I'm running an Intel D945GSEJT board, which uses an audio header + a stereo hookup at the back.
Im fitting it to a VoomPC case, but also have an HQCT v1 installed.
I'm struggling to work out the audio routing in the case.
My VoomPC has 2 x phono outputs on the front panel, but no stereo output or mic input, So currently if I want to use the phono to connect to my car speakers then I cant connect the HQCT or a mic for the car kit...
Board Tech Spec:
Then the pinoutThe board contains an audio connector on the back panel and audio headers on the
component side of the board.
• Back panel audio connector:
- Line out
• S/PDIF header:
- 3-pin header
• Front panel audio header (supports both AC ’97 and HD Audio):
- 10-pin header (for headphones/mic)
• Internal mono speaker header:
- 2-pin header
- Supports a 1.5 W/8 Ω speaker
The front/back panel audio connectors are configurable through the audio device
The audio stream for the line-out port is routed according to these dependencies:
• By default the audio stream is down-mixed to mono and amplified for an internal
• A connection is detected at the rear line-out port, the audio stream goes to the
rear line-out port and the internal mono speaker is disabled.
Pin 1 - Ground
Pin 2 - S/PDIF out
Pin 3 - VCC (5V)

I am quite happy to make my own leads etc.
I'm thinking I need a mic socket, some kind of aux input (to connect the HQCT) and then the standard phono sockets at the front...
Using AC'97 I'm guessing pin 1 and pin 3 to connect to the mic, but any ideas which pins to connect the HQCT?
I've got no idea on the other pin out
