$ avconv -f pulse -i default test.wav

Pulseaudio is the default sound system in most used distro Ubuntu
So - Pulseaudio should be supported.
Pulseaudio lets me record from "monitor" source
=> PA support is necessary to grab desktop with sound without manual switch of
source in pulseaudio control panel.
