[arch-general] Alsa/Pulse not using sound cards?

Hi, My system's sound is no longer is working. No, it's not muted, the sound modules are loaded, and there are pcm's in /dev/snd but no /dev/dsp. Also, while alsamixer does show the sound cards, it is only using the null device, and pulse audo doesn't see the sound cards either. Anyone know why alsa might not be using the soudn cards?
