Digidesign 003 & C24 problem [Pro Tools LE 8.0.3]

[Nathanael81]

Hello @ all

We've got a Hardware Issue in our Studio.

We are running Pro Tools LE [vers. 8.0.3] on a Dual Core PC with 3 Gigs of memory. The Interface we are using is the Digidesign 003 Rack.

We recently purchased the Digidesign C24 Controller and have the following problem, all the time we hit play the program stops an comes up with the following message:

The audio device buffer underflowed. If this occurs frequently, try decreasing the „H/W Buffer Size“ in the Playback Engine panel or remove other devices from the audio fire-wire bus. (-6085)

without the C24 the performance was running pretty well with only using the 003!!!


here is the List of everything I could find out about the system, including any INFO from Sandra Report

* Computer model and processor speed:
        - Asus P5LD2 C S775 Board (system bios: AMI 1903 07/20/2007)
            - Buses: ISA X-Bus PCI PCIe IMB USB Firewire/1394 i2c/SMBus
            - MP support [no]
            - MP APIC [yes]

        - Intel Pentium D925 Dual Core CPU 2x3 Gig Hz (internal data cache 2x16 kb, synchrone, write-thru, 8-way set, 64 byte)
            - L2 on Board cache 2x2 MB, ECC, synchone, ATC, 8-way set, 64 byte)
        - 3 Gig DIMM DDR2 RAM [Corsair CM2X512- Twin 2X 5400C4]
            2x 512MB PC2-5300U DDR2-666 [5-5-5-15 3-18-5-3]
            2x 1GB   PC2-5300U DDR2-666 [5-5-5-15 3-18-5-3]
        - Chip model: Intel 82945P Processor i/o controller
        - Front side Bus: 4x201 MHz (804 MHz)
        - Memory Bus Speed: 2x402 MHz (804 MHz)

    * OS version [Windows XP Professional 32 bit, SP3]
    * Digidesign or M-Audio hardware model [Digidesign 003 Rack]
    * Controller: [C24 Digidesign C24]
    * Pro Tools version [8.0.3]
    * Amount of RAM installed [3Gigs]


    * A complete and precise description of any attached peripherals:
            - hard drives:
                - 1x SATA Samsung HD250HJ 7200rpm; 8MB Cache (250 Gigs "System-Disk" NDFS)
                - 1x SATA Samsung SP2504C 7200rpm; 8MB Cache (250 Gigs "Data-Disk" NTFS)

            - video devices [NVIDIA G-force 7600GS (12PS3,0, 5VS3.0 401MHz, 512MB DDR3 2x 351MHz, PCIe 1,00x16)] 2x DVI
            - other firewire or USB devices [Firewire 3+1 PCI Card Logilink IEEE1394 >>> Digi 003 Rack ]
            - what type of cables you're using is it a FW800-FW400 adapter cable?
                - [the normal factory fire wire cable from Digidesign's 003 Rack]
                - Are you using an extender or repeater? [No]
                    

     * Number and type (firewire, SATA, SCSI, etc) of drives installed 
        - ULTRON UCR Card Reader 16 in 1 (internal USB Bus)]
        - Mouse and keyboard via PS2

* Troubleshooting we've already done:
- Changing the Buffer size from low to max
- change the CPU limit for the use of Pro Tools
- "Disabling Error Message"
- Reinstallling the whole Setup (Windows XP and ProTools)
- and Removing all old Plugins

- Installing Quicktime [version: 7.66]
- Installing Realtime [version: 1.1.4]

thanks for the support...

Ethernet Hub? 10, 100 1K base?
New session, with no plugs but mixer in plug-in folder.
Set up peripheral without MIDI controllers (None)
C/24 connection (Peripherals)
Add 24 mono audio.
Playback controls to 1 processor.
Is all recognized and functioning at this point?
----
FW external to 003 only or drives then 003 at the end of a chain.
MIDI in Pro Tools setup> controllers (issue)

Keep up posted.
