I thought that the details were not so useful, but here they are, if
you think they may help to find the answer:
1/ setting the line input of the sound card as input:
amixer -c 1 set Master,0 playback unmute 75%,75%
amixer -c 1 set Line,0 75%,75% mute cap
amixer -c 1 set Capture,0 75%,75% unmute cap
this works in all cases, i.e. I actually hear the sound coming from
the line input
2/ running arecord
arecord -d 10 -f cd -t wav tst.wav
this gives an empty file when run in a ssh window
NB: I also tried "xterm -e ssh mydesktop" instead of "ssh mydesktop"
with the same result (empty file)
