Sound issue for ar-quicklook on my ios

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 ?

Is your device on Do Not Disturb by any chance? My iPad Pro mutes audio from usdz or .reality files while Do Not Disturb is active.
