Just to report: Skype 188.8.131.52 installed from Synaptics working faultlessly on 14.04 mini install with xfce4, kernel 3.13.0-1-generic.
Adjustable in Pulseaudio Volume Control also.
* Just had a Skype to Skype call with a friend and audio crystal clear, video almost faultless (Skype can be a bit dodgy sometimes anyhow). I have no proprietary drivers installed for graphics, though, so that could make a difference.
I'm happy for now.
