Audio queue/playlist

[superbluecool]

Anyway to do this? Would be super helpful to be able to have a queue/playlist. Thanks

This could be implemented by subscribing to the PlaybackEnded EventHandler and reading from a collection/queue.

I'll leave this issue open as a reminder to write a sample.

Starting a new sound in PlaybackeEnded results in the following error right after calling player.Load(...:

Could not initialize an instance of the type 'AVFoundation.AVAudioPlayer': the native 'initWithContentsOfURL:error:' method returned nil.
It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOnInitFailure to false.
