Greywolf thanks, it loads without any error, but I cannot find my sound device under System Preferences - Audio. Shall I change something in the plist file or try to upgrade a newer OSX?

Thanks GreyWolf. It works like a charm.

I had no sound with my mobo chipset so I just went to Fry's and bought a cheap $12 soundcard -- a good solution for my particular situation.

Earlier in this thread it mentioned that this driver was output-only (i.e., no mic input). Is that still true?

Either way, my ears thank you for your efforts.

i did install the latest kext .6 every thing is enable in the sound preferences , volume control is showing ,but now sound . i tune also working without sound , i have green,red and blue on the sound card , speakers connected to green .

any solution ...

I've created a page for the driver which contains the source, the binaries for 10.4.1, 10.4.3 (works on 10.4.4 and 10.4.5, too) and some information for the driver - if you have some suggestions for the page, feel free t o mail me or post it here.

Sorry to bother everybody but I've tried all the things you said to install the dogbert's driver for my sound card (Hercules Muse 5.1 with the C-Media 8738 chipset) : I've copy the *.kext in the /Library/Extensions folder and I've used this command to load it : "kextload -t /System/Library/Extensions/CMI8738PCIAudioDriver.kext"

And OSX said that to me : kernel extension /System/Library/Extensions/CMI8738PCIAudioDriver.kext has problems:
Authentication failures
{
"File owner/permissions are incorrect" = (
"/System/Library/Extensions/CMI8738PCIAudioDriver.kext"
"/System/Library/Extensions/CMI8738PCIAudioDriver.kext/Contents/Info.plist"
"/System/Library/Extensions/CMI8738PCIAudioDriver.kext/Contents"
"/System/Library/Extensions/CMI8738PCIAudioDriver.kext/Contents/MacOS/CMI8738PCIAudioDriver"
"/System/Library/Extensions/CMI8738PCIAudioDriver.kext/Contents/MacOS"
)
}

What can I do???????????????????

rtfm.

If you havent already:
sudo -s
chown -R root:wheel /System/Library/Extensions/CMI8738PCIAudioDriver.kext
chmod -R 755 /System/Library/Extensions/CMI8738PCIAudioDriver.kext

& btw I deleted a couple of posts for readability

It works!!!!!!!!! Thanx

Hi, I don't know if this goes off topic but i've found a cheap sound card that works great in OSX 10.4.5 This card is the old Creative CT4810 PCI, whit this card, finally, I can plug my analog microphone. I have Line Out, Line In, Mic, CD IN, Stereo Mix, Mono Mix, and works great. I hope this help you out guys.

The ct4810 uses maxuuss's 1371 soundblaster driver, so it is a bit off-topic. some people experience soem stuttering with this card. The advantage is that it is often available free or cheap. I have 4 of them myself that I have picked up for nothing.

Thanks for the reply, but actually i use it just to plug my analog microphone, and for the line out I use my HD Audio Output. No more answers please cause this post is off-topic. Thanks and bye.

I'm using 10.4.6 and the process not works for me, when i run install.sh i get this message.



Please someone can it help me?

Nothing... keeps me saying that it's not compatible with its superclass....
I'm using JaS 10.4.6

hi everybody
since i have no luck with my onboard realtek ac97 audio ( sis 1039 7012 )

i've tried some old pci 5.1 soundcard flying round.
on the packing its written that this card has a c-media 8738 chip

// edit
(later found this thread)

Same problem here. Any solution yet?

Can you tell me how to recompile by myself? I have 10.4.6 too. I downloaded your file, but still get the superclass error.

It worked with that!!! I'm listening a MP3 right now in 10.4.6

But I can't get it work in 10.4.6

Try the one I mention above. I had the same problem as you and that one worked for me.

Installing the binary results in the same classic "xxx is not compatible with its superclass, 13IOAudioEngine superclass changed?" error that many others are getting.

When I download the source, open the project in XCode, and click "build", XCode simply terminates. Is there a simple commandline way to build this thing?

