Incompatibility Asus p5b deluxe, firewire/1394, 2 Motu's 896
Posted: Thu Jun 21, 2007 2:51 am
Here••™s the thing: I••™ve got a brand new audio pc, based on the Asus P5B Deluxe motherboard. I also own two Motu 896 8 channel FireWire audio interfaces.
The don••™t work together!
Every time I tried to switch sample rates (in for example Nuendo 3) the Motu••™s go bezerk and one is not (clock)syncing. The clock sync light is blinking, sometimes it stays on the correct sample rate, most of the time the second Motu is not getting its sync at all. The consequences are clear; bad playback (glitches etc.) and no way I can record 16 channels in 44,1Khz (let go; 48, 88,2 or 96Khz). With only 1 Motu connected the situation is a bit better, but also not 100% error free. The FireWire card always has it••™s own IRQ (21) I want to use the 896 internal word clock.
What did I try:
-shorter FW cables
-both Motu••™s on separate cables/fw ports
-integrated fw chip on P5B (Texas Instruments), own/single IRQ 21
-(external) PCI FW card (TI, Via, Agere), own/single IRQ 21
-all possible Motu drivers I could get my hand on (5 versions)
-complete new installation OS etc.
-the XP SP2 ••˜registry hack••™ for FW800 support••¦..(http://support.microsoft.com/kb/885222/en-us)
-tried Nuendo (1.5.2, 2 & 3), Wavelab, Cubase (all with comparable problems)
I think I can bring the problem back to the combination of the motherboard (chipset, CPU?) and firewire, because in 3 other computers. All these also with the TI 1394/fw card/chip, (••˜older••™pc••™s though; PIV, 2,4 Ghz, PIII, 900Mhz) and they all work like a charm. I can record 88,2 in 16 channels with no problem and playback also with no errors.
Maybe the Core 2 Duo Intel CPU might be the problem••¦••¦
I don••™t know, maybe someone out here does!
Maybe using an external word clock could solve this but A. I don••™t want that (also portable purpose) and B. I know (see above) that it can work just fine••¦••¦
Question one is does anybody know a solution and another question might be, should I buy another motherboard and if yes; which one is known to perform well/stable in the professional audio world (what is THÉ motherboard to have!)
The full specs are:
MB: Asus P5B Deluxe, NB: Intel P965/G965 rev. C1, SB: Intel 82801HB/HR (ICH8/R) rev. 02
BIOS: 1101 Date 03/09/2007 (latest)
CPU: Intel Core 2 Duo E6400 @ 2.13GHz
MEM: 2048 MBytes DDR2, 333.3 MHz (4:5)
OS: Windows XP Prof SP2, all updates
Thanks in advance••¦••¦
