interruptionListener crash when switching out of app about theamazingaudioengine HOT 7 CLOSED

So it seems to be caused by the fact that I release my audioController when I'm done with it. I guess in the meantime I will just permanently hold a reference to it in my App Delegate, but that seems wasteful.

Hmm, interesting! I never really designed the engine to not be around for the lifetime of the app, so I may well have missed a few things. In this case, the problem is the audio session interruption callback (the one setup in AudioSessionInitialize) isn't being unregistered.

I'll take a look a bit later.

Aghhhh it turns out I need to reinitialize the audioController whenever I also use the hardware video encoder after using the audio encoder, or the audioController no longer is able to start: and returns a nondescript error.

It also looks like there is no way to EVER clear the interruptionListener because Apple's docs say you can only ever call AudioSessionInitialize once per app launch. :(

I attempted to fix it with this commit: OpenWatch@eb92e78

But now I see a new issue with deadlocks on the main thread: #29

I'll let you know if I figure out a workaround...

I've applied a similar approach to fix the crash, in SHA 0bebf9b - I haven't noticed any problems so far though

Thanks for the quick response! That's a much cleaner workaround, although I notice you don't abort if *THIS == nil. I guess you can theoretically send messages to nil all you want, but I generally prefer to explicitly test for it just in case something weird happens as a side effect.

I haven't tested your fix, but the diff makes sense to me, so I am going to guess it works and close the issue. :)

Ah - I'm an idiot, I totally forgot to add that part =) Fixed in SHA a183790
