Sudden odd problem with KDE sounds

Yesterday when I booted my computer, I could not start the KDE sound server. I created a new account to see if it was my configuration files (even though I hadn't changed them), and it didn't couldn't start the ARTS sound server either. I get the error message:

Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (Invalid argument)
The sound server will continue, using the null output device.

However, when I change the Sound System source from either "Autodetect" or "ALSA" (my usual settings) to "OSS," I had KDE sounds (the ARTS server) in both accounts. (By the bye, I had sound in all my applications, such as amarok, mplayer, and xine, even when I didn't have the ARTS server running.)

However, if I sign in as root, I have sound under "Autodetect" and under "ALSA", so that suggests some permissions problem. However, I am in the audio group, so that isn't the issue. One thing that may help: I was fooling around with hal and dbus the night before, although I don't believe I ended up making any changes other than commenting out entries for my DVD drives in /etc/fstab.

Obviously, any help would be mightily appreciated. Stubborn me was at the keyboard for four hours last night and made absolutely no progress!

My kernel is 2.6.21, the alsa drivers are from the kernel, and I'm using alsa-lib-1.0.14. My distribution is gentoo, and all packages have been updated within the past week.
