Issue description

If an AudioStreamPlayer, AudioStreamPlayer2D or AudioStreamPlayer3D is playing with an invalid VolumeDb float value ( NaN ), the whole audio stops working. There's no error displayed anywhere, so it can be confusing to find the reason. It seems to happen only if this invalid audio is playing before anything else is playing.

This can be a problem since giving a negative value to Mathf.LinearToDb( float value ) returns a float.NaN, and it can be a common mistake. Since there's no error given, finding this error can be hard.

Possible solutions could be:

• Displaying an error when an AudioStreamPlayer, AudioStreamPlayer2D or AudioStreamPlayer3D has an invalid VolumeDb value
• Preventing AudioStreamPlayer, AudioStreamPlayer2D and AudioStreamPlayer3D to have an invalid VolumeDb value
• Preventing to play the AudioStreamPlayer, AudioStreamPlayer2D and AudioStreamPlayer3D if VolumeDb is not a valid VolumeDb value

Steps to reproduce

• Create a new project and a new scene
• Add two AudioStreamPlayer, AudioStreamPlayer2D or AudioStreamPlayer3D
• Assign one loop audio to the first one.
• Set the VolumeDb from script to a NaN value
• Play the audio
• Here the audio doesn't play, but the node stills try to play it infinitely. From here audio doesn't work even if it's played from another node.
