DFI Lanpary NF4 SPD/IF in Windows 7/Vista

. Tuesday, August 18, 2009

I’m still happen to be one of these old fools who think investing hefty amount of money should help to last your pc longer times without updates (given smart choices of course) and the motherboard in title is still powering my main pc running o/ced x2 3800 at humble (nowadays) 2.4Ghz. Not much, but still plenty for day to day stuff, even some occasional game or two.

My Windows XP was getting old and decided to put a new OS – its was long overdue.
Windows 7 Ultimate is the natural choice, since I got access to MSDN version of current RTM – basically same one you’d buy at store then it’s official out.

Install went without any glitches, with only a couple small driver issues, and one of them was Windows 7 recognized my onboard sound as Nvidia audio codec – given my chipset it Nvidia nForce4 – sound worked out of the box and most people won't even bother ever messing with it, except it was limited only to analog input/output and only stereo.

I use my creative card to process my day to day audio like windows sounds etc, but since it’s lacking real digital output – SPD/IF – I use the outboard sound card to output sound to my home theater.

DFI Lanpary NF4-Ultra used Realtek ALC850 audio codec, and in addition to “Karajan” module (basically slightly isolated 8 channel audio output) got coaxial SDP/IF Input and Output on board, which Windows 7 refused to utilize.

Initially my fight with drivers was fruitless and Realtek High Definition audio didn’t seam to fix the issue…

The fix:

Self Slap on forehead !!! ALC850 isn’t HD Codec, but AC/97 !!!!

Realtek does provide AC/97 for Vista/7 32/64 bit. Just install them, ignore the compatibility warnings and it’ll work fine.

p.s: Don’t bug for links, ffs just Google Realtek
