Please forgive me if these questions is already answered:

It seems that after the last updates my machine is now running the
generic kernel 3.5.0-33 by default. This seems to have broken JACK,
which was running without problems for a long time. So I have the
following questions:
- How do I "downgrade" so that the 3.5.0-31-lowlatency kernel becomes my
default setting?
Remove any package with generic in it's name. (should be 3):
linux-image-3.5.0-33-generic, linux-headers-3.5.0-33-generic and
linux-image-extra-3.5.0-33-generic.
You may also want to remove (if they are installed):
linux-generic, linux-headers-generic, linux-image-generic, linux, linux
image, etc. I can't remember which ones the upgrader uses to point to the
latest generic kernel. However, if you leave them installed, they may pull
in the next new generic kernel again.
- Why does Ubuntu Studio bother with the generic kernel anyway?
They don't. The upgrader is not a UbuntuStudio Project and seems to break
some things in UbuntuStudio. A fresh install just has the low latency
kernel... at least any of the UbuntuStudio versions I have tried ... all
of them from 12.04 to 13.10alpha. I, personally, have had other issues
with upgrades in Ubuntu Studio as well. Reinstall is best. (but then I
have been doing fresh installs since SlackWare 0.9.* or so... maybe I
should come out of the dark ages?)
Thank you! Makes me wonder how the generic kernel entered my system,
then, but not enough to investigate! I'll just remove the generics...
As for upgrade vs fresh install I never managed one successful upgrade
(OK, maybe I tried just twice ;-) ) so I prefer the fresh install.
Though I've broken a bone or two by leaving all the config files on my
home partition and then installing on the root partition. WOW, can it
break things...
