REVIEWED: Formating, tested sound examples

This is happening because the processing function keeps reading audio
data from the AudioBuffer even after it has been marked as stopped.

There is also an error in ReadAudioBufferFramesInInternalFormat() where
if it is called on a stopped sound, it'll still return audio frames.
This has also been addressed with this commit.
