Refactor audio handling with range checks, buffer threshold, and lock fixes

Browse source 
- Added range checks for handle to avoid invalid index access in AudioOutOutput, AudioOutSetVolume, and AudioOutGetStatus.
- Added a constant AUDIO_STREAM_BUFFER_THRESHOLD for the buffer threshold (was previously a magic number).
- Set the freq parameter correctly in the SDL_AudioSpec structure in AudioOutOpen.
- Fixed locking issues in AudioOutOutput to avoid unlocking before it's locked.
