In case anyone is following this - I have done some experiments with  
my old Griffin iMic too, and it manifests the same behaviour on that  
particular box... So, there seems to be something bad about how that  
particular box is setup wrt Csound.
The consequence of this is that TamTam gets "confused" - with sound  
cards disabled on this box, TamTam starts/quits/restarts fine (but no  
sound comes out of course!)
With *any* sound card enabled, TamTam starts (and clicks  
continuously) but hangs up when I try to quit it, and will not then  
restart.

But this is not a TamTam issue, there is something awry in my  
soundcard config.
I'm now trying to find bits for a third box, for yet another take on  
this...

OK, I've started reading up on this, although I'm not sure if I'll be  
able to take advantage of that, I don't know if/how/where Sugar/ 
TamTam adjust the Csound buffer sizes...

Also, from my reading - should "B" not be set to the next power  
bigger than "b", e.g. -b2048 -B4096 ? Or do I have more reading to do?
