[PD] soundcard noise

[Yogi]

Aaa...
Ok I am not 100% sure about this but this is what I think and wha ti
have herd:
Actually I think the noise is because the system bus gets clogged when a
lot of video is going through the bus which is common when you are
draggin windows or scrolling in IE.
It’s a common problem on laptops where the bus speed is pretty low (to
save power)
I don’t really know what u can do to stop it apart from try not to do
oto much video activity.. and use keyboard as much as possible for doing
the windowing gui stuff.

And also you might do a

chkconfig --list
and see which un-needed progs might be running in the bakround that you
do
not need
it matters what kind of Box you are running but i was able to shut off
about
10  memory residents which made a nice difference

chkconfig --level 5 name_of_prog_hog  off
