This is a strange bug that I've encountered on all browsers on iOS or mac with m1 chip. iOS I've tested firefox and safari, on Mac I've tested Safari and Chrome.
I've built an app that creates some audio with BaseAudioContext.createBufferSource() and whether it's going to be played depends on couple of factors:
- running the web app locally -> works every time, no matter how many times I refresh or switch tabs;
- going to a deployed https page -> on first load everything plays normally, after refresh or tab switch it just stops working, nothing is played although the code is executed.

Going to Settings -> Safari -> clear page cache seems to help on iOS.
For mac Safari I have to go to Safari -> empty cache or for Chrome -> open dev tools and refresh the page.

example can be found here https://demiurg.app/tabs/tab-player.html?tabId=89

on windows and android devices there is no such issue, the audio plays each time I press the play button.

If this bug should be submitted elsewhere, please do that or redirect me to a correct bug tracker.
