I wondered if Daniel Chen's suggestion was for Martin or me (Nick). Anyway, I tried it, and installed linux-alsa-driver-modules-2.6.32.-22-generic from ppa:ubuntu-audio-dev but after a reboot, the shutdown still made the horrible noises. I assume that since Windows can avoid this problem, it must somehow be setting the sound card's output to zero before the final shutdown, so that any audio interference arising from the power supply turn off never reaches the amplifier. I'm sure if Windows can do that (whatever THAT is??!!) then Linux could do it to.
