If you don’t want to connect to the front audio header, pins 5 & 6, 9 & 10 have to be jumpered ON THE MOTHERBOARD in order to have signal output directed to the rear audio ports. Otherwise, the Line-Out connector on the back panel will not function.

Intel Front Panel Audio Header Pinouts

The analog front panel header design lets OEMs and integrators place audio functionality on the front panel of a PC system via a cabled up front panel dongle. This document describes the header pinout configuration for connecting chassis with Intel® High Definition Audio or AC'97 audio cable up.

Note: Intel® High Definition Audio headers are pin-compatible with AC'97 chassis and connectors.


 

  For Intel® High Definition Front Panel Audio
Pin Signal Name Description
1 PORT 1L Analog Port 1 - left channel (Microphone)
2 GND Ground
3 PORT 1R Analog Port 1 - right channel (Microphone)
4 PRESENCE# Active low signal that signals BIOS that an Intel® HD Audio dongle is connected to the analog header. PRESENCE# = 0 when an Intel® HD Audio dongle is connected
5 PORT 2R Analog Port 2 - right channel (Headphone)
6 SENSE1_RETURN Jack detection return for front panel (JACK1)
7 SENSE_SEND Jack detection sense line from the Intel® HD Audio CODEC jack detection resistor network
8 KEY Connector key
9 PORT 2L Analog Port 2 - left channel (Headphone)
10 SENSE2_RETURN Jack detection return for front panel (JACK2)
  For AC-97 Front Panel Audio
Pin Signal Name Description
1 MIC Front panel microphone input signal (biased when supporting stereo microphone)
2 AUD_GND Ground used by analog
3 MIC_BIAS Microphone power / additional MIC input for stereo microphone support
4 AUD_GND Ground used by analog audio circuits
5 FP_OUT_R Right channel audio signal to front panel (headphone drive capable)
6 FP_RETURN_R Right channel audio signal return from front panel (when headphones unplugged)
7 AUD_5V Filtered +5 V used by analog audio circuits
8 KEY No pin
9 FP_OUT_L Left channel audio signal to front panel (headphone drive capable)
10 FP_RETURN_L Left channel audio signal return from front panel (when headphones unplugged)

This applies to the following motherboards:

D101GGC
D915GAG
D845GVSR
D865GVHZ
