I've got a Tsunami Capricorn case and the above mentioned mobo. The
guide that comes with the case doesn't state the correct colours on
the front audio and mic cables. There are four cables (Black, Green,
White, Red).
This means that I don't know which lead is which. In the manual for
the mobo, it states the front audio connector on the board as being
set out as follows:
mic2 -- AGND
MICPWR -- +5VA
Line out_R ** BLINE_OUT_R
NC -
Line out_L ** BLINE_OUT_L
The 2 sets of asterisks indicates the jumpers that are on those pins.
I have put every combination of cable on the pins "AGND" & "+5VA" but
I'm not getting any sound from the front connector on the case. Am I
connecting to the wrong pins? Should I remove the jumpers from the
Line Out (R&L) pins, or what?
Thanks for all assistance in advance.
DO NOT put cables on the 5V pin. It is very easy to cause
damage that way.
Not being familiar with your case I can't comment on it's
wiring and connectors but I am familiar with that audio
pinout on your motherboard. You do need to remove the two
jumpers to have front panel audio out. Once those jumpers
are removed you will not have audio-out at the rear of the
motherboard anymore unless your case has audio jacks with
normally-closed switches inside the jacks. Some jacks do
this but others don't.
The black cable is most likely ground. Try putting it
there. Play an audio file on your system, looping so you
have continuous output. Open up the windows mixer so you
have access to the L & R balance slider. Hook your speakers
or headphones, etc, up to the front case output jack but
don't plug the microphone in yet. So, you're creating an
environment in which you'd immediately hear sound if you
connected the cable right. Then plug in one of the other
wires... try the red one as a random first-start.
Plug it into the left or right channel pin where the jumper
was, the "line out" pin of that pair. At that point you
should have audio on your left or right speaker, but you'd
need to use the windows mixer to determine if it's the left
or right channel for that color of wire. Repeat this
process with the next randomly-chosen color. Since you only
have 4 wires, one is ground, one is left-out, one is
right-out, and one is mic2. By process of elimination
you're wanting to get the output right before plugging in
the mic, so system isn't trying to play sound through the
mic which is possible but not a good thing to do, could
damage a mic.
SO with only 4 wires, once you have the left and right
channel output working right, which requires 3 wires, you
only have the one remaining that could possible go to the
mic. Since you only have the 4 wires instead of 6, it isn't
possible to have a return that would enable output to rear
motherboard jacks too, without electrical modifications
which seem beyond your abilities... someone with such
abilities would probably have used a multimeter to check
continuity on the wires and the jack pins but given the
method I described above you shouldn't need to do that.
Just don't hook any wires up to the 5V or Mic-pwr, unless
you are SURE you have higher-grade equipement that needs a
voltage source (typical PC components do not).
