[CentOS] Server hangs initializing audio

I have a server that frequently hangs while rebooting.  I see no
errors, but during the boot process it stops at this stage:

    Initializing hardware... storage network audio

The cursor sits just after the word "audio" and I have to do a hard
reset to get out of it.  This server has no audio capabilities, so I
am thinking that I just need to disable the audio stuff so it doesn't
even try to load it, but I don't know where to look.
