Hi there. I have a similar problem. I have a tyan S2098 board
installed and the front (acer) connector is the same one you have. I
have connected the usb ports, they seem to work with some things and not
with others. But I can't seeem to figure out what I need to do to
connect the audio. I am fairly adept at working with electronics, so I'm
not afraid to make some modifications. Did you ever figure out how to
add audio to your front panel connector? Perhaps we can trade help,

Thanks!!
