One of the things I have found with OS X 10.2 is that the sound 
system often gets a little confused. The symptoms include:

* Mic input plays through to output

* Poor quality sound input

When I look at the display from Audio MIDI Setup (Utilities folder), 
it often shows the controller to be one thing and the device to be 
something entirely different. (These probably parallel the Sound and 
Speech system preference panels.)

For example, I have a Talkpro mic connected to an Andrea Pod USB 
adapter. Audio MIDI Setup almost always shows the controller to be 
the Pod (AK5370), but the input device to be the "built in audio 
controller". This works, but not as well as setting the input device 
to be AK5370 also.

I have found this to happen using both Via Voice and iListen, and 
also with the NC7100 mic that came with Via Voice.

I would be interested to know whether this is something peculiar to 
my Macs (G4/400 and G4/450DP) or whether it is a general problem.
