I have not heard from this kind of problem so far, which does not mean, that 
it does not exist ;)
Can you describe the beep sound?

After a quick look I can not pin point the soc board file used with the 
omap3evm board. Is it in the tree?

Does the beep happens in these cases also (after stopping it with Ctrl+C):
aplay -f dat /dev/zero
aplay -f dat /dev/urandom
