I've been following this thread with interest. >From a later message from the list archive (not here yet) you say: > 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" I don't use vi, but 1 and 3 work here fine both from a VT and within KDE, however I have KDE send 'beep' notifications rather than speaker. You seem to assume that something's broken in FreeBSD - which may be the case - but it's also possible that the speaker hardware on the non- beeping one is just broken, especially as device speaker didn't work. Usually the hardware for these in laptops is a simple piezo speaker, commonly with red and blue wires, likely driven by a single TTL or CMOS buffer. While piezo speakers are pretty hard (but not impossible) to destroy, I've had a laptop where one wire has become detached, so if it's not too hard to get in there to check, that may be worthwhile .. if so it's likely a simple fix, either by soldering or replacement. Another possibility is that it's (become?) disabled in BIOS settings? To confirm it isn't (or is) a FreeBSD problem, try booting from an older version memstick in 'live CD' mode, from where a simple backspace at the console prompt should quickly confirm that, one way or t'other. cheers, Ian
