Strange that I haven't memorized all your posts :-) ;-) :-) :-)

I use KDE/artsd.  Using this wrapper, as I always do, has no effect on 
the problem above.  Removing it had no effect either.

I don't use esd.

Done...long time ago.  artsshell status shows "suspended".


I can break the recording loop with alt-. and it shows that 
SoundRecorder is sitting in:

                n _ self primRecordSamplesInto: currentBuffer 
startingAt: nextIndex.

inside the ifFalse: block.  It seems that blocking in this prim now 
blocks the VM.  Really, I don't know...I'm just guessing.  Anyway sound 
in linux is a mess.  I've had problems on occasion with simple programs 
like rec or the KDE sound recorder so it never really bothered me that 
squeak's recording didn't work.
