The ALC850 is found on AC97 cards, not HDA Intel ones..
HDAPatcher is for the HDA cards only, not AC97. Try a different driver.

Hi, I am wondering whether someone could tell me what I am doing wrong with the onboard sound on my rig.
I am running an AMD Athlon 64 4200+ X2, 4GB OCZ DDR2 800MHz RAM, Geforce 8800GTX video card, and an Asus M2N4 SLI motherboard which has onboard Realtek ALC850 audio, I have done a codec dump using Ubuntu, here is what it tells me:
0-0/0: Realtek ALC850 rev 0
PCI Subsys Vendor: 0x1043
PCI Subsys Device: 0x822c
Revision : 0x00
Compat. Class : 0x00
Subsys. Vendor ID: 0xffff
Subsys. ID : 0xffff
Capabilities :
DAC resolution : 16-bit
ADC resolution : 16-bit
3D enhancement : No 3D Stereo Enhancement
Current setup
Mic gain : +0dB [+0dB]
POP path : pre 3D
Sim. stereo : off
3D enhancement : off
Loudness : off
Mono output : MIX
Mic select : Mic1
ADC/DAC loopback : off
Double rate slots: 7/8
Extended ID : codec=0 rev=2 LDAC SDAC CDAC DSA=0 SPDIF DRA
Extended status : SPCV LDAC SDAC CDAC SPDIF=3/4
SPDIF Control : Consumer PCM Copyright Category=0x22 Generation=1 Rate=48kHz
So I then drag the text file with this information inside it into the AppleHDA Patcher, and it tells me that it is an unrecognized codec... Am I doing something wrong or what, can anyone help me out, as I have been trying for about a week now to get my audio working but nothing I do seems to work...
I started thinking that maybe the onboard audio was fried or something because I use a Soundblaster Audigy in Windows, but I have removed the soundblaster and I am using the onboard sound on my windows installation and it works fine.. I just don't understand why the HDA patcher isn't recognizing my codec dump, I have tried v1.20 and 1.16 neither of them work...
Is there an alternative codec dump that I can use for my Realtek audio, the audio only has three ports on it if that is of any help....
Thanks in advance...
P.S. when I use OSX86Tools to check the dev ID, it says "10de:0059 Rev a2"...
