Are you sure the green connector on the SupremeFX II isn't your AAFP
header ? It kinda looks like it. Check for a legend printed on the
SupremeFX II in white letters, as to what kind of header that is.
In the third picture, you can just see "AAF..." in the picture.

Both original SupremeFX and SupremeFX II have the green header -
but the SupremeFX and SupremeFX II are apparently not interchangeable
between their respective motherboards.

Paul,
Thanks - you gave an answer for my follow-up questions, even before I had
posted them.
In this picture, it looks like there is another header in the SuprmeFX II in
addition of the AAFP1 green header.
Do you know what it could be? In the
http://pics.computerbase.de/1/8/1/8/7/16.jpg picture it looks like a extra
power supply connector.
Best Regards, Ollie

Again, check for any legend text printed in white letters.
The connector looks to be an "Aux" or "CD" four pin connector.
I have examples like that, on the surface of my P4C800-E Deluxe
board. That would be my guess, but check to see of you see
some letters printed next to it.
A "CD" one would not be needed, because you can set the optical
drive to use "DAE" or digital audio extraction. So it isn't necessary
to string an "antenna" between the CDROM and the sound card. Sometimes,
you end up getting noise pickup using the old analog cable method.
The four pin "Aux" one might be something you'd use, between a TV capture card
and the sound solution. On my TV card, there is a connector on the
faceplate instead, and that is how the TV sound gets to my sound card.
(If the thing had been designed properly, it would also have been
possible for the sound to be handled completely by the TV card, but
I guess one of their engineers was asleep.)

I agree that with the Sonata, only five wires should be connected.
Basically, the Sonata jacks have three contacts (tip, ring, sleeve).
MIC and MIC_PWR are tip and ring on the microphone jack.
LINEOUT_L and LINEOUT_R are tip and ring on the headphone jack.
Audio_GND is a common ground for sleeve on both jacks.
That means 1,3,5, and 9 on one side are to be connected
(MIC, MIC_PWR, LINEOUT_R, LINEOUT_L). And the ground on
pin 2 is AUD_GND on the Sonata. There is no need to wire
up the return wires, because an HDAudio system (faking AC'97 header)
does not use the return signals.
(This is copied from a Sonata manual I have on disk. Don't
connect item 6 and 7. I added signal names to the end of each line.)
1. Microphone Signal Pin: Connect the MIC connector to this pin. MIC
2. Microphone Power: Connect the MIC-BIAS connector to this pin. MIC_PWR
3. Ground Pin: Connect the AUD GND connector to this pin. GND
4. Front Right Speaker Out Pin: Connect the FPOUT-R connector to this pin. LINEOUT_R
5. Front Right Speaker Out Pin: Connect the FPOUT-L connector to this pin. LINEOUT_L
6. Rear Right Speaker Out Pin: Connect the RET-R connector to this pin.
7. Rear Left Speaker Out Pin: Connect RET-L connector to this pin.
HDAudio has enough channels in the sound chip, that return
signals are not needed (to support a sound muting function
when the headphones are plugged in). HDAudio can fake the
mute function, simply by having separate sound channels for
everything, detecting when headphones have been plugged in,
and then muting the green connector on the back of the computer.
One thing I do not understand about current HDaudio silicon, is
how the jack sensing is done. I know that some companies have
patents for audio sensing, where they measure the impedance
of the connected device. The connected device is not DC
connected, as virtually every input and output on a
sound chip is AC coupled with a small capacitor. When you look
around the sound chip, you should see a pile of small caps for
that purpose. To measure the impedance, they'd need to do
something like insert an ultrasonic signal into the jack,
and sense the current flow. Or something similar. The
exact mechanism is never detailed in the CODEC datasheets.
The Azalia standard from Intel, addresses the use of "side contact"
pairs on the jack. The jack has tip, ring, and sleeve. That
is three contacts. But, in theory, a jack can also have an
isolated pair of switch contacts, and the switch closes when
a plug is inserted in the jack. These switches are connected
to (2) four resistor trees, so that a total of eight jacks
can be sensed. The varying DC voltage value from the resistor
tree, is fed to a couple sense pins on the CODEC, digitized,
and that gives a four bit value for each tree, indicating which
jacks have plugs in them. All the complexity is necessary, so that
only a couple pins are needed on the CODEC, to detect jack
presence.
Since the vast majority of computer cases are still AC'97, they
don't have the side contacts on the jack. The last time I looked,
I wasn't even able to find the proper jack for sale to do it.
That means jack sensing is done using the proprietary or patented
method, without need for the resistor ladder or sense pins. It
means "FSENSE1" and "FSENSE2" in the above table wouldn't be
needed, and neither would there be a need for PRESENCE#, since
the header is not HDaudio.
So only five wires should be needed, just enough to get the
basic audio signals to the two jacks in question. The rest of
it seems to be covered by the CODEC, by means I don't understand.

