I had this same problem.

Laptop: ASUS F3Ke / X53K series

bash-3.1$ head -n 1 /proc/asound/card0/codec*
Codec: Realtek ALC660-VD

ash-3.1# lspci | grep Audio
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)

bash-3.1# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC660-VD Analog [ALC660-VD Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

This workFaround works for me for now, add following line to alsa-base.conf (the probe_mask=1 bit is important):
options snd-hda-intel model=lenovo probe_mask=1

Outcome: Still plays from speakers AND Headphones but now you can mute speakers in alsamixer mute the "Front" volume control then sound only comes through the headphones. =) I hope they fix this though.

Note I ran this on Slackware 13.0 but everything is the same also on Ubuntu.
