Hi. I have had a 8t 5g for about a month now. Just got a pair of bluetooth headphones (Sennheiser 4.50btnc) and when i go to pair them they dont show up. I have paired them w my PC and they work. When Im in my bluetooth audio codec settings I can see the aptX options and a few others listed but they are all greyed. Am i missing something?
Try clearing the system cache and a network reset.
Androids are notorious for hidden, I mean, advanced settings. Double check to make sure they are correct.
Try enabling Developer options as well for more settings.
I have dev settings on, that's how i was able to see all the codecs and settings I think. Clearing the "system cache"?

Google it for that device. It's either on the boot menu or in advanced settings.
Good to do if having issues or after installing or uninstalling apps, updates.

done. Cache wiped. Network reset. all options for codec still greyed out. I noticed also that the button for HD audio is turned off and greyed out as well.

Try SBC first, that should work with all bt audio devices. Try toggling the earbuds off/on.
Does the phone "see" them?
Will it work on calls?
Is there an app that comes with that bt device or one on that phone?

All codecs including SBC are greyed out, SBC, AAC, Qualcomm aptX +hd audio, adaptive X, aptX tws. "Use system selection" is on by default. Ive turned off the haedphones and back on several times. they show up immediatley on my PC's bluetooth, and work just fine just not on the 8t. frustrating.
so my phone works on the bluetooth in my car using SBC driver. The phone itself displays plenty of driver codecs in the bluetooth settings. The headphones in question (Sennheiser 4.50btnc) only work on my PC and not my phone but 2 other bluetooth earbud devices worked fine on my phone other than the crappy blutooth lag which is why I looked for headphones w aptX. Im inclined to think that because these headphones are "refubished" that this pair is just Janky. Need to return them.

Update their firmware... if possible.
Or return them if easier.
it's normal for these options to be greyed out. the system will always choose the best codec for you.

It means that for whatever reason(s) they not available. Could be a settings, software, firmware or a hardware issue or it's not designed to support the device.

You should verify with a different app that they're not being used. Even when they're not grayed out you still can't change them

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?
I've been experimenting with the Bluetooth options in developer options, but every time I change them, they change back to the default settings.
Has anyone any help on how to make them stick?

I've experienced this as well. I believe by design, you must first have an audio device paired and connected before changing these settings, and even then, when doing so, the BT device must be capable of such settings. As an example, when my BT headphones are connected, I can set the DEV option to a lower than 24 bits "per sample" but not higher. All the settings here depend on the hardware in use and whether it is capable of the setting. ->Then when disconnected, the dev options return to their default settings. -But they should return when re-connected.
-hope this helps to at least get the discussion ball rolling.

^ The above is definitely not true. At least not for everyone. I have a galaxy note 9 and I've tried connecting headphones as well as a pair of edifier speakers. Nothing except AVRCP version sticks, and that sticks whether I have a bluetooth device connected or not. Everything else does not stick, even though both devices are of course capable of aptX and 48khz and 24b/s. In fact the speakers are intended for 48khz 24b/s, it causes audio stuttering if I have anything else. No matter what I do, everything just defaults to SBC, 44.1khz, 16b/s. It's clearly broken and has been for like 3 versions of android OS lol. Every android phone I've ever had has had this problem too. So clearly it has nothing to do with the hardware you're connected to, since all the devices I've connected are intended for aptX, 48khz, 24b/s. And I don't think it has anything to do with the phone's hardware either, since I used to use an essential phone which is advertised as being intended for aptX HD use with the "TIDAL" app. They gave me a 3 month free trial to this service and said it output high fidelity audio via aptX HD. But no, the essential phone's bluetooth developer options behaved in exactly the same way. I've tried a lot of other things as well, so I'm pretty sure this UI element is either just fundamentally broken, or is intentionally locked from the user, presumably for some patronizing reason
Anyone have issues with low volume with android auto. My 3 XL works fine, proper volume etc....But with my 3a whenever I try and play music the volume is very low. I have to turn the head unit volume all the way up to even hear it.
I tried a different cable, resetting car and phone. etc
If yours is good are you on Pie?
Thanks
Direct connection or via Bluetooth?
If Bluetooth, there is a setting in the developer settings called "Disable absolute volume". Click that and it may fix your Bluetooth volume issues.

