What can I do to get my DigitalDevices Cine S2 v7 working in the latest LibreELEC alpha?
I haven't build a version for LE8 yet because it is still a moving target (I start as soon we hit beta/near to this). But you can try to update to latest LE 7.90.006 because an "homemade" DD patch was added (no guarantee that this patch made it to the final version) which support some DD cards ootb.
