Interesting.
The AVTS has an
internal speaker, but there is a hardware problem with the current sound system
so it is basically inaudible. But even if that were fixed in a later
release board rev, its doubtful that the little speaker would project 20".
We can plug an external speaker into the VIBS audio port, but the fun
question here is how to power it and how to stop voters from borrowing
them. In short, I defer to Global's hardware development
department.
On the software
front, playing any sound they like when the ballot is cast will require exactly
one line of code.
