FreeBSD 7.2 amd64 no sound

[erim]

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?
