Abstract
The invention relates to a Muting Circuit used to control the path of signal flow for the amplified audio signals from an audio CODEC in a dual audio subsystem. More specifically, to the muting control of the rear and front panel head phone/line out and microphone connectors for the audio subsystem of a standard PC system. The present invention implements muting on the headphone 1 line-out jacks while allowing the Front Audio Board to be optional without the need for jumpers.
