i am getting pretty terrible digital crackles from my Apogee Ensemble pro audio device.
It is connected via firewire. it worked flawlessly before.
i just did a major jump from Leo4All v3 - 10.5.2
to iDeneb Combo 10.5.7 upgrade. after experiencing audio problems,
i decided to update to 10.5.8 using iDeneb's 10.5.8 updater.
i am now using Qoopz 9.8 kernel which i have to say has made my
system very zippy! but alas, my problem still exists.
i should note that during the boot process i get this message:
"FireWire unable to determine security-mode; defaulting to to full-secure"
i have a P4 530 3 ghz chip in an ASUS P5WD2 Premium board. Intel 955X chipset. TI 1394a firewire chip.
do i need to do some .kext fiddling? i haven't changed any kexts
since updating from 10.5.2 > 10.5.7 > 10.5.8
thanx!

update:
i tried using AnV's AppleSMBIOS.kext, but to no avail.
my motherboard's firewire chip is a TI 8023.
today, i bought a Lucent 5091 PCIe board to see if that would work.
same result.
i also tried AnV's new 9.8 kernel.
and i've installed Chameleon 2.0 RC2.
i can't seem to change my macmodel info.
i've set it to MacPro3,1 in com.boot.Apple.plist
it still boots saying my system is MacBookPro5,1
using AnV's -nomacmodeloverride switch,
it comes up as MacBook2,1. dunno, if that makes a difference anyways.
thanx for reading!
becoming despondent...
