Antec Sonata case/ASUS A7N8X Deluxe mobo front panel audio trouble

I recently tried hooking up my front panel audio connectors of my Antec Sonata case to my ASUS A7N8X Deluxe mobo, and for the most part it's been successful (audio output is fine) but the microphone input still isn't receiving anything.

I've checked the site and it said that the MIC connectors were mislabelled, so I tried switching the MIC and MICPWR connectors both ways but I still don't get any kind of input.

Can anyone help?

Are u sure you've got the mic channel selected as input in advanced audio settings?

What do you mean by that?

For me, if I use my rear mic plugs (the ones directly connected to the mobo) then it works just fine, but something screwy is up with the font panel's connections.

Blue Rishi is referring to your audio mixer (volume control) in Windows (if that is indeed what you are using). Double click the speaker icon that you use to adjust your volume to get to the mixer.

Sometimes the Mic channel in the mixer is disabled/volume down low, which would make it seem like the port isn't working.

You may also have to change your mixer from 'playback' to 'recording' to see a few more channels, do this by clicking on 'Options' -> 'Properties' in the mixer.

That's what I thought, but no dice...I've had those enabled already.  I'm thinking this is a hardware problem.

Any experts have any experience with the Sonata's front panel connectors or the A7N8X Deluxe's mobo?

I have a Sonata due here tomorrow, however an Abit AG8 board is going in. Sitting behind me is an A7N8X-X, but in an older case without front audio connectors!! :(

The Asus manual I've got says that the audio header on the motherboard should be like this:

+ + +    +  AGND, +5VA, BLINE_OUT_R, [blank], BLINE_OUT_L
+ + + + +  MIC2, MICPWR, LINE_OUT_R, NC, LINE_OUT_L

Does your case have audio connectors that are loose (one wire, one connector), or are they all in one connector unit that you simply plug on?

Check the Antec website for Sonata FP Audio.. I am pretty sure this is standard and nothing really to take note of.

The Asus board has the std Intel 10-pin spec. connector...

No, none are loose.  The front panel audio output works perfectly except for microphone input, so I know for sure it has something to do with the MIC2 and MICPWR connectors.  As per Antec's Sonata FAQ goes, I hooked up MIC2 = MICBIAS and MICPWR = MIC, but still nothing.

And I used the individual connectors instead of the single unit.

*shrug*
Any dodgy/loose wiring on the where the Mic port is?

Failing that, I'll test the Sonata that arrives tomorrow and let you know how it goes.

Sorry for my short reply earlier, but it was very late here. Yes, I was reffering to the windows' mixer settings. Since you have a nforce mobo, I assume you have nforce audiodrivers and have set input to microphone 2, with volume(input) setting at least as high as with mic1(=backconnection).
The reason I brought this up was that 9 out of 10 times this is a mixer setting problem. The fronpanel should be connected like this:

  GR  +5 BLOR NC BLOL
   *    *    *    *    *
   *    *    *    *    *
MIC2 MP LOR NC  LOL
  |     |
  |     |
  |     | -- MIC (power lead)
  | ------ MIC-BIAS

This pin-out is the same for most asus boards, I've checked 3 manuals including your boards'...

If it's still not working: try another microphone, with less resistance (ohm) and another program for testing the mic.
If this doesn't work, I think this is a driver/mixer problem...

If you have a jackplug (thats what we called it Holland; I mean standard mono 3,5 headphone connector) and a multimeter laying around, you could measure resistance (ohm) from frontpanel mic connector to the end of the cable to see if it's broken (ohm = 1).

After fiddling with the mixer options, as suggested, I deduced to problem to be that I had to set my mic input to alternate in the sound properties' control panel.  The problem was that it was still set to the main input (the back panel) and didn't recognize the front panel's inputs.

Thanks for bringing it to light, Blue_Rishi :-).
