Default Maverick and Delta 1010lt UPDATE

So, here is an update to the Maverick and Delta 1010lt saga.

Did a fresh install a couple of days ago. I didn't have time to look
into what was working an wasn't working that night so after the
initial install I shut down the machine. I got back to it last night
and low and behold sound was working without out any modification
other than turning up the volume. I have the on-board card working for
system sounds etc and after setting Jack to use the 1010lt I was able
to get sound through it with Hydrogen for a test.

Very strange how it just worked this time. I was thinking I would need
to implement the following for Jack, but didn't need to. I may need to
add the fix for PA to see the 10 channels, but I'll work on that
later.

/usr/share/alsa/cards/ICE1712.conf)...


#

<confdircm/front.conf>

ICE1712.pcm.front.0 {

ttable.1.1 1
slave.pcm {
type hw
card $CARD
}
#### fix PA issue ####
slave.format S32_LE
slave.channels 10

}

Right now the machine is just using the kernel from the default
repositories so it is the generic kernel. As far as I can tell the
machine is using the nouveau driver for Nvidia. I'm getting the
typical problems of X freezing (except the mouse continues to work)
and various pixels turning either red or blue.

So, I'm not sure which route to go in getting the nvidia cleaned up
and stable. I would like to use one of the lowlatency kernels
available here: http://launchpad.net/~abogani/+archive/ppa. Not sure
the effect of that on Maverick and with the nvidia card.

Any suggestions on how to proceed with the nvidia drivers and
lowlatency kernel without blowing up what is already working?

Thanks for the great help so far.
Brian
