I did some more tests and have now a clear picture:

in Win7 you can control (System-control-->Sound-->Input) the input
devices (build-in micro ./. headset micro), you can test them there and
you can define which one is the default; if you set 'headset micro' as
default and pull it out, the default switches to build-in micro and back
again if you plug it in again;

if you start the VM while a) headset micro is pluged-in and b) set as
default, the recording in Skype works from headset micro; YES, it works!

if you pull out the headset micro, the recording (also in the VM with
Skype) falls back to build-in micro; but you can't switch back by
pluging it in again, is stays with build-in micro; even a FreeBSD guest
system reboot does not change it back; only a restart of VMWare bring
the headset micro again as default;

It looks like a bug in VMWare or Win7, I think, and nothing we could
address here in FreeBSD world, or?

Just for the record, se also
