No sound at random starts

[persep]

Hi,
it's happen twice. I start the computer, it chimes ok, login with my user and I don't have the sound icon in the menu bar. The built-in Sound is ok in the system profiler and in the system preferences in sound I get no input or sound devices. I restar or shut down the computer and the sound comes back. in the system log this error shows:

I've seen in another forum that somebody fixed it reinstalling the 10,5,2 combo update but when I tried it, it says i don't meet the requirements.
Any ideas?

PowerBook 15" 1.5 GHz Leopard 10.5.2

I'm having the same problem here on a latest-gen iBook and I think it also happened once before 10.5.2.

Kind of annoying as I only reboot for Security Updates and stuff like that and I only realise it after I already fired up all my apps......

I've repaired permissions and so far so good

I had this issue on my 12" iBook G4 (last iBook before the MacBooks came out - 1.33GHz) and installing the 10.5.2 Combo update fixed it for me.
