Thinking of it, there was a change to handling of files by dummy-ups around 2.8.0 release: depending on an explicit setting or a file extension:
> Specify mode instead of guessing it from port value (dummy = dummy-loop, dummy-once, repeater) : -x mode=<value> As the man page goes, by default "*.dev"=>"dummy-once" (emulate a device snapshot, so once to the end of file and stop) and "*.seq"=>"dummy-loop" (run a device behavior sequence, so looping).
