p5b audio front panel connector question

i am using a p5b deluxe in a zalman hd160 case.
i don't don't know how to connect the front panel connectors to the
motherboard.
here is what i have.

the zalman hd160 has the following connectors:
mic-pwr, mic-in
ground
l-out and r-out
ret-l and ret-r

the p5b can be configured two ways - one is hd compliant and the other is
legacy ac97.

the hd compliant pins are:
port 1 l and port 1 r
port 2 l and port 2 r
ground
sense 1 return and sense2 return
sense send and presence

the legacy ac97 pins are:
line out l and line out r
micpwr and mic2
agnd

my guess is that i use the legacy ac97 and connect the two zalman mic
connectors to the 2 p5b mic pins
the ground to the ground
and the l-out and r-out to the p5b line out l and line out r

am i correct.
a pain in the neck to get to thge connectors in the case so i would like to
do it once.

thanks

 

Yes, that seems reasonable.

On the Zalman microphone jack, mic-in should be Tip,
mic-pwr is Ring, ground is Sleeve on the 1/8" jack.
On the headphone output, l-out should be Tip,
r-out is Ring, ground is again the Sleeve.
Tip, Ring, and Sleeve are the names of the three
contacts on a 1/8" connector.

The ret-l and ret-r don't do anything in this case, because
the HDaudio nature of the sound solution, does not require
returning any signals to drive the green jack on the back of the
computer. The HDaudio chip has enough output drivers, that the
green jack is driven directly by the HDaudio chip. And that
is why the ret-l and ret-r are not used.

I'm still waiting to see a computer case with HDaudio labelled
wiring.

Re: "The ret-l and ret-r don't do anything in this case, because

That may be true, but another purpose of this wiring configuration is to
have the speakers cut off when the headphones are plugged in.

 

With a separate port for the headphone signal and for the
green Lineout on the back of the motherboard, the headphone
mute function can be implemented in software. (Having a working
jack sense function helps.) The nice thing about using software,
is there doesn't have to be any static as the jack is inserted
or removed.

Which they should have done in the first place for AC'97
That jumper scheme and ret-l/ret-r wiring was a pain.

Thanks for the help.

maybe someday motherboard and case audio will become standarized.
