Hi, I'm getting the same crash in the simulator on iOS 12 and iOS 13 devices but it works fine on iOS 14 simulator devices. I don't think this is anything to really worry about as I've looked at my Google Firebase Crashlytics reports and don't see any crashes on real devices in alcMakeContextCurrent on both of my apps that use OpenAL. Therefore I'm hoping it's just a problem with the simulator, maybe because OpenAL is deprecated now ?
