Hi JR, > > guacl@bsdhost:~% tail -n 1 /etc/sysctl.conf > > hw.snd.default_unit=0 > > This is fine, but 0 is the default value, so you don't actually > need this. You only need it for value of 1, 2, 3... Alright so I can now forget this file. > /boot/loader.conf and /boot/loader.conf.local are used together. > I suggest you leave loader.conf as installed by the system, and place > all your config in loader.conf.local, although that is not so important. Sorry, /boot/loader.conf was blank right after installation.

I have already put them in /boot/loader.conf.local. guacl@bsdhost:~% mixer Mixer vol is currently set to 75:75 Mixer pcm is currently set to 75:75 Mixer line is currently set to 75:75 Mixer mic is currently set to 0:0 Mixer mix is currently set to 0:0 Mixer rec is currently set to 75:75 Mixer igain is currently set to 0:0 Mixer ogain is currently set to 50:50 Mixer monitor is currently set to 75:75 Recording source: mic guacl@bsdhost:~% cat /dev/sndstat 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. -- Gua Chung Lim Please help donate to Japan. -- for earthquake, tsunami and nuclear radiation reliefs (2011)
