You might be interested in this article:

I had beaucoup problems with that system, but eventually I got it fixed
up for audio. Btw, I installed it on my HP G60 notebook, as per the article.

I picked up a contract to review some software on Karmic, so I upgraded
the notebook to 9.10. The upgrade went well except for a few relatively
minor problems. The default choice for grub's menu.lst didn't add the
new kernels, but I was able to fix that with a little googling (and
installing grub2). And as usual Ubuntu doesn't add the user to the audio
group, another easy repair. Finally I had to fix /etc/init.d/umountfs to
permit a full shutdown (i.e. without having to push the power button on
the machine). See Google for details.

I've done some very light testing with JACK under the normal kernel. I'm
impressed, so now it's on to test the rt kernel.

Best,

dp
