HI,
have found this weird issue: a simple sound, played via soundinterface, doesn't play on iPhone (iOS 14.2 or 13.3, tested on several devices). You can test simply on the background sound sample provided by Klaus:

The weird thing is that it plays on iPad (14.2) and that the soundinterface plugin, works. I have added an oncomple event on my test, and it gets fired, although the sound is not audible.
Any hint?
