hello this is varun tyagi
i recently installed genuine windows 7 on my IBM think center A51 (8123 LQ4) desktop
first i could not find audio drivers for my desktop.then i tried compatibility program offered by windows 7 and sound started coming from headphones.
but the problem is that when i play movies sound of music comes normal but the dialog are heard scratchy.i just can not hear what they saying while background score is playing well. I have checked my headphones are fine
what should i do to rectify this problem ?
