Thanks for your tips!
I have tried, but the result is all the same.
Here is my ALSA_PCM_PLUGINS: (I have also tried your choose too)
ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty
extplug file hooks
iec958 ioplug ladspa lfloat linear meter mulaw multi null plug
rate route share shm softvol"
Here is my in-kernel alsa options:

Here is my /etc/modules.d/alsa:

I can't find the /dev/dsp :

ls: cannot access /dev/dsp: No such file or directory
My os is a 64bit gentoo, so may it be the problem?
