Play sounds on other than mac.

Current code is:

"/usr/bin/env afplay #{File.expand_path(__dir__ + '/Eudora-1.aiff &')}"

afplay is a command line tool from Apple Inc.

I thought a gem "audio-playback" is available! But I found that it was not easy to install. It depends on two libraries:

• libsndfile (link)
• portaudio (link) , which are outside of ruby gem world.
