I ran into a no sound issue after upgrading from 10.04 to 12.04.  In
my case, the problem was my Nvidia video card with an HDMI output.
All the sound was being directed to the HDMI output instead of the 3.5
mm jack on my on-board sound card.

To fix it, I went to Multimedia->Pulse Audio Volume Control
then click on the Configuration tab,
then set "High Definition Audio Controller" to "Off" and made sure
"Built-in Audio" was set to "Analog Stereo Output".

You might then want to check the "Output Devices" tab and make sure
the port is set right and it isn't muted and the volume is turned up.

Mine all looked fine in alsamixer and everywhere else before I did
this as well, but as soon as I disabled the other controller, sound
came on right away.

Hope this helps,
