Has IOS13 broken tags used as audio buffers connected to the audio context?

问题

We are currently developing a website that allows users to play simple audio tags connected to the audiocontext. We are aware of technical issues with IOS such as playback initiated by user gestures. Everything is working fine up to IOS12. Now that IOS13 is out, nothing works anymore.

It works on all desktops, android and IOS up to IOS13.

Any idea on what is going on?

There are no error messages in the console when debugging with Safari on Desktop connected to the iphone.
