Ok. To bring a bit structure in the problem hunting, I will

a) concentrate first on the C720 which still beeps (to eliminate the
   risk that the other has a hardware issue)

b) let away X11, and use as test cases only:
   1. it should beep on key backspace while cursor is on prompt
   2. it should beep on a second ESC in editor vi 
   3. it should beep on the shell command: printf "\7"

The C720 in question runs r292778 and beeps fine in test cases 1, 2 and 3.

I produced an USB stick with a bootable system from CURRENT of tonight,
r303343, with the exact same configuration:

kernel GENERIC
same /boot/loader.conf
same /boot/device.hints
same /etc/rc.conf

The r303343 does fail on the above test cases on the same hardware. Why?
