Hey folks!
So we had an interesting thing happen this weekend:
Our system is a dm48 w/ dante option card + c2500 (FOH,) and a cdm32 w/ dante card + c2500 (Live Web/multitrack recording.) Still running 1.4.
Audio comes in @ DM48 and I use the tie lines to send all those inputs to cdm32, then on cdm32 I pass those on to a Mac Pro for the multitrack via those tie lines.
I also have a Mac Mini running DSP (Live Professor 2,) on DANTE inserts for things like vocals. (AutoTune, some Fab Filter plugs, etc.)
Dante Primary is connected to a series of switches we’ve installed in-house (all to spec.) Dante Secondary @ DM48 FOH is connected directly to dante secondary @ cdm32 Web rack. …so if primary dies, we lose Auto Tune, but errythang else passes through. (Full secondary redundancy is in the pipeline.)
Saturday I ran band rehearsals, web mix, and multitrack - no issues whatsoever. Sunday morning we booted the system back up again and there was zero dante audio going from FOH to anywhere else. I confirmed it was not a network issue, I confirmed that DANTE was still passing to/from everywhere to cdm32 Web rack. I confirmed, via dante controller that the DM48 DANTE card was showing up, active, and reporting that it was working just fine. Primary/secondary were connected, patching/unpatching i/o in controller worked just fine, from multiple locations.
i/o was properly routed in Dlive to tie-lines. Checked logs, zero errors reported anywhere. Both Primary and Secondary ports were showing activity. Yet… still no audio.
I rebooted the system once and it didn’t fix it. Had to run our first service with no multitrack or web (we have a backup analogue sub-mix from FOH for that scenario.)
Between service 1-2 I turned the whole thing off, removed and re-seated the Dante card in the dm48 FOH rack, rebooted the system, and everything worked just fine. Secondary came back online immediately, primary shortly after, (switches take a minute or two to boot.)
I wanted to at least post this experience here, as it is somewhat concerning. I still don’t know exactly what happened but it clearly had to be an issue internally in the dLive console. IE - some kind of non-communication between the console and the AH card. Hoping it doesn’t happen again, but I’ve got a backup plan just in case!
