Well after coming across an arduino port of an chiptune I like I then uploaded it to my Mega and plugged in speakers wired up to PWM 3 and ground.
Nothing plays at all :C
The original post for this was @ http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265488118 and all tutorials / posts online are using the Uno.
Does anyone know how to get this to work on the Mega (1280)?
Thanks - Ryan