My environment:

Soyo P4I875P motherboard (w/ onboard CMedia CM8738 6 Ch.)

Thanks dogbert, Hydrasworld, and GreyWolf for the recompile (and anyone else who helped with this). Finally I have sound on my P4B266.

Anyone Using This Driver in Kernel 10.4.8?
My CMI8738 (Audiotrack Maya 5.1 LP) stopped working with 10.4.8 kernel. It was worked perfectly with 10.4.4 kernel with OS 10.4.6, 10.47 and 10.4.8. It stopped working with new 10.4.8 kernel.

I am Using Latest Semthex Kernel

Ye. We need to X Lab this driver and have some people who can recompile regularly for new OS X releases.

i've recompiled the driver myself, but the computer hangs after loading the kext.

hello to all, me son as soon as bought one Pci of sound with chip the 8738. I have 10.4.8 sse3 amd distribution with kernel 8.8.1, I have installed the CMI8738PCIAudioDriver.kext for 10.4.8. But he does not work I have made made several the permissions but then when I make:

They give the following error to me:

Help me!!!

WE NEED RECOMPILES FTFW!

How?? i can't use the xcode.

help me!!!

help yourself

there's a binary for 10.4.8 on my site which is reported to work.

what is your site ?
hi

Did you notice you can attach a headset to the lineout (or headphones out) and hear sounds? It sounds like the system recognize the card, but has some incomplete routing. I WANT MY SPEAKERS!!

He's site is http://scifi.pages.at/ffm-2/

I've tried this driver - All i get is a kernel panic, or no sound in safe mode. I've just bought a PC Line 5.1 sound card with the correct CMedia chip on it. Any ideas?

EDIT: Woops, I installed the driver for a different kernel 0.o. All sorted now, I just installed the right one and got rid of appleac97 as that was what was causing the kernel panic.

I have install this driver in my 10,4,8 system
I have an install succefully :

C-Media USB Audio...Help me get it working!

I need a little help getting sound on my Intel Mac. Anyone wanna help me take a shoot? The situation is as follows. I have SoundBlaster X-Fi card in my system, but the mac does not detect that. I don't think it detects any of my PCI devices, but this is another story…or maybe a partial solution. From what I've found, SoundBlaster X-Fi is not supported yet in OS X 10.4.X (maybe 10.5?).

Onto the point. In order to get sound out of my system, I checked the HCL on http://wiki.osx86project.org/ and found "C-Media USB Audio (no additional drivers required)" [Under USB Devices]. Well, looked like a dream come true and at only $26 too! Long story short…the no drivers situation is not the case. The USB device I have in my possession specifications can be found here http://www.siig.com/product.asp?pid=1048 notice it uses C-Media CMI102 chipset, So I'm still in the ballpark. Moving along, I came across this post and attempted to install Dogbert's driver. Didn't have any success either. I know its written in mind for PCI, but you never know. The similar error to everyone else in the form comes back at me. Tried all versions. The following is what comes back to me

thedc70s-computer:~ TheDC70$ /Users/TheDC70/Desktop/install.sh

The .kext in that directory. I've moved it there myself, after authenticating it, and evern left the .kext in the same directory as the install.sh file for excecution.

Also, in the system profiler, It is detected in the USB section
USB Audio:

Version: 0.10
Bus Power (mA): 500
Speed: Up to 12 Mb/sec
Manufacturer: C-Media INC.
Product ID: 0x0001

No option however in the sound section of the control panel.

So, Can anyone help me or point me in the right direction?

Thanks in Advance

Hi!!

With this driver I can solve de Input?

All function?
Input, Output, SPDIF??

Tanhks for your time

Short answer is: probably no

Output 100% works
Input is shown in Sound Preferences but might not work
SPDIF is not supported.


Source is included - so somebody skilled might fix it in the future... I'm satisfied with output

Regards

SPDIF out is working (at least on my card)

Does is support 5.1 Sound now?
