Thanks for picking this up. I have found a temporary fix for 7.04.
Manually unloading all sound-related modules (snd-hda-intel, snd-hda-codec, soundcore, etc.) with "modprobe -r" prior to issuing "shutdown -h 0" seems to fix the problem.
Nonetheless, I will try to find a more elegant solution with the 7.10 LiveCD.
