1. An electronic apparatus (100) comprising:
a first port (165) configured to receive an incoming audio signal;
a second port (160);
a controller (260) configured to be coupled to the first port (165) and the second port (160); and
a switch (290) configured to selectively decouple the controller (260) from the second port (160) when the first port receives the incoming audio signal, wherein decoupling the controller (260) prevents an electrostatic discharge occurring on the second port (160) from reaching the controller (260) when the controller (260) is receiving the incoming audio signal from the first port (165).
