QuickTime player 10.2 does not record audio, mic works in other apps

Hi,

OS: Mountain lion

QT player: 10.2

Perian and Soundflower are installed.

QT is not recording audio from the computer mic or even a headphone mic, neither for audio or video recording.

QT starts always for recording with the volume down.

The mic works in other apps (skype or garaband).

I am not able to find either the plist files for QT.

I used QT in the past to record audio from the computer mic.

I recently updated the OS from lion to mountain lion.

Any ideas why is not working?

Thanks!

MacBook Pro, OS X Mountain Lion (10.8.2)

Preferences files (plist) in /User/Flope/Library/Preferences/

QuickTime Preferences

com.apple.QuickTimePlayerX.LSSharedFileList.plist

com.apple.QuickTimePlayerX.LSSharedFileList.plist.lockfile

com.apple.QuickTimePlayerX.SandboxedPersistentURLs.LSSharedFileList.plist

com.apple.QuickTimePlayerX.plist.lockfile

These are some errors in the console. Not sure if related
