Hi everyone, I realize FW-1884 has frequent FireWire connection issues and is kind of a picky piece of gear. I've had this unit since 2006 and its serial number is 0120089, so I guess it's one of the earliest, before they made some improvements around the 028xxxx series. Let me start by giving my system specs: Soft: Windows 7 64Bit; Nuendo 5; FW-1884 Driver 1.8. Hard: Motherboard: Tyan Tempest i5000XT; CPU: Intel Xeon 5100; Ram: 6GB DDR2 FBDimm; Graphics: ATI 2600XT... And I do have a Texas Instruments FireWire onboard device, with its driver rolled back to legacy. My FW-1884 unit has worked and stopped working many times with the exact same Workstation. Namely, every time I move the Studio to a new location, or every time I format the workstation, I have a hard time getting the device to work reliably again. Right now after moving the Studio to a new location, I have been struggling with the following problem for a few weeks: I always need to turn the Workstation on, before the FW-1884, in order for it to be recognized and for the FireWire Led to light up. I turn the WS on, after Windows has fully loaded, I turn the FW-1884 on. I wait around 30 seconds and the Firewire led turns on, at the same time that the red cross disappears from my Audio Device icon, in the system tray. Also, the FW-1884 shows up twice at the Control Panel, but I had to disable onboard sound device, otherwise it wouldn't work. However despite all this and despite the Firewire remaining on, I have no sound through the FW-1884... And the FW-1884 control panel shows no sign of Sync. It also doesn't pop up when I click it on the unit, of course. When I open a Nuendo project and use the software interface, what I do (play, stop, mute, level knobs...) reflects on the FW-1884. But not the other way around: What I do in Nuendo has no effect on the FW-1884, which seems to be receiving DAW commands through Firewire, but not sending them. However I don't get any sound out of it... Not in Computer mode nor in Mon Mix>Computer/Both. I do get sound out of it if the inputs are jacks or XLR... But not from the workstation connected through FireWire. Can this be the FireWire cable?.. Can it be the Firewire ports? Can it be the on board Firewire card? What really annoys me is that I don't know of any other device that can replace the FW-1884 with all it's inputs and outputs and which can work both as mixer and as DAW controller... Which is exactly what i need for my workflow. NOTE: This is all with FireWire port #2. With FireWire port #1, after lighting up for a second, the led goes off... But all the rest remains the same: The tray icon remains with audio active and the FW-1884 keeps active at the Device Manager. However only with port #2 will the FW led remain On. In the past, I've had similar problems, but they seemed to magically vanish after some time. I just don't get why this keeps happening every time I move things around or when I format the WS. I sometimes would leave both the FW and the WS on for several hours and after a while all went back to normal.
