I have a Sony WH-1000XM4 headphone.
On my Android phone I have installed the Sony Headphones application.
On the upper bar of the application I see the audio is sent over to my headphones using AAC.
How can I have it send LDAC?
I have a 2018 smartphone, a Huawei Mate 20 Lite, with Android 10.
Maybe my smartphone is too old for LDAC?