PS. I got my P5E just today and I can confirm that the other connector is
for audio input from DVD/CD. If I only had the SupremeFX II manual, it would

Guessing at the connections isn't a lot of fun. It would at least
be nice for them to confirm that standard pinouts are being used.

Hello,
I have read your posts, and I tried, but doest work with my case. First
of all the ADH front panel drives me crazy... because I never meet this
situation
I have the the connectors:
- mic in
- mic vcc
- line r
- line l
- ear r
- ear l
- gnd
I just want to make the headset work... I dont care if its HD AUDIO or
AC 97. Any suggestion, how I could make that?
Thank you!
Paul
The original thread is here.
And is the motherboard P5E, or is it some other motherboard ?
It would be nice to verify the actual motherboard you're
using, just to be sure.
On P5E, the ADH is a digital header. What you're looking for is
analog signals, for a microphone and headphone on the front of
the computer.
The AAFP connector on the Supreme FX II card, is where you want to be
connected. You will be connecting only five wires. Line_R and Line_L
have no place to connect to. Your front panel "Line" jack will not
work. Only "MIC" and "EAR" will work.
- mic in
- mic vcc
- line r (make no connection)
- line l (make no connection)
- ear r
- ear l
- gnd
AAFP should follow the standard pinout. The "missing pin 8", is
how you tell which pin is which. AAFP connector should have a total
of nine pins. You will be making connections to pin 1,3,5,9, and pin 2.
Pin Signal Pin Signal Name
- mic in 1 [Port 1] Left channel 2 Ground - gnd
- mic vcc 3 [Port 1] Right channel 4 PRESENCE# (Dongle present)
- ear r 5 [Port 2] Right channel 6 [Port 1] SENSE_RETURN
7 SENSE_SEND (Jack detection)
- ear l 9 [Port 2] Left channel 10 Port 2] SENSE_RETURN
In the BIOS, you can try setting the Front Panel Support Type to
AC97. I don't know exactly how that part works, or whether there is
a setting in the custom sound control panel in Windows for that selection.
Try the BIOS first.
HTH,

Set the bios for AC97 mode, then download the following and look at page 21
http://www.formfactors.org/developer/specs/A2928604-005.pdf
And study here too!!!!!!!!!

