I just listened to the opening few notes of Star Trek [!] But very faint and I don't know if the dinky BEL is a chip or a real speaker. Anybody know how I can redirect the beep to my speakers?

Probably help to be a dog! --That reminds me of what my parents generation were saying about mine [with its loud music]. That we'd all be nerve-deaf by age 55.-- Teh computer does beep as an error sound.

But if you're really keen: Def !fun, but not rocket science either. I'll poke around at this stuff. > > % find /sys/ -name "speaker*" -o -name "spkr*" I've found spkr.c; still there after all these months, :) thanks again, gary PS: this might be interesting: I just tried to get % xset c 50 and % xset on on my Ubuntu Thinkpad.
