Hello everybody,

I have a problem with my Ubuntu 11.04 (natty), here is the problem; when I wake up from suspend or hibernate mode, I can't hear any sound even if the volume bar set to maximum. My PC is a Fujitsu Siemens Pi 1536, here the result after taping the command "lspci".

00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
Anyone can help !!
