How about dropping a small coil spring in the hole, and then inserting the
broken off post? Perhaps a spring from a ball-point pen, or similar. Then
hold everything in place with some ingenious solution you come up with, such
as: 1.) string 2.) Hot glue 3.) C/A glue 4.) Tie wrap 5.) Very small clamp,
etc.

Could you run in a small self-tapping screw until it makes contact with the
broken, hidden stub, and then attach your speaker wire to that?

Or, drill and tap the hole to accept an appropriate length of all-thread.
Then tie your speaker wire to it with two nuts.
