Apogee Ensemble (Firewire) crackles after update to 10.5.8: Firewire Full-Secure Mode!

Recommended Posts

hey!

 

i just did a major jump from Leo4All v3 - 10.5.2

to iDeneb Combo 10.5.7 upgrade.

 

i have a P4 530 3 ghz chip in an ASUS P5WD2 Premium board.

i've experimented with both AnV's 9.7 kernel and Qoopz Voodoo based 9.7.

both seem to work fine. i have not experienced any kernel panics, etc.

 

the one thing i have noticed is that i am getting pretty terrible digital crackles

from my Apogee Ensemble pro audio device. It is connected via firewire.

it worked flawlessly before.

 

any ideas?

 

thanx!

sir demon

after snooping around the last couple of days, i have figured out that the problem lies with this error:

 

"ERROR: FireWire unable to determine security-mode; defaulting to full-secure"

 

i have tried the following:

 

installed Chameleon 2.0 RC2

installed AnV's AppleSMBIOS.kext

installed AnV's 9.8 kernel

bought a PCIe firewire card with a Lucent 5091 chipset.

found out my motherboard firewire chip is a TI 8023.

 

still no progress!

You have to be able to use all EFI/NVRAM kexts (watch out for Disabler.kext).

 

I got rid of this error message but still had firewire issues using TI chipset, and kernel_task process was using much more CPU time when using firewire equipment.

 

cheers,
