Front panel audio connectors

Specs: none yet, none yet

i just got a new case for my rig, and havee bin tansferin the stuff over to it. im pretty much done now but but its the audio cables on the front panel of the case that are confusing me.

the front panel has usb and audio, now i figured out how to connect the usb cables to a free connector on the mobo using somethin i found on google as a guide along with the mobo instructions manaual, but i'm left with the audio connectors now and I'm really stuck.

on the mobo they are listed as follows (i;ve tried to copy the diagram exactly as it shows):


BLINE_OUT_L - |* *| - Line out_L
* * - NC
BLINE_OUT_R - |* *| - Line out_R
+5VA - * * - MICPWR
AGND - * * - MIC2

Where there's a | around the connectors, these connectors have a jumper across them so I can't connect anything to them anyway.

Now, the case cables are as follows:


I gather i put ground in the agrnd connector, but what about the mic in and mic bias, why are their jumpers on the connectors on the motherboard preventing me from conencting anything to them? Can I just take them off with no side effects?

Most front Panel audio headers conform to the Intel standard this has 10 positions in two blocks of 5. These blocks are numbered 1,3,5,7 and 9 and 2,4,6,8 and 10. Each of these positions has a pin on it except for position 8 which is empty.

Your diagram is upside down. Pin 1 is your MIC2 and Pin 2 is your AGND. One thing on the list of connectors you have two RETURN Rs. One of these should be RETURN L.

Your connectors should be attached as follows:

Pin 1 - MIC IN PIN 2 - GND
PIN 3 - MIC PWR PIN 4 - No connector
Pin 7 - Not used Pin 8 - No Pin
Pin 9 -SPKOUT L Pin 10 - RETURN L

The jumpers on pins 5 & 6 and 9 & 10 are required if front panel audio is not connected. The jumpers are required for the signal output to be sent to the rear audio ports. Otherwise the rear Line Out connection will not work.

If your connecting front panel audio you remove the jumpers

Hope this helps

HI, I'm having the same problem but a little different.

With my audio:

I'm using the ASUS P4P800-E Deluxe

the manual has pin names of

Line Out_R
Line Out_L

and the names on the conectors

Basically, they have diff names and i have two EAR L cables and two EAR R cables and i dont know where to stick them, can somebody please help me match them up?? I can figure out the MIC cables and the ground but as far as the two EAR R/L cables, i have no idea. I'm not sure if color has any significance but thats the only diff i could find between the two.

Thankyou so much for your time and I would really appreciate your help,

i would hope that "EAR R/L" stands for "REAR R/L."

if thats the case substitute RETURN with REAR or "EAR."

Pin 1 - MIC IN PIN 2 - GND
PIN 3 - MIC PWR PIN 4 - No connector
Pin 7 - Not used Pin 8 - No Pin
Pin 9 -SPKOUT L Pin 10 - REAR L

thats actually what my motherboard booklet has.
it says REAR rather than RETURN.
and it says FRONT rather than SPKOUT

Hello, been hooking up my case front panel, and hit a couple of problems.

Got the USB & audio connected(after putting it in backwards) headphones work but the mic doesnt (it works when connected to the rear headphone jack or my sound card.

The other problem is my case also has an ieee 1394 firewire port, everything matches fine except my case FP has only one GND while the mobo has 3, and the mobo's power pin says 12v while the FP says 5v.

Is it safe to connect it up like this?

Im using the Asus P4C800-E Deluxe too.

Been trying to get this for 3 days now, so any help would be highly appreciated.

My case has two sets of wires instead of the single one and this presents a problem. The wires are Mic in, Mic bias(this is same as mic power), and Grnd; as well as Spkr-L, Spkr-R, and Grnd. The confusing part is the two grounds. My mobo is an Asus A8N-SLI premium and follows the standard fpanel layout.

I have a Thermaltake Soprano case that has the same problem with the ear connectors. And a A8N-sli premium mobo.It's for whats called front panel, but it's really on top of the case. I have discovered ( with much pain in the arse :))that if you connect the ear connectors from the case, your front audio will not work in surround sound. This sucks but you have to leave the top panel audio disconnected to get the surround sound audio to work. Unless of course you are handy with wire snips and connectors that are small enough to work on pins and not interfer with the other connectors. Then you can attach a jumper from the left and right ear wire from case to go on the bline out pins. Then your rear audio will work as well, but you will have to turn off your sound system when using the head set.

Then there is the option of just pluging the head set in the rear of the case. Much simpler. With regard to the IEEE1394 connectors on this case and mobo, good freaking luck! Took me all of 2.5 hours ( This included time for running after the longest and skinniest needle nose pliers on the planet) to hook this up. Each and every line for the IEEE1394 on this case is 1 lone pin connector. Not to mention the illustration in the mobo book for this and the game connector are upside down in relationship to the mobo, making it real easy to hook everything up backwards. Yes I did this, but fortunatly I caught it before powering up.
