Default FreeBSD 7.2 amd64 snd_hda no sound

I tried to listen audio cd with cdcontrol program but I get no sound at all. My cd-drive is connected to sound card with a audio cable. Playing mp3 file from command line doesn't work either I tried mpg123 program no error messages. Any ideas why sound is not working?

Code:
$ uname -a
FreeBSD freebsd 7.2-RELEASE FreeBSD 7.2-RELEASE #0: Fri May  1 07:18:07 UTC 2009     root@driscoll.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

Sorry I've been giving wrong information. I can hear music when I play mp3 file from command line. Sound works when hw.snd.default_unit is set to 0
I get no sound when using cdcontrol.

Have you tried increasing the volume on the ones that are low? Perhaps the cd audio is coming in on the 'mix' channel.

Most of us don't other with those audio cables any more. CDs audio is usually played by the computer. You PC will be able to do much better DAC than the chipset inside the CD drive.

Yes I have tried to increase the volume.

Code:
$ mixer
Mixer vol      is currently set to 100:100
Mixer pcm      is currently set to  75:75
Mixer speaker  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 100:100
Mixer rec      is currently set to   0:0
Recording source: mic
You were right cd audio is coming from mix channel but It's so quiet. I can barely hear the music playing.

Code:
$ cdcontrol volume
Left volume = 255, right volume = 255
Any ideas?
