I just built a new system around a P4 1.7 Ghz processor and the Intel 850i chipset with 512 megs of RDRAM. Using a MOTU 2408 as my interface between my DA-78 HR's, Mackie D8B and my computer. Nearly every time that I arm a track, in Vegas Audio 2.0, to record, the system hangs!! This only happens when I select one of the MOTU ports as my input source for the track (ie. if I select my SoundMax sound card as the input source, no problems). I have tried assigning the MOTU card to different IRQ's, using different PCI slots, reinstalling the drivers, and reinstalling Vegas all to no avail. Any ideas would be greatly appreciated!!! Thanks!!!!!
