Strange broken sound during start-up and wake-up, a annoying sound happens here.

[kidalive]

After getting my sound fully working I noticed every time when I start up the Leopard there is a crack assertion sound during I change the volume or play a song using the iTunes. It`s like the sound card is broken yeah it like a broken sound seems like something damaged the sound card. I dunno what it is. But this annoying sound disappear after that, it`s very strange. Do u guys have the same issue there? One more problem is when I browsing webs using the safari and playing songs using the iTunes the iTunes seems have a random pause out there. What is the fix,

guys?

 

And a few errors like this

_CFGetHostUUIDString: unable to determine UUID for host. Error: 35
