front panel sound.. please help

[krishnenduk]

hi,

My motherboard is MSI 915G Combo. It has CMEDIA AZALIA sound chip which supports multistreaming functionality. The sound output can be taken from frontpanel as well as backpanel audio connectors. But the frontpanel connectors are provided as pins in this motherboard. I got a Mercury KM08 ATX cabinet which has frontpanel ports. But how can I connect the pins?? The cabinet have wires to connect the pins to frontpanel.

There are 7 wires for front panel connectors in cabinet which are


1) Line out FR
2) Line out RR
3) Line out FL
4) Line out RL
5) MIC IN(R)
6) GND
7) MIC Power (L)


In my mobos manual the front pannel connection design is given as,


Pin1 - PORT 1L - Analog port 1-left channel
Pin2 - GND - Ground
Pin3 - PORT 1R - Analog port 1- Right channel
Pin4 - PRESENCE# - Active low signal
Pin5 - PORT 2R - Analog Port 2-Right Channel
Pin6 - SENSE1_RETIRN - jack detection return from front pannel jack1
Pin7 - SENSE_SEND - jack detection sense line
Pin8 - KEY - connector key
Pin9 - PORT 2L - Analog Port2-left channel
Pin10 - SENSE2_RETIRN - jack detection return from front pannel jack2




Please help me to connect the pins to the frontpanel connectors of the cabinet!!!!

I would just experement with it. I doubt if it would hurt anything.
My Guess is
1)Line out FR = pin3
2)Line out RR = pin5
3)Line out FL = pin1
4)Line out RL = pin9
5)Mic IN(R) = Not sure id skip it
6) GND = Pin2
7) Mice Power Id skip that one also unless the manual helps with this.

your best bet is to try and find someone who has the same motherboard/case combo and has wired them successfully. front panel audio can be devilishly tricky. in fact i still haven't figured mine out.

i found this

i visited the msi faq...

but in my BIOS i can change the sound card mode to ac97....

after changing that can i connect the mic connections?? if yes how??

msi says that the pins are compatible with intel front panel connection guide.. it says that


Pin Signal Name Description
1 AUD_MIC Front Panel Microphone input signal
2 AUD_GND Ground used by Analog Audio Circuits
3 AUD_MIC_BIAS Microphone Power
4 AUD_VCC Filtered +5 V used by Analog Audio Circuits
5 AUD_FPOUT_R Right Channel Audio signal to Front Panel
6 AUD_RET_R Right Channel Audio signal Return from Front Panel
7 HP_ON RSVD for future use to control Headphone Amplifier
8 KEY No Pin
9 AUD_FPOUT_L Left Channel Audio signal to Front Panel
10 AUD_RET_L Left Channel Audio signal Return from Front Panel


is this may help????

I just dont know why MSI dosnt just say mic>I always use MSI and Ive never ran into this problem before.But i never use front panle. I dont know where to go from here If it was me I would just try a few different pins till i got the mic working.

 

[krishnenduk]

i tried but....

i have done many trial and error experiments....

i said earlier my mobo supports multistreaming functionality..

which means we can use 2 different mic or 2 different sound outputs
from front panel and back panel simultaneosly by software adjustment.

this makes things more complicated.. so i gave up trial and error methods and posted this query in forum

see if you can find a PDF file of another MSI motherboard. Perhaps mine would be the same. I'd look for you, but I'm at home and my computer's in my dorm.
