Hello tec9, Hmm, unfortunally, Linux is not all sunshine. It's impossible to use the headphones on the PC. So there is still something wrong. I also tried windows afterwards, but sadly, I can only confirm what you are saying. I tried a clean install of windows, update of the drivers (downgrading the drivers), every possible update there is for windows; but no sound available. Strange, because before the bios update, it was working perfectly! I guess this is the reason why they deliver the PC with an older BIOS firmware, however, it would be nice to get some help from the Medion-experts. So, for the medion-expert, is there something we can test further? Do you need more information from our side? Can you confirm maybe what we are experiencing, or is there another reason why the PC's are delivered with version 207? Greetings,
