I was wondering if anybody has had any luck getting sound on a msi k9a2-cf (alc888) in snow leopard. I have been trying for days without success. I have searched all over and I can't find any threads about anyone trying to get audio in snow leopard on the k9a2-cf. I have attempted patching applehda using the leopard version, patching dsdt, using the azalia kext, and using legacyhda. I got sound with voodoohda but it is so extremely distorted that it is unusable even before sleep. Everything else is working perfect if I could just get sound. If anyone has a solution or even suggestions I would highly appreciate it.

OS:Snow Leopard 10.6.2 Modbin Kernel
CPU:AMD Phenom x4 9850 Black Edition
MB:MSI K9A2-CF

Audio:Realtek ALC888

Field Note #3 @wastez 2011-09-01

Forget trying to get it working with AppleHDA.
I never read that someone with a amd got it working.

So the only way to get it working is to install VoodooHDA or Azalia kext.

Here is a VoodooHDA to get it working: k exts.com/downloads.php?do=file&id=423

Don´t forget to delete the AppleHDA, also any enabler or something like that.

@ BJ_14
There is no way to install Lion on a amd in the moment because there is no kernel which is working.

Field Note #6 @silverkid 2011-09-02 ↳ Re: @akimoa
@akimoaWill not work !:-d

Well, it's working right now on my 4 year old AMD pc For me, its a lot better than the latest voodoohda because it doesn't have that annoying delay before each sound.

Field Note #7 @akimoa 2011-09-02

so u might got lucky and u are on a nvidia chipset board (on Ati chipsets we are doomed)

and the delay infront of the sound refers to wrong bootloader /kernel combination

since it is realated to the FSB detection wich was just corrected couple days ago

Field Note #8 @silverkid 2011-09-02

wow, i'm impressed : i really do have an nforce chipset, so i guess that's why. thanks about the info on the delay too, my only fix was to use that pointless boom app. i'll give voodooohda another try, because i don't really like the sound assertion errors i get with applehda

Field Note #9 @akimoa 2011-09-03

if it is really the problem i was thinking
update your bootloader to the latest version and go for anvs Latest legacy kernel V8 R2 (cl .ly/3l3t163U1h2p3O2K110x) and the lags should be gone also check if AMC C1E is disabled in bios

Field Note #10 @silverkid 2011-09-03

ya i did that yesterday and i was happy because it didnt have that delay anymore. But this morning it came back... i think it had something to do with the fact that yesterday i unloaded applehda, and loaded voodoohda without restarting. Once i saw that the delay was gone i removed all the enablers and the applehda and switched to voodoohda then rebuilded caches, etc. Then this morning, delay again... Oh and about that option in the bios, i have a locked oem bios, i can only turn on or off a couple of things and AMC C1E is not one of them
