If then you also call RTCMediaPlayer.setLoudness and import the original loudness of the audio data used in audio mixing, the loudness will be adjusted to -20lufs when the audio data starts to play.

Return value:

• 0: Success.
• <0: Failure. See ReturnStatus for the reason.

Notes: You must call this API before calling RTCMediaPlayer.start to start playing the audio.
