nvidia-current is the meta-package for the proprietary nvidia drivers.
Those will only be guaranteed to work with the kernel in the main repo.
The Natty -lowlatency from the PPA is a Ubuntu kernel, and will work
with Natty drivers.
I believe nouveau drivers will work on all kernels, but I'm not sure,
since I haven't tried it. My packages are called
xserver-xorg-video-nouveau and nouveau-firmware. Don't think those will
be active if you have the proprietary drivers installed as well.

I hear that this fix will work for Natty, so if not for Maverick, that
seems strange to me. Did you make sure to reboot and look on what you
could see in pulseaudio preferences? No luck?

If you want to mess around with external kernels, you'll need to mess
with nvidia drivers too.

There's a lot of faders there. By this time I'm sure you know the gains
are named: adc 0-7 for audio-to-digital and dac 0-7 for digital-to-audio.
Not nice not knowing which faders to pull when just trying to get sound out.
Jack is not affected at all by the issues with pulseaudio, since it uses
alsa directly, so running jack with that card is a good way to start, to
make sure the card works.
