Yes I've seen those videos with pro board. The pro allows you to play 3 sounds using the control nobs. On the base board for a music/sound file on the SD card to start playing randomly is just plain weird. .ini file on the soundcard doesn't list that particular sound file as being associated with any command. Yet the song played and later I checked the SD card and found the exact song that played on there. So this is one heck of a mystery.
