The distortion is noise in the music. The music does not stutter or stop.
It's a high-toned noise in the music. It's not there every second, but on
average 30 seconds in every minute. It seems to be dependand on the kind of
calcultions seti is making.

The noise seems to have nothing to do with X11, because in console mode
running the seti client and mpg123, results in exactly the same noiselevel as
in X11.

I've tried 2.4.3-pre{3,4,6}, 2.4.3, 2.4.4-pre5 and 2.4.3-ac11, they al have
the problem. Only 2.4.3-pre{1,2} did not. 2.4.2 has also no problems.
