Why do my sound output settings keep resetting after restart?

Just bought a MBPro with OS 10.6.4.
After restarting my sound output settings keep resetting to Soundflower (2ch) from Internal speakers.
It doesn't take too much to change it, but it is pretty annoying and I'm assuming there's some obscure setting that can fix this.
Anyone able to help?

Macbook Pro, Mac OS X (10.6.4)

This fixed it on my Mac Pro. It might work on a MacBook Pro.

Delete these three files:
/Library/Preferences/com.apple.soundpref.plist
/Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist
/Library/Preferences/Audio/com.apple.audio.SystemSettings.plist

Reselect whatever sound device you want as your default in the Sound Preference Pane.

Restart the computer.

Thanks! That appeared to do it. When I looked at the files, there were duplicates of
/Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist
/Library/Preferences/Audio/com.apple.audio.SystemSettings.plist
with the ending ~orig created at the same time, so I don't know if that was confusing things.
Anyway - thanks!

That's good. I don't even have those files on my computer. Have another idea?
