i can make a demo using tw empty, importing charlie’s 3 tiddlers
and it plays “i play sound on render” fine locally and when served on the web for chrome, brave, firefox (mac)
however, safari behaves oddly; locally on desktop it works. but when served on the web it does not work. quine (ios) also does not work to play the audio, possibly for the same reason
does anyone know a workaround? (it seems it is a safari web audio api quirk – but why would it work locally on safari on mac but not when served via web to safari on mac? v. strange…)
