BIG Thx Krazubu !!!

This driver work for CMI8770 chip but on Audio MIDI Setup can't select Output type(Analog or Digital).
Krazubu plz can you fix this - if you can, All of us will have passthrough.

This is what i mean:

And information is from here.

Just make it possible to switch uotput bro. You are great, but if it can't done just tell us to stop hopping.

And one more thing: Can you compile x64 version of this driver. This will give us support for SnowLeo! Thanks Again for your time!

I used iAtkos v7 with the iDeneb combo update to 10.5.8 in combo with the zip package.
Installed using install.sh and works perfectly with my Auzentech Xplosion (CMI8770)!

HELP FOR SNOW LEOPARD???

.. PLEASEEE!!!

Sep 10 2009, 03:58 AM

I actually have 10.5.8 presently installed on an EFIX machine I built. It is an intel Mac so the M-Audio Delta 192 PCI souncard does not work but I did buy an HT Omega Claro + Plus and I think it has the C-Media CMI8788 chipset and is works great on my other computer. This build is striclty for my recording studio and all I really need it to do is process the outgoing audio. I am new and haven't a clue what a kext is but I did download the driver Krazubu posted to this thread and I want to give it a try. ANY help is welcomed! THANKS

i'm a bit of a noob when it comes to os x and ideneb, however i have managed to get it to boot up and work. the only thing left to do is to get my audio to work...

i have the c-media 8738 pci audio card and i have tried doing some of the things said on the thread but doesn't work. i have an msi p7n diamond board. please could someone write a detailed step by step guide for me, i would appreciate it very much

thanks in advance

oh and i'm using 10.5.5

No luck for me either (I'm on Snow Leopard 10.6.1 64-bit). I have a CMI 8770 PCI sound card, but the 8738 drivers always worked for me, or they did back in Leopard. When I started up the computer in verbose mode, I got this error:

QUOTE

Kext CMI8738PCIAudioDriver failed to load (0xdc000016).

I then used kextlibs to examine the kext, which came up with this:

QUOTE

For x86_64:
com.apple.iokit.IOAudioFamily = 1.7f16
com.apple.iokit.IOPCIFamily = 2.6

For i386:
com.apple.iokit.IOAudioFamily = 1.7f16

com.apple.kpi.iokit = 10.0

For ppc:
com.apple.kpi.iokit = 10.0
com.apple.kpi.libkern = 10.0

192 symbols not found in any library kext.

Kextutil came up with this:

Check library declarations for your kext with kextlibs(8).

Not exactly sure what it means, but could this help with the kext at all?
Thanks for posting that though!

hi, under 421build CMI 8738 works fine with that kexts. But under 432 - nope =(

any ideas?

Which kext did you try? And are you in 64-bit mode or 32-bit mode?

I'm using this kext http://www.insanelymac.com/forum/index.php...st&id=28938
Tried with 64 & 32bit modes - no results.

Hm, you said it worked under 421 build? Was that an older version of Snow Leopard? I'm getting what I posted earlier, so maybe that kext just wasn't compiled correctly?

Yes, right. That was an early build before the retail. And it works well.
I didn't compiled the kext. I just installed it via kextinstaller.

tnx in advance.

Nov 4 2009, 02:05 AM

No, but someone else compiled the kext. I still have a lot to learn about this stuff, so I have nothing for any solutions :/
It does appear that the kext may have to be recompiled for it to work for this newer version, would any of you guys happen to know how to work with the source? I can compile really basic code, but I'm clueless once there's all sorts of files included.

Hi guys! Sound working on SnowLeopard with CMI8738!

I've been able to compile from sources the kext for CMI8738 chipsets!
Output working perfectly under 10.6.0 64-bit. You will find the kext attached to this post.

simply place the kext in the extensions folder? and also worked with DSDT?. because I'm working DSDT with ac662 and really do not want more ... if so, could you please pass me the code you used in HDEF for CMI8738? and excuse my English-_-is a translator

sorry I don't use DSDT

I put the kext in the extra\extensions folder in my EFI partition
then I update extensions.mkext

reboot

and it works

honestly I never used DSDT and don't see the nedd to use it
my hardware is working fine with 10.6.2 totally untuched installation vanilla

Nov 13 2009, 08:20 PM

well thanks ... if someone worked with DSDT, where would you please attach it here? because honestly I need .. and I've done everything with this kext and for some reason does not recognize it .. I think it's because I'm using the ALC662 in hdef the DSDT, but if I delete the DSDT errors with the cmos, then I need a DSDT with Cmedia .. if someone feels sorry:( thanks

No luck for me... I get "cannot resolve dependencies for kernel"...has anyone else gotten this error?

EDIT: Nevermind, it seems to be loading now because I don't see any errors from it in -v mode, and kextload will load it up without fussing, but I still don't see my sound card under the sound settings. Any ideas?

EDIT 2: Nevermind again, I reseated the audio card and now it works! Haven't tried the analog, but the digital is putting out 2 channel PCM that sounds beautiful. Thank you shagui for doing that!
