I solved the problem. The fact that all the systems affected by this problems are Dells made me think about something related this family of machines. I had personally added to the repositories the ppa's one ( http://ppa.launchpad.net/dell-team/ubuntu ) dedicated to dell systems (in my case to enable 56k modem functionalities). It is a known issue of kernel upgrades to loose sounds and a workaround is also given by the dell-team. http://linux.dell.com/wiki/index.php/Ubuntu_8.04/Issues/No_Sound_After_Distribution_Or_Kernel_Upgrade
Hope it could be useful.
