I think I have done this before using Audacity, with the Alsa sound device driver.

just make sure your preferences are set to alsa, and you should be able to record.

Thanks very much for your reply!

But would you please tell me how to set the preferences to alsa, actually, I'm a beginner of it, not so familiar!

Thanks!

Howto: Record soundcard output with Audacity in KDE [Update: and Gnome] /home/liquidat

this site is helpful to set it up. If you are running KDE or have, you should have kmix, which is an audio mixer. This site says to click on the switches tab and enable 'mixer' but I only have mic as an input source. maybe you have other options.

If you open audacity and go to preferences, and click on the audio IO, it should say that you are using alsa for both playback and recording.

If you don't have kmix, you should still have alsamixer, which is a ncurses mixer, hit F5 to show all devices, and at the far right should be some way to activate 'mixer', again i only have mic. Press space to activate it.

Hope this helps some.

I cannot open the site, but I will try alsamixer also.
Thank you all the same!
