In-Game: [HTML5] Calling audio_sound_loop_end() on a decoding streamed sound will cause a crash

[toby-yoyo]

Description

If a streamed sound is currently decoding, and audio_sound_loop_end is called on it, the runtime will crash due to an attempt to access the data buffer which hasn't been decoded yet.

This will produce the following error:

Uncaught TypeError: this.pbuffersource is null

Steps To Reproduce

• Open and run the attached project on HTML5.
• Open the console.
• Interact with the page to start the test. The game should immediately crash.
• In the console, scroll all the way to the top and inspect the first error to be thrown. It should be the one from the description.

Avoided refs to the voice's audio buffer when setting the loop-end bound on a decoding voice.
