Microphone problem w/ ASUS M4A88TD-V EVO/USB3

M4A88TD-V EVO/USB3 MOBO in new build works great except that microphone input using either rear panel or front panel is poor. Volume is very low unless I adjust RealTek sliders in which case background noise becomes loud and completely unacceptable. Speaker output is fine. Same microphone works fine in old Dell desktop. Sound drivers are up to date. Win 7. Antec 300 case. I'm completely stymied. Thanks for any help.

This is probably a long shot, but try disconnecting the front panel connector cable from the motherboard and using the rear mic jack, with the sliders turned up. I have this case and found that the front sound/USB connector cables too short to easily route away from other cables and picked up lots of electrical noise. Worth a shot to see if that cable is the origin of your background noise.
 
Manticorps, thanks for your speedy reply. As you suggest, worth a shot. I will give that a try.

BTW, for the Anttec 300 front panel audio, I'm currently currently using the the HDA connector. As I'm writing this, I'm thinking that perhaps I should be using the legacy AC97 connector (and maybe that is causing the problem). Any thoughts?

I'm using the HDA connector as well, though it might not hurt to try the AC97 connector if you can't get things sorted out.
 
Per you suggestions:
Disconnected front panel cable -->No change.

Tried AC97 Connector-->No change, except system did not detect mic when plugged into front panel jack.

So not much progress, but did eliminate some possibilities. Thanks for taking the time to respond and for your suggestions.

I wonder if there is any good way to establish if this portion of the mobo is defective.
 
I thought it was a longshot, but worth a look. Maybe poke around in control panel>sound and hardware settings. Sorry that I can't be of more help.
 
Update: I connected a Logitech Headset (connected via USB) and its mic and headphones worked perfectly. I was able to record w/ audacity and the result was excellent. So I don't understand the significance of the fact that the usb connection works fine, but the audio input jack (neither rear panel nor front panel) does not. Since the mic I use for the audio input test is the same mic that worked fine on my old Dell desktop, I'm remain puzzled. Anyone have any ideas what might be going on?

In any case, I'm relieved that I can at least record with the Logitech.
 
When you changed to AC'97, did you remember to change it in the BIOS? It won't work unless it's set properly.

I had an annoying problem with the rear mic port on an ASUS board... the only solution was to use the front port :\.
 
Lennyh, did you ever get your regular microphone inputs working better, I have the same board and have the same issue.
 
No, I never did get the mic inputs working. I've since bought a logitech webcam (C310, I think) that includes a mic and that works well, just like the logictech headset. It also connects via USB rather than the mic inputs.

It's possible that the mics I've been trying do not generate a sufficiently strong signal (although it's strange that they work fine on my old Dell).

Sorry I don't have a better answer. If you ever discover something, let me know, and I will do the same. Although since the USB connection works fine, I likely won't be messing much w/ the mic inputs. (Still would be great to get this figured out.)
 
I as well am having good luck with my webcam via USB,

One more question, are using either DVI or HDMI via on board video for your monitor connection? I am forced to use the VGA connection as both digital connections produce a pixelated green screen. I am still trying to figure that out as well. Hope I don't have to replace the Mother Board.
