[VIA] MSI KT4V-L Front side Audio Connections to mainboard

I have an MSI KT4V-L mainboard and i want to connect audio to the board from the front of the case. The manual is really sketchy as to what the connectors are. The pinout in the manual says P5 Right channel audio signal to front panel, P6 Right channel audio signal return from front panel.....and so on for the left side. Also is P2 Ground used by analog audio circuits. My question is, is P5 the (+) side of the channel and P6 the (-) side of the channel? Or is P5 the Line Out and P6 the Line In and P2 a common ground for all the audio? Any help is really appreciated

Hi,
The front panel audio socket has a "send" and "return" line for the left and right channels. The green socket on the front panel has special switching connections inside it. Normally, the send and return lines of each channel are connected together. The signal returns to the mobo, and is connected to the rear audio out socket. If you plug something into the front socket, the switches open and disconnect the return signal, effectively cutting off the rear output signal. If the front panel socket isn't connected at all, a pair of jumpers have to be fitted between pins 5-6 and 9-10 to connect the signals to the rear socket.
When experimenting, avoid connecting to pins 3 & 4, as these might have some voltage on them.
Cheers

Need help for front pannel audio connection

Hi everyone,
I've a msi p4m800 board. Its doing good but i want to connect the front pannel audio connection but am a beginner and don't really know about the pin assignment.
There are 5 small cables for audio marked as:
spkL
spkR
Mic
Mic power
Gnd.
I know to connect these in 10 pin JAUD1 slot but how? Am much confused and I really want to connect front pannel audio.
ps: is there any possibility to damange the system if i connect these pins wrongly?
Thanks in advance
Regards

Please refer to your manual, there should be a page to teach you on how to connect the front panel audio.

MSI P965 Platinum - Front Panel Audio u/s

Finally after managing to get XP Pro SP1 CD to install, I have a stable system, and thanks to those whom freely gave advice.
But we hit the next issue with this motherboard, the front panel audio.
Firstly the Realtek detection software doesn't detect anything plugged into the front panel.
Connected the cables as follows from my Coolermaster Stacker case;
mobo = case wires/colour
pin1 aud-mic = mic-in - yellow
pin2 aug-gnd = gnd - black
pin3 aud-mc-bas = mic-pwr - red
pin4 aud-vcc = empty
pin5 aud-fpout-R = R out - green
pin6 aud-ret-R = R ret - green
pin7 hp-on = empty
pin8 key
pin9 aud-fpout-L = L out - white
pin0 aud-ret-L = L ret - white
The above pin out gives nothing at all, but audio from rear ports on the computer motherboard is fine.
I also tried the following,
where the microphone wires were left disconnected, therefore just the speakers plugged into the front panel audio header
mobo = case wires/colour
pin1 aud-mic =
pin2 aug-gnd = gnd - black
pin3 aud-mc-bas =
pin4 aud-vcc = empty
pin5 aud-fpout-R = R out - green
pin6 aud-ret-R = R ret - green
pin7 hp-on = empty
pin8 key
pin9 aud-fpout-L = L out - white
pin0 aud-ret-L = L ret - white
The above still gave me no audio out from the front panel.
Intrestingly if I leave the front panel audio header blank, I still get rear audio fine, where I would have expected to have put jumpers across the L and R outputs as is the norm.
I have removed the front panel from the computer to ensure that the wires terminate OK, and have not been pulled out/off.
Have I plugged in the wires correctly?
Is there some hidden setting that I have missed, I admit that I do not like the Realtek audio software?
I cannot find any way to boost the microphone input since Realtek audio software has been installed.
One day case/mobo manufactures will use a standard for the front panel headers and front panel audio headers, and we will have a simple single plug to insert, rather than a group of single fiddly connectors that have to be attached to a header that was at the last minute attached to the motherboard as far away from the front of the case, and in the darkest most fiddle corner.
Oh well......
Cheers

