K8V SE Deluxe Audio Question
It was my understanding that the rear audio would cease to function if the
front panel audio connector was in use ie. a headphone was plugged in(I'm using an Antec Sonata case). I can get around this issue by turning my speakers down(just a generic 2 speaker set), but the A7N8X-E Deluxe I was using previously didn't behave in this fashion. Just curious. TIA for any insight. |

I ripped the connector assembly out of my Sonata when I got it, so it is sitting here in front of me. The front panel connector assembly has a USB, a Firewire, and an audio cable. The audio cable ends in a 2x5 connector, with one pin blocked, which is the normal 9 pin FP_AUDIO pattern. But, only 7 wires are installed in the plastic shroud, and little wires also come out of the shroud, for situations where the standard 2x5 is not sufficient. (Sonata) --- K8V SE FP_AUDIO Header -- (Sonata) green ret_l BLINE_OUT_L x x Line out_L orange fpout_L (none) x NC (none) black ret_r BLINE_OUT_R x x Line out_R yellow fpout_R (none) +5VA x x MICPWR brown MIC_bias grey aud_gnd AGND x x MIC2 red MIC The Sonata wiring is correct. I even took my ohmmeter, and measured from ret_l to fpout_l, and when a plug is inserted in the lime green jack, the connection between those two wires goes open circuit. That is the mute function. I checked the right channel as well. (My ohmmeter has sewing needles for tips, so it is easy to plug them into the wires.) The jacks on the Sonata circuit board are the appropriate 5 pin, interrupting kind. In terms of how the signal travels, it starts at Line_out_L, goes up the orange wire (fpout_l), to the switch in the lime green jack on the Sonata front panel, then back down the ret_l wire, where it goes into BLINE_OUT_L and across the motherboard to the lime green Lineout jack on the back of your computer case. For the mute to work, the headphone has to be plugged in far enough to cause the contacts to open in the jack. I don't know what to suggest, because plugging the 2x5 connector should give instant and correct wiring, as far as I can determine here. HTH, Paul |
