    EDIT: By troubleshooting this, I think it may be more of an XML problem that I'm having. Playing streaming video on the web, the audio does not work. Also, I occasionally get a XML warning dialog on my startpage. In fact, when I spotlighted XML files on my machine and tried to open one, it says it could not be opened. Does anyone know how to fix this short of reinstalling Safari or something like that?

    Hey Everybody,
    I've recently run into a strange intermittent sound problem. Occasionally when trying to play quicktime files on the internet, the video has no sound. This has also happened with YouTube files and I'm not sure what's wrong. I know the files have sound because if I download them, they play fine in VLC and on other computers. Is there some kind of sound setting that I'm missing? Thanks.

    When downloaded, have you tried them in the QuickTime app? Do you have a fast internet connection? :)

    Wow thanks for the quick reply. I have a cable connection at home, and DSL here at work so I don't think that's the problem. Yes I have tried them in the QT app, whenever I'm having the problem, they do not work either on the internet or in the app (after being downloaded). Then sometimes without restarting, a QT file seemingly the same as the others, will actually play sound. I guess this is a hard problem to troubleshoot, I just figured I'd see if anybody had run into anything like it. Thanks.

    P.S. I checked my MIME settings. The only ones I have checked are 1)Streaming, 2) Video only and Video with Audio File Formats, and 3)MPEG.

    EDIT: See this is what's weird. I have a QT movie trailer from Apple's site open and it's playing sound, then I have a You Tube file open and running next to it in another window. I stopped the QT file with the audio just in case I can only have sound on one. But the other video is still silent. My friend showed me this file on his Mac, so I suspect something is wrong.

    This problem seems to not be limited to quicktime. In my case quicktime audio works, but when watching flash movies (such as the NYT science movies) or real player movies (such as BBC news) I get no audio. Perhaps our problems are related?

    It's definitely possible. Hmmm, do you have links to that stuff that doesn't work? That way we could figure out if it's the same thing. I'm on a Macbook Pro. Also, is it possible that XML data has anything to do with it? Most of the time now when I go on the internet, my startpage (.Mac page) says .Mac is unable to retrieve XML data... Now this is driving me nuts!:)

    EDIT: That's gotta be it, XML problem. I found an NYT video and it doesn't play sound. How do we fix this?

    So I posted my problem on the Apple Support Discussions page and they helped me out. If you were having the same problem I was, all you have to do is quit Safari, open up GarageBand, play around with it a bit (not sure if that's really necessary), quit GB and relaunch Safari. The sound is there! Thanks for everybody's help.

    I had the same problem. The GB trick worked. Something with the Flash plugin (tried re-installing that first, didn't work). Weird.
