I have a Bushnell that has audio, as well as my Moultrie M80. I know many of the Stealthcam models have audio. If you can wait another month or two most of the camera makers will be coming out with their 2013 models and you never know what new features they'll be adding. Of the cameras listed I would go with the Bushnell. Hard to beat a two year warranty.
