Not too sure how to put this.  The lappy is dual boot, and of course
works perfectly under win7.  Pavucontrol lists the 4 spidf out puts
which belong to the Nvidia card, and in the correct order.
I can choose the nvidia sound driver under alsa mixer, and it outputs to
the internal speakers/headphones etc.  
Note Ric No hardware issues.

What I can't get is Hdmi audio output.  Basically that means when I hook
the thing up to the tv, I have to use windows,  Not a major issue, just
that I much prefer to us Ubuntu/

Have googled extensively,  and at the moment am following the
information at   ftp://download.nvidia.com/XFree86/gpu-hdmi-audio...
and working my way through the information posted there.

Also have followed the information here
Audio/InstallingLinuxAlsaDriverModules - Ubuntu Wiki
To up date the Alsa driver to the latest version.

After doing this, I was able to access the nvidi HDMI audio output, so
maybe with a little more tweaking I can get it to work.

Given the use of laptops these days I would have thought that the devs
would have had this issue sorted by now.  That is just an opinion mind
you.
