Can anyone please help? I have a computer running Vista and when I try to play a DVD flim,CD Record or watch tv the sound is perfect for the background sound but the speach is very very quiet. Everything plays ok on my old conputer running Windows XP . I have borrowed a laptop also running Vista and the sound on that computer is the same. I borrowed it so I could copy the setting onto my Vista computer but they are both the same, quiet speach sound too quiet to hear.
