The invention is applied to the field of television control, and provides a television and an audio external play control circuit thereof. The audio external play control circuit of the television comprising a power supply module, an on and off detection module, a power amplification module and an audio output control module is adopted, so that the working condition of the power amplification module can be controlled according to voltage change of the power supply module, so the television is prevented from outputting current surge sound to a built-in loudspeaker or an external passive speaker when being turned on and off, meanwhile, output channel handover can be carried out on a left sound channel digital audio signal and a right sound channel digital audio signal according to an access state of the external passive speaker, so that the phenomenon of mixcellaneous interferences occurring when audio play is carried out is avoided. The whole audio external play control circuit of the television has the advant
