Abstract: A method for testing an audio signal system having multiple audio component connection sockets, each socket having at least one audio signal interface connected to a ground interface of the socket via a series circuit including a resistor and a capacitor, including feeding, via a signal processing device, a time domain reflectometry test signal into a wired network of the audio signal system, in which the sockets are connected to the signal processing device via differently lengthed electrical lines, detecting in a temporally resolved manner, via the signal processing device, test return signals reflected at the multiple sockets, comparing the detected test return signals with a temporally resolved reference pattern for test return signals, which reference pattern was created under predefined boundary conditions, and determining a faulty connection of a socket if comparing the detected test return signals with the reference pattern reveals a deviation above a predefined threshold value.
