not the default 0000
My bluetooth is quiet, but its also static-y. I never had any issues with my G6 and now I get static clipping every 10 or so seconds. Its unbearable.

I'm not really having an issue pairing it, but it's just connecting after pairing is the problem.
I have changed the default pin. I can see it popping up and down the car stereo a few times in the bluetooth settings before it just gives up.
As for the other issues, I'm not having a problem at all with audio volume, nor popping/static when it finally does connect.
My volume is super low when connected to Android Auto and streaming music. Have to turn the radio up to max. However, I'm assuming that's an AA issue or Android issue, as it seems many others are having the same problem with different phones. Been thinking of adding an aftermarket amp to the car. Maybe I should pull the trigger. Lol

My OnePlus 7t connects fine and phone works for calls on 2014 cts. The sound comes out of phone can change song on head unit but I can't get audio to play through car. Anyone else get this?
Yeah music stutters with car player... Only calls work. Music works on headphones etc. I couldn't find solution, did network reset, cleared cache. Nothing works.
Seriously!
I've wasted at least two hours already trying all the recommended steps: from flicking icons on and off to a full phone reset.
Still no connection to my Suzuki S-cross car. Multiple previous phones have connected effortlessly.
Even the $50 temporary five year old borrowed phone could handle it.
Anyone got any other suggestions? Yes, tried the AVRCP setting change from 1.4 to 1.6. That didn't work either...

Yep most have lots of tedious steps that are different model to model and if not followed exactly will cause this problem on occasion..
In my case music starts to be scrambled after 10 minutes or so of listening. When I take the phone (so the watch pops up) or turn on the screen it immediately works fine again, but when being put aside and the screen turns off, the issue starts again ..
Also in the early days of my previous 5t I had the same issues but some fix was delivered together with oxygen os update. And now the same story again
I have a different issue with Bluetooth:
- OP7T connects to car Bluetooth fine
- I can make/answer calls
- Bluetooth media works fine
The problem is with Google Assistant & car audio:
- it was working as intended until the latest update - 10.0.15 - I was pressing the button on the steering wheel the google assistant was answering questions through the car bluetooth, no need to switch to bluetooth media.
- after the latest update, when I press the button on the steering wheel, Google assistant pops on the phone , starts to answer question, but cuts off after 5 seconds. the command still goes through and Assistant still runs, but does not come up on the car audio.
- it looks like the Assistant is not connecting to the car as a hands free, but as to a bluetooth handsets.
Anyone experiencing this?
