Recently I installed Ubuntu 10.04 64-bit in my Sony VAIO machine and I figure out that speakers are totally disabled. At first I thought that the volume was to low, but that wasn't the case.
I even update and upgrade, but the problem remains.
Any suggestions would be greatly appreciated!
Executing the command lspci, I get the following output:
