Fresh installation of version 14.04 64-bit on a Sony VAIO. Completelety reformatted HD. Single OS system. No sound of any kind. But there is sound from plugged in headphones. Everything is unmuted in Sound Settings. I don't see any Hardware tab there. In the Output tab there are 2 options: Digital Output S/PDIF (Built-in Audio) and Headphones (Built-in Audio). It looks like Ubuntu doesn't see my sound hardware (most likely it is a sound processor built into the motherboard and not a stand alone sound card).
I ran pacmd dump-volumes
command and got this:

Any suggestions will be greatly appreciated, but I would prefer as many details as possible since Ubuntu is totally new to me.
