"no soundcards found" after Debian upgrade

[Menashè Eliezer]

Hello, I have /Debian testing/ in which the sound was fine. Few days 
ago, after an update, I have "no soundcards found" with "aplay -l". 
lspci: "00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series 
Chipset Family High Definition Audio Controller (rev 04)". I've tried 
everything and searched everwhere. I prefer not reinstalling the OS. I 
hope someone can help me.

Thanks,
Menashè
