An apparatus for retaining a component that transfers solid-borne sound includes a solid-borne sound damper having at least one spacer made of brake lining material arranged in association with the component. The device also includes a memory for storing the data bits and the parity bits of each code word, and includes an error detection circuit, which is formed to detect an error of the data bits in a code word by evaluating exactly one subset of the stored parity bits of the code word. The switching device is switched on to couple the circuit node to ground when power is applied to a control terminal thereof from the HDMI sink connector power pin, and being switched off otherwise.
