Wow, 10/10 for persistence, Matthias .. and this is something I doubt 
anyone would have noticed, even had you shown mixer settings earlier. I 
guess they must have just used the mixer igain 'slot' for the speaker.

I'm sure we're all glad you managed to solve it, despite our 'help' :)

Two questions: Do values apart than 50 provide different beep volumes, 
or is it off/on?  And does 'kldload speaker ; spkrtest' work with it?

cheers, Ian
