With just a little fiddling, you can create a "looprec" device that has loops back the audio output into a new recordable ALSA device. The steps, just like in the above-mentioned post, are: $ sudo modprobe snd_aloop (this inserts the relevant kernel module into the kernel) create/edit ~/.asoundrc and paste in the following (a bit of alsa black magic):
