Hi, Not all sound cards are capable of simultaneous input and output (duplex operation.) Also, most distributions have pulseaudio installed as a layer of over ALSA. One solution using ALSA (with PA disabled) would be using ecasound. ecasound -i alsa,default -o alsa,default You could also try alsahw,0 instead of alsa,default, or alsahw,1, etc. depending on the number of your sound card. You can also use the name. For details use `cat /proc/asound/cards`.
