This panel mount cable fits a headphone port to custom panel. The 2 1x3 header connectors connect to mother-board audio header which supports speakers cut-off function. Plugging of headphone on the custom panel disconnects motherboard's speaker socket located at the back of the PC. For Intel standard AC97 audio header, please note that there's only 1 GND pin provided in the header/pinout. If you want to connect both headphone and microphone ports to AC97 audio header, please use P110-030.
