I must partially correct myself. Indeed, after some minutes of usage and when there are many applications open, the DisplayLinkManager process almost constantly eats from 0,5 to 1 full core of my CPU (12%-25% of an i5 Haswell 4-core CPU).
Sometimes you won't notice it, but sometimes it slows down the system a lot...
The audio problem remains, too.
