Undocumented External Audio Fix Not Working on iPhone but is on iPad and iPod and Android Devices
Dec 18 2019 06:32 AM
Just a heads up for other developers encountering this issue. The code that Isaiah had posted started working with iPhone as well once it was moved to the start of main.lua. It was originally placed in a sfx.lua module, where it worked for Android devices, as well as iPods/iPads, but not iPhone.
If anyone has any ideas on why this is the case, I'm sure others would be interested in the why as well.
