When the "Enable Zero Iteration" and "Use ML Audio for Zero Iteration" settings are both checked, the audio doesn't play inside Unreal Editor. This happens in the following cases:
This shouldn't be happening, the audio should be played via ML device only when testing it on the device via Zero Iteration.
This was tested and reported in 4.25.1 (CL-13594126). This was reproduced in 4.24.3 (CL-11590370) and Main 4.26 (CL-13653677)
Results: The audio doesn't play, there is no sound and it stops immediately
Expected: The audio should play. When checked, the option "Use ML Audio for Zero Iteration" should affect only the testing of the project via Zero Iteration, not playing audio files in editor
