Problem with Focusrite TwinTrak Pro...

[thebadsleepwell]

I run a small project studio out of my house and I just purchased a Focusrite TwinTrak Pro from sweetwater and had them install the optional A/D card. I run the S/PDIF output on it to my M-Audio ProjectMix I/O and from there to my computer via firewire. Anyway, I followed all the instructions in the manual, but when I fired it up my ProjectMix's console control panel showed spikes peaking out the input meters coming in on the S/PDIF channel, then settling down to a low level, but with no audible sound coming from it. Everything on the TwinTrak was zeroed out and turned off. I decided to move forward and powered up Pro Tools (8.0.1 M-Powered) but was met with a DAE error and once clicking OK Pro Tools closed. To make sure it was the TwinTrak I tried to run everything again with the TwinTrak off and Pro Tools ran fine. I have a session tomorrow and would really like to be able to use my new equipment, so if anyone can help, it would be greatly appreciated.

Do you have the interface's wordclock synced together using a bnc cable ?
That might be the problem. Once has to be the master clock source and the other a slave.

Since the twintrack also has spdif in you should be able to sync via spdif from the maudio spdif out -> twintrack spdif in.
