Scope app flat lining on both channels

[Howardlong]

I can get the scope app to fire up, but neither channel shows any signal. There is an offset on the channels when you increase the sensitivity, it's completely flatlined, no noise, nothing, even at the highest sensitivity. All jumpers are on the LV setting. The spectrum analyser app works fine, so I assume the hardware is fine. I've used a variety of signal sources including that from a Siglent SDG1025, and the AWGs/function generators on an Agilent MSOX3054A and Tek MDO3054, and checked the signals are there at the RP's SMA with a scope.

My SD Card image is "Stable OS Release" in Quick Start.

Second RP now here, same problem, scope is flatlined, only the offsets are visible when you increase the sensitivity. Code is the current stable.

Built in scope app doesn't work, but I just downloaded the one on the Bazaar and at least now something happens.
