Great Soundcard-101 guide ! Tnx for that Jozef ;-)

We considered that enabling the microphone while recording was more 
"efficient" as - when you're during the contest - you don't lose the 
time it takes. The sound is automatically played back as you're recording.

Note that MICWHENPLAY/NOMICWHENPLAY was asked by some users to allow a 
more "natural" transition between the recorded messages and their own 
voice when a trailing personnal addition is needed.

We will consider your idea of muting playback output while recording, 
but (from the top of my head), I guess it is not easy, because today - 
especially with 5-1 cards - there can be several soundcard outputs to 
consider ! Anyway, food for thought.
