Sound Played through 'Dummy Output'
 

Hey,

I am running a Dell Dimension 9100. Here is a screenshot of what I see in 'Sound' (if it works)

I have pulse audio volume control installed along with gnome alsa mixer, gnomemixergui, and volti.

As the screenshot should show, I apparently get sound through 'Dummy Output'

I had sound before but did a reinstall because I had a problem with Zorin freezes up on me. That issue was solved but since then no sound.

I checked the box concerning downloading third party software on the installation page. I have installed the current 'Nvidia Driver (304).

From 'lspci' I got this:

Then with 'lspci -v' this showed up:

I have no idea what all that stuff means, but perhaps someone can make heads or tails out of it?

This usually means that Linux can't find a sound card, but it being found in lspci kind of rules that out.

Try the following based on commands that I found here and here:
