Before few days I install some updates to my Ubuntu 12.04. After those updates I have not any sound. When I use older kernel 3.2.0-23 all is OK I use i386 version Ubuntu.

petat@mujlin:~$ aplay -l
aplay: device_list:252: žádné zvukové karty nenalezeny...(any sound card found...)

but

petat@mujlin:~$ lspci -v
