Alright so I can now forget this file.

Sorry, /boot/loader.conf was blank right after installation.
But it doesn't matter anyway.

I have already put them in /boot/loader.conf.local.

FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <HDA Realtek ALC662 PCM #0 Analog> (play/rec) default
pcm1: <HDA ATI R6xx HDMI PCM #0 HDMI> (play)

Yes, pcm0 is now what we are expecting.
Now I can hear sound from the speakers via /dev/dsp0.X
using C code fprintf(dsp, "%c%c%c", 7, 7, 7);
(I'm only on console.)
But how can I hear the sound without redirecting to /dev/dsp?
This area is VERY FAR from my knowledge.
I think I must completely read sound(4) and snd_hda(4).

Thank you very much again.
