Hi Subbu,

thanks, that did it. Squeak playing Audio with the problems described,
Scratch one through the menu still w/o audio (as expected) but both
showing up in the pavucontrol. Except that now I have a crackling noise
when using the volume control (Crossfade still being a secret to some
audio implementors, really :-)

So on to electrical recording and then try to implement Tim's suggestion
on recording the buffers from Squeak.
