I have found a solution on this list.
You need to know your monitor device.
To look it up, do the following in a terminal:
$ pactl list | grep monitor
You need to install gstreamer-tools
$ sudo apt-get install gstreamer-tools
queue ! audioconvert ! wavenc ! filesink location=out.wav
I have noticed that the ogg version saves the sound only in mono.
There are other ways to do it with "pacat" but I wasn't been able to
convert the raw audio file with sox, as it seems it is broken in ubuntu
at the moment.
If someone has a hint for another program to convert the raw audio I
would appreciate it.
Just for completeness I will give you an example how to use "pacat"
$ pacat -r -d
To play the recording do this:
$ pacat test.pcm
I hope this solves your problem.
