A a possible fix:

12.04 sound problem fixed

if 11.10 was ok for you, just use the 11.10 kernel, i used 3.0.0.20, check the link.

AND after that if you still don't hear anything do this steps:

SystemSettings -> Sound -> (Select output) SPEAKERS, NOT HDMI.. 

(what is worng with this Ubuntu dev guys... I never used HDMI output, 
make that setting seccondary, let me hunt how to enable when i need that crap... J)

P.S.  what do you think fossfreedom  is this post ok?  comments should also be left, are the only feedback to developers, if they care.

No sound in Ubuntu except at log in
I'm a little confused, I realize hosting co. are there to make money, but why is it that RAM is so cheap these days and the monthly cost for just adding more ram is so much?

why doesn't someone come out and just break even on RAM and destroy the market? (someone has to, I mean there are so many companies...)
