Those are the right values.  min == max -> not adjustable

I see.  Thanks.  So  that means "self.subdev.set_gain(options.gain)" has no effect, right?

Mike - is this why in your usrp_replay_cfile.py file you use self.amp?

This change didn't actually make a difference, but self.subdev.set_enable(True) that Mike suggested did the trick.  And in fact, it's right there in my cc file.  Laughing at me for missing it.

Thanks a lot Eric and Mike!
