It was previously thought that there was a collision with the pins of the water flow sensor and the audio cape so we decided to scrap using the beaglebone for audio but inspection of the beaglebone wiki shows that we're not colliding with any of the pins we're already using. This means that using the audio cape rev B is now a possibility. The only problem is that this piece of hardware is now out of stockv at boardZoo.
