You're almost there.
Once() is not what you need. It produces only one track over the
entire time-span of the source. It's mostly useful in transitions, not
here.
It's a one-minute-long interval. If your jingle is too long it won't
be cut. If it's less than one minute a second jingle would start. To
prevent that, you can use the delay() operator that prevents playing a
second track too soon.
local = fallback( track_sensitive = false,
transitions = [ cfade, cfade ],
[at({14h00}, delay(120.,jingles)), pl] )
I did not test but it should be fine. Also, I would use switch()
rather than fallback() and at(), passing 14h00 as the first predicate
and true as the second, it's more readable (and perhaps more used, so
more stable).
