I have the same problem, i am using ALSA on Karmic 9.10, started to happen after upgrading to the latest kernel for Karmic kernel 2.6.31-21-generic
when i boot up, the audio sometimes starts, then it doesnt work , some of my applets are also not loaded, it is as if it is booting too fast and audio drivers are not loaded
when i had compiz off, the audio loaded every boot, once i have it on, it stops loading again,
