Only for A1 and A2 logical audio ports:
If the
character 5 is C (11 00), which means signal is present but
the cable connection status is unknown - the explanation is a logical port has no pin that can indicate the
connection status so this is always unknown. When the character 5 is 8 (10 00), that means there is no
signal on the port.
