nvidia drivers won't work if you use a kernel that is not meant for
Maverick. I assume you are using a kernel for another distro.
nvidia drivers can be made to work of course. You would either need to
build them yourself, or add them manually from a repo that matches the
kernel (I would believe), however, I would not recommend you to do this.

Unfortunately there is a problem in how the ice1712 is presented to
pulseaudio. This is why you get no desktop sound, but it should be easy
to fix.
To copy what Ralf wrote in another post on this list (edit the file
/usr/share/alsa/cards/ICE1712.conf)...

ice1712 will always work with jack. You might have neglected to raise
some volumse at first. An easy mistake to make, which I have made myself
many times.
Did you check out envy24control? It is a mixer for ice1712 cards. I
recommend to use that.

I can understand your frustration. I have went through the same thing
myself. Unfortunately the problem with getting ice1712 to work with
pulseaudio has been a long lingering problem (3 years and counting, I
think).
I'm hoping Ubuntu Studio 11.10 will include a way to fix this, if yet
not fixed on regular Ubuntu.

 However, I still have no sound via the system. Any ideas on what

There will be no -lowlatency included in Natty's repos. There is one
available here: http://launchpad.net/~abogani/+archive/ppa.
The -generic kernel is quite good on Natty, and hopefully that will
already be enough for many people.
