Thats what the dsnoop plugin is for. If you have a recent alsa version, dsnoop should be used by default. Try the following in two terminals at the same time: arecord -M -fdat | aplay -vv This should give you a display showing the peak level of the microphone. If this only works for the first instance, not the second, try the next one: arecord -M -Dplug:dsnoop -fdat | aplay -vv If it still does not work, try: arecord -M -Dplug:dsnoop -fdat | aplay -Dplug:dmix -vv Please report back which one works, and your alsa version (alsa driver version can be found via "cat /proc/asound/version", get to know the alsa library version depends on the package manager you use).
