Thanks a lot for the explanation.
Yes it works with "cat /dev/dsp > /tmp/test" after having put the mixer on mono.
By the way, I have succeded in using arecord with this command :
arecord -D hw:0 -f S16_LE -t wav /tmp/test2.wav
without the -D hw:0 I get
ALSA lib pcm_dmix.c:947:(snd_pcm_dmix_open) The dmix plugin supports only
playback stream
it seems to be due to /etc/asound.conf :
pcm.!default {
type plug
slave.pcm "dmix"
}
Thanks again,
Alain
