Can't record digital signals

[earthling5615]

Hi,
Running PT 11.1.3 on Mavericks 10.9.3. I'm trying to get an album I made in 1997 into PT so I can remaster it. I have the AES/EBU output of the DAT (the mix down deck in 1997) going into my HD I/O. The level metering LED's of the HD I/O show the signal, at the levels expected. I've gone to the Hardware menu of the Setup menu and selected channels 1-2, then made channels 1-2 come from the AES/EBU encl input, which should be the built-in digital input.

I then go into the I/O menu of the setup menu, and moved channels 1-2 to digital in the input menu.

As I said, I have nicely bouncing LED's on the I/O, but I can get no signal into PT from the I/O.

It works fine when I switch inputs to one of my many analog sources, but if I go back to digital, the signal goes away.

MacPro 8 core, 16 GB ram, HDX system with 8x8x8 HD I/O. Any help you can give me will be appreciated. Thanks in advance.

Never mind, found the problem. I didn't notice that there was a different AES/EBU field to the left of analog for the encl input. I kept trying to assign it to digital 1-2 to the right of analog.

**OOPS SEE YOU FIXED IT **

I can't think if the interface display will show if there is a clock rate mismatch but what are all your sample rates? session rates? (remember the enclosure AES/EBU inputs don't do sample rate conversion, the digital cards in the HD I/O can if set to).

If that is not it posting screenshots of the device setup pages. Try digital inputs on the digital card (not enclosure inputs).

Worse case you can always try firing up Pro Tools using the Mac's internal digital S/PDIF as input (assuming your DAT player has S/PDIF, can't think of any that don't) and record the DAT output into that (or use any other DAW or utility that can record the digital AUDIO).
