Audiosurf doesn't detect QT

[checkers]

I just installed Audiosurf on my Win7 machine, and I can't play my .m4a audio files that worked fine in Vista. When I try to load a song, I get the following error message: "Quicktime is required to play the song you selected, but it isn't installed. Get quicktime here (free) : www.apple.com".

I have a perfectly vanilla itunes+qt install on my machine, the only thing I might have done is played with QTs file associations. I can launch QT fine and play my audio files directly in that.

Any suggestions? It would be nice to know how audiosurf detects the presence of QT, because I might just be able to fake it.

EDIT: Tried validating my game cache in Steam. It finds 4 files to update, but QT still isn't detected.

EDIT2: Reinstalling the game didn't help either

Find the "iTunes Decoding" box and reverse it's status. (If it's checked uncheck it, and vice versa)

Doesn't help sadly, the checkbox seems to be only for MP3 as it says.

or just get a codec pack that work with m4a

i dont have itunes or QT and i can still play m4a's and aiff's

I don't have QT, or anything apple for that matter, and they work for me, try using codec packs such as CCCP or K-lite or QuickTime Alternative

EDIT: DO NOT install more than one pack at a time, as bad things will happen

I still don't know why this is happening to some people, but this workaround has done the trick (once at least):

Right-click QuestViewer.exe (in
steam\steamapps\common\audiosurf\engine) and choose "create shortcut".
 Then right-click the shortcut and select properties.  At the end of
the Target field, add " Q3DStart.q3d" (with the leading space, but not
the quotes).  Hit OK.  Now you can double-click the shortcut to launch
the game.  Right-click the shortcut and change settings on the
compatibility tab. Set it to run as administrator.

Also, If you have 32-bit iTunes (and Quicktime) installed on Win7 64-bit, that could be the problem.
