Your ardour project is set at a certain sample rate as mandated by
jack. This is probably jack's default of 48KHz. Your samples will by
played back at this rate regardless of their original sampling frequency
(probably 44.1KHz by the sound of it).

- restart jack at 44.1KHz, and reload your project. Ardour will
complain about the change in frequency but should still work.
- restart jack at 44.1KHz and start a new project, to avoid complaints!
- resample your original sources at 48KHz and reimport them.

Audacity does not use jack, and is therefore not constrained by the
sample rate at which jack is running. It will play your samples at
the originally sampled speed, thus they will sound fine.
