Telephone cant find bluetooth-headset!

Hi! I have a brand new Jabra 620s bluetooth-headset. When I turn the headset on and search for bluetooth devices on my computer I can see it, but I cant see it when I search for it on my touch pro.
What could be the problem here?

I had a similar problem last night (and have it quite often when i need to pair). It doesn't detect it until the 3rd or 4th time in which last night it didn't even detect it either. I power cycled the headset and my phone found it the first time.

Yeah, I tried rebooting my headset and my phone several times, but I still can't get it to work...

Figured it out... Had to hold in a button on the headsett to make it avaliable for new devices...
But new problem:
I don't get sound in the headsett when I play music. But when I make a call the sound is in the headsett. What could be the problem here?

Maybe its the settings in your a2dp profile?
I read this "Set-up of the 620's was simple enough, the headset unit is paired with the device that is streaming the music and / or a mobile phone. A smart move from Jabra allows the 620s to be connected to both a mobile phone and an audio device simultaneously. However our set-up was rather more straight forward than most as we used Jabra's own Bluetooth dongle that supports the all important A2DP (Advanced Audio Distribution Profile) profile. Real life for most users is a different kettle of fish with support for A2DP being quite sparse, most music gateways and servers and even music ready mobiles rarely support the required profile." source: http://www.lordpercy.com/jabra_bt620s_review.htm
Maybe some tweaking in hklm\\software\microsoft\bluetooth\a2dp\Settings
I believe this headset also supports AVRCP profile. In any case, make note of your original configuration prior to making any changes.

You can use Advanced Config to enlarge the bluetooth bitpool under the bluetooth tweaks. Set it to "very high" for best sound quality (uses more system resources tough).
HTH

Maximum bit-pool setting is 1561. I dont think it solves the problem, cause the quality is still really bad.

Any other tips? Or do I have to return the headset cause a brand new ~1000$ phone cant play on a wireless bluetooth headset?!

Bump.. Are there really no solutions?

Bluetooth issue in car

Whenever I connect my phone by Bluetooth to my car's stereo, only the front speakers work, nothing from the 2 rear speakers. I've tried adjusting the fade and checking settings in poweramp but still nothing. I'm not sure if this would be an issue with my phone, the ROM, or the car audio system. I'm thinking it's an issue with the car's audio but I figured I'd ask here in case somebody else has had the same issue. I am on liquid smooth 3.0 April 24th build with elemental x kernel but I had the same issue with my galaxy s4

I have no problem with nexus 5 and my car Bluetooth connectivity.
Make sure that your audio system, GPS and make and model are compatible with the bluetooth from the phone. Some other connectivity issues are that the car kit cannot decode the Bluetooth device that it is trying to connect. This decode means that the system cannot recognize the name. This is a frequent problem when devices have been upgraded. While your system may have worked fine before, upgrades can cause problems because the compatibility all of a sudden changes. This is an issue that has not really been addressed by the manufacturers.
Another frequent problem that can occur is that the Bluetooth will connect but then it will not stay connected and only one speaker is running,. Many times this can be a hardware issue.
So the bluetooth device can connect but it does not work properly. In this case there is an issue with the stereo connection to the Bluetooth unit. There is nothing actually wrong with the bluetooth or devices but this is a software issue. To fix it see if the manufacturer is offering any updates. If one person has had the issue then you can bet that many people will have the problem. This is a problem with the car kit software as no matter which phone or earpiece you use the audio will not play from the speakers. Check that the vehicle supports bluetooth audio as some only will support bluetooth phone calls. These are 2 very different things.
Most of the time, look into the settings for the bluetooth and the car system. If the car battery should die then the system may reset to the defaults. This means that all of the current settings will be lost and need to be reset. Not only will you need to check the settings in the car system but also in your phone or other bluetooth device. In order to correct the bluetooth settings the device will need to be connected to the computer.

