Thanks for your quick reply. I tried the above and playback is still
fast, changing it to any number doesn't seem to do anything. I also
cannot set it with loader.conf. I have to do it manually after the
system is loaded, Is this normal? Here is what I have in loader.conf:

sound_load="YES"
snd_ich_load="YES"
hw.snd.pcm0.ac97rate=48000
hw.snd.ac97rate=48000
hint.pcm.0.ac97rate="48000"
hw.snd.maxautovchans=4
