AptX is a newer streaming codec for better quality.

Question for people with Oreo Beta regarding aptX

Hi, I'm thinking about getting the Mate 9 and see that the Oreo release is supposed to happen soon.
Has anyone with the Beta been able to test if you can enable aptX for your Bluetooth headphones? Does pairing under aptX or aptX Hd work?
Thanks!

Yes, it seems to me aptx and aac works in this beta. I can't show you hci log, cause phone does not create HCI log. But phone shows *streaming aptx* when i listen to the music with my beyerdynamic byron bta. You can even choose discretisation 44'1 and 48 khz. You can choose aptx, sbc, aac. AptxHd and Ldac doesnt work, despite of these are in the list too. I will not lie to you, that i hear great difference, but i definitely notice video/audio sync is much better with aptx, then sbc. So i made a decision it really works!

Let me get this straight, no Jack yet the BT codec doesn't stick??

Always reverts to APX. When I select APXHD or Sonys ldac it reverts back to regular APX after song change
Awesome glad I can use my nice BT headset to full effect, NOT!
Is oneplus aware and how do I make them software better BT options??

It's "aptx" not "apx"
What's headphones are you using? Name them
Where are u changing codec, in developer options?
Both the headphones and the device needs to support the codec. If the phone is switch back to aptx, then that means that the headphones have only support for aptx and can't use other codecs like ldac.

There aren't many BT headsets that are aptxHD compatible, especially so if you've had your headset for over a year. They will revert back to the highest compatibility of the headset you're using. I bought My Sony MDR-XB650BT headset just about a year ago and they are only aptx not aptxHD capable.

Ya'll are right, ty

LG G7 cannot be switched to LDAC as its Bluetooth Codec

I bought an older LG G7 as my mobile music player (It is on Android 10). As I have two decent Bluetooth headphones from Sony and Shure I tried of course to pair these with LDAC. But so far this did not work, the G7 always falls back to AAC. This gets confirmation from both the Sony and the Shure app on the phone.
But both headphones can connect with LDAC as a Bluetooth codec with my tablet, a Lenovo Tab P11 Pro.
What went wrong and what could I do to get LDAC on the G7 too?

This was the solution: The changes have to be made not only in the developer options but in the Bluetooth menu too:
In the Bluetooth menu I clicked the options of the connected headphone then clicked connectivity and then best sound quality. Now I can use LDAC on all my tested devices: LG G5 and G7, Samsung Tab S6 and Huawei Mate 10 with both Shure Aonic 50 and Sony WH-H900N.

Bluetooth Headphones and AptX

Can someone help me understand AptX and audio latency? I bought a pair of BT headphones to game with on the 8T. I originally thought BT 5.x was supposed to help with audio latency, but it does not. From what I was told, I needed AptX support. I purchased another set of headphones with BT 5.x and AptX support, but I was still getting noticeable audio lag when gaming. With either headphones, I do not notice latency when watching YouTube or something like a movie on Netflix.

Check headphones that have game mode that can be turned on (with low latency).
