@PhungDuong, is it iOS 14.4 or 15.4? Are you also using AudioContext to render audio?
If you are not

@Teodor, a few thoughts/questions:
- is it new in iOS 15.4 or is it also happening before?
- instead of trying to resume, what happens if you create a brand new AudioContext?
- a sysdiagnose would help validating whether this is due to AudioContext being suspended. Can you send me one (youenn at apple.com) with timestamp of when the issue happens?
