In general, to start with, you should pick a recording of voice rather than music since that's the sort of echo that is designed to be cancelled. I've noticed varying degrees of success for music with speex and much better success with the webrtc canceller, but starting with the basics is better. Also, if you're hitting trouble with double-resampling, you could resample the file to what the canceller sink supports before doing your test.
