Abstract
A self-diagnosis method performed in audio playback equipment including an audio playback unit having at least one loudspeaker and an audio capture unit having at least one microphone includes the steps of acquiring or producing emission audio test signals and outputting them via the loudspeaker(s), thereby producing sound test signals; acquiring reception audio test signals produced by the microphone(s) as a result of the microphones receiving the sound test signals; and analyzing the reception audio test signals in order to establish a first diagnosis of the audio playback unit and a second diagnosis of the audio capture unit.
