My 4-week-old Vaio has all of a sudden stopped playing muic files. This is either on Windows Media Player or on iTunes etc. It also on when restarted comes up with a message saying the Dolby Audio Driver has stopped working. But i cannot find any trace of it to reinstall it so, so far i have only installed any other audio drivers i can fine within the pc but to no avail. Any help as to where to find this driver or as to what to do or try next would be greatly appreciated. Thanks Will