AaronYuri - you're are so right there my friend. I just pity Joe User whom might attempt such a move themselves.
In the end my entire issue was software related, and that has to be blamed on Realteks software, far too many options approached from far too many different angles. Audio is really simple, plug your cables in, and it should just work, certainly in the simple case of 2-1 speakers and a microphone. Why exactly it took a couple of hours to figure out how to get the front panel microphone to be seen in the first place, let alone any signal, is beyond me.
So my cables were all connected correctly as per the MSI manual, confirmed by my Abit manual and other post here and on other forums.
In the Realtek MSI audio software, on the I/O Audio tab, connector settings, I had to select 'disable front panel jack detection' and 'mute rear panel output when front headphones plugged in'. The other option here 'enable auto pop up...' is unchecked.
After this the Realtek software mentioned something about a new profile had been set up?
I then went to Windows Control Panel, Sounds and Audio devices, and selected the voice tab, on this page I selected 'mic IN at front panel [pink]' from the drop down list for Voice Recording'. Proceeded to 'test hardware' and the microphone is now working. This option to select the input in the drop down list was not available before.
All a bit of POKE and HOPE.
But we seem to be there.

P35 Neo2 front panel audio connections

Appologies if this has been covered elsewhere [I did search honest ]
I'm having trouble getting the case front headphone jack to work with my MSI P35 Neo2 motherboard. The connections from the case are;-
Speaker Right
Speaker Left
Speaker Right Rtn
Speaker Left Rtn
Mic IN
Mic Bias
Gnd
...and the motherboard JAUD1 connections are-
1 Mic-L
2 Gnd
3 Mic-R
4 Presence#
5 Line Out R
6 Mic-JD
7 Front JD
8 NC
9 Line Out L
10 Line Out JD
Since the manual states these conections are compliant with the Intel front Panel and seems to mention HD audio, am I wasting my time? Obviously I'd like the rear speakers to be disabled when I connect the headphones at the front.
Any clues?
Cheers

Have you checked in realtek's audio manager and see if you could switch between front and rear individually?
Yes I did have a dig around with this because it senses when additional speakers etc are connect at the back. I cannot get the audio manager to acknowledge there is a front connect (with or without anything connected)

MSI K9N PLATINUM FRONT PANEL AUDIO

Hi everybody
I recently mounted an MSI K9N Platinum mainboard. When connecting front panel audio from case connectors on JAUD1, case connectors are marked as follows:
MIC POWER
MIC IN
GROUND
R-RET
L-RET
R-OUT
L-OUT
which does not match with those written on mainboard user manual for JAUD1 which are FRO PIN 1 TO 9 as follows:
PORT1L
GROUND
PORT 1R
PRESENCE
PORT 2R
SENSE1_RETURN
SENSE_SEND
KEY
PORT2L
SENSE2_RETURN
.I´ve tried to connect it on many combinations but yet it is not working.
Could someone tell me the right way to do it?
Thanks in advance.

I think you better ask this question to the manufacturer of the frontpanel stuff, as I have no clue.

MSI K9A2-CF front panel audio problem

Just rebuilt a computer using the board. Please note, I have not updated the BIOS at all and I am using XP Pro. Anywho, I've tried everything under the sun, so far, aside from previously stated, to get this sucker to work. I have it connected properly, I've installed every audio driver on the motherboard CD. I can't find a setting in the BIOS to turn on front panel audio either. Everything else works fine though. USB's, HD audio connections in the back, etc. The program in windows will detect all inputs except for the front audio in and out.
I'm a bit stumped. Any suggestions?

Quote from: Bas on 17-August-09, 22:22:14
You have to check the wires on the plug, looks like they are wrong or the case-module is broken somewhere.
You have to start checking and measuring with an Ohm-meter.
Remember, neither case front worked. I'm not saying it couldn't be the case, but I'll try to get my hands on an Ohm-meter. Where can I find out what values I'm looking for? I know next to nothing about testing to that extent.
Also, what if it's the motherboard itself? Isn't there somewhere in the bios and/or windows device manager that I can confirm whether or not the device itself is working, or not working, properly?
Thanks for your replies so far.
Mike,
I honestly don't know, but the case only has one audio cable, and the MB only has one audio plug-in for the front panel. I have both drivers installed. The on-board audio plug-in on the rear of the computer works fine. I can get sound, etc, no problem from the rear. Front panel only is not working.

Fronta panel audio connections on KM4M

I got a pc case, and the cables for the front panel audio are: left , right , mic, and ground. The front panel works fine, but the rear ports dont.
What should i do to make it work?
Maybe conect left in with left out and right in with right out?

