If you wondering why Skype is not anymore working with your new shiny Intrepid Ibex 8.10 you’re not alone.
It seems pulseaudio is somehow responsible for this bad behaviour. To bring back everything to the normal situation:
sudo apt-get remove pulseaudio
sudo apt-get install pulseaudio ubuntu-desktop
This should solve the problem. It worked here at least.
Update: I found out that only the command
After that you have to launch skype and it should work.
The annoying bit is that you required to do that every time you want to use skype…
