I'm having a similar issue. I am running ubuntu 11.04 off of an intel machine. I get sound through speakers but not through headphones. I've already checked that all the sound fields are cranked in alsamixer. I've tried switching the output type to analog headphones, but to no avail.
Using the alsa info script, the following information is generated.

If any one can help me. I would greatly appreciate it.
