lspci shows the following:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High
Definition Audio Controller (rev 01)

Yes but is not very good - I got a lot of clicking noises when I use
Hydrogen without Jack running, Alsa Audio driver reports Xruns.

Unfortunately that didn't make a difference. I fiddled with the BIOS
settings for the laptop, which seems not to have any change. I also
checked for the Centrino CPU scaling, even if I set the CPU to
"maximum performance" using Klaptop, it didn't make any change.
I seriously started to wonder about giving up on the internal sound
card and looking for a USB one. :)
With strace, I see the following before it dies, if it is helpful:
stat64("/dev/shm/jack-0/default/jack-ack-fifo-23837-1", 0xbf83afb0) =
-1 ENOENT (No such file or directory)
Here's the full strace output for the command line for Qjackctl
reports when I run it myself:
