I used to record "stereo mix" of soundcard output on Windows.

Read a few tutorials about using the "arecord" command to do the same thing on Linux.

However, using the following command only gives me the microphone input:

arecord -d 10 -f cd -t wav -D hw out.wav

which means, if I unplug the mic, I will hear nothing.

Is there a way to record the digital output or even back-end audio samples of the "stereo mix"?

Ubuntu 9.10, Realtek 92xx sound card

Thanks!
