Questions about Sounds vs AudioPlayers

Is there a big difference between Sound Instances and Audio Instances? Is one better than the other? Will Sound Instances be deprecated in favor of AudioPlayers or is it okay to use Sounds in newer places?

Sound instance is for very basic things.
I don’t see any reason to use AudioPlayer if sound instance provides enough API for you.
I would recomend to structure game to support both and only use AudioPlayer when you really need that.
