    Hey All;

    I'm in desperate need of some help troubleshooting my system-I've spent all weekend setting it up and I'm still having glitches.

    I posted this down in DAWworld as well but thought I might catch a few eyes up here that don't check down there...

    I recently switched from a Delta1010 to a Digiface/Lucid 8824 setup-the computer has stayed the same, but now I get glitches every now and then when recording at 24 bit.
    I just tested the card out and for 1/2 hour of recording nothing(no inputs hooked up to 8824) on 8 tracks, 4 or 5 digital glitches appeared. After repeated tests at 8 tracks/24 bit, various #'s of glitches(always under 10) show up in seemingly random places-some tracks have now, others have 1, others have a couple or a few.

    I've reformatted the OS drive, tried ACPI on and off, USB on or disabled, and with or without the VIA drivers, but still I have these %^&#$ glitches! I've also turned bus mastering off on the Matrox, installed only XP and Vegas, Made sure DMA settings were right and done performance tweaks...and still glitches. I'm recording to a 5GB partition that's empty each time.

    Here's the clincher: 16 bit works fine with both 8 AND 16 tracks at over 1/2 hour....

    Maybe someone can shed some enlightenment as to recommended BIOS settings....or would putting the PCI card in a different slot work better?(I chose one that didn't share an IRQ with any other slot)

    As for the external gear-I'm using a GenX6 to clock the Digiface, ADA8824 and the Digimax-I am using 75ohm BNC video cables I had(are wordclock cables any different?? i was told these should work fine) that are all under 6 feet long. The HDSP is installed fine and it shows a lock to the incoming wordclock, as does the 8824. The buffer size in the HDSP settings is 512(i've tried others) and ADAT1 and 2 are locked to wordclock.

    I'm really hoping to use this system for a gig this weekend, and I want to iron these details out to make the system rock solid with 16 tracks-I have a Digimax I haven't even bothered to hook up yet....

    Thanks in advance,
    Eric Warren

    Well, since it's been narrowed down to PCI throughput(16 tracks at 16 bit works fine...) I'm gonna keep this going down in the DAWworld section...please if you have a digiface, or matrox 6550, or Iwill KK240+, offer up any insight you can think of!!
