Sounds from line-in can be recored, but how to hear them in time?
Which console command can be used for this purpose?
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`.
Have fun,
Joel
