If that does not work, go to the device Manufacturer's website and download the latest drivers for Audio and installing those and check. Eserpess der 2012-09-03 01:40:11 Re-Click the X and it should disappear, then you should get your sound back. Then make shore that the sound bar isn't all the way down my old system ran Windows 7 and I had that issue all the time. If all else fails turn it off and on again.
