Abstract
A sound card and related method includes a sound processing circuit, a rear primary connector, and a switching connector header coupled therebetween. The switching header includes a normally closed spring contact that opens in response to insertion of a plug in the header. Upon opening of the connector header switches, the audio signal is received by a secondary connector coupled to the plug and disposed at the front of a computer. The secondary connector has a normally closed switch that enables the signal to pass back to the header and to the primary connector. Each of the primary connector and secondary connector may be auto-muting to interrupt the audio signal at a main output contact in response to insertion of a headphone or other jack therein. The sound card is operational either with or without the secondary connector.