Reinstalled pie.... volume is fine..... anyone on Q beta 5 have good direct connection sound in Android Auto?

Reported. Still an issue on DP6.
Edit: please star it if you experience the issue as well.
I have a Pixel 2 XL and have the exact same issue. Started having the issues in DP5 and it's continuing into DP6. I also just got my phone replaced yesterday by Google for a screen burn, so the first thing I did was update to Q and check to see if it was maybe the old phone, but nope, even with a straight from factory phone with new install of Q it's no different.

Found a Reddit article with a work around for this issue. It worked for me so maybe it will work for you! In developer settings change the below Bluetooth setting to 1.6 and reboot phone and try again.

Odd a Bluetooth setting fixes USB audio routing. Audio through BT is fine in the car, only when routing through USB it is low. Will try next time I drive my in-law's car.

I agree it is odd. However after thinking about it a little when using android auto it requires your phone to be connected via bluetooth at the same time. Even if you un-pair your phone and turn off your bluetooth android auto turns bluetooth back on and pairs your phone to your car.(Atleast with mine that is)
But I have been having success since Friday now after making that change so hopefully it helps you out as well!
I saw the suggestion of that during DP5 and tried that and there was very little difference for me switching to 1.6
I was thinking of buying this phone, until I realized it "presumably" doesn't support the LDAC audio codec [Info from bluetoothcheck.com]. I want to know from an actual user, is this true? Because, I saw on YouTube, that for someone else it actually did work.
Any answers will be appreciated!
Why would you buy this phone to use with wireless earphones?

Well, mostly I would use the headphone jack, but, occasionally, at the gym or while running, it's more convenient to use bluetooth earbuds (And, I don't mean some kind of a mid tier ones, I would be using 1MORE ANC Pro EHD9001BA)

I have also tried the the DTS:X feature on my LG V35, but for me, particularly, on wide instrumental or detailed (heavy metal, etc.) genre songs, it interferes too much with the sound equalization. Therefore, I like to keep it flat and original, but I understand the appeal/it's a personal preference.:good:

Information for people who have LDAC headphones and cannot turn on this mode, and in Developer Options they have "Bluetooth Audio LDAC Codec: Playback Quality" greyed out
Applies to Android 11
You have to go to Settings-> Connected devices-> Bluetooth-> select the device - enter its settings (gear on the right) -> Connection type and change from Most stable on Best sound quality.
From now on, if the device supports - you can choose LDAC or AptX HD, which are inactive by default, because the phone pairs devices by default in "Most stable" mode.

Hello, I have the same problem on another device. For some reason, the "connection type" option accessed by clicking the gear isn't available on all devices.
I managed to make it show up on the WH-1000XM3, but I don't know how, and know that I'm using another similar device (Fiio UTWS5 for the curious), I'm stumped as to HOW access this option.
I did however, successfully forced aptX (not HD though) codec through developer options, but that's it.
May you help a noob?
Thanks!
Strange Question.
OFC yes!
Any way to enable all of the bt codecs that are supported by the processor but disabled by samsung?
Can only select SBC.
Bt device needs to support the codec.
Some apps use only sbc.
If the app and device use the blanked out codec try clearing system cache, a network reset, turning Developer options off then back on.
Make sure you didn't disable a needed service, turn off global power management.
The problem is Samsung disabled the high res codecs. Even with a supported device, it can not be selected.
LDAC and SCC should be available.
No APTX HD.
I got ldac working. Thanks

"When you connect a bluetooth device, this will automatically switch"
Welcome to XDA
English only please per forum rules.
Best to check it in Developer options when connected and using to verify the codec in use if set to automatic detection.
Samsung also hides a toggle in Settings - Connections - Bluetooth - your Bluetooth device. This is how I got LDAC working on my Soundcore Liberty 3 headphones.
