The error code -4001 when using the startPlayMusic interface in real-time audio and video (TRTC) typically indicates a problem with the audio playback initialization or configuration. This error might occur due to several reasons, such as incorrect audio file format, unsupported audio codec, or issues with the network connection that prevents the audio stream from being properly initialized.
For example, if a developer attempts to play a background music file using the startPlayMusic interface but the file format is not supported by TRTC, the system might return error -4001 to indicate that the operation failed due to an unsupported file type.
To resolve this issue, developers should ensure that the audio file format is compatible with TRTC requirements, verify that the network connection is stable, and check for any misconfigurations in the audio playback settings.
