I have a Nuendo I/O (identical to the ADI-8 PRO, just rebadged), that has mysteriously lost all output on the analog outputs 5-8.
It worked last night, but when turning on to use it today, it's all of a sudden died.  All of the analog inputs are working, as are the analog outputs 1-4.

Nothing has been changed, and I've flicked all the switches on the front with no luck.  Does anybody have any ideas what could cause this?  I'm thinking maybe it has gotten stuck on some sort of Bit Split/Combine mode so it isn't operating correctly.

Thanks for any help you may have,

Alistair
