I’ve noticed that when I change the default playback device from the bottom right of my taskbar, FMOD still continues playback on the previous device. While going through some other posts I got to know that there is System::setDriver that can be used to switch audio devices, but since UE4 (and literally every other active application) switches the audio device automatically, I was hoping that this capability is present in FMOD too? I also noticed the same behavior in FMOD studio. The studio also does not auto switch to the default playback device. It needs to be changed manually from preferences.
Note: I am not plugging in a new device on the fly. The playback devices are already connected and I am only switching between them.
