Tascam Fw1884/pod Pro/cubase Sx Syncing Options

[Pat Hargan]

Hi, I would welcome any help anyone can give me regarding a troublesome sync problem. I'm running a Line 6 Pod Pro via SPDIF into a Tascam FW1884 which is connected to a G4 Powerbook via Firewire, and I'm recording with Cubase SX.

The problem is this: the Pod doesn't have a clock input, so I'm slaving the clock for the Tascam/Mac and Cubase to the digital signal from the Pod. I've set the Tascam driver, the main Mac audio setup and the Cubase device setup to SPDIF clock settings, but the signal comes up on the Tascam as intermittent (the D IN LED blinks instead of showing solid). When this happens, horrible loud cracking noises come through my new monitors in a most distressing way.

Has anyone had similar problems or have any idea what the problem might be? I'm guessing the Tascam driver software is prime suspect rather than the Pod's output signal. Any help much appreciated.
