Yes; been there, failed as well. Note the wording:  "Apple PlainTalk
Microphone...AND a standard stereo (miniplug-to-RCA)..." etc. They are
different cases.

The Apple plaintalk mike for the PowerMac has a minijack with an extra
connection in the middle to supply power to the microphone. If you look
inside the Mac, you'll see the connection in the end of the socket. If you
use a standard unpowered microphone, like the mikes used with, say, 475s,
the level is so low that it doesn't register. Unless the Sony you are using
has that power supply, or at least an output level to match that of the
Apple kit, it won't work.

If you record from your hifi or a Walkman (or a built in CD-ROM), with the
volume cranked up until you can see the response on the Mac level meter,
everything works fine.

So you could record via your hi-fi, or record a cassette and then play that
in via a Walkman. Or you could buy the Apple microphone. No, I haven't done
that either...