The way it works is if its wired correctly, when you plug in your headset or
microphone, it should disable the rear PC speakers, then when you unplug, the
rear speakers return to normal.
mic in = Pin 1
gnd = Pin 2
mic vcc = Pin 3
ear r = Pin 5
line r = Pin 6
ear l = Pin 9
line l = Pin 10
Also when done, reinstall the audio software for the SupremeFX II card either
off of the support CD or get the latest from Asus.
I have heard that someone that was having problems had to reinstall the
drivers after making some changes cause windows wouldnt detect some wiring
changes.
Paul
Based on your answer, I can see my interpretation of the wire names
was incorrect. Normally, the cable should have "ret-r" and "ret-l",
which are the AC'97 return signals from ear-r and ear-l. So perhaps
they've changed those two signal names to something less meaningful.
I stand by my original answer, including wiring table. The wiring only
needs five wires in this case. I'll go though the connector cases,
but the OP can ignore what follows.
*******
There are three header connector configurations.
The original AC'97 header. This predates the introduction of
HDAudio. (The OP's Supreme FX II is an HDaudio device.)
http://www.formfactors.org/developer/specs/fpio_design_guideline.pdf (page 20)
AUD_MIC AUD_GND
AUD_MIC_BIAS AUD_VCC (+5V filtered)
AUD_FPOUT_R AUD_RET_R
HP_ON
AUD_FPOUT_L AUD_RET_L
That standard supports muting as follows. The CODEC sends a line level
signal to FPOUT_R and FPOUT_L. The signal enters the front panel connector. A
side contact switch, sends the audio signal back and it gets connected
to RET_R and RET_L. If no headphone plug is installed in the front jack,
then the signal flows back via RET_R and RET_L. RET_R and RET_L are hooked
directly to the computer rear green colored "Line_out" jack. The muting
function is thus, implemented with switches in the headphone hack on the
front of the computer. When you plug in headphones, the switches open,
killing the signal on the rear green Line_out jack. This allows the headphones
to mute the function of the front speakers, wired to the green Line_out
jack on the back of the computer.
When Intel did their HDaudio spec, not only did they invent a new pinout
for the 2x5 connector for HDAudio, they also redefined the AC'97 header.
(Which is, strictly speaking, a stupid thing to do.) That basically
makes it less compatible, with all possible applications of AC'97 that
case manufacturers may have chosen to use in the past.
First of all, one difference with the HDaudio codec chip, is it has more channels
on it. The "ret-r" and "ret-l" muting concept is no longer required. Muting
can be electronic, as sensed by the codec chip, rather than relying on switches
in the headphone jack. Thus, the basic "analog" signals of interest, look
like this. These signals exist on both the HDAudio pinout, and also
the HDAudio redefinition of AC'97. So you cannot go wrong, by hooking
analog wiring to these pins.
AUD_MIC AUD_GND
AUD_MIC_BIAS ---
AUD_FPOUT_R ---
---
AUD+FPOUT_L ---
This is the HDAudio pin definition. Intel renamed the MIC and Headphone (FPOUT)
signals, to "Port", to emphasize the fact that the connections are retaskable.
You can plug a headphone into a mic jack. Or a mic into a headphone jack. The
codec senses this, the driver software asks "did you plug in headphones?" in
a popup box. The user "retasks" the jack as required, by answering the
questions.
PORT1L (MIC) GND (AUD_GND)
PORT1R (MIC_BIAS) PRESENCE#
PORT2R (HEADPHONE_R) SENSE1_RETURN
SENSE_SEND
PORT2L (HEADPHONE_L) SENSE2_RETURN
The four remaining signals include PRESENCE#, a signal you ground, to indicate
you're providing SENSE info. The SENSE send and return signals, are part
of the mechanism the front (true HDAudio) panel jacks would provide.
Very few jacks have the isolated side contacts to connect to SENSE send and
return. HDAudio chips rely on impedance sensing, to detect the presence of
a new connection. The SENSE send and return, are tied into a resistor tree,
which in turn feeds an ADC converter at the CODEC. The CODEC gets a four
bit code from the ADC, which tells it which jacks isolated switch has closed
or opened. This complex mechanism is used, to reduce the number of pins
on the side of the Codec chip.
So, since HDaudio has redefined the RET_R and RET_L pins, you should
not be using them any more, for the redefined AC'97.
For an HDAudio motherboard which mentions support for AC'97, these are
the signals you can depend on. This is the picture you should find in
a motherboard manual. The reason the other pins are dashed, is because
a user should not wire all the AC'97 wires from the front panel, to the
old places they used to go. Only five wires are needed. You don't want
to upset the SENSE function, by wiring audio RET_R and RET_L to them.
AUD_MIC AUD_GND
AUD_MIC_BIAS ---
AUD_FPOUT_R ---
---
AUD+FPOUT_L ---
*******
So that leaves three header definitions.
Original AC'97 motherboard. Wire up seven wires total. Remove the two
blue jumpers <--> that ship from the factory, then wire it up. HPON
is not used. AUD_VCC is not used. That leaves seven wires. If you see
mention of jumpers in the user manual, and "ret_r" or the like,
then that tells you the motherboard is likely a pure, old style,
AC'97 setup.
AUD_MIC X X AUD_GND
AUD_MIC_BIAS X X AUD_VCC (+5V filtered)
AUD_FPOUT_R X<-->X AUD_RET_R
HP_ON X
AUD_FPOUT_L X<-->X AUD_RET_L
The OPs case is HDAudio. You could use a real HDAudio wire harness,
complete with isolated side contact switches, and wire all pins. Very few
computer cases support this. And even a computer case with "HDaudio"
stamped on the connector, may not in fact have anything wired to
SENSE/PRESENCE and so on. A real HDAudio would require nine wires,
but you're not likely to see that in a real computer case. HdAudio
motherboards do not have any blue jumpers factory installed, and
no jumpers are ever required.
PORT1L (MIC) GND (AUD_GND)
PORT1R (MIC_BIAS) PRESENCE#
PORT2R (HEADPHONE_R) SENSE1_RETURN
SENSE_SEND
PORT2L (HEADPHONE_L) SENSE2_RETURN
Most people will be using the AC'97 variant of HDAudio, which is this.
Wire up five wires. As I suggested to the OP in my answer. Since
an HDAudio codec has enough channels to not need a mute function,
there is no longer a need for return wires. (The Line_out on the
rear of the computer, has its own audio channels.) And they would
only conflict with the sense function in any case. Again, no need
to fit jumpers to this, if removing the front panel wiring later.