There must be a return from fron panel audio for rear ports to work
What i did was to solder a piece of solid wire on the jumper, and simply plug in the front panel audio left and right in that wire and it works FINE

Ok. I checked and confirmed... I DID use HD Audio in JAUD1. I only thought I was using AC97... The problem still is:
Front Panel Headphones: Okay.
Front Panel Mic: Not detected at all.
Audio driver version is 6.0.1.6316
Audio Controller HD Audio
Audio Codec: ALC889
DX11
Window 7
Thanks for any further suggestions

Front audio connection on Antec Sonata case

I'm building a new system with K8N Neo Platinum and Antec Sonata. It's more or less working now execpt for bits and pieces here and there. I've been scratching my head over the audio connection all afternoon. The only way I can get audio signal to come out at all is to unplug the front audio line, put the jumpers back and get it out of the back.
Did anybody manage to get the front panel audio connection on the Sonata working at all? The pinout for JAUD1 on page 2-20 of the Neo Platinum manual looks exactly the same as front audio header header pin assignment on page 20 of the Intel Front Panel I/O Connectivity Guide. On the Sonata side, page 4 of the Sonata manual says "If your motherboard supports Intel's standard onboard audio connector, you can plug the 10-pin connector directly onto the board". So far so good. Then the Sonata manual goes on to say on page 5:
8. Rear Right Speaker Out Pin: Connect the RET-R connector to this pin.
9. Reat Left Speaker Out Pin: Connect RET-L connector to this pin.
Note: Your motherboard may not support rear speaker output. In this case, you do not need to connect RET-R and RET-L.
This last part makes no sense at all. According to the Intel document, those RET lines are signals returning from the front panel. They have nothing to do with rear channel, and they must be connected or you won't get anything from the rear line out jack. So what's really going on? Any insight would be greatly appreciated.
Andy

Those 8, 9 and the notes only apply if your motherboard does not have the Intel compatibile IO connectors. So you should ignore those lines.

MSI K8N Diamond - Front Audio Header Mic problem

Hello,
I'm Alex Dias Teixeira from the netherlands
About 3 months ago I assembled my own computer, but yesterday is tried to install my Fronpanel that is on my case. Not without problem.
I connected all pins as said in he manuals, and replaced the two jumpers with the pins, no problems so far. The problem is that my microphone is not working properly in my frontpanel.
Its seems to work but when I record my sound in Windows Soundrecorder I get a flatline but can hear my sound I recorded... in MSNmessenger and Windows Speech hardware test my sound is POOR( bad and soft sound ). I have no clue anymore ... anything is connected properly :(

I hope this is all the info ya'll need and are willing to help me.
Thanks in advance

Check the manual, but if you use the microphone plug-in in the back on the motherboard, you might disable microphone input
to the front case header panel. I believe if you use the microphone in the back, it disables microphone input from the front. Also be sure to check the multimedia/sound settings near the clock to make sure you don't have anything muted in advanced tabs found.

Connecting the chassis-mounted front panel audio I/O module to the X-Fi Extreme Mu

Hello to everybody.
Many pc chassis provide two audio connectors on the front side, usually for the headphones with microphone.
I need to know if I can connect the chassis-mounted front panel audio I/O module to the Sound Blaster X-Fi Extreme Music.
I saw that the X-Fi Extreme Music has the internal connector (named AD_EXT) to connect . Is there a pin mapping of the AD_EXT connector? Is it possible to connect the chassis-mounted front panel I/O module cable to the proper pin of the AD_EXT connector?
Thank you.

Hi and thank you for your response.
Unfortunatelly I actually haven't got a X-Fi card, because I need to know if I can connect the chassis-mounted front panel audio I/O module to the card before buying it.
For this reason I don't know what is the J you're talking about. Is it an internal connector avaiable in the X-Fi Extreme Music card? Can I use this J to connect the chassis-mounted front panel audio I/O module to the card?
Thank you.

What case do you have? If it is an older case with AC97 audio then you would need to purchase something like one of these: http://www.amazon.com/s/?ie=UTF8&keywords=hd+audio+front+panel&tag=googhydr-20&index=electronics&hvadid=54539991636&hvpos=1t2&hvexid=&hvnetw=g&hvrand=11069445173547096755&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_2w99a9udvo_b
I simply got me an inexpensive case for my last upgrade since I also needed front panel USB 3 and up to date card reader in addition to the HD audio. My case was only $10 more (free shipping at time of purchase ) than the front panel module I needed so I got the new case you see in my signature instead.
