Case front panel audio connectors - Help
I'm putting together 2 PCs, both using a PC Chips Mobo, but each with
a different case. I've connected the front panel usb fine. I'm a bit unsure about the front panel mic and headphone sockets though. Any guidance on which connector goes where would be appreciated! Heres the Mobo usb pin layout; 1. Aud Mic 2. Aud Gnd 3. Aud Mic Bias 4. Aud Vcc 5. Aud FPOut R 6. Aud Ret R 7. HP on 8. Key 9. Aud FPOut L 10. Aud Ret L Pins 5&6 and 9&10 are jumpered. Case 1 Cables (prob the easier of the two - Case front sockets are Mic and headphones); Mic; A. Mic In B. Mic Pwr C. Gnd Headphones; D. Gnd E. L out F. L ret (on a cable from (E) G. R out H. R ret (on a cable from (G) Case 2 Cables (might be a bit trickier - Case front sockets are Mic and headphones); Cable 1 (unknown); I. L in J. L out K. Gnd L. Mic in Cable 2 (unknown); M. R in N. R out O. Gnd P. Mic in A quick summary from someone of which letter connector on each case goes to which number pin on the mobo would help me a lot!! Are there any rules for this? As usual the case instuctions are less than understandable. Thanks Adam |

It's just common sense. You already know which pins on the board do what
and what the connectors do. Just hook em up :-) Left headphones connect to 9 and 10, right to 5 and 6 etc etc. Heres the Mobo usb pin layout; 1. Aud Mic 2. Aud Gnd 3. Aud Mic Bias 4. Aud Vcc 5. Aud FPOut R 6. Aud Ret R 7. HP on 8. Key 9. Aud FPOut L 10. Aud Ret L Pins 5&6 and 9&10 are jumpered. Case 1 Cables (prob the easier of the two - Case front sockets are Mic and headphones); Mic; A. Mic In B. Mic Pwr C. Gnd Headphones; D. Gnd E. L out F. L ret (on a cable from (E) G. R out H. R ret (on a cable from (G) Case 2 Cables (might be a bit trickier - Case front sockets are Mic and headphones); Cable 1 (unknown); I. L in J. L out K. Gnd L. Mic in Cable 2 (unknown); M. R in N. R out O. Gnd P. Mic in A quick summary from someone of which letter connector on each case goes to which number pin on the mobo would help me a lot!! Are there any rules for this?

I'm a bit unsure about the front panel mic and headphone sockets though. Any guidance on which connector goes where would be appreciated! Heres the Mobo usb pin layout; USB? or Audio? These are AUDIO signals, not USB signals. 1. Aud Mic 2. Aud Gnd 3. Aud Mic Bias 4. Aud Vcc 5. Aud FPOut R 6. Aud Ret R 7. HP on 8. Key 9. Aud FPOut L 10. Aud Ret L Pins 5&6 and 9&10 are jumpered.

L ret (on a cable from (E) G. R out H. R ret (on a cable from (G) D -- 2 E -- 5 F -- 6 G -- 9 H -- 10 Yes, I notice you have two on 2. This might cause a small problem .... Case 2 Cables (might be a bit trickier - Case front sockets are Mic and headphones); Cable 1 (unknown); I. L in J. L out K. Gnd L. Mic in I -- 10 J -- 9 (might need to swap .. In and Out to/from what?) K -- 2 L -- 1 Cable 2 (unknown); M. R in N. R out O. Gnd P. Mic in M -- 6 N -- 5 (Again, might need to be swapped.) O -- 2 P -- 1 A quick summary from someone of which letter connector on each case goes to which number pin on the mobo would help me a lot!! Are there any rules for this? As usual the case instuctions are less than understandable. Yah - there's rules. Ground to ground, MIC_BIAS is also MIC_PWR or MIC_Vcc. Left out from motherboard to Left Signal, Left Return to Left In or RP Connector, and same for the right side. Perfectly understandable if you stop and think about it a bit ... RwP |

Hi,

Can I just re-wire the connector so that I have the two gnd wires going to pin 2? Pin 7 is "HP on", presumably headphones on ! I assume the intention of this was to mute the speakers if headphones are plugged in. With the wires provided can I get this to work? (ie would connecting the gnd wire from the HP socket achieve this?) Case 2 Cables (might be a bit trickier - Case front sockets are Mic and headphones); Cable 1 (unknown); I. L in J. L out K. Gnd L.

O -- 2 P -- 1 So in this case (no pun intended), I'll have two connectors on both pins 1 and 2, and nothing connected to pin 3(Mic Bias) or pin 7 (HP on). Are you sure this will work? I don't have two microphone sockets....I'm now even more confused. Yah - there's rules. Ground to ground, MIC_BIAS is also MIC_PWR or MIC_Vcc. Left out from motherboard to Left Signal, Left Return to Left In or RP Connector, and same for the right side. Perfectly understandable if you stop and think about it a bit ... RwP No time to stop and think....are the rules written down anywhere? - I'm particularly interested in the "HP on" pin. Thanks for your help (so far...) Adam |

(ie would connecting the gnd wire from the HP socket achieve this?) No need to. The jack will switch if you wire it right. And if you lose audio completely, then switch the in and out for each side. more snipped So in this case (no pun intended), I'll have two connectors on both pins 1 and 2, and nothing connected to pin 3(Mic Bias) or pin 7 (HP on). Are you sure this will work? I don't have two microphone sockets....I'm now even more confused. That would be confusing, yes. I'm not sure that it's actually listed that way ... There's a good chance that one of the two MIC pins is for MIC_BIAS instead. But with the info given, we can't tell. Yah - there's rules. Ground to ground, MIC_BIAS is also MIC_PWR or MIC_Vcc. Left out from motherboard to Left Signal, Left Return to Left In or RP Connector, and same for the right side. Perfectly understandable if you stop and think about it a bit .... RwP No time to stop and think....are the rules written down anywhere? - I'm particularly interested in the "HP on" pin. You'll have to check what the MB manufacturer means for that. RwP |

(in each of the shielded cables, if that is what you have). See the description. 5 and 6 are currently shorted, so 5 is audio from the motherboard, 6 is the RETURN that goes to the BACK jack. So that a switching jack can disable the rear jack ... That's not a "ground" return, but a "signal back out" return. Otherwise, there's be NO audio with 5 and 6 shorted (and 9 and 10) .... RwP |

What I am saying is that there are 6 signals that connect to that connector, You will probably be using shielded dual-conductor wire, which makes 3 cables, 3 grounds. Otherwise, there's be NO audio with 5 and 6 shorted (and 9 and 10) ... RwP |