HTH,

GMAN
If you do the last wiring diagram you list with 5 wires, the rear speakers
will not shut off when a headset is inserted in the front jack. If his case
has the extra return wires why would you suggest he not wire the in the proper
way?
If you notice, they kept the same pinouts for HD Audio as AC'97 to avoid
header issues on cases
So the pins i specified in my post still stands even if the OP is leaving HD
Audio on in the bios, and what i stated still stands that he should reinstall
the drivers after the changes.
Paul
They will, because impedance sensing is used to determine when things are
plugged and unplugged. The mute function is electronic and implemented in
software. Some HDaudio even have software support for cloning, as there
are some users who desire headphone drive and lineout drive at the same
time (with the same stream content). Because the function is implemented
in software, all of that is possible. When you have bidirectional widgets
on all ports, the only limitation is that imposed by the software. Since
there is jack retasking, a user can even plug a headphone into the mic
port, and a microphone into the headphone port. (The software design
intent seems to be, to duplicate how AC'97 works, presumably so
customers will not get confused. For example, I don't see an option
to drive outputs on all ports at the same time, in software.)

The "real AC'97" case was done with switches. And blue jumpers were
provided, as a factory default for the header, to take the place of the
switches, and ensure the signals made it to line_out when a user had no
wiring on it. On AC'97 codecs, there were fewer ports, so one port was
stretched to perform two functions.

While an AC'97 computer case with a fixed 2x5 assembly (not separate
wires) can be connected to an HDaudio header, it means the audio return
signals from the front jacks, are now wired to the SENSE resistor
tree. Since the port output impedance is somewhere between 1 and
32 ohms, that tends to override the sense resistors much higher
value. There likely isn't a lot of side effects on the audio signal
itself. I presume the reason the HDaudio codec doesn't go nuts, is
because the ADC on the resistor trees is turned off. I don't know
all the tiny details, as in, how does a BIOS setting for the header,
change the registers in the HDaudio codec. Is the header state
(HDaudio mode or AC'97 mode) passed in a BIOS table ? Or is a register
in the HDaudio written such that the resistor tree sensing is turned off,
and the chip is doing impedance sensing only ? The fact there is a
BIOS setting for this, implies some form of communications or control.
The only thing I see that might need changing, is turning off
the SENSE function, when the BIOS is set to [AC'97 header mode].
If you have loose wires for your front panel wiring, it is better to
just not connect the RET_R and RET_L wires, and not end up connecting
them to SENSE pins. But if you have no choice, I don't see the harm if you
do happen to connect them. It just doesn't do anything. So you
can connect them if you want (RET_R, RET_L on HDAudio). It means
your audio outputs to the headphone, are driving a tiny
resistive load, which they can do with no problem. They're
typically rated to drive a 32 ohm load.
The problem with HDaudio documentation, is it is written for
software people, and there is no way to relate what is done,
to registers. It is all hidden from view.
