hi.. Thanks Rob for the suggestion. but unfortunately it doesn't effect much. The sound still in leverage level. But I see inside the win 7 sapo is less compare to the vista. I refer this link http://msdn.microsoft.com/en-us/library/ff539258.aspx and my system. for example there is no Enhanced Sound for Laptop Computers feature. Would be hidden, need some setting in win7? any suggestion? Regards, Muhammad Firdaus B.
