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
