No APTX !?

Hello,
I just noticied that it seems that Mi Mix 2 doesn't support APTX HD, with my bluetooth headphone and his apps, when i switch to APTX HD, the music cuts every seconds... Whereas no issue when it's on SBC...
Just, WTF?! how it is possible that a supposed flagship don't even has APTX? no headphone jack and no APTX?! are they joking?
It's possible to add the APTX HD codec to our device?

Android P Beta DP 4: Bluetooth Latency

Has anyone noticed any latency with Bluetooth headphones on DP4? I was on Oreo and previous DP3 and had no issues with my truly wireless headphones. Using Sol Republic Amps Air and Samsung IconX 2018 and they both now have Bluetooth latency with video, was not like that before. I tried changing the codec in dev ops, but for some reason, it keeps reverting to the same codec. Possibly an issue with the headphones not supporting every codec. But my challenge is this was not an issue before.
Looking to see if anyone is reporting similar issues or if I need to do some more internal investigation on my hardware.

Very strange that headphones that worked without latency, now have it with the latest DP. With my Bluetooth headphones and car system (which have never had latency) I haven't gained any issues with any of the DPs.

I am using it and it's fine. Music gets transmitted digitally via bluetooth, so either your car bt adapter is old or broken. I am using different bt devices with sbc and apt-x and all work fine. Xiaomi.eu weekly rom

so maybe my device have some bug, because when i connect honor 10 or galaxy s9 sound is rich and clear...
i am using lastest xiaomi.eu stable rom and car is Fiat 500X with built-in nav...

Bluetooth audio quality question

Hello. I change phones alot and have noticed that some phones(all android) have better bluetooth playback than others.
I had a oneplus 7 pro before this phone and the bluetooth quality to my truck was great and had no issues but with this phone the highs sounds scratchy or like if the speaker is bad. But if i connect it with a wire connection it sounds great. Everything with the 2 phones is the same. On both i was using the galaxy watch and pretty much the same apps. On a previous phone the note 8 i had the same issue but it was a different car. Seems like its the way samsung handles bluetooth.
Has anyone had this issue? If so was there a fix?
Thanks

What do you mean?

The only two things I think about is the codec used that may be different across devices, and the Bluetooth settings that sync the phones volume with the headset (the differences are noticeable).
Since no DAC is used in Bluetooth, I don't think it can comes from them, for a same headset.

On Samsung phones you should run the adapt sound process. Try this.

I tried with the sync volume off too and no improvement.
I looked for the adapt sound and my phone doesn't have that setting. Or is it something different?

It's in Sounds and Vibration 》 Advanced Sound settings 》Sound Quality and effects 》 Adapt sound
You have to do this in a quiet place and ensure to answer honestly. If you can't hear the beeping press no.
After doing this the sound quality is night and day difference.

Ok found it. Ill play with it a bit. Thanks

I've had issues sometimes with audio being piped through the "Calls" Bluetooth channel versus the "Audio" channel so worth checking as the quality is obviously night and day.
I also like enabling Dolby Atmos on my Note 10+ for music so worth playing with too. Additionally, I recently found Samsung's Sound Assistant app which let's you customize a bunch of sound settings so worth checking out as well:

Is there an easy way to tell if the audio is going through the call channel?

Easiest is probably just uncheck calls in your phones BT settings for your truck (and make sure audio is enabled). If the sound is still not great then this isn't the issue.

Sorry to respond to an old thread, but I was wondering if any of this fixed the OP's problem. I followed all the recommendations here and on other threads but have not been able to solve my recent Bluetooth audio problem. The sound has been terrible lately.

Same issue here on my s10+. When playing any audio in my car via BT i hear the distortion/hissing noise especially when the song has a higher treble frequency.
I have just about tried all fixes i could find on Google, and no luck.
When connecting to my ear buds (Jabra Elite 65t) it disappears and checked in developer mode that it supports to AAC for BT Codecs.
But when connecting to the car it reverts to SBC.
The issue clearly lies on Samsungs side, as my brother has a Huawei p30 Pro, also has bluetooth 5 and plays amazingly well in all aspects (Bass-Mids-Treble).
I know I'm posting this almost a year later, but i am desperately looking for a fix.
SN. I have recently updated my phone to Android 10, despite all the complaints to Samsung from many users... Sadly this issue has not being fixed on my side.
From what i see online, people have given up on Samsung and opted for Rooting their Samsungs and installing Viper4Andriod.
Has any one done this and can confirm that it fixed the issue?

Bluetooth CRACKING/POPPING noises!

Hello everyone.
Since 2 months I know have this "strange" phenomenon that when I connect my Realme 6 Pro to my Bluetooth sound device of my choice, for the first few times connecting there are only popping/cracking noise sounds coming out. No music or anything relatable. After connecting around 5-10 times, it finally will play music (also it suddenly goes back to the cracking state when clicking around in youtube).
Bonus: most of the time (even if connected right and playing music) the microphone wont work in calls.
I cant fix this sh*t and it really bothers me a lot lately.
Hopefully someone can help, or else I´m going to throw this phone into the trash can... xD
Greetings.

My BT works fine for the most part, but sometimes it breaks up. I am really hoping it's just a software issue

Me too, for about 2 or 3 months now. Wasn't a problem before. Thinking I'll try factory reset soon, see if that fixes it.

Hey! I also have this problem and what i found is, if your Bluetooth audio support Aptx codec, it will enable option "Use High Quality Audio" in your audio bluetooth settings. Try to disable (it will use SBC Codec) and my problem disappear.
But, it really annoying. I already try my bluetooth audio with another phone and it worked fine with Aptx, so i know my bluetooth audio is not my problem. My workaround so far are disable high quality audio, then enable Aptx manually in developer options with AVCRP 1.6
Not sure if my device actually using SBC codec or Aptx after change it manually on developer options

Hi All! I solved problems with Bluetooth by switch off Dolby Atmos!
