Anyone know how I sould wire up the front panel of my case to my
motherboard (im not interested in connecting the microphone only the
headphone).

From the case I have leads marked "EAR R" (1 red 1 black), "EAR L" (1
white 1 black), GND, MIC-VCC and MIC DATA.

On the motherboard the connections are "Line out_R", "Line out_L",
"BLINE_OUT_R", "BLINE_OUT_L" MICPWR, +5VA, MIC2 and AGND.

I tried connecting the "EAR R" pair to the "BLINE_OUT_R/Line out_R" and
the same with the left channel and did indead get sound out, however it
sounded like someone had used a "remove voice" filter on the output ie
the music was slightly distorted and the singing almost completely
silent.

Any ideas?

MIC_DATA x mic2 agnd x GND
MIC-VCC x micpwr +5va x (no connection)
EAR_R x line_out_r bline_out_r x
(no connection) x nc
EAR_L x line_out_l bline_out_l x

If you can find a way of connecting line_out_r to bline_out_r while
the EAR_R wire is connected, then sound will also be available on the
computer's rear (lime) line out connector. Same for connecting
bline_out_l to line_out_l. Maybe that is why you are telling us
there are two wires on each EAR signal ? So they can be used to
jumper line_out to bline_out on each channel ?

The MIC-VCC wire connection to "micpwr" ensures that electret or
a passive monophonic microphone will work. "micpwr" is connected
to +5V via a 1K ohm or 2K ohm current limiting resistor, and
electret microphones apparently only need microamps of current
to work. An electret microphone gives about 20dB more signal than
a passive microphone. If you use a passive, you'll need to crank
up the gain via the "microphone boost" button. The wiring on a
computer mic jack should be:

Tip = Mic-Input (passive or electret input)
Ring = Mic-Pwr (with a voltmeter, you'll see +5V wrt the ground)
Sleeve = Ground

As for the funny sound, it could be due to running the speaker
system in a four or six speaker mode, instead of two speaker mode.
This filters some of the content and sends it to the other speakers,
to give a good sound "image". Other possibilities are that there
is an equalizer in the mixer panel, and it is adjusted away from a
0 dB (passthrough) type setting. You might also look to see if
some special effects have been enabled.

HTH,
