Try this, it worked for me...no downloads or rebooting..quick fix.
Ever get the message, "iTunes has detected a problem with your audio configuration. Audio/Video playback may not operate properly."?
Here's one possible fix.
For Video problems: Open QuickTime Player and go to 'Edit' -> 'Preferences' -> 'QuickTime Preferences' -> 'File Types' -- check here to see if the file format of your problem video files is selected.
For Audio problems: Open QuickTime Player and go to 'Edit' -> 'Preferences' -> 'QuickTime Preferences' -> 'Audio' -- Here you will see a Device is needed that will play your sound. Select 'Audio Playback and Recording Devices'. I have Realtek AC'97 as my device. I had to reinstall it to fix my problem. If you are having an Audio problem it may be due to having no device or an improper device.
ANOTHER SOLUTION:
Not sure how to add another post/answer here so I am tagging onto the bottom. I had the same error message and uninstalled and reinstalled every driver, itunes, quicktime, you name it. Worked on it off and on for 3 days. The answer for me... the speakers had come unplugged from the back of the Computer. MAKE SURE YOUR SPEAKERS ARE ACTUALLY PLUGGED INTO THE BACK OF THE COMPUTER
