A system (1) for processing audio signals comprises an audio processing unit (9) for providing audio signals, an output unit (10) coupled with the audio processing unit (9) for receiving the audio signals and for outputting audio information based on the audio signals, a volume control device (2) which is adapted for receiving user input and controls a volume of the audio information depending on the user input, and a control unit (7) which is adapted to determine at least one parameter indicative of the volume of the audio information. In the event that the control unit (7) determines that the at least one parameter indicates that the volume of the audio information is equal to or greater than at least one volume threshold (30, 31, 32), the control unit (7) provides an output signal to at least one component (8, 9) of the system for triggering at least one additional function other than associated with controlling the volume of the audio information. In this way, the system may be triggered to perform an additional function in the background without requiring an additional action by the user.
