Bluetooth display of songinfo @ car problem - OnePlus 5T Questions & Answers

My car (Seat Leon 5F with Media System Plus) suddenly displays no more song info and the progressbar is f***ed. I hoped Oreo would change it, but it doesn't.
However other phones combined with my car work and my phone works in other cars. I already tried resetting the Media System. It seems it has something to do with the AVRCP version.
Any ideas?

I have got the same problem (no song info on my car's media display) after upgrading to Oreo (it was fine on Nougat).
Modifying Bluetooth codec/AVCR version in developer options didn't help.

did a full wipe and installed 5.0.3 from scratch, it's working now

A full wipe also restored music meta-data, however music controls (track skip/repeat) from the steering wheel do not work. Worked fine on Nougat.

I don't want to do a full wipe.
I tried unpairing and pairing with my car again - didn't help (still no song info).
Does anyone know what files should I delete to reset Bluetooth settings without a full wipe (I'm rooted, so can access/delete any file)?

They don't work for Bluetooth headphones and they don't even work for wired headphones FYI

I have found a solution that works for me:
1. Set Google Play Music as the default music player in the settings.
2. Reboot.
3. Problem solved.
Weird stuff...

[Q] Bluetooth saved profile

I have installed the GingerSnap v1.21 on my SGS2 T989 phone.
Maybe something wasn't cleared before I installed this ROM because I am having very little battery life 8 hours with very little use.
I have paired the phone with my car through bluetooth and phone + media player works perfectly fine.
I need to get that settings from my phone (the pair information as well as the bluetooth profile etc).
When I re-flash the same ROM with
-factory reset
-cach cleared
-wipe delvik
and re-install the ROM the battery life is amazing but I am unable to stream the audio to my car bluetooth.
It paired fine but no sound. I tried so many different option but no luck, no error when I pair, phone says connected with phone and audio. car bluetooth also shows connected/paired successfully, the phone works fine on car stereo as well, but no streaming ....
My only luck now is to somehow save all the related bluetooth profile/information files and overwrite it to the new flashed rom.
Can someone suggest something please?

[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:

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?

Problem with car stereo after lollipop update

Hello everyone,
I have just updated my At&t Galaxy note 4 to lollipop a couple of weeks ago and I have lost the ability to skip tracks from my Pioneer DEH-P8400BH car stereo, while connected through Bluetooth to my note 4. I have tried with the stock music player and Playerpro and nothing happens when I skip a track back or forward. I don’t have any lock screen software and I have a Gear 2 always connected to my phone that can skip tracks without issues.
Please I need some help, it’s very annoying and not to mention dangerous to deal with my phone while I am driving.
Thanks,
I use google music and I have never had that problem. I use my steering wheel controls and can skip tracks without a problem. If you created that Bluetooth connection before the LP update, I would unpair the devices and re-pair them. If that doesn't work, consider a factory reset if you haven't already. Many people fixed lots of problems after the update by doing a factory reset.
This is a new LP Bluetooth music issue that I've never heard of. Just a suggestion:
If your Pioneer has updatable firmware (if it's aftermarket, it might. You didn't specify whether it was stock or aftermarket), then make sure it's updated. Otherwise report the problem to Pioneer.
Sent from my SAMSUNG-SM-N910A using Tapatalk
It's probably a Pioneer firmware issue. I have two cars, one has an AVIC X930bt in it and the other is a Lexus with factory stereo. On the Lexus, everything has been smooth sailing but on the t-bird with the Pioneer after market, I noticed it no longer works to change spotify songs using the head unit as I could before.
I also have the issue with my Pioneer stereo in my car...
I have updated my car stereo and that fixed my problem.
Thanks for the tip.

Question Bluetooth Media Playback in Car via Bluetooth Stopped Working with P6P

My P6P (US Unlocked) no longer plays media via bluetooth in my car. It just decided to stop suddently (while playing). Calls are still fine.
Things I tried:
- Bluetooth On/Off (On the car and on the phone)
- Unpairing/Pairing
- Reset Network Preferences on the phone
- Tried another phone with the car (works fine)
- Enabled/Disabled the bluetooth media profile (kept the calls and contacts sharing)
- Paired other bluetooth speakers to the phone and they work fine.
The phone seems to think that audio is playing and so is the car, it's just silent. I'm on the December update.
Any thoughts?
Are you by chance having this problem with SOUNDCLOUD? It's been trouble since my Pixel 2 & 3XL / Android 11. And I can get it started with force stop + clear cache, but it is a pain!

