Separate App Sound is a handy Samsung feature that lets you fix this, and it does it brilliantly. This can be a problem when you’ve only connected a Bluetooth audio device to listen to your favorite songs or a podcast. It’s a simple feature that lets you divert audio from apps to a specific audio device. So, instead of treating your Bluetooth device as all-or-nothing output, you can pick exactly which apps get to use it. Then, go to the Audio device and choose the Bluetooth device.
