Questions and things to think about... Does the sound skip forward to catch up, cut out without apparent effect on sync, or stop to let the video catch up?
What player application? What video type? (file/streaming/?) Do you know the specific codecs involved?
Were the exact same files playing before the driver upgrade? Did you change anything else besides the driver? Did you try going back to the old driver? Official Forceware or external release?
Yes, audio and video are tied together in that there's a timebase and a heartbeat that synchronizes them during playback. Format varies by file type.

If they can be brought to raise questions and apply their decent instincts and basic intelligence, many people quickly escape the confines of the doctrinal system and are willing to do something to help others who are really suffering and oppressed." -Manufacturing Consent: Noam Chomsky and the Media, p. 195
