I have updated my -current to March 29, apply the patch above.
However, it does not solve my problem.

pcm0: <Intel ICH4 (82801DB)> port 0x1c00-0x1cff,0x18c0-0x18ff mem
0xc0000c00-0xc0000dff,0xc0000800-0xc00008ff irq 11 at device 31.5 on

pcm0: sndbuf_setmap 1f105000, 4000; 0xd58eb000 -> 1f105000
pcm0: measured ac97 link rate at 47994 Hz, will use 48000 Hz

(I tried put them in loader.conf, result is the same)

I use modules for snd_ich and sound.

Hope the information above might help. If you want more information
from me, just let me know :)
