erpsterm35 Sorry not providing you the appropriate details you asked... But surprisingly, yesterday i updated the driver in another way. I extracted the version which you suggested i.e. FF06 from the archive and updated my driver from Device Manager (Update Driver Software option). As my system is 64bits based, I opted the WIN64 Folder and viola, went well... Finally i have a updated version now with sound working. anndrey93 please try this method, as we have the same model, i think this should work on your side as well. Once again thanks erpsterm35 for all the help and support
