SPDIF OUTPUT CONNECTOR PINOUT / PIN ASSIGNMENT FOR ASUS A8M2N-LA (NODUSM) MOTHERBOARD (OEM - HEWLITT PACKARD)
After about 8 hours with HP Technical Support, I finally got an answer as to the SPDIF - Out Header on my board. This will come in handy if you are going to hook up onboard sound to your graphics card. (I was installing an MSI N9400GT 512 Low Profile.) Anyway, the pinout is as follows:
[ . ] – Pin #1 Ground
[ . ] – Pin #2 SPDIFOUT
[ . ]— Pin #3 +5V Current
FYI:
I am running Vista Ultimate, I installed an extra gig of RAM, and now this card (can you believe I am upgrading this?) I get a great picture and sound on my TV.

Thank you for posting this! I just bought a video card with HDMI out and it has the 2-pin spdif connector on it. I also have this motherboard and have been searching for what pins to use on the Asus connector. Noone else had a picture or pin-out anywhere I searched. I am going to install the card tonight and now feel confident in installing the connector with this picture and information! Thanks again for the post!
I installed the card last night and it went smooth thanks to this post. If anyone else wants to do this I would recommend using a pair of pliers or a small knife to (very carefully!) pry the white connector off of the motherboard so that the pins will be able to fit snuggly without falling off. Be very careful not to damage the pins or the minute components that are right against the white connector. Make sure that you don't connect anything to the pin 3 as well because that could damage your video card.
Thanks again to Junior Jar for posting this as it saved me lots of trial and error and possibly a fried card.
One more thing to note.....make sure to set the HD audio as the default sound option so that the sound is directed through the spdif connector and then through the hdmi cable through the card. That took me about 10 minutes to figure out as well.
Good luck with the CS degrees!
When I Google "A8M2N-LA pinout", your blog comes up near the top. So, thought I'd add my experience.
I want to replace the A8M2N-LA MB. I assume the USB, audio pinouts and whatnot are standard. But what is not standard is the pinout of the front panel. For another MB, the header pinout will be different. All I have to do is find which wires correspond to each input. After searching the pinout, I found that all I needed to do was look at the silkscreen right on the MB! For my MB, the Front Panel pinout is as follows:
F_PANEL_1 Pinout:
HD_LED (1,3:YEL,BLK)
PWR_LED (2,4:BLU,BLK)
PWR_BTN (6,8:RED,BLK)
RESET (5,7) Not Used
To adapt this to another MB, you may need to put the two wires for each function into a two pin header connector. In my case, I cut the connectors from some old CD audio into two position connectors. After doing this, you can plug each connector into the appropriate position of your new MB.
Hope this helps someone.
Sorry but this is NOT Working.
I have an HP Pavilion a1540n with this motherboard A8M2N-LA with an Asus Geforce 8400GS with SPDIF Input. I have tried EVERY possible method of trying to get this to work. Updated to latest Nvidia Drivers *Setup Digital Audio* option is just not showing up.
If you make a mistake and connect up the +5V line, your PC will simply not start. So you won't destroy your board. However, the internal SPDIF seems to be disabled on this board. Anyone claiming they got it working does not know what they are talking about if they are trying to get Audio over DVI from their cards. They are probably using HDMI video cards. This is FALSE information and should be removed. I am a PC Technician and companies like HP, Dell, etc, order non standard equipment for almost everything they sell. Not only is the PINOUT different, the pin sizes are also 3/4 the size of normal pins to dissuade people from doing exactly this. The SPDIF connection itself is not in a standard location. It should be very near to the RealTek audio chip on the board, instead it is far to the top and in a hard to reach place below the fan. It should NOT be near the output stage. The Internal connection is disabled and no amount of tinkering will help you. Your only option is to connect a Coax RCA to the External jack, splice it and connect it internally to your video card if you must have audio over HDMI. Easier way would be to simply use the COAX and plug it into an an external DAC. Good luck!
Recap: I just tested everything on 5 other PCs, all with ASUS motherboards and internal SPDIF Headers using the standard 2 pin internal SPDIF wiring to Nvidia GTS250, 9400gt, and 8400gs. All of them send Digital audio to the respective video cards. So the only solution is to throw out the Asus board that comes with your Pavilion. The BEST solution of them all is to STOP buying HP and Dell GARBAGE. HP and Dell computers are good when you have an office and all you want to do is Spreadsheets, web surfing, and go home to enjoy a REAL computing experience. The A8M2N-LA (NODUSM) is garbage. So here are my possible solutions.
1) RCA Coax (which does work) back into the case and onto the Video Card's SPDIF input header - This might be too complicated for the average person, but this is what I did, but it's not ideal.
2) Video card with HDMI.
3) RCA Coax directly into your TV digital input, or your AVR digital input.
Make sure you set your TV's input properly. Setting it to DVI/PC will MUTE any sound if you have a Samsung TV.
I notice many people online talking about stuff they don't really know. I can almost GUARANTEE you in all my years around HP, Dell, Acer, etc, these are GARBAGE computers if you want to do any serious business with them. They are good at 1 thing, reliability for a set amount of time, then they die. Expecting more from them is ugly as sin. Good luck to you all and try not to be stupid, just say No Thanks unless you know what you are getting into.
