Fmod unity: In Android device can not switch to earphone

Hi, I meet a question
We use fmod in our game,but in android device ,when playing a BGM,and plug in an earphone or switch to bluetooth, the sound can not switch to them, and still play in the phone, but in ios device it’s all right.
Do you have any advice?
tks

When dealing with mobile (iOS or Android) you will need to implement a function to check for changes in audio device lists in order to switch to the bluetooth device once detected. Bluetooth on both iOS and Android can be tricky and unpredictable due to the OS.
