I believe the cable issue came in with the software update to nougat which is why yours may have worked already which is why I was toying with the idea of rolling it back.
And by coincidence I actually turned off video caching anyway just because I couldn't figure out a use for it & the tablet didn't seem to be saving any of this for me anyway. What is the reason for wanting this enabled might I ask?
And I think the lineage is beta for my t713 too but it is supposed to be stable & bloat free but at this stage I will be keeping an open mind & look into all options including your fix
