I have a Creative Labs X-Fi Titanium on a PCI Express slot. Anyway, as
a side note, I didn't face any problem with the sound until 1 month or
2 months maybe.

So this could be related to the cpu scaling (which I started to play
with 2 months ago or so), but I need deeper tests to ensure this:
make the problem arise again and switch to cpu-scaling set to
performance and see if this changes this directly.

I have some few xruns sometimes (very few) as far as I remember it.

I'll let you know everything.
