(SOLVED) Defaulting Sound output ?

[Washac]

Problem solved and this may help others with this problem.

As a last resort I copied the Audio folder from another Mac I have running 10.6.8 onto my Mac Pro, it worked it solved the problem

Do not know if copying that folder from different OS would work.

Hope this helps somebody.

2009 Mac Pro 10.6.8

Just recently my Mac pro defaults to the Internal speaker when I restart or reboot, I have to go into Prefs to set it to Display Audio.

I have already tried deleting - com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist and even the Audio folder itself, then re booting and re setting the sound output, but on next restart/bootup it defaults back to the Internal speaker.

Tried resetting the PRAM also, still defaults to the internal speaker.

Also tried this :
Delete Audio Folder
sudo rm -r /Library/Preferences/Audio

Recreated a new one:
sudo mkdir /Library/Preferences/Audio

Change the permissions:
sudo chown -R _coreaudiod:admin /Library/Preferences/Audio
Then go back to the sound preference panel and set the audio to the one you prefer. This will recreate the settings file.

Still defaults to internal speaker.

And these :

Repaired HD via Disk Utility
Repaired Permissions

Still defaults to internal speaker.
