Hi,
I created a simple scene in Reality composer : just an animated 3D model plus a behaviour with trigger = scene start and action is both animate model and play ambiance sound.
It plays nicely in the editor.
I exported and it plays nicely on my ipad pro.
But on my iphone (ios 15.4.1), it's just muted.
I tested both with stereo and mono mp3. What should I do please ?
