no sound @ Xfce4.10 & FreeBSD 9.0 Release

[Takashi Fujita]

FreeBSD 9-Release is installed on M9686J/A Mac mini G4 1.25GHz.

/boot/loader.conf:
sound_load="YES"
snd_ai2s_load="YES"

cat /dev/sndstat:
FreeBSD Audio Driver (newpcm: 32bit 2009061500/powerpc)
Installed devices:
pcm0: <Apple I2S Audio Controller> (play) default

However, a sound is not outputted.
How does a sound come to be outputted if it carries out?
