There are some techniques to extract the sound exist:
1. The simplest one is
arecord -D hw:2,0 -r 32000 -c 2 -f S16_LE | aplay -
It gives stereo, but with too long delay in sound.
2. No delay, but mono only:
$ sox -r 32000 -w -t alsa hw:2,0 -t alsa hw:0,0
The neighbour method for stereo
$ sox -r 32000 -c 2 -w -t alsa hw:2,0 -t alsa hw:0,0
lacks :(
3. Experimentally I found the middle technique:
arecord -D hw:2,0 -r 32000 -c 2 -f S16_LE | sox -q -c 2 -r 32000 -w -t wav - -t alsa hw:0,0
Stereo, no lacks, delays rarely.
