[Audio Support] re firewire and sound /KEXT installation
Just installed osx on an asus p5k, everything working except the ethernet, and sound is working on 2 channels but with aliasing (digital distortion)---pci ethernet card working---I use a motu 896 HD firewire sound interface--which is very high quality--but not unbder OSX--loads of drop outs and glitches, and different behaviour under different kernels--I am new to OSX, but prety good on PC.
Anyone got any solutions re firewire driversKexts--and can someone please describe step by step how you install kexts _HELP!!!!!
Also is there a limit to PCI slots being used? when I install an ethernet card, the other slots dont seem to work--are there bios issues relating to interrupts here--and could this also affect firewir performance
It can be that your first PCI slot doesnt work (shared IRQ with the VGA card). The same for the last PCI slot.
For Kext installation, just use Kext Helper

You need ASIO/Core Audio driver and some .kext to enable full audio support.
If you have original disks, look on it.
Or try find it on:
Require free registration.
I have a Leo4All 10.5.2 install on my x86 box that I built years ago, and I don't use the on board sound (which does actually work, but I have a better PCI card, Audigy2, that does 24/96 with the right ASIO drivers in Cubase and Nuendo.) so I decided to give it a miss.) I record music so I wanted a better solution than the shit line in that is built in on my G4 and even though the line in on the Audigy is high quality and the card is 24/96, it is not supported under OS X.
My Pro Tools Digi 001 only goes to 10.4.6 with Pro Tools LE 6.4 or XP SP2 with 6.4 LE. I decided to try a firewire interface and got a Miglia Harmony Audio Firewire. 2 in and 8 out. It was 40 bucks from Amazon. Under XP the latency was so bad it is unuseable for recording but my Mac with Tiger and Leopard it is good in Garage Band and as a sound card/interface. Logic I haven't gotten to work but Logic is a pain. It should work right out of the box with the core audio drivers with Leo or Tiger. If not, check the firewire card. It may have issues. There is a core audio update that supports most devices and you may also want to look into your memory. If you are low on memory, you will get that too. The other thing is the audio buffer. How big is it?
The PCI slot issue is a different story. What chipset? What version of Os X? 10.4? 10.5? What distro? Did you install the correct chipset drivers? Is the motherboard supported completely? What ethernet card? There are some that just won't work without some serious tweaking and others not at all. The PCI thing is not necessarily cut and dry. There are IO kexts that work differently with various manufacturers chipset versions. Also a lot of PC architecture PCI cards will not work with OS X even in x86 boxes because their firmware is different for PC or Mac (ie, video cards.) They may be a hardware match, but the OS doesn't see them. That doesn't mean the hardware is faulty tho.
Did you try rearranging the order of the cards in the slots and skip the first and last slots? Sometimes the OS will not see the slot if it is use shared IRQ.
Installing the kext files is easy, but there are steps. Backing up the original kext files is first and most important. If you kill the install, it is better to have copies of the original files that you can copy back than reinstalling the whole thing. Copying them to /System/Library/Extensions is of course the next step. You need to either be logged in as root or know the root password for authentication. After you copy the files to the extension directory you need to delete the /System/Library/Extensions.mkext file. You need to do that in both 10.4 and 10.5. In 10.4 there is a second extensions kext file in that folder that you need to delete but I forget the name. The file doesn't exist in 10.5.
The next step is setting ownership and permissions flags for the files. A lot of people (including myself sometimes when I am not feeling lazy) manually set ownership and permissions in a terminal window with chown and chmod, but the easy way is run disk utility and repair permissions, either before you reboot or you can reboot from the install DVD and run Disk Utility from there. There are also a bunch of utilites that can do it, like ONYX. Your choice.
If you need more help, let me know.
And when you are dead you will dream of me ...
When choosing a FW card for audio always look for the Texas Instruments chipset. Siig, in particular, work great and are Digidesign qualified.