I have an aftermarket Kenwood double DIN deck with Bluetooth 2.1. It connects perfectly fine, shows up with Nexus 5 when pairing, shows the song title, shows the name of the person calling... It works great when plugged in through the aux port, but of course doesn't show me any information that way. When I had the S4 it showed up as SGH-M919. It stays connected just fine and I had it playing for a while before I tried turning up the volume and noticed it didn't sound right and figured out the rear speakers weren't playing.
I just checked and noticed there is a somewhat recent update on Kenwood's site but it was still about 3 weeks before I bought the deck... I'll try doing that though. (edit) just checked again and the update isn't for my model, there's no software for it
Thank you for answering since I'm pretty sure now that it's a problem with the stereo and nothing to do with Android lol
Kind of embarrassed to admit it but...I did have Car Toys install it so... they probably didn't do a very great job. I knew I should have had either Best Buy do it or tracked down a friend that could do it. Oh well

HTC U11 Bluetooth Audio Quality Issue on Android 8.0

Hi, last week I installed the OTA Android 8.0 update on my HTC U11.
Since this update the audio quality when streaming to my car's audio system or to my pioneer hi-fi system at home is a lot worse than on Android Nougat. Especially on tracks with a lot of high tunes. There's always a slight 'clink' noise. I don't know how to explain this in English..
Have you noticed this issue as well? Is there something I can do about it? Thanks

question are you using any sound mods?

Same for me. Since this update, the quality of phone call when connected to Bluetooth to my car is really bad. No problem with music stream connected to the same car.
I tried managing the new bluetooth options in developper mode menu but it doesn't solve the problem.
The codec used is all the time SBC even is I change it to AAC or aptX or AptxHD.

I have the same issue, it seems it was fixed in 42 version for US market(at least for LDAC)

I have 2 issues with Bluetooth connections with the car. The first is that it picks up interference from the noise of the wheels and engine while driving, and the sound quality suffers and it sounds unclear, unless I mute the vehicle.
The second is that it has a lot of trouble connecting to the car at times. Or, more often, it would not connect the media through the car. Don't know what's up with that.

I know how you feel
I've got exact same problem like yours. Although I'm using HTC u11 plus. My new pair of Bluetooth headphones have the same not OK audio quality. You're right especially the high tunes. I'm desperate, trying to reset everything, but doesn't help. If you find the solution, please let me know. Thank you.

Same issue here. I have the U11 as well and just updated to Oreo and I have the same issue as well. Music over BT was ok on Nougat but after the update, music sounds as if there is digital clipping. And it's there with both my headset and car audio system.

Got the same issue, hope they fix it soon. The only solution seems to do a RUU right now.
Btw. I am on a custom rom (LeeDroid), gonna go full stock and try again.

I would suggest looking in developer options and trying some of the different options for bluetooth in there!
Settings > about > software information > more > then tap the build number till it says you are a developer.
Then
Go to developer options and check under networking, there are some settings to toggle in there.
You may find something you are looking for! I personally haven't tried bt since the update so I don't know if it is a common issue. Good luck!

Thank you!
Thank you very much.
Playing around with the bluetooth options in the developer's menu solved this issue.
The audio quality through bluetooth is now pretty much the same as it was with the previous android os

Share what settings you stuck with so it may help the other people with the same problem

Hey there!
Same problem for me since updating my U11 to Oreo - very poor bluetooth audio quality...
I tried using different bluetooth settings under the developer options but the thing is: no matter what I choose, it keeps switching back to the default values not affecting anything at all.

If it switch back to default SBC it means your headset/BT device doesn't support other codec.

That's not necessarily true. On 7.1 both Bluetooth devices which I use can support either AAC, SBC and aptX. My understanding is this issue occured because of the removal of AVRCP 1.3. I think Google added 1.3 back to Android 8.q because of this.

Yours is not necessarily true either. I'm on 8.0 and I can still use aptX if I want but only if my BT device supports aptX.

I'm not arguing that aptX and other codecs aren't working on 8.0. What I'm saying is that with certain devices, we are no longer seem to be able to use certain codecs that we could use prior. It's obviously device dependent, but to say their isn't a problem and blame it on the Bluetooth device is incorrect. Infact the same problem has occurred on non HTC devices when they've upgraded to 8.0 such as the OnePlus.

Fair enough, I didn't understand.

