I  have the amd computer with ASUS motherboard
the microphone option on the computer is not working
I have uninstalled and redownloaded the sound card driver from ASUS website
but its not enabling the that option I have formated the computer  reinstalled win XP But still no luck.
Any other ideas :-/Are you plugging into a jack in front or in back?  If in front, did you also try the ONE on back?  The one on front may not be wired.  

What audio control software are you using?  To check your settings through Windows XP's Sounds and Audio Devices Properties panel, go to Control Panel and open Sounds and Audio Devices.  Select the Audio tab.  Click on the Volume button under Sound playback.  Is Microphone muted?Well I have only one jack at the back of my computer .So it is plugged into the pink jack which was for microphone.The sound hardware that I am using is already built on the motherboard it model number A8N-VM and when I try to run the software wizard of windows Xp control panel icon it not able to hear any sound .When I open the control panel of onboard sound card the line in option shows me grayed out and I have CHECKED that the microphone is not muted.but not able to find any reason for not workingDo you other audio control software installed besides Windows standard sound control panel?  I have an add-on sound card which I installed to replace onboard sound.  I installed software with the card.  This panel is part of the control panel in that software:


Without that box for Enable Microphone Booster checked, I basically get no sound from my mic.  Do you have any such control somewhere in your software?I did installed the software for onboard sound card and also check for micrphone booster uncheck and recheck. Check for audio properties and what ever was possible in windows XP software sound card troubleshooting but looks like It might be hardware issue now 'cause everything else is working but not microphone Try loading windows sound recorder.An add-on sound card might be the best, and perhaps only, WAY to resolve this.  Here's an inexpensive card that I'll recommend because I bought one in April 2005 and have been using it since then: CHAINTECH AV-512 5.1 Channels PCI Interface Sound Card - RETAIL.  Of course, there are many cards costing more if you're willing to spend more.  

This card is the one I use a mic with.Good advice soybean...i have 2 Chaintek's myself.
