As @Feartech points out, AppleALC.kext will work fine with your audio codec and motherboard. Just test the Audio ID's one at a time, rebooting and clearing NVRAM in between each test. Likely it will be 1, 2 or 3.

In preference use the NVRAM boot-command section to modify each ID, rather than DeviceProperties.
