Abstract: An audio management method and apparatus, which relate to the field of communications technologies. The method includes: when it is detected that there is a first web page audio to be automatically played, determining whether there is an audio being played and whether a priority of the first web page audio is lower than a priority of the audio being played; when yes, intercepting automatic play of the first web page audio; otherwise, playing the first web page audio. A priority of a first web page audio to be automatically played and a priority of a web page audio being played are compared to decide whether to play the first web page audio, so that the problem of a conflict between web page audios is solved, and a user is not required to perform operations one by one.