I've had a similar issue since getting the P6P. Usually it's (randomly) when I try to skip/restart a song or when the song ends the phone will still think it's playing, but the display for the car will show it's paused so audio will stop. To get it playing again I have to turn the phone screen on and press pause then play and it'll start playing normally. As you mentioned, only an issue in the car. No issues with any other bluetooth devices.
I haven't been able to get to the bottom of it, but I updated to the December build last night hoping that might fix the issue. Haven't been anywhere yet today to see if it worked, but your post is giving me doubts now lol.
Edit: Just to add, this is playing music locally from storage with the Retro Music app.
Since the December update i have the same problem, it will connect to phone but will disconnect and not reconnect to play media
On the December update. Was in the car today playing all my media. Iike Spotify and local music and works like a charm. Sounds awesome in my Mazda 3 through Bluetooth. Also same call signal as before more or less. Right now at least is good....but haven't left my area as it's the weekend. LOVE MY P6P!
More things I tried:
- In Developer Settings, changed Bluetooth AVRCP to version 1.3, 1.4 and 1.6.
- In Developed Settings, disabled hardware A2DP.
Still no dice, maybe I should go for a factory reset? Man this phone is weird
Yeah my bluetooth headphones and my home theater amp do not skip a beat, but my car keeps cutting out the music, only just started happening, slightly after decmeber update, so I think they pushed other updates (playstore) which caused these issues. Rebooting the phone fixed it, but nothing else including mentioned in the OP repairing the phone to the car, seemed to make it slightly better.
I too have also noticed the similar issue where the music just stops for no reason, and the phone app thinks its still playing, phone reports it's still connected.
For the OP, if you rock the volume keys up down and up again does it change, beause I did have mine at some point force to zero volume.
Update, it scould be related to temperature because in the morning do not seem to have the same problem, only in the afternoon, temp about 30deg C

I tried to rock the volume buttons on both the car and the phone and it doesn't seem to change anything. Both the car and the phone actually think that music is playing (as if it was on mute) and the progress time is always in sync.

Nope, It was actually fixed after factory reseting the car's headunit. Weird but at least it's all good now....

Hi mate, i had same issue, installing android 12L beta 3 fix all my problems, battery is awesome, fingerprint fast, animations smooth like butter....give it a chance and try, maybe fix all your problems.
I know it's a long shot but you should check the settings for automatic do not disturb. I had that happen when the phone realized I was driving and it drove me nuts. Uncheck and mystery solved.
Now if someone can tell me why at completely random times and within a call the device switches back to phone speaker or watch Bluetooth while on an Android auto phone call I'd be appreciative.

Try disabling a2dp hardware offload in the developer settings, fixed all my bluetooth issues.

Question Audio not routing to Bluetooth earbuds

Anyone having issues with audio not routing to Bluetooth earbuds? Only fix for me so far is to reboot the phone. But the issues comes back later or the next day.
It's strange too, I'll have issue with the galaxy buds pro not working for audio or phone calls but I switch to the Sony XM4 and it works for audio but not for calls. Reboot and both works again. I've tried unpairing and resetting Bluetooth and also the earbuds but nothing works except reboot of phone.
Network reset and try clearing the system cache.
Try swiping down once then hit media output and selecting the Bluetooth device there
not sure if these will help as well but these were the solutions i have done when i had bt issues. these are not in order by the way, but alternative solutions
1) clear the bt cache. unpair then pair again
2) i installed bluetooth audio widget
3) i once bought a jam loud buds from jb hi fi. it would drop out or it wouldn't connect at all to my fold. turns out it was still paired to my old samsung note 9. had to delete that pairing and it finally worked with the fold. didn't know some devices only paired with a phone once
4) bt version. i had an old bt remote used by my daughter. it paired with the fold but did not work. did some reading and the bt version of the remote could be the cause
5) above posts from blackhawk and sonin66

Buds+ software and firmware* have given me a lot of trouble. A real pain. I'm running two N10+ N975U/N975U1's one on Pie the latter on 10.
These are the apps I load but they may not work on 11 or higher, don't know... In any case uninstalling then reinstalling may fix your issue if the network reset fails too. Firewall block "Apps (UID)10343" and Wearables Installation Manager. Keep them blocked or they will update... and you'll be repeating the process.
For all these apps they must have all their permissions enabled to open!!!
*if you have a pair of Buds+ do not upgrade their firmware! It trashed the sound in my one pair. Now they need reflashed...

done this, and the correct device was selected but no audio. Sometimes music audio works fine but not calls
Idk if this happens for you guys but I went to a sony showroom today and when I paired my mobiles with some soundbar units like sony HT-S40R, HT-G700 and HT-S500F and some other models soundbar all of them got this weird issue, we can hear the music but every 2 or 3 sec it feels like it stops and then resume ( on the music player app it's working normally) I though maybe because of my spotify app I tried Youtube, youtube music amd amp all of them gives the same weird results ... This was before rooting my phone ... Ofc after rooting it it's stil the same issue (Android 12 and 13) hopefully this happened with those specefics models and not with my earphones or headphones bluetooth
Also note my S21 ultra works perfectly with the models said above
