Environment

- **OS**: iOS 17.6.1
- **Browser**: safari
- **.net Version**:

Anything else?

Interestingly, if I open a new tab and play a YouTube video while the tab is being played, the audio is now being reproduced. I can then stop and pause or refresh the page and audio will still work. When closing safari and opening it again it stops playing.

Unfortunately I don't have a device with your exact version available but for me its working fine using Browserstack with iPhone 15 iOS v17.5. Unfortunately on iPhone 16 iOS v18 i cannot hear any audio on browserstack (for any website and both chrome and safari) so its hard to reproduce.

It sounds to me like a system level problem of audio being blocked. Can you check if following websites are generating a sound for you. This would at least tell us if it is a general browser/OS problem or something that alphaTab does wrong.
