It's probably because your sound card isn't known to Ubuntu, or needs a tweak ("quirk") in /etc/modprobe.d/alsa-base.conf

For example, Dell laptops often need options snd-hda-intel model=dell-m6-dmic to be added to the end of the file.

Look here as a starting point for your model.

This is probably a duplicate of Question 100.

Try using

In it's GUI interface there are several "PIN" options, if you click around "OUT" connector, you are able to forcefully turn on/off headphone and speaker configuration. That was the only solution what worked for me even with 2.6.36 kernel (I have Panasonic CF-R9).
