Maybe I've miss the point in my previous mail...

This commande will do nothing by itself, but allow you to test if you
can record and playback at the same time : you have tu use your
microphone and headset (whatever you have to output) to check if you can
hear yourself.

Details :
First it records (arecord) from your microphone, -D plughw:0,0 using
your sound card directly (assuming you got only one...), -c 1 using one
channel (mono, wich is right if using 1 microphone), -r 8000 using a
rate at 8kHz (this is standard in VoIP except for the wideband codec),
-f S16_LE formatting datas in 16 bit little endian (that's the reason of
your message about little endian, this is just a way to put bits in
order, no worry)
Then it playback (aplay) to your output audio system (headset...) using
same settings.
