Com.apple.audio.coreaudiod error on every startup

Question

Hello,
I was does some system cleaning and maintenance and noticed that every time I start the computer, I get an error in Console:
com.apple.audio.coreaudiod     106: _RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() in NULL
And then it does it again right away:
com.apple.audio.coreaudio{106]     _RegisterApplication(), FAILED TO establish the default conncetion to the WindowServer, _CGSDefaultConncetion()is NULL
I was wondering what this means and how to keep this from happening. Since it involves core audio, this could be a potentially annoying problem if it has other effects (that I might see later), because I do music production.
I am using 10.6.8 on an early 2011 Macbook Pro and primarily use Logic 9.
Also does anyone know if I can prevent PACE and Digidesign/Avid stuff from running on every startup and just when I actually use ProTools or other PACE-protected programs?
Any ideas? Thanks!

Sorry I shall explain.
iMac been running very sluggish since Snow Leopard installed. Programs take ages to load. Freezes in OS and spinning beach ball all the time as well.
Did a search about a warning that get popping up which unfortunately I can not remember (sorry) but something to do with sound cdsa ? That's not right but searched and kept getting the same advice :
http://www.google.co.uk/search?q=com.apple.audio.coreaudiod.plist+error&ie=utf-8 &oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a
Ditch the com.apple.audio.coreaudiod.plist
Did this and the iMac ran at super light speed. Applications opened really quickly no beach ball at all - but no system sounds, emptying trash etc.
Dropped com.apple.audio.coreaudiod.plist back in LaunchDaemons Repaired Disk Permissions and got my system sounds back but got the beach ball back too and slow performance and crashes freezes etc.
Any advice would be great
