As a workaround edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf :
gksu gedit analog-output-headphones.conf
Than search for and comment this line like here:

Save the file and close gedit. Than restart pulseaudio with:
pulseaudio -k

and there I was able to
I still get an error message everytime I save regarding a root file that does not exist, but it doesn't look like it's impeding the save process at all.
Open a terminal end type:
alsamixer
Play around with the bars. Use arrows to switch left-right or up/down to higher/lower the volume.
Your headphone output is probably muted. Open the sound control panel and check that you don't have any outputs muted.

Downvoted because?? I've had this problem, and it was exactly the case that my headphone output was muted. Not saying it's the answer every time, but worth checking.– djeikybMar 28, 2011 at 6:01
