You need to enable the sound card emulation on the VirtualBox side. By default it's turned off.

Also note that vboxsf doesn't work on FreeBSD. There is no "shared folder" support with the FreeBSD guest additions.

The sound card emulation has been enabled:
Driver: Windows DirectSound
Chip: ICH AC97
If i changed it to Intel HDA, then freebsd will be flooded by "interrupt(21) storm" why is there so many interrupts when i donot use sound ?

BTW,
Do we still need the FB guest If no "shared folder" ?

That depends, if you want a "seamless" mouse and use Xorg properly, then yes.
