Sudden Loss of QuickTime Audio, missing component?

[MacManX206]

Suddenly my QuickTime's ability to play audio has flow through the window. Every single file I open in QuickTime player now pops up an error window which displays "You may experience problems playing a soundtrack in "(file name)" because a software component needed by the movie could not be opened. Would you like to close or continue?" This is the weirdest thing I've seen. This is happening on any file with an audio track; from movie trailers, to fan films, to plain AIFF files and MP3 files. The QuickTime plugin loads sound and movie files without error, but doesn't play any sound during playback either. iMovie is similarly affected. iTunes does continue to function properly, as do VLC and MPlayer. I doubt it's something I installed since I haven't installed anything for about two weeks. I've run Disk Utility (including Repair Permissions), all three cron tasks, cleared the log archives, the system cache, the user cache, and the internet cache, updated prebindings, and rebuilt the directory (at least my system is faster now). I've also deleted every last QuickTime preference file, QuickTime Player, and the QuickTime Plugin. After that, I reinstalled from the downloadable installer. Nothing has worked so far. The problem is system-wide and affects all of the user accounts. Any ideas out there? Does anyone know how to uninstall QuickTime? Thanks in advance.

Update: Still no go.

I got impatient with myself (that's me, always tinkering) and completely, yes completely uninstalled QuickTime. Basically, I just kept deleting files, restarting, and reinstalling QT. Each time it didn't work, I added another file (most "severe" files were last, of course). File that I trashed:
/Applications/QuickTime Player
/user name/Preferences/com.apple.QuickTime Player.plist
/user name/Preferences/com.apple.quicktime.plugin.preferences.plist
/user name/Library/Preferences/QuickTime Preferences
/user name/Library/Preferences/QuickTimeFavorites
/user name/Library/QuickTime
/Library/Receipts/QuickTime652.pkg
/Library/Caches/com.apple.Components.LocalCache.QuickTimeComponents
/Library/Internet Plug-Ins/QuickTime Plugin.plugin
/Library/QuickTime
/System/Library/Caches/com.apple.Components.SystemCache.QuickTimeComponents
/System/Library/Components/AudioCodecs.component
/System/Library/QuickTime
/System/Library/Frameworks/Quicktime.framework

As you could probably guess, trashing the QT framework hosed my system. I was able to recover by replacing it with the file from my unaffected PowerBook. In my last attempt, I deleted all of the above files, restarted, replaced Quicktime.framework with a copy from my unaffected PowerBook, installed QuickTIme from the standalone installer, and there is still no change. I don't think I missed any QuickTime files. Any more ideas out there? I'd rather not to a reformat and install (though I almost had to tonight).

Well, it turns out that all I had to do was launch GarageBand. Apparently, Launching GB resets some CoreAudio settings. That's probably a GB bug nonetheless, but it certainly saved me.

I had the same problem and I also noticed that Real Player had no audio either. This is with OS X 10.3.8. If I tried to open an mp3 or Flash with audio file with Firefox, I just got these messages on the Console:

/Applications/Firefox.app/Contents/MacOS/firefox-bin: can't map file: /Library/Internet Plug-Ins/QuickTime Plugin.plugin ((os/kern) invalid argument)

/Applications/Firefox.app/Contents/MacOS/firefox-bin: can't map file: /Library/Internet Plug-Ins/Flash Player.plugin ((os/kern) invalid argument)


It took me a whole day of deleting and reinstalling until I came across this post and fixed it. Thanks!

Any chance you could detail your solution? I just ran into the same thing on a 10.3.9 iMac G5 17" with a gig of ram. I've tried reinstalling QT, repairing permissions and even repairing the disc from an OS X cd. Any help much appreciated!

I was having a problem where all flash & streaming quicktime audio (just streaming not local playback!) was being sent to by usb headset not my default audio device and you're tip of opening up GB fixed it.

Thanks a lot, thats the first time I've opened GB in the 4 months I've had my mac so chances are I would never have found the solution!
