Ha! Very clever, I would never have thought of this! :-) And I may just 
end up doing it (actually i already found the right lead and did). The 
sound out of this laptop is pretty bad and it's only a mini-jack out, 
but I only need to send a voice synthesiser through to the main 
speakers, so it will do at a pinch. Just the risk that the plug pulls 
out or gets noisy or something like that.

Interesting, I'll look into to this. So you think the problem exists 
between PulseAudio on the Asterisk side communicating with jack on my 
user's side? Makes sense.

Thanks for your help.
