Possibly not helping a lot:

I have a T510 thinkpad with Intel HDA audio, running Windows 7.
I need to have the audio driver *and* the modem driver installed for any  
sound to work.
So possibly the modem part has to be initialised or something.
You have "no driver attached" on your modem, so maybe that's worth looking  

You could also try if sound works from a terminal without running Gnome at  
just to be sure it's not some Gnome configuration thing.
