Motherboard sound issues

Hello. I just got a brand new custom built computer, only to find out that when I plug my stereo speakers into the back lime green port, I get almost nonexistent sound. I plug them into the front lime green port, and they work perfectly. Is something wrong with the back audio jack, or do I not have something plugged in correctly? Thanks in advance.

    Thanks for the quick reply. The black sound out jack is for the rear speakers in a surround sound configuration. I only have two speakers (a 2.0 system). i remember reading another one of your posts to someone else telling them to use jumpers? or to unplug something?

    I have HD audio as well and it seems the problem was that HD audio was not configured in the BIOS. The person who built my computer enabled HD and soon my speakers worked perfectly.
    Thanks for all of your help.

Hi antlob,
Normally one would think something is wrong but if you look at page 2-23 in you're manual you'll see you're using the wrong plug-in (Lime green) (Rear). Plug you're spreaker jack into the
(Black sound out jack). See if that makes a differance?
To fine tune you're sound you can open Asus/RealTek sound effect manager listed in control manager. This program has connector sensing software & other goodies.

    That other person had called Asus so he could use HD for the front speaker out jack. He also noticed a differance in sound & soon lost the out-put at the rear speaker jack. Bottom line is if you want to use both front & rear (bounce between them), than use the black jack at the rear but if you intend to use just the rear you'll need to remove the FP_Audio connector from the motherboard & place a two (2-pin) jumpers across pin 5 & 6 and the other across pin 8 & 9.

    Pins 8 & 9 are the last two pins to the right of the set of pins for FP_Audio. See pg. 2-29

    Hope this helps!

Unpluged my computer to get repaired, have 3 different speaker type plug ins the back, don't remember which one to use. Their color coded, blue-green- pink

In many cards, the microphone connector will be pink, the speakers or line out or headphone will be lime green, and the stereo line in will be light blue. Additional jacks may be present on newer soundcards for rear and mid surround speakers.

This is a widely accepted color standard for computer sound card input and output jacks, but connector colors may vary between different brands. If you think you have a nonstandard card, consult your soundcard's manual or the manufacturer's web site before making any connections.

Hello...I have an issue with my speakers. My husband ran our speaker wires from our computer to our stereo and I can't get it to produce sound please help!!!

Be sure you plugged the plugs into the right ports on the back of the stereo.

From the computer: ensure you plugged the cables into the Auxilary Out, or Out jacks of the sound card.

On the stereo: ensure you plugged the cables into any open set of Auxilary In jacks.

Once you verify your cables are plugged in correctly, verify the input on the stereo is set properly. Set your stereo's source or input to "Auxilary" or "Auxilary 1 or 2." This allows the stereo to pull input from the cables running into the appropriately selected Auxilary source.

That should help hopefully.

If you still can't get sound, double check your computer's sound card settings and be sure the sound card is working properly.

You can test your speakers by plugging the lime wire into a headphone socket of something that plays OK.

The speakers themselves don't need drivers, but the sound card in the computer does. If yours are missing you can find them online. If this is a name-brand computer, visit the manufacturer's website and follow the link to support and downloads. For a home-built or custom-built machine, you will want to get drivers from the motherboard manufacturer if the sound is integrated, or the sound card maker if it's a separate card. Since you don't give the brand of computer I can't give you any specific links, but a few minutes searching on the Web will give you the URL.

If the drivers are installed and Windows recognizes the sound card, but you just don't get sound, be sure the speakers are plugged in to the right jack, the sound card settings are correct, and that the speakers have the right power connected. Sometimes it's easy to overlook the obvious things.

Sound not working properly!!!

Run microsoft update and make sure to select all updates (even optional). You will see hardware updates (if there is any) and this may fix the issue. Let me know if not.

Good Luck!

No audio on custom built computer using Abit NF8V

I'm assuming you have the little jacks for the speakers to plug into.... As crazy as this sounds, make sure you have the speakers plugged into the right jack. The icons by the jacks are not all that clear. You might have the speakers plugged into the "Line In" jack? I've done it myself and I'm a Computer Engineer!

Looking at the manual page 3 of the pdf says Connect the lime green 3.5mm stereo cable (hardwired into the right satellite) to the lime green input labeled ?FRONT? on your sound card. So your right speaker should have a cable with a green end that plugs into your standard audio out jack If you have multiple outputs and don't know which you are set up for, then turn the speakers on and up, put a long song on, and plug that green wire into every jack on the PC! If you've got no other issues you'll hear something! Good Luck
