I'm a recovering 'EFiX-er', just switched over to a Chameleon solution. I had been using an HD3 Accel PCI system (use only one 192 box) on 10.5.8 with EFiX (on older firmware) and that was working great. I just built up the system with a fresh install of 10.6.2 Snow Leopard and PT HD 8.0.3 (the newest downloadable full installer that appeared in my account today). Note, the problems I'm about to describe also happen with this Chameleon setup running the same 10.5.8 setup that works with EFiX.
Installation went smoothly, and it all looked good. However, it did not sound good!
I imported some stereo audio at 48k, then later 44.1, and when I push play it starts playing but AUDIBLY loops about 2 seconds of the audio from where I played, with static. VISIBLY, Pro Tools looked to be playing along fine. (insertion was moving, the metering was following the sound I was hearing). The length of the loop is related to the disk buffer size, with larger buffer giving a longer loop.
Also, I was getting static (like digital clock problems) on some playing tracks. I managed to figure out that this happens only on tracks set to voices on A. So, if I put my playback engine to 192 voices and explicitly set a stereo track to play on any voices higher than A, let's say B 1-2, there is no static (still loops though!).
Also, attempting to send system sound (iTunes) out of the Digi Core Audio (by selecting in System Prefs, Sound, Output, Digidesign HD) does not work at all.
So, I'm a bit sad! But, not without hope. Could it be something to do with CPU identification possibly?
A further bit of info is that another Pro Tools / EFiX user contacted me previously stating that when he did an EFiX firmware update that he also had this static and looping problem. So, if EFiX steals from you guys, then I guess I need to go back to an older solution -- but of course for the good of the project we need to figure this out!
System specs at this time:
Gigabyte EP45T-UD3R bios F6 • Q9550 2.83Ghz Core 2 Quad processor • OCZ Gold 1333mhz DDR3 RAM, 2x2GB • 8600GT 512MB PCIe Video
Stock frequencies (not over-clocked) • PT HD3 Accel PCI + 1 192 IO Box
Chameleon 2 RC4 • Most mods done at DSDT, but needed EFI strings for Graphics and Sound • Vanilla Install with the following in e/e: CPUInjector.kext, fakesmc.kext, LegacyHDA.kext, NullCPUPowerManagement.kext, OpenHaltRestart.kext, PlatformUUID.kext
Graphics Enabler is off (didn't work), and using 32-bit kernel. smbios plist is saying I'm a MacPro3,1
Thanks for any help!!
