Hi Kiril, I am also interested in this bug because I had the same problem also on Windows (and I'm thinking of installing Ubuntu as well). The same problem (no sound from headphones after waking up from sleep mode) is present in Windows 8/8.1 and the solution is simply to install the Hotkey control center from Clevo (it's in the drivers page, latest version is 6.0100 or 8.0100 respectively for Win7 and Win8).
After doing some research I identified the root of a possible solution in the file initHeadphones.exe (which, unfortunately, is not present in the latest version).
