It should be noted that after calling <apiname keyref="setExternalAudioSink"/> to enable external audio rendering, the app no longer receives data from the <apiname keyref="onPlaybackAudioFrame"/> callback. Therefore, you should choose between this method and the <apiname keyref="onPlaybackAudioFrame"/> callback based on your actual business requirements. The specific distinctions between them are as follows:<ul>
