[MPlayer-users] Can I use mplayer/mencoder to capture the audio the Linux PC is playing to a file?

[James Board]

I'm trying to figure out the easiest way to capture the audio that my Linux PC is
playing and save it to a file.  I don't want to capture from a URL.  I also don't want
to capture through the microphone, or analog capture device.  I simply want to
capture the bits that are being sent to the sound card.  Can this be done with either
mplayer or mencoder?  If not, what's the easiest way to do this?
