Hello, I’m developing a game for mobile phones. I want to listen to the sounds that are playing in the game instantly from different audio output sources. I’m very new to FMOD and I don’t know about changing the output source. Can you please help me?

Hi,

The Core API will automatically detect when the output source changes, further explained here: [FMOD API | Core API Guide - Audio Devices](https://fmod.com/docs/2.02/api/core-guide.html#audio-devices-automatic-detection-of-device-insertion-removal), unless it is has been deactivated by registering the `FMOD_SYSTEM_CALLBACK_DEVICELISTCHANGED`.

When changing devices is the system not changing by default?

I didn’t mean to bump this, it showed up under new ☹
