Android Question Is there a way to play audio output on device speaker and bluetooth speaker simultaneously

[zharpg]

I'm a beginner on this developing/programming activities and i want to learn to create a simple app that can make an android device plays audio output on device speaker and on connected bluetooth speaker simultaneously. Currently using a tablet s9 ultra which has 2 speakers (left & right) output that plays stereo sound. I would like to use my bose bluetooth speaker as a subwoofer since it can punch pretty good bass sounds.

Is there a way to do this? Found a ~3 year old thread that shows someone unintentionally make this happens but i couldn't really understand how to do it: https://www.b4x.com/android/forum/t...e-bluetooth-and-usb-audio.140457/#post-890653

Any kind of help is much appreaciated
