Is This an Android, or Samsung Problem, or What?
OK, purchased from a bricks and mortar store greatly reduces the risk of a fake card (doesn't completely eliminate, they sometimes get into supply chains, but a big, big reduction in probability).Thanks Hadron. IT IS a SEPARATE SD card that I purchased at Walmart. I tried your 1st solution, downloading the replacement from my OneDrive, which played fine before I downloaded it, but as soon as I tried to play it after downloading it wouldn't work. And as I mentioned, I downloaded the VLC media app, and it did the same thing.
So what app do you use when playing from OneDrive? Though if you recorded them and then remixed them I don't think it likely that the output of that somehow has DRM in it (in fact if you recorded them why would it have DRM in the first place?). But that leaves the question of what is going on unanswered.
