Another quick one. I was having trouble with Skype in the recent Linux Mint 16 RC with Cinnamon 2.0 (an otherwise fantastic release). Skype was showing a long list of audio devices and utilising Alsa, which was causing some problems when other sound events occurred via Pulse.
To fix, just run:
sudo apt-get install libpulse0:i386And restart Skype, hopefully that's that.
