Now it's better, I can hear voice both from the speaker as well as 
in the headphones. Better for me since I can just unplug the

$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2007091800/i386)
Installed devices:
pcm0: <Intel 82801G High Definition Audio Controller> at memory

channels duplex default)