Does anyone know how to make the bluetooth options under developer options stick? I'm on stock unlocked Oreo, and they go back to defaults as soon as I change them. I've tried changing them whilst connected in the car, but no change. The only thing that could make a difference is that I'm running Pitch Black Substratum theme. Anyone else got them to stick?

In my Audi a3 2015 before oreo i can able to skip the track with entertainment commad and in the display i saw name of the track. After update i have lost all funtionality and the car see my device only like esternal suorce . Can i do something?

No support for higher bitrate on LDAC?

Been using the Pixel 3 as my daily driver for a while now, but just recently came an interesting piece. Apparently, the Pixel 3 doesn't support LDAC at Optimum Audio Quality (more details here - https://themrphone.com/article/google-pixel-3-xl-doesnt-support-ldac-at-optimum-audio-quality/)
I was planning on buying a high-end set of Bluetooth headphones, in fact, was considering the same ones used in the link above. Can anyone else confirm this?

Working fine for me with both LDAC (detected and used automatically) and "Optimised For Audio Quality" (switched from default "Best Effort" in Developer Settings)
Pixel 3 (non XL) with Sony MDR-1000X (gen 1 of the headphones in your linked article) and Google Play Music.
Granted GPM isn't a Hi-Res source, but it's playing fine! There was a momentary drop in audio for a split second on changing bit rate but it resumes with no issue!

I had this same issue with my Audeze Mobius--the Pixel 2 allowed me to set the rate to 990, but the Pixel 3 would do as described in the link. Seems like a software bug, I doubt it actually isn't capable of using the full rate

I can't say, I'm much of an audiophile or anything but I do like to play with settings for what sounds best with what I have. On my Galaxy s8 running oreo and my previous s5 running aospx/oreo I could change the developer Bluetooth settings on the fly and notice the difference instantly (avrcp/bt_codec/sample_rate/bit_rate/ldac_codec).
If I do it on the pixel 3, the Bluetooth just falls out, connection wise it stops but still shows it's connected, app wise I can't close and reload the app. I have to turn the Bluetooth off or reset it completely sometimes.
It's kind of a bummer, being a brand new phone and all, I noticed the absolute volume disable didn't seem like a difference either.
I hope they resolve it.

Update: disabling bluetooth a2dp hardware offload let me freely change all those settings while in use with out locking anything up. What that necessarily does or the effect of changing the settings and how well they actually change??? I can't answer with any rational or testworthy explanation as my audio products are oem Bluetooth radios in vehicles.

Question Bluetooth interference in public places when other BT devices are around

Hi everyone,
I have paired my OP 9 with my Cambridge Audio Melomania Touch Bluetooth earphones as soon as I got the phone, about eight months ago.
The phone has received several updates and upgrades in the meantime, but an issue has surfaced recently, as the title indicates: when I'm in a public place and there are other BT devices around, the music playing from the phone into my earphones suffers interruptions and distorsions, as if the phone was trying to pair with those devices, or maybe the Melomania Touch, I don't know.
I'd tend to think it's the phone, because I've had those earphones for about two years now, and with my previous phones (Xiaomi/Poco, Samsung), I never had such an issue. Once paired, the devices would deliver a solid, steady sound, with the occasional hiccup if the phone was in my pant pocket and I turned my head in the opposite direction, but that was it.
With the OP 9, however, every time I'm on the bus or the tram, or even waiting at the bus stop and a car passes by, I hear an interruption in sound delivery and I know the car in question had BT enabled.
In the Bluetooth settings, I've unchecked the option to make my phone visible by other devices, and in the Developer options, I've limited the number of devices the phone should try to connect to to 2, the Melomania Touch (it used to be 3, the third device being a Sony WH-700 BT headset I have at home, but I cleared it from the list).
I don't see any other settings to play with to make this inconvenience go away, and the Melomania Touch app doesn't offer any option either. The earphones are set to deliver max performance (not Low Energy BT).
I'm counting on you guys on this one!

Hi and thanks for taking the time!
Yes, HD Audio is enabled, though I found it in the Developer options. BT options are pretty basic on this phone, if you ask me, but sound quality is really good, especially with those earphones.
