Audio Generator fails because player not started before getting stream playback.

Which demo project is affected:

Audio Generator

OS/device including version:
Windows 10

Issue description:

godotengine/godot#76324

Tried to use Audio Generator demo with Godot 4. If failed with an error due to $Player.get_stream_playback() returning null. However, moving the line $Player.play() to the line before this one resolved the issue.

I gave it a try and it looks like the issue has been fixed in #782. Everything seems to be working. This issue can be closed.

@zf-moth hi, the zip file in https://godotengine.org/asset-library/asset/2759 still doesn't reflect the changes. Thanks.
