No support for AptX HD/Adaptive even if SoC does

[OmarN]

When connecting a Bluetooth device that supports AptX Adaptive, the phone does not use the AptX Adaptive codec.

For phones that don't support AptX Adaptive, this is fine. However, phones that do/should support AptX Adaptive also do this.

For example, the A52 4G. The Qualcomm Snapdragon 720G inside it supports AptX Adaptive (but not AptX LL or HD). However, when connecting a set of AptX Adaptive earbuds (Soundpeats Truengine 3 SE 3040), it connects using AptX Normal. AptX Adaptive doesn't even show up in the Developer Options either.

It's not like I can use SSC or LDAC either as they are not compatible with my earbuds.

If anyone knows if it's a hardware or software limitation, and how to fix it using libraries, please let me know.

Hi @OmarN, thank you for bringing this to our attention. I have reached out internally to our team and will get back to you when I receive a response.

Hi @OmarN, thank you for your patience. Our tech team have confirmed that the A52 only supports AAC, aptX, LDAC, SBC, UHQ, Scalable Codec.

Hey Laura, i cant click on AAC,APTX,LDAC, Scalable Codec on my A52. Do you know what is the reason? I need your help

Hi @piece1st, are you referring to in Settings? 

The option being greyed out can indicate your connected headset is not compatible with that codec.
