Re: No Sound on thinkpad T530
I'm having the same problem, on a Thinkpad T410.
Sound worked fine until December 2012. Not sure what prompted the failure. Since then I've updated to Ubuntu 12.10 and it remains a problem.
In Ubuntu: no sound from the speakers, but the headphones work fine.
What is strange is that I am ALSO having sound problem when I dual-boot into Windows. There the speaker audio works *intermittently*. The sound will come on for a few seconds after I change the volume using the +/- buttons above the keyboard, but then it stops working again.
Re: No Sound on thinkpad T530 - fixed?
It turns out that doing "killall pulseaudio" is a (temporary) fix. If I kill pulseaudio and then use the command line speaker-test program, it *works*.

Next question: what's wrong with pulseaudio?
