Help! No I/O on my d8b

[lonotes]

My d8b is connected to my HD2496 via 3 OPT-8 cards, and to my pc through s/pdif and analog connections on my Presonus Firebox. It has been working perfectly for about three years in this configuration. Suddenly, yesterday it has decided that it doesn't see any signal from any source. Nothing from the OPT-8 cards. Nothing from the Presonus, either digital or analog, and nothing from a mic connected to an input channel (no, I haven't checked every channel. With the simultaneous shutdown of everything else, it didn't seem necessary to check every channel). I don't know if it had anything to do with the problem, but I do recall a dialog box warning me that I was about to reset the board to the factory defaults just before the problem surfaced. But I am unable to find anything in the setup screen that looks obviously wrong. Everything else seems to be working fine, i.e. physical faders and v-pots respond to on-screen manipulation and vice-versa. SMPTE counter begins to move when the recorder begins playback. The recorder can be stopped and started from the d8b control. Everything works, except there is no sound. After poking around on the board and in the manual for nearly 24 hours now, I'm stumped. Any help or suggestions will be appreciated.

Do you have any clock happening? With everything turned on is there a blinking "?" in the VFD window on the console? Sounds like a clock issue to me, as in there is no clock. That is where I would start.

I think I know what you mean. Further to the suggestion crash made, it could be this. It should be called tenyearitis.

While you're in there, reseat the other cables and their destinations.

Nope. No blinking "?" in the display. I'm really hoping that I don't have to dive in and begin tinkering with the insides. Are there no "hidden" settings that may have been changed? The manual tells me that I should be able to reset to snapshot 00 to return to factory defaults, but there is no snapshot 00 in my list. By the way, I'm not disregarding the ribbon cable suggestion. It just was so sudden, and so close to the "reset to default" dialog box that a setting change makes more sense to me than a hardware issue. Hey, a guy can dream, can't he?

Other things to check.... Make sure that the clock master/slave settings have not reset to something odd. Maybe get down to just a connection between the d8b and the HDR with the Firebox out of the equation, just for troubleshooting purposes.

Look at your tape I/O window in the setup window and make sure you have all of your cards being recognized. Anyhorizon may have thrown you the right bone.

Clock M/S settings sound like something that could have reasonably changed. But I can't remember where they are located. Where are those settings found so that I may check them?

Oh, I forgot, all of my Opt 8 cards show up, as does the AIO 8 on the Alt 1-8. However, the input and output fields are blank on all four entries.

The OPT-8 and AIO-8 cards don't show I/O allocations. It's understood. You're gonna have to dive.

I was just trying to make sure he could see the cards show up. I have had an issue where one of my cards quits passing audio and when that happens the card does not show up. I was ruling out a card cage failure of some sort but since they show up, I agree, time to pop the bottom most likely.

The DIO.8 shows input output info since you have a choice of adat or tdif, your cards are only one choice only, as Peter says.
