I can confirm the CMI8738PCIAudioDriver.kext works using the HT Omega Striker 7.1 on 10.6.5 retail DVD install with C-Media CMI8770 chipset.  Only tested "Front" output on the PCI bracket (not the Front Panel output header) but I'm stoked... even 2 channels of output is infinitesimally better than 0 channels.

Two thumbs up!

any hope for CMI8788?

I pulled a diamond xtreme 7.1 pci soundcard from a discarded pc and it has the 8768 chipset. used the kext for 64 bit and at first i tried the E/E folder, nothing so i put it l/s/e repaired permissions and now works on 10.66 64 bit. My onboard alc1200 on my p5q pro (dsdt injected, alc1200legacy and pearl script patched 10.66 applehda) is also still working.

that soundcard is nice especially for free!!

I think I should say my experience in order for others to see as I did in this forum that this chip is working (well, semi-working).

First of all I disabled the Azalia audio codec in BIOS (I have a Gigabyte Z68A-D3H-B3).

After many kernel panics and restoring my installation, what I did was to download from shagui's post  this file, having to install it both in Extra/Extensions and in System/Library/Extensions and then running Kext Utility 2.3.2 so as to recreate caches...

Running 10.6.8 snow leopard 64bit

Using the shagui posted Codec in 10.7 on a 8786 based PCI card. SPDIF 2 Channel output and analog 2ch working. Installed using Ktext Utility. Thanks!

I'm on it.
The only problem is, I can't find ANY reference about the chip's registers, and I saw somewhere that this data is under a Non Disclosure Agreement... I'll see. (If you can find this very document -not the usual technical sheet about the chip, it contains almost no information- you're welcome)
