Hi,I'mtrying to connect up the audio pins from the front case panel ( I have no identifying lables or documentation for this case) tothe adio header pins on a GA-MA790FXT-UD5P Mother board.
The case has atotal of 8 pins and lable as such MIC-IN
MIC-BIAS
L-IN
L-OUT
R-IN
R-OUT
AND 2 X GRND
all plugs are individual
The M/B plugs are lable as such for HD (not sure my case supports this) or for AC'97
1) MIC2-L MIC
2)GRND GRND
3)MIC2_R MIC POWER
4)ACZ_DET NC
5)LINE2-R LINE OUT-(R)
6)GND NC
7)FAUDIO_JD NC
8)NO PIN NO PIN
9)LINE2_L LINE-OUT (L)
10)GND NC
Could some help me match up the plugs with the mobo pins
??? TIA mortda

Yeah you will need to use the AC97 config
or AC'97
MIC = MIC IN
GRND = ground
MIC POWER = mic bias
NC = another of the grounds possibly
LINE OUT R = right line out
NC = right line in
NC
NO PIN
LINE OUT L = left out
NC = left line in
Give that a try :) you may have to swap and change the ground connections

Is that a typo there!
NC is Not connected ;)
You got your right line in, your left line out, in out shake it all about You do the hokey cokey ;D
Ok just got back from a looong party :o

Nope have come across it before, not a typo, you need line in and out for ac97

Ignore the Intel HD part and look at the "For AC-97 Front Panel Audio" bit, that explains it better :)

Question: Day kind!
It is rather grateful to you for the offer " to try to use other microphone "
Therefore, for a choice of a microphone, inform:
1. What pressure (voltage) and allowable current For AC ' 97 Front Panel Audio Pin No.3 (MIC Power).
2. What size noise (pulsations) on Pin No.3 can be in a strip 50гц-10000гц.
3. What entrance resistance on Pin No.1 (MIC) in килоомах.
4. What constant pressure (voltage) can be sent on Pin No.1 (MIC) in вольтах without infringement of reception of a signal c a microphone.
5. What comprehensible level of a signal from a microphone is sufficient for qualitative record of a signal.
If you will not complicate, explain For HD Front Panel:
5. For what are intended Pin No.4 and Pin No.7 and what parameters of signals on these Pins can be.

Answer: Good afternoon!

Most likely, you need to try to use other microphone, probably, your microphone is incompatible or intended for other use.
