Neither of my mini-ABB boards with Atom 28s will output any sound from the onboard speaker when I run the Rover ps2rov4b_bas program which outputs four quick ascending notes at the beginning of the program. And yes, I have speaker jumper installed.
I did notice that when I first powered up the Atom 28s on the mini-ABBs that I got a clicking sound from the speakers indicating that they do work.
I am presently using BasicATOM software version 5.3.1.0.
Is it me or is there a problem with Atom 28 and the sound command?
