[list=] I have just performed a lean install of ubuntu 12.10 on a Dell Studio Hybrid g140.
No sound, tried alsa mixer with no results.
Only once, my little daughter playing internet games with the chrome browser (in my absence) reported that she had clear sound. i was unable to repeat the experience.
Previous installs of ubuntu (9.04 onwards all worked fine). Only suffered from temporary sound problems solved through alsamixer
This is a double boot machine and no othe linux distro (mageia1,2, fedora15-17, sabayon) has ever experiecnced sound problems (or any other hardware problem for that matter).
run the alsa project test as advised

Thank you for any advice
PS I have used English insted of Greek in case this might also profit from on-greek speaking help
