Setting Audio Out to Line Out rather than internal Speakers - Not sticking

[milbournosphere]

So I have my '10 Pro setup with some Logitech speakers to use as audio out. I have gone into the preferences pane and set the sound to go through the speakers, rather than the internal speaker. All is well until I reboot the machine; the setting does not appear to be sticking after a restart. Any ideas?

Sorry for the bump on this, but I'm having the exact same problem on a 2006 Mac Pro. Any solutions?

Same here on a 2006. If I go into Sound Settings on Systems Preferences it starts working again. Weird.

Still haven't found a solution to this...does anybody out there have one? I'm only bumping because at least a few people besides me are having this problem. I know it's not the speakers. I just upgraded to a set of creatures, and I am still having the problem. Any ideas?

Hello,

Usual suspect: preference file not allowed to be properly saved. Have you guys repaired your permissions lately?

Check this thread out, it worked for me.

Problem solved. Here's what worked for me:

1) Trash your /Library/Preferences/Audio folder

2)

sudo mkdir /Library/Preferences/Audio/

3)

sudo chown -R _coreaudiod:admin /Library/Preferences/Audio/

This should trash and reset you audio preferences. Probably some issue from when I migrated my data over from my old box. Anyways, problem solved! Off to listen to some Pink Floyd. Thanks for all the help, as usual these forums are great.
