    After messing around with the sound file types, I was eventually able to get it working. The button inputs are the opposite of the file title, though. Input 1 played sound 004, and input 4 played sound 001 and so on. Not plug and play, but for $20.00 not a bad thing. Couldn't sell it to the bosses, though. They were spooked by the "problems".
