Connecting P4P800 FP Audio Connector To Antec Sonata's FP Wires?
Jim Robertson
panel audio connectors to a P4P800 Deluxe's FP Audio connector pins.
The seven wires coming from my case's front panel audio ports are
labeled:
Ret-R
Ret-L
FPout-R
FPout-L
Mic
Mic Bias
Aud Gnd
The P4P800's connector pins are labeled:
MIC2 AGND
MICPWR +5VA
Lineout R BLINE_OUT_R
NC
Lineout L BLINE_OUT_L
Apart from the Audio Ground, I'm not sure which wire from the case's
front audio panel goes to which pin on the MB. Antec doesn't
apparently use the Intel front audio panel cable that the ASUS manual
refers to. Also the Antec Sonata manual refers to only 6 wires that
are have different names from the seven wires in the case itself, so
it has been no help whatsoever.
Any help would be greatly appreciated!

Paul,
Thank you so much for your knowledgeable and detailed response! It is
much appreciated.

Have you successfully connected up the Sonata's front audio to the
P4P800? I rearranged my Sonata's FA pinouts on the 2x5 header
connector to conform to the Intel standard but the microphone did not
work. I disconnected the FA connector to attempt to isolate the
problem, and I've just found the cause to be the buggy Asus SoundMAX
control panel.
However, before re-connecting the FA, I checked the Antec website and
found the following in the Sonata FAQ.
3. Microphone Power Pin: Connect the MIC connector to this pin.
4. Microphone Input Pin: Connect the MIC-BIAS connector to this pin.
This is contrary to my understanding of the pinouts. I haven't tried
either way after resolving the device driver issue for fear of
damaging my P4P800.
Can anyone confirm which pinouts are correct? I reckon Antec has a
typo in their FAQ but I have not received a response from them yet to
my inquiry.

Maybe you should try contacting "webm...@antec-inc.com", as all the
other contacts listed on the Antec page look like a joke. Their web
based problem submission looks like it might be linked to a third party
support organization. So, the webmaster may be able to redirect your
query to someone who actually works at Antec. I looked at the FAQ page
http://www.antec-inc.com/support_roductInfo_FAQ.php?Qnumber=5&FAQno=15
you mention and it looks counter-intuitive to me. Now, maybe their case
wiring is screwy, in which case they may be trying to undo their
error (i.e. two wrongs make a right :-)
So, I'm afraid you'll have to contact Antec, as I cannot guess at
what they are up to. If you have an ohmmeter, you could check the
case wiring. AFAIK, on a powered microphone "tip" (the end contact)
is MIC-IN, "ring" (the middle contact) is MIC-BIAS, and "sleeve"
(the one furthest from the tip) is GND. Be aware that not all
powered microphones work exactly the same way, so if you can,
you should get the tech data for your microphone, to verify this.
A picture of typical wiring can be seen here, in the section
"Connecting the circuit to soundcard". This website uses popups,
sorry for the nuisance:

Sonata's front panel MIC pinouts with a multimeter. The tip is MIC-BIAS,
ring is MIC and sleeve is AUD-GND. So the information at the
www.epanorama.net website appears to be consistent with that of the Antec
site in that the Sonata MIC pinouts were back to front (MIC vs MIC-BIAS) and
Antec appeared to be rectifying it by instructing people to reverse the
pinouts.
So I connected up MIC-BIAS to pin 1 and MIC to pin 3 at the front audio
connector. No joy. When plugging my multimedia headset to the Sonata FP, I
get audio thru the headphones but nothing thru the microphone (I tested
using Sound Recorder). I then plugged the headset to the P4P800 back panel
and as expected the microphone (and headphones) worked.
I then thought what if I wired it the way the pinouts are labeled, ie., MIC
is really microphone input signal and MIC-BIAS is microphone power? I tried
that and now BOTH back and front panel microphone ports do not work anymore.
So I'm back to square one as far as the front audio microphone is concerned
:-( . Any ideas, people?
I now have another question. I understand how the FP headphones work ...
the jack is a 3.5mm stereo switched DPDT socket---when unplugged, the
circuit is closed and audio is routed to the back panel (like having a
header block across pins 5-6 & 9-10 on the front audio connector. But does
it work the same for the microphone? Ie., if you connect a microphone at the
FP (assuming it works), does it disable the microphone port at the back
panel? Or does the 2 function in parallel?
I guess I'm again posing my original question ... has anyone gotten their
Sonata front panel to work successfully with BOTH headphones and microphone?
If so, can you please let us know how you connect up your microphone
pinouts?

The connector from the sonata to the mic connectors on the motherboard went
like this.... Works for ASUS P4PE and P4P800 motherboards...
Case Connector Motherboard pinout
Mic In Mic2
Mic Grnd AGND
Mic Bias Mic pwr
I did have to enable Front panel Mic in the Audio control panel to get it up
and running. Works great.

panel. My microphone now works from the Sonata FP when the checkbox is
checked. This is with FP MIC connected to MIC2 (pin 1) and FP MIC-BIAS
connected to MICPWR (pin 3).
I presumed that when it is unchecked, the microphone would continue to
function as per normal from the back panel. That is not the case for me.
Can Uncle Maddog or anyone please verify if your back panel microphone works
at any time? Or is it another case of a buggy SoundMAX device driver for
the P4P800? I still cannot download the latest driver file file from Asus
without getting CRC errors.
Cheers.

Speakers, headphones & microphones now work from both back and front panels.
It was late at night when I did my testing and I must have missed something.
Anyway, the good news is the microphone works both from the back and front
panels, the latter only when the "Front Panel" box is checked in the volume
control panel.
Thanks for everyone's assistance in this matter.
Albert.
